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.

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 connector element for a flashing assembly for use in a roof window arrangement is disclosed. The exterior side of the connector element comprises a gutter with two longitudinal edges configured for engagement with an engagement section of a flashing member. A connecting section is configured for being connected to a bracket used for connecting a roof window to a load-bearing structure of the roof structure. The connector element is configured for being arranged with a first end at an outer side of a bottom frame member of a first roof window and a second end at a second roof window. At least one attachment element is provided on an end surface at the second end, said attachment element being adapted for engagement with a supporting element of a flashing assembly. A method for weather proofing a roof window arrangement is also disclosed.

An apparatus is contemplated for creating a structure which simultaneously serves as both a building element and a photovoltaic power source. Components of the invention interface with modules which comprise photovoltaic solar panels. When used collectively, these modules are contemplated as comprising a replacement for a roof or other building component. When the present invention is used, a roof or other building component can be created without the need for a separate underlayment, and without the need for tiles or another outer waterproofing layer. This setup results in power generation, cost savings, and environmental advantages Additionally, embodiments of the invention comprise fixed stop elements which ensure correct placement of modules on a frame assembly. The invention could also include other elements, including water gutters, grab steps which facilitate access, and specially positioned border covers to protect and aesthetically cover wired regions of solar modules.

The invention relates to a fastening system for large-area roof coverings or wall claddings.

The object is to create a fastening system which is structurally simple, consists of few parts, is fast to install and is suitable for high negative wind loads.

Fastening is achieved within two upwardly projecting longitudinal ribs 2, which are formed by upwardly projecting sheet metal flanks 11. These sheet metal flanks 11 are bent up and provided with projections 13. According to the invention, T-shaped base bars 3 are disposed and fastened within the upwardly projecting longitudinal ribs 2, either continuously or only in some places. The horizontal wide limb of the T-shaped base bars 3, designated as foot limb 5, can be disposed upwardly or downwardly. The T-shaped base bar 3 has recesses 6 formed left and right in the vertical limb of the T-shaped base bar 3 and reaching into the foot limbs 5. Specially formed projections 13 of the sheet metal flanks 11 of the roof elements, sheet metal plates or sheet metal strips 1 engage in these recesses 6. These preformed projections 13 result in a form-fitting joint in conjunction with press plates 9 that can be disposed at or on the central limb 4. The press plates 9 are appropriately fastened with the base bar head 7 in a form-fitting manner or, for example, with screws. The press plates 9 are formed such that the press plates 9 span over the projections 13 of the sheet metal flanks 11 of the roof elements, sheet metal plates or sheet metal strips 1 positioned side by side. This creates a durable form-fitting joint by means of the T-shaped base bar 3 (or base element), central limb 4 and press plate 9. At the upper ends of the upwardly projecting lateral sheet metal flanks 11, the whole longitudinal rib is closed towards the top with a cover strip 12.

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.
