When you install a GAF Roofing System (defined as GAF Lifetime Shingles plus at least 3 Qualifying Accessories), you are automatically eligible for the coverage provided by the GAF Roofing System Limited Warranty – which provides the same great coverage as the GAF Shingle & Accessory Limited Warranty, but adds lifetime coverage on your Qualifying accessory products. Depending on what products you install, you may also be eligible for the WindProven Limited Wind Warranty. See GAF Roofing System Limited Warranty for complete coverage and restrictions.
