StormTread™ is an engineered synthetic roofing underlayment for sloped roof applications. StormTread™ has a mechanical slip-resistant walking surface which provides superior steep-slope walkability and increased safety for roofers. In addition, StormTread™ has a uniquely designed coating technology which allows the underlayment to be anchored to the deck prior to using fasteners. StormTread™ is designed for use under asphalt shingles, concrete tiles, all metal panels, synthetic shingles and primed cedar shakes. StormTread™ not only protects your roof, it helps to protect roofers as well.
