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.

In a roof construction for use upon a deck or pre-existing roof, a series of elongated coplaner roof panels assembled edge-to-edge at their ends in a line, and top-to-bottom in a line at right angles thereto, juxtaposed over said deck or roof; each roof panel comprising a thin metallic skin having a rectangular top plate; a downturned front edge along its length; said front edge terminating in a return plate, which terminates in a downturned upright wall, in turn, terminating in an outturned anchor plate spaced from and projecting forwardly of said top plate; and defining with said return plate an assembly slot; a series of aligned struckout snap lock stops formed in said return plate and extending into said assembly slot; a downturned rear edge along the opposite edge of said top plate; said rear edge terminating in a flexible outturned assembly plate spaced from and projecting rearwardly of said top plate; a reverse-turned snap lock angle flange at the edge of and extending above said assembly plate; an elongated body of foam plastic material underlying said top plate, said assembly plate and projected into portions of said panel between said top plate and return plate and anchored therein; its bottom surface extending to said anchor plate and coplanar therewith and adapted to cooperatively engage said deck or roof; and a series of fasteners securing said anchor plate to said deck or roof; the assembly plate and underlying portion of said foam plastic body along one edge of a panel defining a tongue snugly nested within the corresponding assembly slot along the opposite edge of an adjacent panel with said lock flange of one panel snapping into interlocked retaining engagement with snap lock stops of said adjacent panel.
