A method of forming a leakproof pitched wall or roof section with the use of solar panels includes arranging the solar panels in rows so that at least one panel on the second row is offset upwardly relative to at least one panel on the first row. Seals are provided to prevent the leakage of liquid through the pitched wall or roof section formed by the solar panels.

An industrial roof panel includes a projection and a complementary wing at opposite sides. The projection has a recess configured for clamping the panel to a second neighboring panel using a fastener such that the panel is supported by the second neighboring panel for reduced buckling under downward load. A modular panel system includes first and second mutually juxtaposed panels, each supported by purlins of a building structure extending along a width of the panels. The second panel has an undercut extending along a length of the panel on a distal side thereof. The first panel has an integral wing-type female coupler extending along a length of the first panel and overlaying an upward projection of the second panel, to which it is secured using fasteners and bolts.

At least first and second rows of panels may be mounted onto, or to form, at least part of a pitched roof, wall or other structure by mounting a panel support framework onto an underlying structure and arranging the panels so that each panel on the second row is offset upwardly relative to each panel on the first row in a stepped fashion.

A connector arrangement for a flashing assembly for use in a roof window arrangement is disclosed. It comprises a base connector element, an elevation element and a top connector element. Both connector elements have a gutter in their exterior side, and the gutter is open at one end so that water can drain out of it. An attachment section on the interior side of the base connector element is configured for being attached to a bracket used for connecting a roof window to a load-bearing structure, and the elevation element supports the top connector element so that it is positioned above the base connector element. In the mounted state the second end of the top connector element is arranged above the gutter of the base connector element and their length directions extend substantially in parallel to each other. A method for weather proofing a roof window arrangement is also disclosed.

A roof apparatus provides a uniquely configured clip assembly or interface that connects upper roof panels to under supporting beams. In one embodiment, the clip or interface provides multidirectional movement of roof panels to under support beams. In one embodiment, a specially configured U-beam can be an understructure beam that carries utilities such as piping or electricity.

A clip for electrically bonding a pair of adjacently-disposed metal panels is disclosed. One embodiment entails such a clip (104) including a first clip member (112) and an oppositely disposed second clip member (116). The surface (114) of the first clip member (112) that faces the second clip member (116) includes at least one grounding projection (128), while the surface (118) of the second clip member (116) that faces the first clip member (112) also includes at least one grounding projection (128). The clip (104) may be installed on a standing seam (102) of a panel assembly (100), with its first clip member (112) engaging one of the metal panels 82″ that define this stand seam (102) and with its second clip member (116) engaging the other of the metal panels 82″ that define this same standing seam (102).

In a roofing structure, two roof panels with different slopes and lengths are positioned back-to-back, the vertical back walls of the panels having a uniform height. The seam between the two differently-sloped panels are connected by a ridge cap set at a uniform height. The ridge cap covers the seam, extending on both sides to a distance from the back walls of the roof panels sufficient to create a capillary break therefrom (preventing moisture migration) and then downwards and slightly towards the back walls of the roof panels, thereby using gravity to direct the water into the downward sloping roof panels.
