Deck-Armor™ Premium Breathable Roof Deck Protection

Protect Your Home With Premium “Breathable” Roof Deck Protection

Premium Roof Deck Protection should protect your home and reduce trapped moisture at the same time (amazingly, most so-called premium products do NOT!)

It 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. In addition, premium-quality roof deck protection will:

  • “Breathe”…

    To allow moisture from inside your attic to escape (to help prevent structural decay, mold, and mildew)

  • Provide Longer-Lasting Leak Protection…

    Than conventional “felts” (which can rot or become brittle before your shingles reach their useful life)
