Abstract: Two side-by-side roofing panels (12,14) are connected by a reinforced connecting sheet member (40) extending between the panels (12,14) and fastened to the outside surfaces of the panels (12,14). A bead (56,58) of flowable material is positioned between the connecting sheet member (40) and the outside surface of at least one of the panels (12,14) in a space adjacent the respective side (18,20) so that upon movement of the panels (12,14) apart the connecting sheet member (40) will be straightened out and the flowable material of the bead (56,58) will be displaced into the gap (22) between the sides (18,20) of the panels (12,14).

Abstract: A fastener plate for use in association with a fastener in a roof structure is described. The fastener plate includes a disc-shaped plastic member that has a depending central portion extending from its lower planar face and a depending peripheral flange. A metal insert seated in an opening within the plastic member contains an opening through which the fastener can be threaded.

Abstract: The panel (10) has a rigid foam layer (12) of synthetic organic polymeric foam, a protective weathering layer (14) of thermoplastic sheet material and a generally flexible backer layer (16) of stereoreticulate material interposed between the foam and weathering layers. Interstices (30) of the backer layer (16) adjacent the foam layer (12) are filled with the resin of the foam layer (12) providing a physical bond and a protective substrate (32) for the foam layer. The weathering layer (14) may be adhered to the backer layer (34) by application of heat.
