ABSTRACT:
A device lot terminating a roof surface at a vertical edge In a waterproof and airtight manner may serve as a flashing strip at a parapet wall, a wall cap, a roof edge, an expansion joint or in other roofing applications. The device comprises a relatively rigid member, typically of sheet metal or the like, and a flexible member, typically of modified coal tar bitumen, EPDM, or other suitable roofing material. The device has a channel formed in the rigid member along a longitudinal edge that receives the flexible member in an airtight and watertight manner. In this configuration, the flexible member provides a covering for the fastening surface on the rigid member, which is fastened by conventional means to the roofing surface and the underlying support structure. The preferred channel is formed from a pair of longitudinal bends made in opposite directions such that a "Z" shape cross section is formed. The edge of the flexible member is coated with an appropriate sealant, positioned into the channel and compressed into place. In some applications, at least one portion of the first member near the first bend forming the "Z" shape cross section is embossed into the first edge of the second member, as achieved by a metal press brake, with the press brake in some instances perforating the first member at the point of embossing.
