Abstract: Embodiments of the invention provide composite roofing strips that may be attached to a roofing membrane for aesthetic and/or functional purposes and method of attaching the same. According to one embodiment, a composite roofing strip may include a longitudinally extending body having a base and a lateral member extending from the base, and may also include an insert extending partially or fully along the body and coupled therewith. The insert may be formable so as to allow the composite roofing strip to be adjusted to have a desired profile and to maintain the desired profile of the composite roofing strip post adjustment.

Abstract: According to one embodiment, a method of making a roofing membrane is provided. According to the method, an ethylene propylene diene monomer rubber (EPDM) material sheet is provided and a thermoplastic polyolefin (TPO) material sheet is extruded onto the EPDM material sheet. The EPDM material sheet and TPO material sheet are then pressed together via one or more rollers. The EPDM material is uncured and has a thickness of between about 50 mils and 70 mils. The extruded TPO sheet has a temperature of at least 150 degrees Celsius and a thickness of between about 15 mils and 35 mils. The heat of the TPO material sheet causes a top portion of the EPDM material sheet to cure such that crosslinking of the TPO and EPDM material sheets occurs at an interface of the sheets to bond the sheets together.
