The only roofing underlayment with the high performance of a synthetic underlayment and the finished look of a shingled roof. Available in energy-efficient white or tan, ShingleLayment outperforms felt, is installer-friendly, and provides both durable temporary cover and long-lasting water-shedding protection. Grip-Rite ShingleLayment synthetic underlayment is a lightweight, woven polypropylene underlayment coated with a non-skid TPO. ShingleLayment possesses very high tensile and tear strength that resists tearing, ripping, and blow-offs from high wind exposure. ShingleLayment can be used in any code-compliant mechanically attached roofing application. Grip-Rite ShingleLayment synthetic underlayment is used on steep-slope roofs beneath shingles, battened tiles, metal roofing, slate, wood shake, shingle, and simulated slate/shake prepared roof coverings as an alternate to ASTM D226, Type I, or II or ASTM D4869 asphalt felts. Grip-Rite ShingleLayment synthetic underlayment is a water-shedding device designed to reduce the occurrence of leaks caused by wind-driven rain penetrating primary roof system coverings, as well as damaged roof coverings and as temporary cover on exposed roof systems. Grip-Rite ShingleLayment synthetic underlayment is available with a standard installer print pattern or exclusive shingle-look print pattern (patent pending). Both print patterns feature installation and nailings grids for easy, accurate application. Grip-Rite ShingleLayment synthetic underlayment increases applicator productivity thanks to its low weight per roll and superior 10 sq. roll coverage. Grip-Rite ShingleLayment synthetic underlayment can be exposed to natural UV for up to 180 days. Severe weather, jobsite damage, chemical exposure, or other conditions may shorten exposure life.
