Synthetic Underlayment

Numerous types of synthetic roll materials are available as underlayment in steep slope roof assemblies. Compared to traditional organic felt, the lightweight of synthetic underlayment permits many more squares per roll, which can be an economical benefit to wholesalers, shippers, and installers alike. While non-woven mats are generally moisture permeable, woven scrim synthetic roof underlayment greatly enhances tear resistance and lay-ability.

Atlas used this information to create a line of inorganic, high strength woven fabric synthetic underlayment that includes Summit® and Summit® 60.

As an alternative to traditional #30 and #15 organic felt underlayment, Summit® and Summit® 60 synthetic roof underlayment are designed to provide greater strength, longer exposure, and safer walkability, while offering water-shedding capabilities within the roof system to protect the structure from water damage. Unlike plastic films, which can be very slick, causing an unsafe environment for the installer walking on a steep slope roof, Atlas Synthetic Underlayment have a unique textured surface to provide safer walkability.
