Abstract
A fire resistant, self-adhesive rolled roofing membrane is used on low sloped roofs for insulating a surface from weather. The roofing membrane includes an asphalt-saturated fibrous material having a roofing surface area, for example, roofing granules on a portion of the top surface and a clean surface area on another portion of the top surface. The roofing membrane includes an adhesive surface area on a portion of the bottom surface opposite the roofing surface area and a parting agent covered surface area on another portion of the bottom surface generally opposite the clean surface area to prevent adhering to the clean surface area when rolled. The adhesive surface area includes a layer of self-adhesive material, such as rubberized asphalt, capable of adhering to the clean surface area when strips of the roofing membrane are overlapped. The adhesive surface area is covered with a release backing to prevent adherence to the roofing surface area. The fibrous material is saturated with an oxidized asphalt with mineral filler and the rubberized asphalt adhesive material is minimized to provide fire resistance.
