Owner's Guide for a Nucor Roof

The roof of your Nucor building is an area that is seldom seen and consequently too often forgotten in planning routine building care. Nucor roof systems are designed to withstand severe weather conditions and provide years of maximum protection at the lowest possible cost; however, as with any roof system, some maintenance and care is required to give the roof the most service to the owner. Following these simple suggestions will greatly enhance the probability of continuing trouble-free service.
1. Protect the Roof from Foot Traffic
  Roof traffic should be kept to an absolute minimum. Always walk in the flat of the panel between the corrugations, and as much as possible walk at or near the supporting roof structurals. Observe good, safe habits while on the roof and obey all OSHA or applicable regulations.
  Where frequent or heavy traffic is anticipated, use roof service ways to protect the roof. This is particularly helpful where regular servicing of roof-mounted mechanical equipment is required or during the installation of such equipment that was not part of the original construction.
2. Roof Mounted Equipment
  Roof mounted equipment should be maintained to prevent rust of support steel from dropping on the roof surface and to prevent any drainage onto the roof surface that might contain corrosives.
  Water drippings from bare copper wire, copper pipe, or copper flashings contain ions that are corrosive to the roof. These items and adjacent panels should be painted to minimize the problem if the copper source cannot be eliminated. Areas subject to run-off from lead or copper will void the warranty. Condensate from air conditioners or evaporators should never be allowed to drain directly onto the roof. This condensate shall be piped off the roof to drains. Plastic pipe is recommended. Never use copper pipe. Steel pipe is also undesirable unless painted.
3. Restore Sealants Arount Roof Openings
  Sealants around roof openings for mechanical equipment, ventilation, roof jacks, etc., are particularly susceptible to deterioration from weathering. These areas should be inspected annually and resealed as needed.
4. Keep Roof Free of Debris and Markings
  Roof and gutters should be kept free from debris. The roof should be inspected periodically and any debris removed. Gutters and downspouts should be cleaned as necessary. Careful clean-up of all materials and debris following any roof activity or maintenance is extremely important. Drill chips, wire, metal scrap, insulation, and other debris left on the roof to weather and corrode can be very damaging to metal roof materials, and therefore should be removed immediately. When identifying areas that require maintenance, do not use pencil lead. Pencil lead will corrode GalvalumeĀ®.
  Tip: Use clothes pins (on the seams) or colored electrical tape.
  Also, flying debris from tools such as abrasive saws (hot saws) and welding equipment can create much roof material damage. Extreme care and skill must be used with these tools.
5. Periodic Routine Maintenance to Seal Roof Openings
  Check for loose or missing screws and look for small holes caused by the dropping of screws and the like.
