A porcelain roof tile installing system that comprises: a roof tile having a porcelain body provided with an attachment hole; a nail for being inserted into the attachment hole of the roof tile thereby installing the roof tile to a roof structure; a nail gun for pushing the nail into the attachment hole; wherein the nail gun has a centering element configured to be coupled with the attachment hole.

A metal shingle having a body with left, right, top and bottom parts. The body is substantially planar and rectangular and has a front, a rear, left and right sides, a top and a bottom. The left and right parts extend from the left and right side respectively. One of the left and right parts is folded over the front and the other is folded over the bottom. The top and bottom parts extend from the top and bottom respectively. One of the top and bottom parts is folded over the front and the other is folded over the bottom. In use, the shingles are positioned in each of side-to-side and top-to-bottom abutting relation so that adjacent sides are interlocked. The body defining a hollow adjacent to one of the interlocking top and bottom parts.

The invention relates to a device (10) for fastening facade elements (40) with a plate (12) which, when fastened, extends in the vertical direction (z-direction) in a length b and in the horizontal direction (y-direction) and can be fastened to a house wall or a substructure (14), the plate (12) at its lower end having a profile chamber (16) which is square in section in the xy direction and has four side walls a, b1, c and d of different lengths, which are located in horizontal direction, where the side wall b1 of the profile chamber (16) is part of the plate (12) and the angle between the sides a and b1 is the only right angle in the square profile chamber (16), the angle between the side walls b and c is an obtuse angle, the length of the side wall c is shorter than the length of the side wall a and in the side wall b1 an indentation (17) is provided

A fastener plate for use in coupling an underlayment to a roof surface is disclosed. In use, the fastener plate is arranged and configured to enable subsequently applied liquid coatings to flow through a top surface of the fastener plate and into one or more cavities so that the liquid coating seals any openings created by introduction of the fastener. In one embodiment, the fastener plate may include a top surface, a bottom surface, a fastener opening for receiving a fastener, a plurality of openings formed in the top surface, and one or more cavities positioned between the top surface and the bottom surface, the one or more cavities being in fluid communication with the plurality of openings so that the liquid coating can flow through the plurality of openings formed in the top surface and into the one or more cavities to seal any voids created by the fastener.

Building integrated photovoltaic (BIPV) systems provide for solar panel arrays with improved aesthetics and efficiency that can replace conventional roof structures. BIPV mounting systems described herein allow for improved versatility and ease of installation as compared to conventional approaches. Such BIPV mounting systems can include photovoltaic (PV) roof tiles with separate mechanical coupling features and electrical contact portions for use with tile connectors having both mechanical and electrical coupling features. Such PV tiles can be mechanically and electrically coupled in series through the tile connectors without requiring wire bussing between adjacent PV roof tiles and the tile connectors can be slidable within a batten bracket to easily accommodate PV roof tiles of differing dimensions.

A roof tile comprising a ceramic body and a reinforcing element attached to a lower surface of the ceramic body.

A roofing system features a plurality of roofing sheets each having an outer perimeter of which two opposing perimeter edges respectively define a fastening edge and a hooking edge. One or more fastening holes penetrate the sheet near the fastening edge. At the hooking edge, the sheet is bent under itself to form a hooking portion reaching back toward the fastening edge. A plurality of hold-downs are placed atop a first row of roofing sheets near the fastening edges thereof, and have apertures aligned with the fastening holes of the roofing sheets, through which the hold-downs are fastened to the a roof deck. The hooking edges of a next row of roofing sheets hook to the affixed hold-downs of the first row, thus coupling the two rows of sheets together and concealing the first row's fastened connection to the roof deck beneath the second row.

Tile fixing devices, tile mounting methods, and roofs, such as those associated with solar tiles, are provided. For example, tile fixing devices related to the technical field of photovoltaic power generation are provided. In one illustrative implementation, a tile fixing device may include: a tile hook which is provided thereon with a fixing piece configured to cooperate with the mounting hole of the tile, as well as a positioning structure configured to limit the tile batten. Various tile mounting methods and roofs are also disclosed.

Exemplary systems and methods allow for enhanced energy performance of buildings, for example hybrid roof systems. The system may utilize a material having a porous water-retaining substrate and a high albedo coating. The high albedo coating may be disposed on the outer surface of the porous water-retaining substrate.

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 modules having the appearance of a plurality of roofing tiles that each have photovoltaic cells. Each photovoltaic module may include a metal backer, photovoltaic cells, and light transmissive top sheets adhered to both the metal backer and the photovoltaic cells. BIPV systems can also include non-photovoltaic modules that appear similar to photovoltaic modules, but do not collect solar energy.
