*All GAF® shingles are subject to GAF's limited liability warranty. While many factors can affect how long your GAF Roofing System will last, this GAF Roofing System Limited Warranty covers your asphaltic shingles and accessories, including GAF Ridge Cap Shingles, GAF Starter Strip Shingles, GAF Leak Barrier Products, GAF Roof Deck Protection Products, and GAF Cobra® Attic Ventilation Products (the “GAF Products”), in the unlikely event that they contain a manufacturing defect. It provides great coverage that is “non-prorated” during the crucial up-front period of your ownership (the “Smart Choice® Protection Period”) with continued coverage for extended periods of time afterwards. Note: This limited warranty does not cover low-slope membranes or Master Flow® Ventilation Products. Please go to gaf.com for a copy of the limited warranties covering these products.
