ABSTRACT:
An expansion joint for roofs and the like, especially for the sheet-metal flashing or cover plates of the finial, cresting or ridge of flat roofs, comprises a pair of metal strips defining an expansion gap between them. The gap is bridged on the underside of the joint with an elastomeric sealing band bonded, e.g., by vulcanization, to the metal strips and covered, on its side turned toward the environment with an intermediate metal strip slidingly held in place by the elastomeric band so as not to impede relative displacements of the first two metal strips upon thermal expansion and contraction.
