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.

An integrated joint sealing system that is incorporated into the edges of a sheathing panel, which also may have a factory bonded weather resistive barrier. The edges of each panel are configured as a shiplap joint, or similarly functioning joint, that is present as either an overlap or underlap on each of the four panel edges. The arrangement of the joints are such that one edge will have an overlap and the opposite edge will have an underlap. A flexible gasket material (or materials) is factory applied to one or both sides (underlap and/or overlap) of the shiplap joint. This flexible gasket material, when overlapped with adjacent shiplap panels, provides a weather resistive seal to limit both water and air penetration.

A roofing system that is configured to be superposed upon an existing roof and further be mechanically coupled to the purlins of the structure on which the roofing system is being installed. The present invention includes a plurality of support spacing members wherein the support spacing members are axially aligned with purlins of the structure and mechanically secured thereto. The support spacing members include a center portion that is elevated with respect to the existing roof. A plurality of roof panel members are provided wherein the roof panel members further include longitudinal edge formations. The longitudinal edge formations of the roof panel are configured to couple with longitudinal clip members in order to operably couple adjacent roof panel members during installation of the roofing system of the present invention. The longitudinal clip members are mateably shaped to facilitate coupling with the roof panel members.

A weight-bearing system for hanging items from the roof structure of a metal building is disclosed. The system includes a purlin with at least one flange, a span aperture in the vertical span of the purlin, a clip that attaches to the purlin using the span aperture, and a fastener on the clip for transferring weight applied to the fastener to the clip and to the vertical span of said purlin.

A wall/roof panel includes (a) a façade that has (i) an outer surface that defines a front surface of the panel and (ii) a rear surface and (b) a structural element connected to and supporting the façade.

A solar roof of a building includes a plurality of solar panels removably coupled to a roof of the building such that a first solar panel of the plurality of solar panels is configured to be removed from the roof without removing an adjacent solar panel.

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 method is provided for forming an adhered membrane roof system that meets Factory Mutual (FM) 4470/4474 standards for wind uplift. The method comprises applying a bond adhesive to a substrate on a roof to form an adhesive layer and applying a membrane directly to the adhesive layer. The bond adhesive includes a moisture-curable polymer.
