The history of roofing underlayments is a long one, a progression of needs and innovations that like the products themselves, have remained under the surface

This self-adhering “self-stick” roofing underlayment from MFM Building Products is composed of a high-grade, reinforced polyester fabric laminated to a high temperature asphalt adhesive system.

New from McElroy Metal, HydraShell MAX is the standard synthetic underlayment and HydraShell Supreme SA is a peel-and-stick underlayment.

This new group, called the Asphalt Underlayment Council, supports the standardization of underlayment quality, performance and integrity.
