About FeltBuster® Synthetic Roofing Felt

FeltBuster® Synthetic Roofing Felt is a value-priced upgrade for typical asphalt felts that helps provide long lasting protection against wind-driven rain from infiltrating under your shingles.  It’s a key part of the GAF Lifetime Roofing System1 and has even earned the Good Housekeeping Seal.2
  • Enhanced Walkability:  Special spunbound surface helps provide increased traction vs. traditional asphalt felts.
  • Durable Construction:  Non-asphaltic, polypropylene construction for long-lasting performance – unlike conventional felts that can disintegrate over time.
  • Competitively Priced:  Per square with typical asphalt felts (pricing varies by market).
  • A Better Looking Roof:  Lies flatter than typical felts and avoids "telegraphing" of wrinkles, which can detract from the look of your new roof.  
  • UV Stabilized Polypropylene Construction:  Resists UV degradation for up to 90 days.3

This product can be used to comply with certain FORTIFIED Roof™ requirements. Visit gaf.com/fortified and current FORTIFIED Home™ Standard available at fortifiedhome.org for details. Applicable in the U.S. only.
