Roof shingle warranties are only as good as the materials and installation.

National Roofers' roof replacement service is done according to manufacturers' warranty requirements. Shingle warranties are related to:

Shingle Installation - When reroofing a house, the old shingles and underlayment must be removed before new shingles are installed. Otherwise, many manufacturers won't honor the shingle warranty. Likewise, certain roofing, such as architectural shingles, must be properly installed to attain the stated wind protection. 

Shingle Material & Construction - GAF uses the best roofing materials to protect your home from extreme weather.  Other components provide added fire protection and longer shingle life. When installed by a GAF Master Elite Roofing Contractor such as National Roofers, additional warranty length and protection is available.

During your in-home appointment, a National Roofers expert will show you actual samples of various Owens Corning roofing shingles, and explain the warranty on each product. The chart below is just an example of the products we recommend and their warranty periods. Further information is available when you browse GAF roofing shingles online.
