This warranty is considered a base coverage, which includes total roofing system coverage at 100 percent with an allowance of 10 years for materials that are determined defective. The labor cost for installation is included as well for a 10 year period. Items that are considered accessories and qualify as GAF products will also be part of the 10 year period. Shingles that qualify as GAF products are also covered for wind damage up to 130 miles per hour.
Any shingle that is associated with GAF production is subject to numerous inspections and repetitive testing, which suggests that any deterioration is unlikely, but it can occur on occasion and can be costly to repair and replace. GAF is aware of what can happen and has formulated coverage for GAF Lifetime Designer Shingles at 30 years, while GAF Timberline Lifetime shingles have 25 years of coverage, and GAF 3-Tab Shingles have 20 years of coverage.
