Abstract
Abstract A roof construction for use upon a deck or pre-existing roof which includes a series of elongated coplanar roof panels assembled edge-to-edge at their ends in a line and top-to-bottom at right angles thereto juxtaposed over said roof or deck. Each roof panel comprises a thin metallic skin having a rectangular top plate with a downturned front edge along its length. Below the front edge is an assembly slot bounded by an outturned anchor plate adapted for securing to said roof. A series of snap lock stops are formed in said panel and extend into said assembly slot. The top plate has a downturned rear edge which terminates in a flexible outturned assembly plate spaced from and projecting rearwardly of the top plate. The assembly plate terminates in a reverse-turned snap lock flange which extends above said assembly plate. An elongated body of foam plastic material underlies the top plate, the assembly plate and is anchored within the panel with its bottom surface extending to the anchor plate adapted to cooperatively engage the deck or roof. The assembly plate and underlying portion of said body defines a tongue which is snugly nested within the corresponding assembly slot of an adjacent panel, with the lock flange of the one panel snapping into interlocking retaining engagement with the snap lock stops of the adjacent panel.
