Deck-Armor's 10-square roll format suits larger residential reroofs, reducing roll changes on the roof. Verify exposure and fastening patterns against GAF's application instructions and your local code. For full system warranty eligibility, confirm which GAF underlayment your chosen shingle warranty requires.
Synthetic underlayment can be slippery, especially when wet or on slopes; wear slip-resistant footwear and use fall protection.
