Sahara Breathable Synthetic Underlayment

Sahara™ Breathable Synthetic Roof Underlayment

Sahara™ is a premium multilayered structure with a slip-resistant textured top surface combined with our advanced breathable Moisture Release Technology (MRT). MRT actively assists in drawing trapped moisture from within the roof system and releasing it to the outside air.

Breathability is key to preventing mold, mildew and possible structural damage. Specifying Sahara™ breathable underlayment gives you the competitive edge by providing your clients the confidence and security they are looking for to compliment their premium lifetime warranty roofing system.

Using Sahara™ breathable underlayment allows roof decks that have been exposed to rain or snow during construction to dry after the primary roof has been installed.

Sahara’s textured slip-resistant walking surface provides superior steep-slope walkability, productivity, comfort and increased safety for roofers. Sahara™ is designed for use under asphalt shingles, concrete and clay tiles, all metal panels, synthetic shingles and primed cedar shakes. Sahara™ meets all the code requirements including ASTM D226, ASTM D4869 and AC 188 as required by ICC-ES.

Installing Sahara™ breathable synthetic underlayment with Moisture Release Technology helps keep your projects dried-in during new construction or re-roofing and assists in drawing moisture out of the attic space for the lifetime of the roofing system.

Sahara™ combines mechanical slip-resistance with Nexgen surface grip technology for unmatched walkability you can trust – every time.

Sahara™ is up to 13 x stronger than felt! Sahara™ stays secured to the deck in all weather conditions and minimizes tearing around fasteners†.

At 48" wide, Sahara™ is 33% wider than a traditional roll of 36" felt. With fewer laps and longer rolls, installations are faster and easier.
