The present disclosure relates generally to roofing systems, for example, suitable for covering the roof of a house or other building. The present disclosure relates more particularly to a roofing system that includes a plurality of riser blocks disposed on a support surface. The riser blocks include a group that is aligned in a row. A batten extends along the row and is supported by the group of riser blocks. The batten includes a first clip portion. A group of roofing panels is disposed along the row and is supported by the batten. Further, each of the roofing panels of the group includes a front surface, a rear surface, and a second clip portion extending from the rear surface. The second clip portion is configured to engage the first clip portion of the batten so as to secure the roofing panels to the batten.

Battens for mounting on a building surface such as a roof are connected by bendable, lengthwise substantially inelastic connecting members, the length of each connecting member between adjacent pairs of the battens having a predetermined length corresponding to a predetermined batten separation. When deployed on the building surface, the batten separations and thus positions of the battens relative to each other are maintained substantially constant by the connecting members. When stowed, however, the battens lie against or immediately adjacent to each other with the connecting members extending outward from between adjacent ones of the battens. A user may deploy the batten arrangement for mounting by laying it in the stowed configuration on the building surface and pulling it into the deployed configuration.

A light steel roof truss with a structure of a double continuous beam includes structural beams (1) and structural columns (2). The structural beam (1) consists of a pair of continuous beams, and the structural column (2) is located between the two continuous beams through locating holes (4). Thereby the stability of a support structure of the roof truss is increased, and the supporting members of the roof truss can be connected conveniently.

A roof system includes a roof deck and a plurality of roof rafters supporting the roof deck. A thermal break is located between the deck and a first rafter of the plurality of rafters. The thermal break includes a break inner member contacting a first rafter exterior surface of the first rafter and a break outer member contacting a deck inner surface of the roof deck. The break inner member and the break outer member bound a thermal air break therebetween.

An improved roofing system including a batten assembly comprising support battens and clips. The clips are made of metal wire having one portion shaped to retain roof outer coverings and a further portion shaped to secure the clip to the batten by spring torsion force of part of the clip acting against the batten.

Roof brackets for attaching a structure such as a patio cover to a building, and methods for installing the brackets. The brackets have a saddle for receiving a support beam of the structure. The brackets can be attached to the building roof, but do not penetrate the roof substrate, thus preventing leakage and other structural problems. The roof brackets comprise a plate that is installed between the roof substrate and the shingles or tile on the roof. The brackets are available in different configurations compatible with standard roof pitches for easy installation. One roof bracket has a riser so that the saddle is lifted above the roof. Another roof bracket is configured so that when installed the saddle is located beyond the edge of the roof. Other brackets can be attached to the rafters under the roof, are available in different configurations depending on standard roof pitch, and they are configured to extend below and outward from the fascia. Any of these brackets are available in versions which are adjustable by the installer to provide a level saddle even in situations where the roof does not have a standard pitch, whether by design or due to inaccurate installation.

A roof integrated photovoltaic mounting system includes a plurality of aluminum rails mountable in horizontal spaced relationship on a roof for receiving courses of photovoltaic panels or photovoltaic tiles. The PV panels or tiles have an extruded attachment feature along their forward edge portions that defines a downwardly projecting forwardly facing hook. Panels or tiles are installed by placing each panel or tile on a pair of rails and sliding the panel or tile down until its forward facing hook engages beneath a rear facing tongue on a rail below. A PV panel or tile in a next lower course is installed by slipping its rear edge beneath the forward edge of a panel or tile in a next higher course. The panel is then hinged down about its rear edge until its forward edge portion engages a support rail below. The panel is then slid down until the hook of its attachment fixture engages beneath the tongue of the downslope rail. When the entire array is installed in this manner, the forward edges of the panels are held down by the hook and tongue engagements and the rear edges are held down by being underneath the forward edges of panels in a next higher course. The procedure is reversed to remove a panel for servicing or replacement. In the case of solar glass tiles, water troughs are installed on the rails underlying abutting ends of tiles in a course to collect rainwater and direct it onto the upper surface of a tile in a next lower course.

This invention is an envelope-structure interface, enabling the use of exterior insulation and pressure-equalized cladding with a post-frame structure. The present invention includes the following interface details: a continuous roof-to-wall water, vapor, and air impermeable weather barrier that is fully adhered to sheathing exterior of framing, girts, and purlins; continuous roof-to-wall insulation exterior of weather barrier that is mechanically fastened back to the post-frame structure; and removal of the requirement for an interior finish material in a conditioned post-frame building. The invention brings superior envelope performance to the structural and material efficiency, rapid rate of construction, and affordability of post-frame techniques.

Building integrated photovoltaic (BIPV) systems provide for solar panel arrays that can be aesthetically pleasing to an observer. BIPV systems can be incorporated as part of roof surfaces as built into the structure of the roof, particularly as photovoltaic tiles. Each photovoltaic module may comprise an inner sheet, an outer sheet, photovoltaic cells, and a bracket. When installed the bracket may be covered by up-roof tiles, giving the overall roof a uniform appearance.
