DryRoof SA is a lightweight, self-adhering underlayment that provides a watertight seal around fasteners and roof penetrations to prevent leaks and water damage. 

Featuring a split-release backing for fast and secure installation, DryRoof SA is designed for use as a wind-driven rain guard along eaves, roof penetrations, and valleys. It is UV-exposure-resistant for six months, sticks well to most surfaces, offers excellent elasticity, and has a slip-resistant sand surface to reduce risk of falls. 

Designed for use in conjunction with asphalt shingles, DryRoof SA is warranted against manufacturing defects, and meets the requirements for use in a CertainTeed Integrity Roof System – providing contractors with a cost-friendly underlayment option for offering manufacturer-backed extended roof system warranties.
