GAF FeltBuster Synthetic Underlayment provides a critical layer of protection from moisture and water to your roof system.
Lifetime refers to the length of warranty coverage provided and means as long as the original individual owner(s) of a single-family detached residence [or the eligible second owner(s)] owns the property where the qualifying GAF products are installed. For other owners/structures, Lifetime coverage is not applicable. Lifetime coverage on shingles requires the use of GAF Lifetime Shingles only. Lifetime coverage on shingles and accessories requires the use of any GAF Lifetime Shingle and any 3 qualifying GAF Accessories. See GAF Roofing System Limited Warranty for complete coverage and restrictions.
For installations not eligible for the GAF Roofing System Warranty, see the GAF Shingle & Accessory Limited Warranty.
FeltBuster Synthetic Roofing Felt has earned the Good Housekeeping Seal (applicable in U.S. only).
90-day UV resistance refers to standardized testing conducted to ensure the product will not physically degrade when exposed to UV. It is NOT related to withstanding water, snow, or wind. FeltBuster Synthetic Roofing Felt is water resistant, it is NOT WATERPROOF. DO NOT USE FeltBuster Synthetic Roofing Felt as a temporary roof to protect property or possessions.
