Questions about GAF roofing products.
Does GAF make more than roofing shingles?+
Yes. GAF offers shingles and multiple roof-system components, along with residential low-slope and commercial roofing products.
Do all GAF roofs receive the same warranty?+
No. Coverage depends on the products installed, accessory requirements, contractor eligibility, registration, property type, and the written warranty.
Does using matching accessories matter?+
It may. Certain system and enhanced warranty options require qualifying GAF accessories in addition to the field shingles.
Does a GAF warranty cover storm damage?+
Standard product warranties generally focus on qualifying manufacturing defects. Wind, hail, trees, and other storm damage are typically handled separately.
