Overview Model # 0901 Store SKU # 1000731327

Deck-Armor provides a critical extra layer of protection between your shingles and your roof deck — to help prevent wind-driven rain (or water from other sources) from infiltrating under your shingles and causing damage to your roof structure or to the inside of your home.

  • It allow moisture from inside your attic to escape (to help prevent structural decay, mold, and mildew)
  • Provides longer-lasting leak protection… Than conventional felts (which can rot or become brittle before your shingles reach their useful life)
  • Premium roof deck protection is specially designed to allow moisture to escape
  • Unlike conventional asphalt felts, resists wrinkling or buckling, so it lets your shingles lay flatter for a better-looking roof.
  • Helps prevent inside moisture from becoming trapped within your roofing system — and causing mold, mildew, and expensive structural damage
  • Coverage: 1 roll covers 4 squares (400 square feet)
