About Deck‑Armor™ Premium Breathable Roof Deck Protection
Conventional organic felts can absorb moisture, causing buckling and wrinkling that can impact the look of your roof. Deck-Armor™ Premium Breathable Roof Deck Protection combines strength and breathability to help protect your home against wind driven rain and trapped moisture. Deck-Armor™ Premium Breathable Roof Deck Protection is a key part of the GAF Lifetime Roofing System1 and has earned the Good Housekeeping Seal.2
- Breathable Technology: Unlike typical synthetic underlayments, Deck-Armor™ helps reduce inside moisture from becoming trapped within your roofing system.
- Exceptionally Strong: At least 600% greater tear strength than standard #30 asphalt felt.3
- Safer: Special slip-resistant surface provides enhanced walkability, even on steeper-pitched roofs.
- Fast installation: 48"(1.22 m) wide roll provides 33% more coverage per course than traditional 36" (914 mm) wide felts.
- Lightweight: At approximately 43 lbs. (19.5 kg) per roll, it's lighter and easier to handle than a roll of #30 felt.
- Flexible Application: Recommended for use with asphaltic-shingle roof systems. May also be used with certain non-asphaltic systems, such as slate, wood, metal, or tile.4
- UV Stabilized Polypropylene Construction: Resists UV degradation for up to 180 days.5
- Meets UL 790 Class A fire rating
