Your roof is a valuable asset that must be properly maintained. All roofs and the Roofing System require periodic inspection and maintenance to perform as designed and to keep your NCC Limited Warranty in full force and effect. 

1. The roof should be inspected at least twice yearly and immediately after any severe storms. A record of all inspection and maintenance activities must be maintained. All metal work, including counter-flashings, skylights, equipment curbs, supports, and other rooftop penetrations, must be properly maintained at all times. Particular attention must be paid to sealants at joints in metal work and flashings. If cracking or shrinkage is observed, the joint sealant should be removed, and the areas cleaned thoroughly. New sealant and reinforcing Tietex T272 fabric should then be applied allowing time to dry. Apply a final topcoat of a National Coatings’ product to complete the repair. 

2. The Roofing System should not be exposed to acids, solvents, greases, oil, fats, chemicals and the like. If the Roofing System is in contact with any such materials, these contaminants should be removed immediately, and any damaged area should be inspected by a National Coatings Approved Applicator and repaired, if necessary. 

3. The Roofing System is designed to be a waterproofing membrane and not a traffic surface. Roof traffic other than periodic traffic to maintain rooftop equipment and conduct periodic inspections should be prohibited. In any areas where periodic, regular roof traffic may be required to service rooftop equipment or to facilitate inspection of the roof, protective walkways should be installed by a National Coatings Approved Applicator as needed to protect the roof surface from damage. 

4. Consider an annual low pressure washing of the roof membrane to maintain optimum solar reflectivity. Remove and kill any microbial growth by incorporating a diluted bleach solution into the pressure wash cleaning. 

5. Should you experience a leak in your roof; 

• Check for the obvious: clogged roof drains, loose counter flashings, broken skylights, open grills or vents, broken water pipes. 

• Note conditions resulting in leakage. Heavy or light rain, wind direction, temperature and time of the day the leak occurs are all-important clues to tracing roof leaks. Note whether the leak stops shortly after each rain or continues to drip until the roof is dry. If you are prepared with the facts, the diagnosis and repair of the leak can proceed more rapidly. 

• Contact National Coatings Warranty Claims Department at 800-423-9557 as soon as possible. 

National Coatings Corporation believes that the preceding requirements will assist you, the building owner, in maintaining a watertight roof for many years. Your roof is an investment, and maintenance is essential to maximize your return on this important investment.
