DryRoof® SA Waterproofing Underlayment

Overview

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.

DryRoof SA can be used to cover the entire roof deck, serving as a valley liner, roof penetration shield, and wind driven rain guard.

Sustainability

CertainTeed is committed to creating a circular roofing shingle economy. In February 2023 we acquired Asphaltica recycling technology that lets us reclaim post-industrial and post-consumer shingle scrap. Instead of going to the landfill, the shingles are pelletized and blended into hot mix asphalt. The pellets are water-resistant and can be used in variable climate conditions.
