HydraShell MAX, a standard synthetic underlayment, and HydraShell Supreme SA, a peel-and-stick underlayment, are McElroy Metal’s new underlayment offerings. HydraShell MAX’s four-layer construction can be used under all types of finished roofing materials, including steel roofing. It can be used on roof slopes as low as 1/2:12 and requires fewer fasteners. HydraShell Supreme SA is a suitable option for high-temperature, self-adhering applications. The SBS modified asphalt offers pliability, and the cool gray surface reduces heat buildup.
