ABSTRACT:
A flashing assembly that incorporates a plurality of overlapping flashing sections that are each preferably formed from a sheet material. Each section includes opposite edge portions that are arranged about a generally V-shaped configuration. Joining the sections together is at least one clinch joint that is substantially formed and registered upon the overlapping edge portions of at least two different overlapping flashing sections. The clinch joint is adapted to releasably fasten the at least two sections. Various modifications include one or more additional clinch joints that are also substantially formed upon the same overlapping edge portions of the first clinch joint and the V-shaped configuration that forms an angle of approximately 90 degrees. In other variations of the preceding modifications, the clinch joint is a mechanical press fit interference joint or a welded, press fit, or adhesive joint, or some combination or permutation thereof. Each section may also incorporate one or more attachment holes and alignment indicia. The sheet material is preferably selected from a material such as, for example, powdered, machined, drawn, stamped, rolled, extruded, and forged metals and plastics, and alloys, and combinations, mixtures, compositions, hybrids, tempers, hardness modified, and heat treated variations thereof. More preferably, the sheet material is selected from the group of materials including weather and galvanic corrosion resistant materials including, for example, aluminum, tin, bronze, copper, lead, stainless steel, galvanized metals, weather proofed metals, plastic coated metals, and alloys, combinations, mixtures, compositions, hybrids, tempers, surface treated, hardness modified, and heat treated variations thereof.
