In response to contractor demand for a high-performance, budget-friendly underlayment, CertainTeed® has developed DryRoof™ SA. The underlayment is specifically designed to withstand high levels of moisture while providing contractors with ease of installation and the ability to offer manufacturer-backed extended roof system warranties.
The newest addition to CertainTeed underlayment products, DryRoof SA is lightweight and prevents water intrusion via watertight seals around fasteners and roof penetration points. Designed for use with asphalt shingles, this cost-conscious and self-adhering underlayment features a split-release backing, allowing for speedy and secure installations.
