      1See GAF Shingle & Accessory Limited Warranty for complete coverage and restrictions. The word “Lifetime” refers to the length of coverage provided by the GAF Shingle & Accessory Limited Warranty and means as long as the original individual owner(s) of a single-family detached residence [or the second owner(s) in certain circumstances] owns the property where the shingles are installed. For owners/structures not meeting the above criteria, Lifetime coverage is not applicable. Lifetime limited warranty on accessories requires the use of at least three qualifying GAF accessories and the use of Lifetime Shingles.
      2RoofPro™ SBS-Modified All-Purpose Underlayment has earned the Good Housekeeping Seal (applicable in U.S. only).
      3Do not install under metal roofs. Contact GAF Technical Services at 1-800-ROOF-411 or visit gaf.com for acceptable non-asphaltic roofing systems and limited warranty coverage.
      460-day UV resistance refers to standardized testing conducted by GAF to ensure the product will not physically degrade when exposed to UV. It is NOT related to withstanding water, snow, or wind. While RoofPro™ SBS-Modified All-Purpose Underlayment is water resistant, it is NOT WATERPROOF. DO NOT USE RoofPro™ SBS-Modified All-Purpose Underlayment as a temporary roof to protect property or possessions.
