      • 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
