* Check limited warranties for complete coverage and restrictions. Also note that the word “lifetime” means as long as the original individual owner of a single-family detached residence (or the second owner in certain circumstances) owns the property where the shingles are installed. For owners/structures (e.g., a church) not meeting the above criteria, the warranty term is 40 years. Installer certification is only for installations covered by GAF system warranties. Maximum wind coverage requires special installation. See warranty for complete coverage and restrictions.
