Abstract: A system for blocking an edge of a building roof structure, e.g., roof structures of cementitious material poured over a corrugated deck or roof structures of rigid insulative panels supported on a corrugated deck, comprises an elongate U-shaped base member for affixation to the deck along the roof edge, an elongate cover member of inverted U-shape for affixation over the base member, the base and cover members being made of galvanized steel or other suitable non-wood material and, as assembled together, forming an auxiliary perimeter structure on the roof structure for border containment of the roofing material.

Abstract: A coping or fascia assembly for a flat or raised building roof edge, parapet wall, cant dam, gravel stop or the like resiliently maintains the coping or fascia assembly in a tight-fitting interlocking installation and has a locator member beneath the coping or fascia cap for maintaining at least a portion of the outer coping cap in a predetermined cross-sectional shape and in an accurate alignment between adjacent sections of the coping cap. The locator member has a free-floating side edge in order to allow it to yield during installation of the coping or fascia cap. The preferred triangular locator member is generally symmetrical with respect to a line normal to the face of the wall, dam stop or other raised roof protrusion. The coping assembly is quicker, easier, and less costly to install than prior such structures and provides enhanced protection for interior or underlying components or structures.

Abstract: A roofing system having preferred metallic roofing panels overlying a roof structure or a substrate (such as a waterproof membrane) includes a mat of loosely-woven ventilation mesh material between the panels and the roof structure or substrate in order to provide proper ventilation, thus minimizing corrosion resulting from condensed moisture. The mesh is preferably composed of an extruded thermosetting plastic material.

Abstract: A coping assembly is disclosed for a parapet wall on a building structure that can accommodate varying or inconsistent wall widths, with the parapet wall having generally vertical inner and outer vertical surfaces interconnected by a generally horizontal upper surface. Coping assemblies according to the present invention include a preferred resilient clip member, a clip attachment device for attaching the clip member to the parapet wall, a fascia member, a top plate member, and a top plate anchoring device for anchoring the top plate to the parapet wall. The fascia member and the top plate member have overlapping or telescoping portions that provide for the feature by which various wall widths or thicknesses can be accommodated.
