GAF ELK Deck Armor™
Premium Breathable Roof Deck Protection

Protect Your home With Premium "Breathable" Roof Deck Protection

<< Back to Roof Deck Protection

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

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, a 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)
     
  • Lay flatter
    so your shingles will lay flat and uniform

WARNING:

“If your roof can’t breathe, the result can be decay, mold, mildew and costly structural damage!"

Today’s modern homes are built weathertight — so common moisture (from cooking, bathing, cleaning, etc.) has less chance to escape. Using non-breathable roof deck protection can create a barrier that traps harmful moisture inside your roofing system. Over time, that can cause roof rot, mold, mildew and costly structural decay.

That’s why GAF-Elk does not recommend the use of non-breathable roof deck protection under its shingles!
