StormTread Roll

Whether you’re roofing projects are new construction or re-roofing, If you're serious about quality, StormTread™ is the ultimate synthetic underlayment for use under all tiles. You’ll nod at how good it feels to walk on. You’ll admire how durable it feels. And you’ll love that it wont burn a hole in your pocket.

One of the key features of StormTread™ is our micro-etched surface technology. It provides excellent slip-resistant properties and the superior steep-slope walkability that roofers regard as best in class.

StormTread™ is designed for use under tiles but it can also be used under asphalt shingles, all metal panels, synthetic shingles and primed cedar shakes. StormTread™ meets and exceeds all code requirements including: ASTM D226, ASTM D4869 and AC 188 as required by ICC.

StormTread™ not only protects roof decks, it helps to protect Roofers as well. Ask for it at your nearest roofing distributor today.

No more felt blow-offs!
StormTread™ is up to 13x stronger than felt! †StormTread™ stays secured to the deck in all weather conditions and will not tear around fasteners.

Quicker, smoother and up to 450% more coverage
StormTread™ is wider, longer and has fewer laps then felt. It lays flat and will not wrinkle or distort when wet.

Fewer trips up the ladder
A 5,000 sq. ft. roof requires as few as 5 rolls of StormTread™ vs. 24 rolls of #30 felt.

Save money

Leak protection for less
The decrease in cost to use StormTread™ in place of felt is about$0.02–$0.08 per square foot. For a fraction of the overall installation cost, homeowners and roofing contractors alike can rest assured knowing that their roof is securely protected not only during construction but also against the event of primary roof failure.
