The invention provides a quickly installed and preferably reusable flashing unit for use in roofing or cladding of a building. The flashing is constructed of stainless steel sheet metal for superior corrosion resistance and to withstand rough handling as old roofing material is scraped off the flashing surfaces to prepare it for reuse. The flashing is assembled along joints between assembled flashing components. Each joint includes a resilient gasket between opposing edges of adjacent flashing components. Clips join the components together and resiliently compress the gasket between opposing edges of the adjacent components. After assembly around stacks, openings, edges or other roofing discontinuities, the flashing is incorporated into the roofing in a conventional manner. The invention provides, in its broad aspect, a novel flashing unit for weatherproofing a discontinuity in an external weatherproof membrane, said flashing being assembled along at least one joint, a portion of said joint being covered by said membrane, said flashing comprising: first and second components, each component having an opposing edge disposed at a distance from the opposing edge of the other component, thus defining said joint; gasket means, abutting each said edge, for resiliently sealing said joint; and clamp means, for joining said components and for sealingly compressing said gasket between said opposing edges. Three variations of the gasket and clamp means are described herein.
