A shingle assembly for installation on a roof structure is provided. The shingle assembly can include an insulative substrate, a surface sheet coupled to and extending across a substantial portion of the insulative substrate, and a hook-and-loop fastening system comprising a hook portion and a loop portion. The hook portion or the loop portion can be coupled to and extend along the insulative substrate adjacent the surface sheet. The other of the hook portion or the loop portion can be coupled to and extend along the surface sheet. The hook portion can be configured to mate with a loop portion of a first adjoining shingle assembly and the loop portion can be configured to mate with a hook portion of a second adjoining shingle assembly.

An impact resistant roofing shingle comprising an upper shingle layer; a lower shingle layer laminated to said upper shingle layer underneath said tab portion of said upper shingle layer; wherein each of the upper shingle layer and the lower shingle layer comprise a mat, an upper asphalt coating layer applied to an exposed side of the mat, a lower asphalt coating layer applied to an unexposed side of the mat, a granular coating applied to the upper asphalt coating layer opposite the mat, and a fabric reinforcing layer applied to the lower asphalt coating layer opposite the mat. In one embodiment, the roofing shingle may also include the fabric reinforcing layer covering the entire area of each mat. The roofing shingle may have a recessed area of the exposed side of the overlay layer that aligns with the overlap of the overlay and underlay layers.

A photovoltaic element comprising: (a) a photovoltaic assembly; (b) a shingle portion connected to the photovoltaic assembly, the shingle portion including: (i) one or more flexible regions and (ii) one or more attachment regions; wherein the one or more attachment regions connect the photovoltaic element to a structure and the one or more flexible regions are flexed so that all or a portion of the attachment regions are located below the shingle portion; and wherein the one or more flexible regions, the one or more attachment regions, or both include one more drainage elements.

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 laminated composition shingle includes a first sheet having a first mineral granule surface and a first rectangular shape without tab cut-outs laminated with a second sheet having a second mineral granule surface. The second sheet has tab cut-outs along only one longer edge of the second sheet. The laminated composition shingle has a shingle width and an exposure width perpendicular to the long edges and a first width that is twice the exposure width. The shingle width is the first width plus 2 inches (51 mm). The tab cut-outs have a tab width in the direction of the shingle width less than the exposure width minus of an inch (3 mm).
