Abstract:
A horizontal roof deck assembly has a ribbed steel roof deck sufficiently strong to withstand specified gravity, uplift, and shear loads. Rigid substrate boards are positioned adjacent one another above the deck, defining end and side joints. End joints are parallel to and above a corresponding upper rib of the roof deck and are secured to the upper rib by compression disk fasteners spaced along the end joint. The side joints can be tongue and groove joints. Additional fasteners attach the substrate boards to the roof deck along the side joints, for wind uplift resistance, and for thermal movement resistance.

Claim (Index 18):
A method of retrofitting a substantially horizontal, pre-existing roof assembly having a corrugated steel deck defining a plurality of alternating upper and lower ribs, to create a non-composite strength roof assembly, the method comprising:\n removing pre-existing roof coverings and insulation from the roof deck, the roof deck having sufficient strength alone and without composite structural strength provided by attachment to other roofing layers to withstand predetermined gravity, diaphragm, wind uplift, and diaphragm shear loads on the roof assembly; positioning adjacent to one another a plurality of rigid substrate boards above the roof deck, the rigid substrate boards having opposed sides and opposed ends, with the rigid substrate boards defining end joints at adjacent ends and defining side joints at adjacent sides, the rigid substrate boards defining a generally flat upper surface; positioning each of the side joints to span across multiple upper ribs of the roof deck; positioning each of the end joints parallel to and above a corresponding upper rib of the roof deck; attaching the rigid substrate boards along each end joint to the corresponding upper rib of the roof deck with a plurality of end joint fasteners; and attaching the rigid substrate boards to the roof deck along the side joints using a plurality of spaced apart side joint fasteners; attaching a roof covering membrane to an upper surface defined by the rigid substrate boards by fully adhering the roof covering membrane to the upper surface of the rigid substrate boards; and minimizing relative movement of the rigid substrate boards at the joints between the rigid substrate boards using the side joint fasteners along the side joints between the rigid substrate boards and the compression disk fasteners positioned in the end joints between the rigid substrate boards.
