Roofnado™ StormTread® XW

StormTread Roll

StormTread® XW is an engineered synthetic roofing underlayment for sloped roof applications. StormTread® XW has a micro-etched surface technology that provides excellent slip-resistant properties and superior steep-slope walkability for roofers.

In addition, StormTread® XW is combined with a uniquely designed coating technology which allows underlayment to be anchored to the deck without using fasteners combined with high traction walking surface for roofers safety.

StormTread® XW is designed for use under asphalt shingles, concrete and clay tiles, all metal panels, synthetic shingles and primed cedar shakes. StormTread® XW meets all the code requirements including ASTM D226, ASTM D4869 and AC 188 as required by ICC.
