Spyder PSU is a high-performance, self-adhered roofing underlayment engineered to provide unmatched protection and ease of installation on sloped roofs. Its lightweight, smooth design, combined with a split release liner and rubberized adhesion technology, ensures a stronger deck grip and faster, easier installs. Spyder PSU features a patented (pending) mechanical slip-resistant surface, offering superior walkability and enhanced safety on steep slopes. Unlike granular or mineral sand-coated underlayments, its design eliminates potential weak points, delivering exceptional waterproofing and premium protection from ice dams, snow, storms, hail, and wind-driven water. Meeting and exceeding ASTM D1970 and meeting CAN/CSA A220.1 performance requirements, Spyder PSU is a reliable choice for use under asphalt shingles, concrete and clay tiles, synthetic shingles, and primed cedar shakes, providing a durable secondary water barrier for the roof and the interior of the building with a 20-year warranty and a 45-day UV exposure rating. Custom dual-logo printing is also available.
