About Shingle‑Mate® Roof Deck Protection

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,2 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).
