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 roofing system including a plurality of roofing panels that can be releasably secured to rafters or other supports of the roof by connectors. In embodiments, the connectors can include first and second connectors, each of which can include a plate with a projection extending therefrom, and with the plates defining flanges on each side of the projection. The plates of the first and second connectors are configured to seat on and at least partially extend along one of the rafters of the roof structure and along exterior facing surfaces of adjacent ones of the roofing panels to releasably secure the roofing panels to the rafters.

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 fastening arrangement including a grommet, which is configured as a substantially cylindrical sleeve with a head part, with a hollow-cylindrical shaft and with a conical tip, and also a fastener and a nut, for example made of plastic, which is fitted on the first threaded portion of the fastener. The fastener has two threaded portions, wherein one threaded portion is configured as a right-hand thread and the other threaded portion is configured as a left-hand thread (or vice versa). Moreover, the invention comprises a mounting method for such a fastening arrangement, in which the setting operation (anchoring of the fastener, adjustment of the sheath) can be managed in one step without changing the driving direction of the setting tool.

A ventilated solar panel system mounted on a roof of a building (1), comprising a plurality of joists (12, 112) arranged substantially normal to an upper ridge (14) of the roof, and extending from the upper ridge (14) to a lower region of the roof, and a set of rectangular solar panels (2, 13), arranged on and supported by the joists (12, 112). The system further comprises a set of electrical fans (25), each fan (25) being arranged in the lower region of the roof and being aligned with one of the joists (12, 112), wherein each fan (25) is configured to create a flow of air towards the ridge (14), and wherein each joist (12, 112), in an end facing one of the fans (25), is formed with a dividing edge (32, 132) configured to divide the flow of air into two sub-flows (26a, 26b), a first sub-flow (26a), directed to a first side of the joist (12, 112), and a second sub-flow (26b) directed to a second side of the joist (12, 112), opposite to the first side.

Support members for a roof system are provided to allow for positioning panels of a roof apart from building members so that building components, such as insulation may be placed between the roof panels and the building members. The support members may be utilized in new buildings or to retrofit existing buildings. Each of the support members may comprise a single support member that has a base portion operatively coupled to an offset portion that is operatively coupled to an upper portion. One or more channels may be provided in the base portion, offset portion, and/or the upper portion to provide structural support and to allow the support members to be operatively coupled to each other and other building members without the need for additional components.
