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.
In cold climates, where snow and ice are common, an ice-dam protection membrane is recommended on downslope roof perimeters (e.g. eaves), valleys, and around penetrations.
