Quality roofing underlayment is critical for helping to prevent wind-driven rain from infiltrating under the roof's shingles and potentially damaging the home's structure and interior. Traditional asphalt felt underlayments tear easily and absorb moisture, leading to wrinkling that telegraphs through the shingles. Competitively priced with typical #15 and #30 asphalt felts, GAF FeltBuster High-Traction Synthetic Roofing Felt is virtually untearable and will not absorb moisture, helping to prevent wrinkling. Its specially designed surface combines enhanced walk ability with a cooler working surface (versus black asphalt felts). Part of the GAF Lifetime Roofing System, FeltBuster High-Traction Synthetic Roofing Felt is covered by up to a lifetime limited warranty when installed on lifetime shingle roofs.
