Overview

Model # 902000 Store SKU # 1000655375

Shingle-Mate® Roof Deck Protection provides a critical layer of protection under your shingles against wind-driven rain and other sources of moisture. Unlike typical asphalt felts, it's fiberglass-reinforced to help avoid wrinkling for a better-looking finished roof.

  1. Fiberglass-reinforced construction lays flat for an attractive roof appearance and avoids telegraphing wrinkles through your shingles
  1. Each 36-Inch x 144-Feet roll of Shingle-Mate Underlayment covers approximately 432 sq. ft., excluding laps
  1. Each roll equates to 2 rolls typical #30 asphalt felts, resulting in less rolls to load and install on the roof
  1. Helps eliminates the need to slit wrinkled felt (which can compromise the integrity of your roofing system)
  1. For use with asphalt shingles and can be used over plywood, wood planks and other approved decks for versatility
  1. NOTE: Shingle-Mate® Roof Deck Protection must NOT be left exposed to precipitation
  1. Shingle-Mate® Roof Deck Protection is a key part of the GAF Lifetime Roofing System and is backed by up to a Lifetime Limited Warranty when installed on lifetime shingle roofs

Rated 2 out of 5 by from DON'T LET IT GET WET! This stuff goes on fine. It feels pretty tough but DO NOT LET IT GET WET! I was hoping it could withstand a few days of potential rain while I installed the shingles but it got damp from fog and wrinkled up like waves on the ocean. How is this ever going to protect a roof from water? It's absorbent and soft. There MUST be a better product than this.

What is the difference between this and the felt paper (#15, #30)? Thanks,

Asked by: alan a
Dear Alan, our Shingle-Mate Roof Deck Protection is comparable to typical asphalt roofing #30 Felt, but is fiberglass reinforced which allows the product to lay flat and avoid wrinkling, for a better looking finished roof.

How does this attach to the plywood? Staple Gun? Torch?
