Abstract: A self-adhering modified bituminous underlayment for metal roof assemblies that comprises an APP modified bitumen compound on the front side, and a factory-applied self-adhesive compound on the back side of a reinforcement carrier sheet, and a fabric at least partially embedded in the APP modified bitumen compound to provide a non-skid surface.

Abstract: A self-adhering modified bituminous roofing tile underlayment material for tile roof assemblies that comprises an APP modified bitumen compound on the front side, and a factory-applied self-adhesive compound on the back side of a reinforcement carrier sheet, and granules embedded on the APP modified bitumen compound to provide a non-skid surface.

Abstract: A high strength polymeric composite laminate that has enhanced design features to perform as a roofing underlayment material for use in conjunction with modified bituminous materials such as APP or SBS membranes, as well as shingles, tiles, metal and other roof coverings.

Abstract: A self-adhering modified bituminous roof covering composite that comprises an APP modified bitumen compound on the front side, and a factory-applied self-adhesive compound on the back side of a reinforcement carrier sheet. A method of manufacturing such composite comprising coating an APP compound on the top surface and affixing a self-adhesive compound to the bottom surface of a reinforcement carrier support sheet, and applying a release liner to the tacky self-adhesive layer during manufacture, stripping the release liner, selvage release film and end lap film from the membrane immediately prior to use, subsequently placing the exposed surface of the membrane directly on to the upper surface of the roof deck, base sheet or underlayment, and applying force directly to the sheet to enhance the bond between the composite and the underlying surface that is created by the tacky self-adhesive compound. The present invention relates generally to residential and commercial roofing membranes and shingles.

Abstract: A reflective and emissive surface film laminate specially designed to form a top surface of modified bituminous roof covering composite such as membranes, underlayments and shingles to constitute a roof with thermal characteristics with substantially reduced amount of radiant energy entering a structure with such a covering.

Abstract: A modified bituminous roof covering composite such as membranes and underlayments that comprise a thermoplastic (atactic polypropylene), elastomeric (styrene-butadiene-styrene) or thermoplastic polyolefin (TPO) modified bituminous roofing material with a reflective and emissive surface laminate forming a top surface of the composite to constitute a roof with thermal characteristics which substantially reduced the amount of radiant energy entering a structure with such a covering.

Abstract: A self-adhering modified bituminous roof covering composite that comprises a thermoplastic (APP), elastomeric (SBS) or TPO modified bitumen compound on the front side, and a factory-applied self-adhesive compound on the back side of a reinforcement carrier sheet, with factory-applied tracts of adhesive on the side lap and end lap sections of each roll to enhance adhesion.
