Abstract: The roof system is formed of a corrugated sheet of material anchored to a roof beam, a mineral board anchored to the peaks of the corrugated sheet having a moisture barrier, at least one layer of insulating material interposed between the mineral board and the corrugated sheet, and standing seam metal roof panels anchored to the mineral board. A staggered anchoring system is provided which eliminates thermal shorts from the outside of the roof to the inside roof beams.

Abstract: A composite roof/roof deck assembly and method of installation wherein a roof covering of polymeric sheet material is adhered to an underlying gypsum board roof substrate with a water based polymeric adhesive. The gypsum board has a porous fibrous glass matte facing to enhance bonding between the water-based adhesive and the gypsum board.

Abstract: A building roof, having an optimum strength to weight ratio, and method of constructing the roof wherein a horizontally disposed roof deck assembly particularly adapted to provide diaphragm shear strength and shear stiffness is formed comprising: a sheet (12) of steel corrugated material, a sheet (14) of optional insulation material, and a sheet (16) of rigid substrate material mechanically fastened together by screws (18). The sheet (12) of corrugated material is welded to purlins (20) by elongated welds (40) formed to resist rotation of the corrugated sheet (12) in a horizontal plane. The screws (18) extend through the rigid substrate (16) and through rigids (11) on the upper side of the corrugated sheet (12) to form a truss-like structure extending generally parallel to the purlins (20). Weld washers 30 having elongated slots (35) are used to secure high tensile strength symmetrically corrugated steel (12) having a thickness in a range of 0.0144 inch to 0.
