Preventive Maintenance Manual
Preface
The purpose of this manual is to assist your efforts in maintaining and protecting your new building. It is also intended
to help educate the new owner of the responsibilities of owning an engineered steel building manufactured by Nucor
Building Systems. Just as with a new home, your building will occasionally need attention to maintain current aesthetic
appeal, warranty coverage, weather tightness and proper working order of accessory items. The decision to buy an
engineered steel structure is not unlike buying a new car. You would not normally purchase a new car and choose not
to perform the routine maintenance. Likewise, you should not neglect the minimum routine annual maintenance of your
Nucor building. Proper and timely maintenance is an integral part of the long term success of a roof system or structure
in order for it to maintain it’s original design integrity. Proper maintenance is also required in order to preserve the
integrity of the Galvalume® protective coating of the steel sheets. Maintenance of the system is a requirement and
responsibility of the building owner.
The outcome of several recent studies show that while the upfront and long-term costs of a metal roof system is
significantly less than a built-up roof, there is still a certain amount of costs associated with routine maintenance. The
figure quoted ranges from $0.02 to $0.05 per square foot annually. There are other maintenance costs associated with
your Nucor Building. The most significant is the maintenance of the roof system.
Careful thought should also be considered to the mechanical systems, the insulation system, and the methods of
construction. This will decrease the possibility for the presence of condensation. However, the prevention and
elimination of condensation depend on the total design and construction of the building, which is beyond the
responsibility of Nucor.
This manual is broken into five sections. The first deals with the final walk through before taking ownership. This
section highlights areas of inspection that may eliminate later surprises. The second section deals with the annual
maintenance of the building and attempts to answer some of the questions that may come up. The third section deals
with the Annual Inspection Report. Performing scheduled annual inspections may be the best part of a preventive
maintenance program. Doing so identifies problems and provides correction as the situations occur. The fourth section
deals with Nucor warranties that have been issued on your building. The warranties issued by Nucor outlines the
conditions by which the product must be manufactured, stored, installed, and maintained. Section five contains
information about builders warranties, if applicable, and addresses the Builder’s responsibilities within the warranty
terms. Remember, a warranty is never a replacement for professional installation or reasonable maintenance.
The preventive information guide is available for your reference in order to practice routine maintenance. The
information indicated in this manual reflects the minimum standards for routine maintenance and your specific building
may require either additional special maintenance or more frequent routine maintenance, to which the determination is
based solely on common sense by the owner. Some information within this guide is provided which outlines some
Installation & Maintenance conditions that have been observed or experienced by building owners. In many cases, the
nature of issues experienced by owners was not associated with the manufacturing of materials, but rather how the
materials were stored, shipped, handled, installed and/or maintained. Some information provided in this section is also
related to outside product compatibility or improper design associated with materials that are not part of the metal
building system scope. Some of these conditions are to be expected on a structure. This information is intended for
additional information in order to help identify some common areas of concern so that they can be addressed or
prevented. This information guide is not a certification or endorsement from Nucor. Our mission is in no way to certify
erection methods or engineering for specific project issues due to installation or damage. If that service is required, an
independent, qualified consultant should be retained since the expertise of Nucor does not extend to these areas.
Services as aforementioned are not included in the scope of our order documents. Nucor Building Systems is a high
quality manufacturer of building systems which have been designed in accordance with order documents. We are not
qualified to act in the roll of the erector, General Contractor or Project engineer for the entire project. The contractor’s
failure to erect the building in accordance with the provided erection information shall not impose liability on Nucor.
This manual has been designed to be as user friendly as possible. It is not intended to replace personal interaction. If
you have a question on something that does not appear in this book or on a situation that is dangerous to human life,
consult your engineer of record, your Builder, or Nucor Building Systems.

Preventive Maintenance Manual
I. The Inspection
A. The perimeter walk
Take a walk around the perimeter of your building. Is there any “white rustâ€, dents or scratches on the panel? Is the
finish itself acceptable; are there any blemishes? Are the fasteners all in place and well seated? Are the flashings in
place at all locations? Are the cut ends de-burred and closed off where appropriate? Has the building been properly
made watertight? Are all of the small openings sealed against the elements, birds and rodents?
Are the downspouts in place as noted on the Nucor plans? Are they free of debris and well drained? Are there
provisions for removing the water from the base of the building?
Are the doors and windows functional? Is the correct hardware in place? Are the requirements of ADA regulations met?
Are the doors keyed alike? Do you have all the keys? Is the trim around the doors and windows finished inside and
out?
Is the insulation protruding out from the base, base trim, or any other areas?
Have all chalk and construction markings been removed?
Are there structural parts left over? Do you know where they belong?
B. Inside your building
First walk the perimeter of the inside of the building. Note that the columns are in good shape and are all bolted down.
Do the girts and flange braces seem to be in their appropriate places? All Nucor buildings will have some type of wind
bracing. Are the rods under tension or loose? Is the building properly insulated or can you see areas which appear to
be missing insulation? Check to see if light shows through at the eave, rake, or sill of the building; this is a dead give
away that there are still things to be finished off.
Next inspect the rafters and interior columns, if applicable. There should be no gaps between the connection plates
where the rafters meet the columns at the bolt locations. Check to ensure that the interior columns are in good shape.
Finally, your Nucor building structural components were coated at the factory with a red or grey primer. Please note
that this is for protection from the elements during shipment only and is not intended to be a finished coat. During some
seasons of the year muddy foot prints on the structural steel are unavoidable. Any cleaning of the product surface is
the responsibility of the Builder and should be considered "Dealer Prep". This is like the prep on a new car before you
take ownership.
C. Your Roof
Walk the perimeter of the roof. Are the gutters and downspout outlets in place as noted on the Nucor plans? Are they
free of debris and well drained? Are the fasteners all in place and well seated? Are the flashings in place at all
locations? Has the building been properly made watertight? Are all of the small openings sealed against the elements,
birds and rodents?
Walk the endlaps. Have the endlaps (classic, VR16 II or CFR) been installed per Nucor plans? Do the fasteners exhibit
penetration through the mastics? Are the fasteners all in place and well seated? Are the cinch straps of the CFR roof
properly installed and are the fasteners properly engaged? Are the stitch screws and structural screws of the classic
roof correctly installed?
Walk the ridge or high eave. Has the ridge cap or high eave been installed per Nucor plans? Do the fasteners exhibit
penetration through the mastics? Are the fasteners all in place and well seated? Is the ridge or high eave area free of
debris and well drained? Are the end dams or closures weathertight and properly installed?
Inspect other areas. Is there ponding around curbs or in any other areas? Does the roof drain properly? Is there any
“white or black rustâ€, dents or scratches on the panels and trim? Is the finish itself acceptable? Are the fasteners
throughout the entire roof in place and well seated? Do the mastics and caulks appear to be properly placed? Are there
any dissimilar materials coming into contact with Nucor material?

Preventive Maintenance Manual
II. ANNUAL MAINTENANCE
STRUCTURAL FRAMING
As a custom manufacturer, Nucor produces a wide array of structural framing systems including clear span rigid,
modular rigid, tapered beam, and lean-to. All are available in standard or wide bay options. Crane support systems and
mezzanines can also be included as part of the complete building package. Your Nucor building was designed to
achieve the optimal design solution for your building requirements.
A. Primary Structural Steel: Main Frames
Modifications to Shape
All structural steel designed, detailed and provided is an integral part of the building system order and must be
off-loaded, stored, and installed per the manufactures instruction. It is important to understand that any
omissions or modifications of materials as provided by the manufacturer can compromise the design integrity of
the structure. Any modification to the structural system must be reported to Nucor's Quality Services
Representative. For many reasons, no change can be made without the prior approval of Nucor. By making
field modifications without consulting Nucor, you may unknowingly void all warranties and cause the structure
to become unsafe. You may also assume the costs and liability associated with any corrective action taken.
Any party making such omissions or modifications without the consent of the manufacturer is taking design
liability for the building system.
Adding Loads
Collateral loads, unless specified in the Quote and Order Documents, are assumed to be uniformly distributed.
If suspended sprinkler systems, lighting, HVAC equipment, and the like, exceed 200 pounds, consult Nucor
Building Systems. Be particularly watchful for individual structural members that appear to be loaded
significantly more than others. The roof structure of your building has been designed to the specific load criteria
by your Builder, Architect, Engineer of Record, or retained design professional. Any changes or modifications
to your structure which add additional loads may adversely affect the buildings load capacity. Before hanging
any items from the buildings framing or adding any additional loads to the roof (sprinklers, piping, roof top units,
jib cranes, etc.), contact your Builder, Architect, Engineer of Record or competent licensed structural design
professional. Any additional loads placed on the structure or hung from the roof which deforms the purlins or
other structural components may seriously impair the structural integrity of the building and create dangerous
conditions. If your Builder is not available, contact your local District Sales Manager for additional service. To
locate your local Nucor representative please visit our website @ www.nucorbuildingsystems.com or call your
local Nucor plant for assistance.
Primer Coating
All structural members of the building system not fabricated of corrosion-resistant material or protected by a
corrosion-resistant coating are painted with one coat of shop primer. All surfaces to receive shop primer are
cleaned of loose rust, loose mill scale and other foreign matter by using, as a minimum, the hand tool cleaning
method prior to painting. This method is outlined in the Steel Structures Painting Council specification
SSPC_SP2. The Manufacturer is not normally required to power tool clean, sandblast, flame clean, or pickle.
Many manufacturers do not have the ability to do so. The coat of shop primer is intended to protect the steel
framing for only a short period of exposure to ordinary atmospheric conditions. The coat of shop primer does
not provide the uniformity of appearance or the durability and corrosion resistance of a field-applied finish coat
of paint over a shop primer. The Manufacturer is not responsible for the deterioration of the shop coat of primer
or corrosion that may result from exposure to atmospheric and environmental conditions, nor for the
compatibility of the primer used to any field-applied coating. Minor abrasions to the shop coat caused by
handling, loading, shipping, unloading, and erection are unavoidable. Touch-up of these minor abrasions is the
responsibility of the End Customer.
Primer Touch-up
Structural Steel normally requires no maintenance except in the event of oxidation. If the structural steel is
intended to be left in an un-painted state, clean the affected area and re-prime using the primer as supplied by
the manufacturer to spot treat or touch-up. To touch-up the primed members, a solvent-based primer must be
applied. Additional touch-up primer is available through your local Nucor Building Systems authorized Builder.

Preventive Maintenance Manual
In the event an authorized Builder is not available, contact the Components Department of Nucor Building
Systems for assistance.
If the structural steel is to have a topical finish coat of paint applied, clean the affected area and consult with a
qualified contractor for the use of proper primers and paints to achieve the desired results. Touch up priming,
Topical painting of the structural steel, and Compatibility of the factory applied shop coat to any field applied
coating is the responsibility of the end customer or any sub contractors retained by the end owner for such
work.
B. Secondary Structural Steel: Purlins & Girts
Modifications to Shape
All structural steel designed, detailed and provided is an integral part of the building system order and must be
off-loaded, stored, and installed per the manufactures instruction. It is important to understand that any
omissions or modifications of materials as provided by the manufacturer can compromise the design integrity of
the structure. Any modification to the structural system must be reported to Nucor's Quality Services
Representative. For many reasons, no change can be made without the prior approval of Nucor. By making
field modifications without consulting Nucor, you may unknowingly void all warranties and cause the structure
to become unsafe. You may also assume the costs and liability associated with any corrective action taken.

Preventive Maintenance Manual
Suspended Loads
Any load hung from the roof must be with the knowledge of Nucor. The method of attachment to a roof support
member varies with the type of load being suspended and supporting member. In no case should any part of a
purlin (roof zee) be deformed to accommodate a suspended load. Should you need to hang a suspended load,
contact your Nucor Builder, or Contractor who will coordinate with Nucor. No modifications to the structure or
addition of loads to the structure can be made without the knowledge of the project’s engineer of record and
Nucor.

Preventive Maintenance Manual
C. Crane Systems
Structural Bolts normally require no maintenance except in instances where the structure is exposed to
vibration, such as a structure with an overhead crane. In this instance, bolts are required to be inspected at
least once a year or per OSHA requirements. Crane Bracing is also required to be checked at least once a
year. Crane systems require constant maintenance. Follow the guidelines outlined by your crane system
manufacturer. For inspection and maintenance of cranes, refer to the applicable section of ANSI B30.11
chapter 11-2, ANSI B30.17 chapter 17-2, and CMAA Crane Operators Manual.
Crane Loads: Any building designed for crane loads was designed and provided as per the initial requests
indicated on your order documents. Any change to the building from the original design must be reviewed and
authorized by your Builder, Architect, Engineer of Record or competent licensed structural design professional.
If your Builder is not available, contact your local District Sales Manager for additional service. To locate your
local Nucor representative please visit our website @ www.nucorbuildingsystems.com or call your local Nucor
plant for assistance.
D. Wind Brace Rods
The bracing provided with your structure is of significant structural importance. All bracing which is in place
after the erection of the building should remain in place. Never allow removal of any bracing by any contractor
or maintenance personnel. If there are any questions regarding the removal or relocation of any bracing,
please contact your customer service representative for assistance. To locate your local Nucor representative
please visit our website @ www.nucorbuildingsystems.com or call your local Nucor plant for assistance.
Tension
Check annually to insure that all wind bracing members (cables or rods) are under tension. Consult Nucor
Building Systems for specific project related questions.
E. Building Evolution
Adding and Removing of Openings
Often adding a framed opening is as easy as cutting a hole in your sheeting and framing it in. At times, wind
bracing must be moved or opening locations affect column flange brace placement. By making field
modifications without consulting Nucor, you may unknowingly cause the structure to become unsafe. Always
consult Nucor Building Systems if you have a project-specific question.
Additions to your Nucor Building
Your Nucor Builder can assist you in developing an expansion of an existing Nucor building.
Nucor buildings can be designed with future expansion in mind.
Roof Panels, Wall Panels, Trims & Flashings
Proper and timely maintenance is an integral part of the long term success of a roof system in order for it to
remain water-tight. Proper maintenance is also required in order to preserve the integrity of the Galvalume®
protective coating of the steel sheets. Maintenance of the system is a requirement and responsibility of the
building owner. All roof & wall panels along with trims and flashings designed, detailed and provided by the
manufacturer are an integral part of the building system order and must be off-loaded, stored, and installed per
the manufactures instruction. It is important to understand that any omissions or modifications of materials
provided by the manufacturer, can compromise the water-tightness or protective coating integrity of the
materials. Any such omissions or modifications without the consent of the manufacturer can void product pass-
through warranties provided by the manufacturer.
General: Storage and installation of the wall & roofing system shall be in accordance with Nucor's printed
installation instructions. You should not store material on the surfaces of your panels, including roof areas of
your building. Roof and wall panels should not come in contact with or be marked with any graphite or lead
markers. Roof and wall panels should not come in contact with copper, lead flashing, exposed iron or debris.
The use of treated lumber in association with painted or unpainted Galvalume® steel sheets is a known
corrosive and will cause premature deterioration of the protective panel coating. Wall panels should be kept
clear of dirt & soil. Air conditioning condensation water should not be allowed to drain onto your roof or wall
panels and condensate lines should always be plumbed to the eave of the structure.

Due to a process of continual improvement, the information herein is subject to change without notice.
Preventive Maintenance Manual
Annual Routine Maintenance: At least once a year, check flashing and sheeting interfaces and lap joints in
the metal for proper seal and potential loose fasteners to ensure connection and water-tightness. Endlaps,
eaves, ridges, curbs, translucent panels, and other interfaces should be inspected and maintained yearly.
Normal adjustments or tightening of fasteners may be required. Should repair be required, please contact
either the original Builder or the manufacturer for proper methods and maintenance material requirements.
Panel end-lap maintenance and rebuilding instructions are available from the manufacturer. This includes the
removal of fasteners and mastics, proper cleaning, and reinstallation of mastics, hardware and fasteners. It is
important that this maintenance is completed according to the manufacturers recommended methods and
instruction to achieve water-tightness and prevent the nullification of material warranties.
Installation & Clean-up: During installation & Maintenance, the use of cutting tools that damage the painted
panel finish should not be used. When field-cutting or mitering roof & wall panels or trims and flashings, non-
abrasive cutting tools such as nibblers, shears, scissors or tin-snips should be used. Abrasive cutting tools
such as mechanical grinders, or saws can damage the Galvalume® or painted finish and create excess metal
shavings that can corrode the panels. The use of non-approved cutting devices may void your manufacturer’s
material warranty. Painted surfaces should be cleaned daily (whether during construction or maintenance work)
of all filings, cuttings, screws, pencil markings, and debris to prevent damage due to oxidation of foreign
materials. In addition to this, thoroughly clean all panels, trim, and gutters of all foreign material upon
completion of construction & maintenance.
Painted Finishes
WARNING: Always test cleaning procedures in a small inconspicuous area
before use on a large scale.
Routine Washing: (NOTICE: If located within a 1000 feet of a saltwater shoreline, roofing or siding
should be washed with potable water annually.) A 5% solution of commonly used commercial detergents
can be used on heavily soiled areas and will not harm your panel surface. Always rinse thoroughly with water.
Do NOT use wire brushes, steel wool, sandpaper, abrasives or similar cleaning tools which will mechanically
abrade the coating surface. Use a cloth, sponge or a soft bristle brush for application. For best results,
cleaning should be done in the shade or on a mild cloudy day.
WALLS
Cleaning
The following is the suggested maintenance for the upkeep of Nucor panels:
1. Dirt may cause apparent discoloration of the paint when panels have been exposed to dirt-laden
atmospheres for long periods of time. Chalking may cause some change in appearance in areas of strong
sunlight. A good cleaning will often restore the appearance of these buildings and an occasional light cleaning
will help maintain good appearance.
2. In many cases, simply washing the building with plain water using hoses or pressure sprays will be
adequate. In areas where heavy dirt deposits dull the surface, a solution of water and detergent (1/3 cup
laundry detergent per gallon of water for example) may be used. A soft bristle brush with a long handle may be
useful. A clean water rinse should follow.
3. Mildew may occur in areas subject to high humidity, but is not normally a problem due to the high inherent
mildew resistance of the baked finishes used. However, mildew can grow on dirt and spore deposits in some
cases. To remove mildew along with dirt, the following solution is recommended:
1/3 cup laundry detergent
2/3 cup tri-sodium phosphate
1 quart sodium hypochlorite 5% solution (chlorine-based bleach)
1 gallon water
Rinse with clean water immediately after use.

Preventive Maintenance Manual
Rust: Once a year inspect the panels for rust. Should any rust or rust stains be found, determine the source,
such as steel filings from drilling, sawing, grinding, etc. and remove them. The rust stain can generally be
cleaned off with one of the following: soap and water, mineral spirits, or a mild polishing compound as used on
a car finish. If you have any questions or concerns regarding rust on panel or trim surfaces, contact your local
Builder. If your Builder is not available, contact your Nucor Construction Services Representative for additional
service. To locate your local Nucor representative please visit our website @ www.nucorbuildingsystems.com
or call your local Nucor plant for assistance.
Paint Scratches: Scratches to the paint should be brush touched (artist brush) with touchup paint. If the
scratched area has not rusted, the paint may be applied without surface preparation. If the area is rusted,
remove the rust; prime the affected area and brush with color matched touchup paint. Some additional touchup
paint is available from your Nucor Building Systems authorized Builder or from Nucor Building Systems.
Non-Water Soluble Deposits On Zinc-Aluminum Finishes: Use mineral spirits (with a Neutral PH) to
remove non water soluble deposits (tar, grease, oil, paint, graffiti, etc.) from the panel surface. Do not use any
other harsh caustics or acidic compounds or cleaners that could potentially cause premature failure of the
coating and otherwise create permanent damage to the protective panel finish.
Non Water Soluble Deposits On Silicon-Polyester & Kynar paint finishes: Use a diluted mixture of the
common household commercial cleanser “Tide†& Water to remove non water soluble deposits (tar, grease, oil,
paint, graffiti, etc.) from the panel surface. Do not use any other harsh caustics, abrasives, or acidic
compounds or cleaners that could potentially cause premature failure of the coating and/or otherwise create
permanent damage to the protective panel finish. Solvents that may also be used to remove these items from
paint panel finishes include:
Alcohols - Not aesthetically detrimental when properly applied
Denatured Alcohol (Ethanol)
Isopropyl (Rubbing) Alcohol
Methanol (Wood Alcohol)-Note: Methanol is toxic
Petroleum Solvents - Not aesthetically detrimental when properly applied
VM & P Naphtha
Mineral Spirits
Turpentine (Wood or Gum Spirits)
Aromatic and Other - Use with caution:
Xylol (Xylene)
Toluol (Toluene)
Limit contact time to under 5 minutes maximum and test before using, exposure long enough to
damage paint finish will void your finish warranty.
DO NOT use acetone paint remover, Lacquer thinners, Esters, Ketones, Methyl Ethyl Ketone, or
Methyl Isobutyl Ketone on Kynar or Silicon-Polyester paint surfaces. Contact and exposure with
these products can result in blemishes detrimental to the aesthetics of your metal building and will void
your warranty
Most organic solvents are flammable and/or toxic and must be handled accordingly. Keep away from
open flames, sparks and electric motors. Use adequate ventilation, protective clothing and goggles. A
fresh water rinse should be used after application of alchohols, solvents, or aromatics to ensure that all
residue is removed.
Cutting/Drilling
Field cutting and drilling of panels and trim is a normal process during the life of a metal building. The use of
improper tools or cutting techniques can result in an unfavorable appearance of the finished product, and may
void your warranty from the manufacturer.
Some of the most common activities that require field cutting of panels and trim are:
• Replacing damaged panels • Adding holes at pipes, etc.
• Mounting external fixtures

Preventive Maintenance Manual
Drilling
It is important that any and all shavings from drill bits and self-drilling screws be wiped off of the siding and roof
panels. The byproducts of the drilling process are actually hot metal shavings. These shavings can embed
themselves into the finished coat of the material, resulting in rust.
Panel warranties do not cover this type of damage.
Cutting
Full width panels should always be cut with a shear or power nibblers. The hot metal shavings produced by a
grinder or hot saw will burn through the panel causing the primer to evaporate into ashes. This is one of the
most common reasons for rust. This rust may appear immediately or may not appear for months, and is not
covered under the panel warranty. By using a shear or nibblers, this hazard can be avoided.
Figure 1 1. Hot sparks caused from cutting the panel burns through the primer.
2. The primer under the finish coat on the opposite side is also burned.
Figure 2 3. In time, the finish coat collapses causing black steel to be exposed.
4. As a result, red rust appears on the panel.
Painting
It is likely that during the life of your metal building the exterior panels will require touch-up paint. Sherwin
Williams’s Industrial Coatings Division can match and supply the correct primer and finish paint. Please note
that all atmospheric conditions have some effect on the panel finish; give this due consideration. Consult your
Quote and Order Documents or contact Nucor Building Systems for the correct type of paint supplied on your
particular project. Touch-up of these areas are the responsibility of the End Customer.
ROOF Systems
General
Galvalume® and its chemical make-up is designed to withstand minor cuts and abrasions. The unique
aluminum/zinc coating on the steel will virtually "heal" those minor abrasions that occur. That same “healingâ€
property that protects the panel also causes the Galvalume® coating to be highly reactive when in contact with
some types of foreign debris such as copper wires, drill shavings and the like. When left on the roof, these
materials can cause the panel to rust. The Galvalume® roof must be kept free of debris in order to reach the
expected service life.
The Nucor "CFR"TM, VR16 IITM or "Classic "TM Galvalume® roof will give you years of productive life if properly
installed and maintained. However, a regularly scheduled program of preventative maintenance is required in
order for the roof to function. A reasonable schedule of maintenance begins with proper inspection during
construction and a follow-up plan within 60 days after occupancy. Your roof should be maintained annually
thereafter. A reasonable estimate of the cost of maintenance is approximately $0.01 per square foot of roof per
year.
"CFR"TM Roof System
Larger “CFRâ€TM roofs are designed to "float" or move as the temperature of the roof changes. This action of
floating allows the roof to expand and contract with normal temperature changes. This is a unique feature of
standing seam roofs on the market today. Since the roof moves, it must not be restrained in any way. Flashings
at the ends of buildings must be allowed to float in concert with the roof. Before adding additional fasteners or
flashings to the building ends, be sure to contact your Nucor Builder for specific instructions.

Preventive Maintenance Manual
“VR16 IIâ€TM Roof System
The “VR16 IIâ€TM Roof System is a vertical rib panel that is perfect for architectural requirements. This is a
weathertight roof system that is ideal for hips and valleys. The panels are installed with concealed fastener
clips allowing for thermal movement. It is mechanically seamed for weathertightness.
"Classic"TM Roof System
Smaller projects can often utilize the "Classic Roof"TM system. This roof is attached directly to the roof
secondary members and does not allow the roof system movement as "CFR"TM does. While the cost of the roof
system and labor required to install this type of roof system is less, the need for routine maintenance is no less
important.
Inspection
During erection your roof is subjected to construction traffic. This is normal and should be minimal provided the
contractor uses good judgment. It is recommended that the owner take the following steps before the erector
leaves the jobsite. These same steps should be followed on your annual visit.
Keep a log of your maintenance work. This will help you set a good schedule as well as document what steps
were taken, and when. Periodic roof maintenance should start with a walk through the building interior to
observe if modifications have been made to the primary or secondary support members. Make sure hangers
for heaters or sprinklers do not extend above the structural or touch the standing seam roof. Make sure fire
walls that extend to the roof do not restrict the panel movement or create ponding.
Safety First / The Building Exterior
Walk the exterior edge of the building at ground level and repair any downspouts that have clogged or been
dislodged in any way. Once on the roof, make sure you are aware of any potential safety issues such as steam
or hot water vents, electrical lines, translucent panels and the like, and take the necessary precautions to
prevent an accident. Be sure to follow all state and local safety requirements as well as rules of good common
sense. Beware of the potential for nests of wasps or bees on the roof.
Walking the Eaves
Walk the eaves of the building, taking care not to get too close to the edges. Make sure all gutters and
downspouts are clean and free of debris. Look for any irregularities, including missing fasteners, overlapping
cinch straps, and stripped or broken fasteners.
Any fastener that was not seated properly will work itself out eventually. Replace any unseated or loose
fastener with the next larger fastener size.

Preventive Maintenance Manual
Fasteners: The fasteners provided with your structure are important to the long term success of your panel
finishes and the design integrity of the system. Do not locally obtain or substitute fasteners on a project, unless
otherwise authorized by the manufacturer. Replacement fasteners can be obtained through your local Nucor
Building Systems authorized Builder. If your Builder is not available, please contact our Components
Representative for assistance.
"CFR" TM Panel Endlaps
The CFR panel endlaps should be checked for any unseated fasteners or back-up plates that may not be
properly engaged. An endlap in which the back-up plate is properly engaged will feel firm underfoot. This
indicates that the cinch strap is joined to the back-up plate.
Trouble Shooting
Should you find an improperly installed back-up plate on your CFR roof, remove the cinch strap, pry
the endlap apart, and clean any mastic from the panels. Affix the back-up plate in the proper position
with the back-up plate tabs and apply gun grade caulk between the panels. Make sure the caulk
covers the endlap completely, especially in the areas around the fastener holes. Thread an awl
through the cinch strap, panels and back-up plate as indicated in the Erection Manual. Replace
fasteners using the next larger size or the “goof†screw as supplied by Nucor.
“VR16 IIâ€TM Panel Endlaps
The VR16 II panel endlaps should be for any unseated fasteners or back-up plates that may not be properly
engaged. An endlap in which the back-up plate is properly engaged will feel firm underfoot.
"Classic Roof" TM Panel Endlaps
The endlaps on the Classic Roof are located over a purlin and are connected with screws – Check for any
screws that are stripped or washers that are not seated along the endlap, ridge, rakes and eaves. Stripped
screws must be replaced with an oversized fastener.
Ridge Areas
Walk the area adjacent to the ridge, being careful not to step directly on the cap. The ridge should be free of
pending water and debris. Check for and remove any debris in the area. Check for any fastener that may not
have been seated well. Review interface between the ridge and the rake flash or any parapet condition. Inspect
the rake flash and check for any area where the flash is not seated to the panel.
Single Slope Buildings
Don't forget to walk the high side of a single slope building. Check for tightness of flashings and fasteners.
Verify that the seal between the flashing and the end dam is in place. Five fasteners are required to make the
trim to end dam connection on a CFR roof.
Expansion Joints
Larger buildings have longitudinal and transverse expansion joints. During your walk through, make sure to
look for any irregularity in a flashing joint or for any loose fasteners.
Step-down or Parapet Conditions
Be sure to check step-down (high/low) conditions or areas where blowing rain and snow severely test the
design and installation of your building. Flashings must be allowed to "float" on the CFR roof, yet prevent
moisture from entering the building. When maintaining the roof, be sure to look for any loose fasteners or
mastics. Remove any debris from step-down areas. Be careful of the addition of any fastener that will restrict
movement of the roof. A restrained roof may cause maintenance problems in a system-related area. Consult
your Nucor builder and the Nucor Erection Manual for specifics.
Roof Curbs and Hatches
Look around all roof hatches and curbs for debris left by erectors or repair men. All debris must be removed
from the roof. Check for seated fasteners and ponding water. Water must flow freely around all curbs. Never
use tar or apply topical mastics to the surface of the panels. Topically applied sealants will only conceal the
cause of a problem. You may want to consider some type of permanent work platform around those units that
13

Due to a process of continual improvement, the information herein is subject to change without notice.
Preventive Maintenance Manual
require constant maintenance. Condensate lines from air conditioner units expel water contaminated with lead
or copper. This must not be allowed to come in contact with the roof panel. The copper and lead are very
reactive with the steel panels and can cause rust. This water must be piped off the roof to the building exterior.
Corrosive Materials: Graphite, lead, copper, treated lumber, lead flashing, exposed iron, salt, chlorine, &
miscellaneous debris including dirts & oils are all commonly known corrosives to the protective Galvalume®
coating and can cause premature deterioration of panel finishes. These materials specifically, but not limited to
other contaminants, can be severely detrimental to the integrity of the coatings provided. Failure to keep
building contaminants from contact with your panel surfaces can void panel warranties.
Dissimilar Materials
Iron pipes for gas lines, structural steel framing for roof units, and similar installations must be painted to
prevent rusting. Water run-off from rusted iron or steel will diminish the life of the panel and should be piped off
of the roof. Lead or copper can not be used on the roof for any reason. Never use a pencil to mark information
on the roof. The graphite used in pencil leads is not compatible with Galvalume® and will quickly destroy the
protective coating.
Debris: At least once a year, clean the roof & gutters of leaves or other debris which can trap or pond water on
the roof. Wash dirt & debris from the panel surface. Local conditions govern the frequency of necessary routine
maintenance. It is the responsibility of the owner to keep the roof free and clean of debris and corrosive
materials at all times.
Penetrations
Penetrations are pipes, curbs, and other items that penetrate a metal roof panel. Penetrations must be flashed
properly to assure a watertight roof assembly. When inspecting the roof, you should see that pipe flashings
have a weathertight seal at the panel surface. Ensure that the penetrations are secure and not prone to
movement. Penetrations should not impede the flow of water. Curbs should be properly flashed, especially at
the corners; skylight domes or panels should be checked for deterioration. As with any inspection, you should
check for missing or loose fasteners, as well as possible corrosion of the metal panels.
Pipes, Supports, & Condensate Lines: Pipes, conduits, and supports for roof-supported units shall be of a
non-corrosive or rust free material. Field painting of pipes and supports may be required to resist corrosion.
Condensation from roof-top units shall be piped to interior or exterior locations. Damage due to condensate
water is not covered under manufacturer’s warranty.
The Roof in General
Observe all panel side laps to make sure the erector properly seamed each side lap. Also review the panel
surface for pitted, worn, stained or rusted areas. If there are areas of concern found on the roof panels, contact
Nucor Construction Services. Remove all debris from the roof at least once a year. Make sure all workmen who
enter the roof know to remove their trash and debris. This will simplify the maintenance process.
Sealants & Mastics (gray or white tapes) are designed to be used as gaskets. In order for them to perform
properly, clamping action is established by using fasteners at predetermined locations. Proper location of
fasteners and mastics will assure that seals perform as designed. See the Erection Manual for specific
locations. Mastics are effective only when applied between two pieces of metal and are not to be used
topically.
Sealant Removal: Precautions should be taken to prevent sealants from getting on the painted surface, as
they may be difficult to remove. Sealants should be removed promptly with a solvent such as alcohol or a
naphtha type of solvent. Caution: It may be possible for solvents to extract materials from sealants that could
stain the painted surface or could prove harmful to the sealants. Test a small inconspicuous area first, before
wide spread use.
Butyl Caulking is applied between panel seams or joints as directed by the Erection Manual. Butyl caulk is a
non-skinning caulk that is effective when used between pieces of metal. It is not to be used topically.
Polyurethane Caulking is a skinning caulk applied between trim laps or joints as directed by the Erection
Manual. This caulk is typically uses in areas that may be exposed to the eliments.

Preventive Maintenance Manual
Topical Coatings: The use of tar and other topical applied products should not be permitted or utilized as a
method of leak repair. The use of topical coatings will void panel warranties and is detrimental to the
performance of the materials. The use of any topical coating or other topical applied product is prohibited,
unless specified by the manufacturer.
Crimping or Seaming: Nucor CFRâ„¢ & VR16 II"â„¢ roof hand crimpers & electric seaming machines are
specially designed for use with Nucor roof products. Under no circumstances shall the Nucor crimper or electric
seaming machine be used on any other manufacturer’s roof system. In addition, under no circumstances is
another manufacturer’s crimper or electric seaming machine be used on a Nucor CFR™ or VR16 II"™ roof
(even if they appear to be the same). Permanent damage to the seam and/or the panel finish may occur if the
Nucor crimping tool is not used and shall void all warranties.
Ice & Snow Buildup: You should be familiar with the roof load specified for your building regarding snow & live
loads. Any significant accumulation of snow and ice may threaten the structural integrity of your roof if it
approaches or exceeds the design roof capacity. In the event of severe winter storms, the accumulation of
snow and ice should be carefully monitored and frequent inspections made to detect any deflection of the roof
system, damming or clogging of gutter systems, ponding or unusual drifting conditions.
Excessive ice & snow should be removed from roof areas. Please refer to our Snow Removal Guidelines for
additional information specific to the proper removal of snow & ice. The removal of snow & ice should be
performed by experienced personnel according to the Snow Removal Guidelines provided, in order to avoid
damage to the roof or the structure. Appropriate precautions should be taken to minimize the risk of injury on
the roof during hazardous conditions. Excessive ice & snow removal is particularly important in gutter areas
(eaves & valleys) and in areas of the roof sheltered from the wind (behind facades, stepped roof conditions,
etc.).
If any evidence of structural distress is noticed, contact the building manufacturer, your Builder, or consult with
a competent licensed structural engineer or professional for assistance in avoiding damage or catastrophic
failure of the roof system.
Foot Traffic: Roof traffic is a leading cause of roof leaks. If routine traffic is unavoidable, have your builder
install a walkway designed for use with your roof panel. When walking on the roof is required:
• Avoid stepping on the ridge caps.
• Avoid stepping on lap joints in roof panels and flashings.
• Avoid walking near roof curbs or other roof penetrations.
• Avoid stepping on panel ribs between purlins.
• Do NOT step in or on gutters or the gutter hanger system.
• Do NOT step on or near translucent panel skylights. !!! CAUTION !!! If skylights are present in your roof, extreme
care should be exercised when working in those areas. NEVER STEP DIRECTLY ON A SKYLIGHT, OR IN THE
SURROUNDING AREA ADJACENT TO A SKYLIGHT. Skylights may not support the weight of a worker, and
bodily harm could result from a fall. Please follow all OSHA and/or other state and local safety guidelines
applicable for the particular jurisdiction.
Gutter and Downspouts: Clear all debris (leaves, dirt, etc.) from gutters and downspouts as required
periodically and kept free-flowing at all times. The frequency required is dependent on the building’s
surroundings.
Foliage: While bushes and trees enhance the appearance of any building, their contact with the panel systems
can produce scratches in the paint surface which can eventually cause problems. Keep bushes and trees
trimmed back from the panel surfaces.
Damaged Trim: Trims located around openings (corner trims, base trims, jamb trims, etc.) can sometimes get
damaged by vehicle traffic and can lead to water-tightness issues. Replacement trim can be obtained through
your local Nucor Building Systems authorized Builder. If your Builder is not available, contact your local Nucor
Components Representative for additional service. To locate your local Nucor representative please visit our
website @ www.nucorbuildingsystems.com or call your local Nucor plant for assistance.

Preventive Maintenance Manual
Accessories
General: Windows, doors, vents, and louvers should be checked yearly for loose fasteners and any moving
parts should be lubricated as necessary.
Gravity Vents / Roof Vents: Gravity roof vents are designed to allow inside air to be vented to the outside.
The throat and dampers also can allow blowing rain and snow to enter the inside of the building. Inspect vents
annually for debris, bird intrusions, etc. Inspect pull chains and lubricate mechanisms as required. Hard to
operate roof vents are usually the result of pulleys and damper rods in need of lubrication or the chains and
cords not being on track. Check operating hardware and lubricate as needed.
Roof Curbs: Heavy vibration from a mechanical unit can cause water leakage around a roof curb. Should this
occur, check the sealant and fasteners around the curb. Any loose fasteners should be tightened or replaced
with the next larger size. Any sealant or mastic that has deteriorated should be removed and replaced with
new. If possible, isolate the unit from the curb to minimize vibration to the curb. Look around all roof hatches
and curbs. Debris from the mechanical repairmen must be removed from the roof. Check for seated fasteners
and ponding water. Water must flow freely around all curbs. Never use tar or topically applied mastics on the
surface of the panels. Topically applied sealants will only conceal the cause of a problem. You may want to
consider some type of permanent work platform around those units that require constant maintenance.
Condensate lines from air conditioner units expel water contaminated with lead or copper. This must not be
allowed to come in contact with the roof panel. These must be piped to the building exterior.
Iron pipes for gas lines and the like, structural steel framing for roof units, etc. must be painted to prevent
rusting. Water run-off from rusted iron or steel will diminish the life of the panel. Lead or copper can not be
used on the roof for any reason.
Dektites: Inspect Dektites annually. Water should not be allowed to pond on the Dektite. Remove any algae
growth found on the Dektite.
Louvers: The operating hardware within a louver occasionally needs to be cleaned and a new light coat of oil
or grease applied. This will improve the ease of operation.
Translucent panels: Inspect translucent panels annually for loose fasteners, missing mastic, etc. Translucent
panels may be cleaned with a mild nonabrasive cleanser. Avoid using any cleanser that may cause hazing. Do
not step or stand on the panel itself at anytime. Do not remove warning stickers. Never paint over a translucent
panel.
Doors:
Overhead Doors: Periodically check the attachment bolts around an overhead door and tighten as required.
Call the door manufacturer or consult the door supplier should the door get out of alignment or the mechanical
parts within the door become hard to operate.
Sliding Door: Periodically clean the sliding door tracks and lubricate the rollers to help assure ease of use.
Call the door manufacturer or consult the door supplier should the door get out of alignment or the mechanical
parts within the door become hard to operate.
Walk Doors: Walk doors should be checked periodically to assure tightness of locksets, closure hardware and
door hinges. Any loose fasteners should be tightened. Any moving parts that start to stick or squeak should
be properly lubricated.
The following is intended to serve as a general guideline for maintenance activities required for hollow metal
doors and frames. Maintenance will be for the most part associated with the accessories and hardware
attached to the door and frame.
Maintenance of any product is important and necessary to obtain the maximum benefits of product service and
longevity. Hollow metal doors and frame assemblies are no exception. In fact, in some cases where the door
and frame assembly are used as a "fire rated" fire barrier or a "leakage rated" smoke and draft barrier, proper
maintenance is crucial. Basic maintenance is imperative and well worth the effort to provide for life safety.

Preventive Maintenance Manual
Areas of inspection: The following items should be periodically checked. Since doors in different
areas of a building experience different levels of traffic, the frequency of periodic inspections would
occur with consideration of this.
Hinges: Check all hinges for loose screws, hinge pin wear, or other notable defects. Service the
hinges or remove the defective parts and replace if necessary per the manufacturer's recommendation.
The door should always swing freely and smoothly from open to latched (when latching device is used)
position without obstruction.
Locksets, Panic Devices, Fire Exit Hardware: Check all locksets for loose screws, linkage arm wear,
fluid leakage, hinge pin wear, or other notable defects. Service the lockset or remove defective parts
and replace per the manufacturer's recommendation. The door should always latch freely and
smoothly without obstruction. Self-latching should always function freely and smoothly as the door
swings into the closed position. Additional force should not be needed to achieve latching. Worn or
defective hardware should be repaired or replaced by a qualified technician.
Strike Plate: The strike plate should be adjusted to seat the door leaf firmly against the jamb. The
plate should also be firmly attached to the frame or inactive leaf of a pair of doors. Check for loose
screws and/or other notable defects. Service or remove strike plate if necessary.
Weather Stripping: Weather stripping should be adjusted to prevent air from leaking excessively
around the door. Weather stripping should be cleaned periodically to assure a proper seal. Worn or
damaged weather stripping should be replaced as required.
Closing Devices: Check all closing devices for loose screws, linkage arm and pin wear, fluid leakage,
or other notable defects. Service the device or remove defective parts and replace as needed. The
primary and secondary closing speed adjustments should also be set and maintained in accordance
with the manufacturer's recommendations. The device should allow the door to operate freely and
smoothly throughout its entire swing and positively latch (if so equipped) or remain in the closed
position.
Surface Bolts/Flush bolts: Check all surface bolts or flush bolts for loose screws, rod bolt adjustment,
and strike plate (on both door and frame if so equipped) attachment. Service the device or remove
defective parts and replace as needed. The rod bolts should retract, extend, and engage the strike or
keeper hole freely and smoothly for both manually and/or automatic flush bolts.
Glass Lites: The glazing material should be checked for cracks and/or missing pieces of glazing. The
glazing mounting frame should be checked to assure screws (if used) are tight and the unit is securely
attached to the door. Service the glass lite or remove defective parts and replace as needed. Also be
sure to use approved safety glass in appropriate applications/ locations, or fire rated glass and glazing
in fire doors, windows or lites.
Door and Frame Finish: A general visual inspection of the door and frame finish is appropriate. Any
excessive finish defects should be repaired and repainted. Adequate protection is needed to prevent
the product from rusting and shortening its service life.
Windows: Caulking in windows will deteriorate in time, usually resulting in window leakage. If this happens
remove the old caulk and apply new caulk in its place. Windows that become hard to slide should have the
track area thoroughly cleaned and a light coat of lubricant applied to the tracks.
The following is intended to serve as a general guide line of maintenance activities required for aluminum
windows and frames. Maintenance will be for the most part associated with the accessories and hardware

HVAC / CLIMATE CONTROL SYSTEMS / INSULATION
CONDENSATION
Note: This publication has been prepared to assist the Owner in understanding and dealing with condensation.
Its contents are based on information believed to be reliable. However, the prevention and elimination of
condensation depend on the total design and construction of the building, which is beyond the responsibility of
Nucor: Accordingly, information herein should not be regarded as a recommendation concerning metal building
design and construction.
Construction is fast paced. In our business, we provide sheltered space. Without careful thought to the
mechanical systems, the insulation system, and our methods of construction, the presence of condensation
becomes a possibility. The effects of condensation can be devastating.
Dew Point: The air we breathe is filled with many gases including water vapor. The amount of water the air
can hold is proportional to the temperature. "Dew point" is described as the temperature at which air can no
longer hold water vapor. That is the temperature when condensation occurs. Condensation will occur on any
surface that is at or below the dew point temperature.
During Construction: Huge amounts of moisture can be introduced into the air during the construction stage.
Excavated earth can introduce large amounts of water to the air. Often, the contractor will fully erect the
framing, roof, walls, and insulation so it becomes easier to pour concrete inside. Heat may also be added to
keep the concrete warm.
Under these circumstances, the interior of the building is literally flooded with moisture. As the air becomes
saturated, condensation may occur on the steel, the insulation, or any other surface. The result is often
disastrous.
What Can Happen?: If condensation collects on the interior of the building, rust literally covers the frames and
purlins. Sometimes the insulation becomes saturated, convincing the owner that the roof is defective. In colder
conditions, ice forms on any surface where moist air comes in contact with a thermal break. Ice may form on
purlins, door knobs, window cranks, or even the seams in the insulation. To prevent this, the moisture in the
18

Preventive Maintenance Manual
building must be removed with the use of fans or other means. By replacing moist, inside air with less humid
outside air, the conditions inside become more balanced and condensation can be prevented.
The Construction Stage: During construction, proper planning is essential for the control of condensation.
Ventilation of the slab and foundation work is critical. Proper installation and design of the vapor barrier is also
important. Remember, ample consideration to each area of construction is important to the success of the
project.
Proper Design and Planning: Careful planning with regards to mechanical systems, methods of construction,
insulation systems, and end use will insure that the owner's expectations are met.
Roof Section: The warm, moist air inside a building must be kept at a relative humidity level below the dew
point. A vapor barrier alone cannot prevent condensation. The insulation design of the building, along with the
construction techniques and the design of the air handling systems, work together to prevent damage due to
condensation.
At some point in the range between indoor temperature and outdoor temperature the dew point is reached. The
vapor barrier helps prevent warm, moist, inside air from condensing on the insulation.
Insulation
**Inspect the exterior of your building for exposed insulation and call your contractor immediately if
found. Exposed insulation will wick and hold water against the ends and back side of the panels,
causing rust to occur.
Insulation Facings: Insulation facings should be monitored continuously and a thorough inspection made
once a year. Any holes or tears in the facing should be repaired with patch tape as supplied by the insulation
supplier. Remember, even a perfectly installed barrier is not a perfect vapor barrier.
Condensation: If your building is experiencing excessive condensation, consult your HVAC contractor to
assure that humidity levels and air movement are as projected. Also, have your building contractor check to
make sure there are no obvious openings in the insulation splices. The unfaced surface of your insulation
should always be in full contact with the exterior steel sheets.
Loose Insulation: Insulation tearing loose at various locations within the building (particularly at the eave or
base) might not be the result of poor insulation, but rather a strong negative pressure inside the building
resulting from improperly balanced HVAC system or an extra exhaust fan added after the erection of the
structure. This, combined with a strong wind outside the building will often result in the insulation coming loose
in these areas. The unfaced surface of your insulation should always be in full contact with the exterior steel
sheets.

Preventive Maintenance Manual
Roof Leaks: Should you observe evidence of a roof leak, such as water on the floor, stained ceiling tiles or a
bubble in the insulation vapor barrier, contact your building contractor immediately. After the leak has been
repaired, have your contractor cut the vapor barrier where the water has collected to allow the wet insulation to
drain. Once the insulation has thoroughly dried, repair the vapor barrier with patch tape available from the
insulation supplier. There are various reasons a roof leak might occur, such as:
• Improper Installation
• A lack of routine maintenance
• Damage to a component
• Deterioration of a component
• Insulation air space void that creates condensation
It is also possible that a leak might not be the result of the above referenced conditions, but rather the result of
a strong negative pressure inside the building from an improperly balanced HVAC system. If you have any
questions or concerns regarding specific roof leaks on your building, contact your local Builder. If your Builder
is not available, contact your Nucor Construction Services Representative for additional service. To locate your
local Nucor representative please visit our website @ www.nucorbuildingsystems.com or call your local Nucor
plant for assistance.
NEGATIVE PRESSURE
Negative air pressure is force that can compromise sealants and affect the weathertightness of a building
system. If sealants become compromised then it is entirely possible for a leak to develop over time. If a leak is
left unaddressed, it can lead to potential water-infiltration into the insulation cavity. Over time this can create a
wide range of issues from annoying leaks, to mold & mildew, to sagging insulation, and to potential premature
corrosion of the panels, trims and structural’s in the affected area. The phenomenon of negative air pressure is
basically a condition of unbalanced air pressure between the inside air pressure and outside air pressure of the
structure. When a condition exists with too much outgoing or exhausting air combined with a lack of incoming
air, then a vacuum is created. When the vacuum is created, it naturally wants to pull outside air into the
structure. When the pressures are high enough, they also begin to pull any potential standing water into the
structure as well. In order to restore the balance and equalize the pressure, additional incoming air supply is
required. This is typically accomplished with the addition of Make Up Air units added to the structure. Proper
measuring and evaluation of needed Make Up Air supply requirements is typically provided by a qualified
mechanical engineer or contractor. Negative pressure can be a concern and primary source for water-
penetrations. The building owner should have a qualified mechanical engineer or contractor retained for proper
testing of existing conditions to address the negative pressure. If Negative Pressure is evident on a project,
then it needs to be addressed in full before attempting to address any additional pursuant leaks.

Preventive Maintenance Manual
Snow Removal
Roof snow accumulations in excess of specified project design loading criteria can cause significant distress to your
building structural system. Snow will build up in areas around firewalls, parapet walls, valleys, dormers, and on lower
roof levels where a roof step occurs. Since the density of snow varies depending on weather conditions during and
after a snow fall, it is not possible to determine a single value for the allowable height of snow that a building can safely
support.
The underlying snow density increases due to melting from the building heat loss and as water is absorbed from the
melting snow above. As weather and temperature changes continue, ice may build up under the snow layers, further
increasing the building roof loading intensity. This ice build up also causes additional water back-up on the roof deck.
The most severe condition occurs when rain falls on a roof system already loaded by snow. In this case, the snow
absorbs the rain water, and loads can approach the weight of water (62.4 pounds per cubic foot, or 5.2 pounds per inch
of depth). This condition must be monitored with extreme caution.
The following procedure may be used as a guideline for responding to roof overload conditions due to extreme snow
and ice build up conditions:
Snow Removal:
(1) Visually inspect the roof system to identify unusual deflections of frames, purlins, or joists. Starting in this area,
remove approximately one-half of the snow depth in a pattern that does not cause an unbalanced loading condition on
the frames or purlins.
(2) In general, the shoveling pattern should progress from each endwall of the building towards the center. On larger
roof areas, additional people working from the center of the building to the ends is recommended.
(3) Along the building width, remove snow from the eave towards the ridge, sliding the snow off the roof over the gutter.
On gabled buildings, remove the snow on both sides of the ridge at the same time.
(4) Remove the remaining half of the snow depth in the same manner as described above.
(5) Never use metal shovels or “scrape†the roof down to the surface of the panel. Remember, the objective is to
relieve the excess loading condition due to the weight of the snow, not to completely clear the roof panel of all snow
and ice. Attempting to scrape the roof will result in broken fasteners and loose cinch straps, creating roof leaks.
(6) Keep gutters, downspouts and roof drains open and free flowing to prevent water back up and ice build up on the
roof system. Ice damming conditions are especially likely on the north side of a building and in shaded areas. Installing
heat tape in gutters and downspouts can also be used as a precaution, however, heat tapes may not be 100% effective
in extremely low temperatures and should be checked regularly.
(7) Watch for extreme deflections and listen for unusual noises when snow and ice build up conditions exist.
Safety Guidelines:
(1) Always provide proper safety precautions when working on the roof.
(2) Pay special attention to and be aware of Translucent Roof Panel locations. These panels are not intended to
support roof foot traffic loads.
(3) Be cautious of snow or ice breaking away and sliding down the roof, even on low slope buildings. Metal roof
systems are extremely slippery when wet. It may be necessary to locate ladders at the end of the building to avoid
sliding snow.
(4) Use extreme care when working along the edge of the roof.
(5) Never send one person alone on a roof to remove snow.
Nucor does not make any recommendation on when to remove snow from roofs. It is up to the individual property
owner to consider the benefits and dangers of snow removal and decide their own course of action. Remember to
consider the depth and relative moisture content of your snow and the capacity of your roof structure in making your
decision to remove snow or not.
For additional information, it is also recommended to review the “Snow Removal†section of the Metal Building Systems
Manual, current version.
Additional suggested information regarding maintenance is also in sections titled ‘Gutter & Downspout Maintenance’ &
‘Ice Damming’.
Also refer to the ICBEST – 2001 article ‘Minimizing The Adverse Effects of Snow and Ice on Roofs’.

Preventative Maintenance Manual
III. The Annual Inspection Report
The best preventative maintenance that one can do is to perform scheduled annual inspections to identify and
solve problems as they occur. This will help to optimize the service life of the building, keep the building
aesthetically pleasing, functional, and virtually weather tight to protect your products, your facilities, and your
personnel. This inspection will require a critical examination of both the interior and exterior components of
existing assemblies, cladding, doors, windows, cranes, and flashings. Keeping a log of your maintenance work
will help you maintain a good schedule as well as document what steps were taken, and when. Any preventive or
corrective maintenance procedures should be designed to keep the building in a virtually weatherproof condition.
Any modifications found to the structural systems during your inspection must be reported to Nucor’s Quality
Services Representative. By making field modifications before consulting Nucor, you may unknowingly void all
warranties and cause the structure to become unsafe. You have also assumed all costs involved in the process.
If a manufacturer’s or contractor’s warranty is obtained for a roof assembly, one of the most important things a
building owner can do is read and understand the terms and conditions of all warranties. The manufacturer’s or
contractor’s warranty is a legal contract, and the warranty, for a variety of reasons, can be voided like any other
contract. These reasons may include but are not limited to the following:
. • Neglect by not performing inspections, repairs and routine maintenance in a timely manner.
. • Failure by a building owner to notify the warrantor of leaks in the roof assembly.
• Failure by an owner to notify the warrantor before installing new rooftop equipment and penetrations or making
any other modifications to the building system.
• Failure to have permanent repairs or maintenance performed in accordance with the warrantor instructions, such
as:
• Using material not manufactured or approved by the warrantor or using an incompatible material for a
repair.
• Work performed by a contractor not approved or authorized by the roof assembly manufacturer or
warrantor.
• A change in the use of the building unless approved by the warrantor.
• A change in ownership of the building; many warranties are nontransferable.
Building owners should maintain historical records of these inspections. A historical record should also be kept to
provide the owner with data concerning the original erection of the building, whom the erector was, the contractor,
building manufacturer, warranty information, any special conditions, or any known contaminants that may be
discharged onto the building surfaces. An owner should also use the historical record to document all subsequent
inspections, maintenance and repairs performed on the building.
Before the inspection takes place, please refresh your knowledge by reading through the Preventive Maintenance
Manual. The manual is a good reference and will go into more detail and explanation to help you complete a
thorough inspection.
As always, apply all safety precautions and requirements as mandated by state and local requirements as well as
rules of good common sense while during your inspections.
After each annual inspection, a copy of your report is to be sent to the appropriate original provider divisions

IV. Nucor Warranties
Warranty
A warranty is a covenant of the law in which the seller of a product gives assurance of and binds themselves to
conditionally defend the product. A warranty is not a one-sided agreement. Product warranties offered by Nucor are a
pass through of the warranty issued by a mill or coil manufacturer to Nucor. They cover raw material supplied by a mill
and the manufacture of building materials by Nucor. System warranties (weather-tightness warranties) are provided by
Nucor based on proper installation of the complete product system.
The product warranties offered by Nucor cover building materials only. Labor to disassemble, remove, and reinstall are
not covered by these warranties. In the event of a claim, it is the Builder’s responsibility to notify Nucor, make an initial
inspection, and to make a sample of the product available to Nucor and the appropriate mill for study.
The warranties issued by Nucor contain the conditions by which the product must be manufactured, stored, installed, and
maintained. If these guidelines are not met, it could render the warranty with Nucor and the mill void.
The Builder’s responsibilities are outlined in the Warranty Instructions Guide. This guide defines the types of warranties
offered by Nucor and the Builder’s role in servicing the process. The Warranty Instruction Guide is included in the Builder
Kit, or the Builder can purchase it from our Marketing Department. The warranties offered by Nucor are:
Standard Warranties:
25 Year Galvalume® Roof Warranty
25 Year Wall and Roof Paint Warranty for Silicon-Polyester
30 Year Wall and Roof Paint Warranty for Kynar
One Year Building Warranty
Extended Warranties:
20 Year Weather-tightness Warranty for “CFRâ€â„¢ Roof
20 Year Weather-tightness Warranty for Composite “CFRâ€â„¢ Roof
20 Year Weather-tightness Warranty for “VR16 IIâ€â„¢ Roof
How To Obtain A Warranty:
To obtain a warranty, the type of warranty should be specified on the contract when ordering the building. The costs
involved in obtaining a warranty can be included in the building price when requested during estimating, or may be
calculated using information found in the Warranty Instruction Guide. The warranty price will then be included in the
contact price listed on the contract.
Materials for buildings requiring UL® certifications must be available for inspection on the plant floor. After the building
order has shipped, Nucor cannot issue or add warranties to the contract.
Upon shipment of the building, the Builder will be invoiced for the building, tax, and freight, less the warranty amount. The
Builder will also be issued the “Request for Warranty†document containing cost information and a compliance with Nucor
specification statement from the Builder. To obtain the warranty, simply attach the appropriate check, sign the document,
and forward to Nucor. The Builder’s signature represents to us that the products have been stored and installed properly.
Upon receiving the documents and appropriate check, the warranty is then issued.
Warranties are issued when all of the Nucor invoices for the project are paid and the “Request for Warranty†document is
signed. A check for the appropriate amount is to be included with the request. No warranties will be issued until the
project has been paid for in accordance with order terms and conditions.
The Responsibility of the Builder is:
• To ensure that the building materials are unloaded and stored properly upon receipt.
• To carefully and thoroughly erect the building in the manner set forth by MBMA and the Nucor Building Systems erection
documents.
• To maintain proper documentation on the progress and conditions of the building project.
• To follow-up on the building project during and after completion.
• To follow-up and collect samples in the event of a warranty claim.
Warranties issued by Nucor represent reasonable expectations of the products involved under normal conditions. History
tells us that most warranty claims arise from improper storage, installation, or from foreign exterior irritants (debris,
pollutants and the like). History also tells us that with the proper storage and construction techniques, the panel coverings
offered by Nucor give owners years of low maintenance service.

Preventative Maintenance Manual
V. Builders Warranties
Check with your Builder and/or Contractor to see what they offer as warranties. A warranty is never a replacement for
professional installation or reasonable maintenance. There are a number of very well designed and manufactured
products on the market, but unless the erector installs these products in accordance with the manufacturer’s directions,
their performance becomes unpredictable. Roofs that perform well for the first two to five years, will continue to perform
many years thereafter. It is important to note that a leak found early can be repaired quickly and in accordance with
manufacturer’s recommendations. Tar, pitch, or topically applied caulks are never an approved method.
Should you ever have a claim on a metal panel, the first step is to find the warranty and notify the Contractor who installed
the product. He will notify the manufacturer. If you do not have a written warranty, you will most likely be advised that you
have accepted the product “as is, where isâ€.
A jobsite visit or review of a roof system by a Nucor representative does not assume responsibility for the roof from the
owner. There are many hidden details and discrete sealants that are impossible to visually inspect. We cannot inspect
quality into a product. Quality must be built in. Once a roof is installed incorrectly, it is like “unscrambling†and egg to make
the repair. During the first two years, all leaks are handled by the buyer. This is reasonable and customary in our industry.
For the remaining warranty years both Nucor and the Buyer work together to remedy issues with the roof. Each party is
responsible for their respective scopes of work. The contractor warrants labor; the manufacturer warrants material. A
responsible contractor has no problem standing behind their work.
We will be happy to review the roof with our customer (and his erector). Nucor will provide a written report to our customer
of our findings. If corrections are required Nucor will provide our recommended repair. The contractor will take
responsibility for the life of the warranty.
