Designed for tile roofs, WeatherMaster® TU Ultra is a self-adhesive, synthetic underlayment consisting of a proprietary modified asphalt and woven polyester. Its polyester surface aggressively bonds with foam adhesives used in tile installation and can withstand stacked tiles without slippage or damage to membrane surfaces. WeatherMaster can also be used with slate and metal roofs. With a 60-mil high-temperature thickness, it provides excellent traction for roofers during roofing installation, along with ease of use — no special adhesive, heat or equipment is necessary when properly installed.
