ABSTRACT:
A single-ply, thermoplastic membrane roof construction includes, at its corners, a pair of right angularly disposed substantially rigid, edge, corner pieces welded together along a mitered joint by way of bringing a heating block into contact with the horizontal and vertical edges to be joined, and then converging the pieces to form the mitered corner which is fastened to the underlying roof structure. Strips formed of the same membrane fabric material as the roof covering membrane are welded to the horizontal upper walls of the edge pieces. Edge linear continuation strips are fastened in position to extend from the corner pieces, but with a gap between them and the corner-forming pieces. Clips mated to the configuration of the edge pieces and strips have portions at one of their upper and lower ends which snap into position to unite the spaced apart edge pieces.
