Deck‑Armor^™ Premium Breathable Roof Deck Protection

Breathable technology helps manage roof system moisture and provides a secondary layer of winddriven rain 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 System,¹ 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
