May 31, 2012

ATLANTA – Atlas Roofing Corporation’s SUMMIT® Synthetic Underlayment for steep-slope roof applications is designed for a long anticipated open time before the roof covering is installed. SUMMIT® Synthetic Underlayment is manufactured from an inorganic, lightweight, and extremely strong woven polypropylene fabric, and has UV and water resistive coatings. SUMMIT® is unaffected by exposure to water and sunlight for at least 6 months, protecting the structure throughout the roofing project. It has good walking traction, and is able to hold fasteners very well. SUMMIT® is packaged for convenience in 10 square rolls weighing less than 30 lbs. each. The product’s UL Classification demonstrates conformance to critical fire testing requirements. SUMMIT® is fully compatible with asphalt shingles, metal roof coverings, Clay Tile, Slate, Concrete Tiles, Wood Shingles and Shakes or any other code approved, steep slope roof covering.
