Feltbuster

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. Enhanced Walkability — Special spunbound surface helps provide increased traction versus typical asphalt felts. Tough Synthetic Construction — Resists tearing and will not absorb moisture, become brittle, or leach oils. Cooler to Work On — Medium-gray surface is up to 30° cooler than typical black asphalt felts (Based on GAF testing with underlayments installed on plywood deck at 90°F (32.2°C) ambient temperature and left exposed to direct sunlight). Easy to Work With — Super-lightweight, 10-square, 48 in. (1.23 m) wide roll (versus typical 36 in. [914 mm] wide felt rolls). Durable — Non-asphaltic polypropylene construction for long-lasting performance (unlike conventional felts that can disintegrate over time). A Better-Looking Roof — Lies flatter than typical felts and avoids “telegraphing” of wrinkles, which can detract from the look of the new roof.
