Atlas Roofing Corp., Atlanta, offers WeatherMaster high performance underlayment. The product creates a weather-tight barrier over the roof deck and blocks rain and ice buildup in problematic areas such as valleys, eaves, flashings, hips, ridges and rakes, and around dormers and skylights. The underlayment is designed for use under all popular roof coverings, including tile, wood shake, slate, asphalt or metal. WeatherMaster has a self-adhesive, tear-resistant backing that seals to the deck for easy installation and a skid-resistant surface for better traction and safer application of shingles. The rolls are packaged for easier roll out, less sticking, and flatter installation with less curling.
