Atlas considers shingles to be the final layer of a well designed roofing system. That being said, what goes under your shingles is just as important as the shingles themselves, if not more.
Atlas inorganic fire retardant underlayments, or slipsheets, enhance the overall fire performance of many conventional commercial roof insulation systems, including metal roofs.
Gorilla Guard® 30 and Gorilla Guard® SPEC 30 are designed to outperform traditional felt roof underlayment by combining specially developed additives with glass fibers. The superior quality, time and labor saved by using Atlas engineered underlayment encourages more contractors to offer it to customers as a standard product rather than as an upgrade to traditional felt.
Summit® 60 and Summit® 180 synthetic underlayments are ideal for standard application for steep-slope roof assemblies. They are premium quality synthetic roof underlayments that provide 10 squares per roll, a benefit to wholesalers, shippers and installers alike. Woven scrim synthetic roof underlayment enhances tear resistance and lays flat while guarding against moisture and mold growth.
WeatherMaster® self-adhesive underlayment features an SBS-modified asphalt membrane, providing a secondary layer of waterproofing protection against damage caused by extreme weather. This specialty underlayment is designed to go under several types of steep-slope roofing materials, including asphalt shingles, metal roofs and tile.
