An extra layer of fiberglass-reinforced protection between your shingles and your roof deck that helps prevent wind-driven rain (or water from other sources) from infiltrating under your shingles and causing damage to your roof structure or the inside of your home
Great Look
Fiberglass-reinforced, so it lies flatter than conventional organic felt for a more uniform look
Reliable Protection
Eliminates the need to slit bubbled felt, which may be required when using conventional organic felt (this can compromise the integrity of your roof system)
Peace of Mind
Eligible for up to a Lifetime ltd. warranty when installed on Lifetime Shingle roofs1


Help protect your new roof with quality roof deck protection. Shingle-Mate® Roof Deck Protection helps to prevent wind-driven rain from infiltrating the roof system. Shingle-Mate® Roof Deck Protection is a key part of the GAF Lifetime Roofing System,1 and has earned the Good Housekeeping Seal.2

  • Looks Better:  Fiberglass reinforced, so it lies flatter than typical felts reducing the "telegraphing" of wrinkles, which can detract from the look of your new roof.
  • Versatile:  Can be applied over plywood, wood plank, and all other approved decks.3
  • Better Protection:  Eliminates the need to slit bubbled felt, which may be required when using conventional organic felt - doing so can compromise the weather-resistant integrity of your roofing system
  • Great Value:  Competitively priced with #30 felt on a per square basis (pricing varies by market).

NOTE: Shingle-Mate® Roof Deck Protection must NOT be left exposed to moisture or precipitation.
