Interlocking laminated structural roofing panels have a lightweight foamed core sandwiched between outer and inner layers of materials such as wood, polymer materials, fire resistant and/or waterproof membranes, and metal layers. At least one layer is a self-gripping metal sheet that grips and bonds mechanically to adjacent layers such as wood layers. A self-gripping metal sheet may be used on both sides of the roofing panels to form a panel that is strong, structurally robust, and able to span between relatively widely spaced roof rafters with little or no mid-span support. Interlocking features along the edges of the panels interlock adjacent panels together to form a strong monolithic roof covering for a roof.

Load support structures for mounting a load atop a raised rib metal panel roof make use of relatively small, inexpensive, and easy-to-make adapter plugs as interfaces between the raised ribs and one or more component pieces or members of the load support structure, such as an upper diverter or a lower closure member. The adapter plug has an inner surface and an outer surface, the inner surface having an inner profile substantially matching or conforming to some or all of the profile of a particular style of rib profile. The outer surface of the adapter plug has a standardized shape, some or all of which is made to conform to an upper diverter, lower closure, and/or other component member of the load support structure.

Roofing panels with water shedding features may be installed on the roof of a house or other structure in lieu of or as an underlayment for traditional roofing materials. The water shedding features can be built into a base of the roofing panels, as part of a frame for the roofing panels, or formed as part of a waterproofing layer applied to the base of the roofing panels, or which can be configured as a roofing panel. The roofing panels also can be installed in overlapping courses along a roof with water shedding features applied thereto or incorporated along one or more peripheral edges. The water shedding features of adjacent roofing panels will collect and divert water away from the upper surfaces and/or away from headlap and/or sidelap joints defined between the roofing panels.

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 method of roofing a bare roof deck includes applying asphalt shingles and metal flashings to a wood deck of a roof. The flashings applied are edge drip for edges and gable ends, metal valleys, and step flashing for wall to roof junctions. Asphalt capping of ridges or hips are applied. Metal panels overtop of existing asphalt roof are applied thereby creating a metal overlay configured such that substantially all of the asphalt shingles are covered with a metal panel for preventing further degradation of asphalt components by shielding from sunlight, UV rays, excessive moisture, snow, wind, ice, and fire. No further flashings are installed thereby the metal panel overlay is configured to create a semi-watertight seal such that the metal panel overlay together with the asphalt roof is adapted to create a watertight seal.

The invention provides a system for installing a load on a metal panel roof, the system comprising a rail and closure structure adapted to be supported by ribs defined by the roof panels, and a load adapted to be supported on the rail and closure structure. In some embodiments, standing seams on ribs, and side rails on the rail and closure structure, extend parallel to each other, and optionally parallel to opposing sides of a hole in the roof. In some embodiments, substantially all of a downwardly-directed force of the load passes downwardly through the rail and closure structure to the ribs, and from the ribs to underlying structural members of the building.

A wall/roof panel includes (a) a faade 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 faade.

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.
