This invention, in embodiments, relates to a roll comprising a roofing material. The roofing material includes a substrate having a first side and a second side, and a film layer attached to at least one of the first side or the second side of the substrate, the film layer comprising a polymer and having a thickness of 0.5 mils to 100 mils. A single layer of the roofing material achieves a Class A rating for steep slope roofing systems when tested according to UL 790 and/or ASTM E-108 Standard Test Methods for Fire Tests of Roof Coverings. This invention, in embodiments, further relates to a roofing material and a steep slope roofing system.

The invention relates to a novel binder system and its use for bonding textile fabrics as well as products containing such bonded textile fabrics. The materials according to the invention are suitable for manufacturing base interlinings which may be used for manufacturing base interlinings for sarking, roofing and sealing membranes, particularly for manufacturing coated sarking, roofing and sealing membranes.

The present invention relates to a method of producing a fabric impregnated with an aqueous binder composition of thinned starch and optionally non-thinned starch. In one aspect, such a method includes providing an aqueous binder composition; providing a fabric, applying an aqueous binder composition to the fabric; and drying the fabric. The invention also relates to the fabric obtained and the use thereof in bituminous membrane layer.

A surface-reinforced bitumen roofing membrane includes at least two layers, namely 1) a bitumen compound layer, and 2) a fiber mat, and can optionally include a) an optional bleed blocker layer that is located between the bitumen compound layer and the fiber mat, b) an optional liquid applied coating that partially or fully encapsulates the fiber mat, c) an optional release liner that is releasably positioned on the bottom surface of the bitumen roofing membrane, and/or d) an optional release film that is releasably positioned on the fiber mat surface.

The present disclosure relates generally to roofing elements and methods for making them. In one embodiment, the disclosure provides a roofing element in the form of a roofing shingle that includes a body of a foamed cured cross-linked polymer, the body having a top surface and a bottom surface, the body extending substantially in a plane and having a thickness in the range of 0.5 mm to 35 mm; and a layer of weather-resistant roofing granules disposed on and adhered at the top surface of roofing element. The roofing element can be made by providing a body of wet foamed curable composition, and allowing the curable composition to cure to provide the body of foamed cured cross-linked polymer.
