HydraShell Supreme SA is the best choice in self-adhering synthetic underlayment for exceptional high-temperature and water protection. Made from polymer-modified asphalt, it features excellent pliability along with durable high-tensile and tear strengths. Backed by a 30-year limited warranty, you can rely on Marco’s performance long-term, protecting your building investment and offering peace of mind.
HydraShell Supreme SA is a peel and stick, self-adhering solution that provides superior leak protection for standard roofing areas plus valleys, ridges, coping joints, chimneys, vents, formers, skylights and low-slope sections. Exceptionally durable and pliable, HydraShell Supreme SA adheres to a wide variety of substrates. The split-back release film peels off easily to simplify installation, while a cool-gray surface to reduce heat build-up and a 90-day UV exposure rating for extended installation periods eases the process as well.
