A self-sealing fastener for installation of roofing materials for creating a substantially watertight seal around fastener penetrations where roofing materials or panels are affixed to an underlying roof deck by the fasteners. Also disclosed is a method for installing the self-sealing fastener for attachment of roofing materials to an underlying roof deck with the penetrations areas or holes created by the fasteners being substantially sealed against water penetration.

A roof system includes a roof deck, a weighted cover board disposed upwardly adjacent the roof deck and a plurality of fasteners coupling the weighted cover board to the roof deck.

A roof deck (20) has plurality of insulated panels (22) secured together by a first plurality of fasteners (54) along their longitudinal edges (28, 29). Additionally, the panels (22) are secured by a second plurality of fasteners (56), transverse to the longitudinal axis (26), to a framework (18). A plurality of washers (60) disperse the force of the second plurality of fasteners (56). The plurality of washers (60) are secured to each of the second plurality of fasteners (56). A membrane (24) covers the roof deck (20).

A roof pan with raised ridges along lateral edges, where the raised ridges of one pan cooperate raised ridges of another pan to prevent water movement. A formed edge that is offset from the roof surface when the pan is installed on the roof allows a flashing to slide under the formed edge when the roof pan is installed on the roof surface.

A shingle assembly for installation on a roof structure is provided. The shingle assembly can include an insulative substrate, a surface sheet coupled to and extending across a substantial portion of the insulative substrate, and a hook-and-loop fastening system comprising a hook portion and a loop portion. The hook portion or the loop portion can be coupled to and extend along the insulative substrate adjacent the surface sheet. The other of the hook portion or the loop portion can be coupled to and extend along the surface sheet. The hook portion can be configured to mate with a loop portion of a first adjoining shingle assembly and the loop portion can be configured to mate with a hook portion of a second adjoining shingle assembly.
