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.

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.

Some embodiments of the present disclosure relate to a roofing system. In some embodiments, the roofing system includes a first roofing material, wherein the first roofing material comprises a top surface and a bottom surface. In some embodiments, the top surface of the first roofing material comprises a nail zone with a plurality of fines. In some embodiments, the roofing system includes a second roofing material, wherein the second roofing material comprises a top surface and a bottom surface. In some embodiments, the bottom surface of the second roofing material comprises a plurality of fines. In some embodiments, the roofing system comprises and a patterned adhesive, which directly contacts at least a portion of the plurality of fines in the nail zone and at least a portion of the plurality of fines on the bottom surface of the second roofing material.

A roofing system and method, which includes elongate rain diverting devices for directing rainwater and snowmelt away from an underlying sheet material and roof deck, is provided. The system includes roofing tiles having strips of hook and loop fasteners (H&L strips) adhered to both faces. The rain diverting devices have an H&L strip adhered along a lower edge of both faces. As each new row of tiles is installed on the roof deck, the device is applied over an upper portion of the tiles, extending over and onto the sheet material above the tiles, and across the roof deck. As additional rows of tiles are installed, each device is releasably attached to underlying and overlying tiles by way of the H&L strips adhered to both the tiles and the device. The devices also allow for single lap tiling (less weight on roof deck) and for use of shorter tiles (saving material cost).

Shingles have self-seal strips with features that include sealant dashes or dots separated by drainage gaps. The self-seal strips are registered with each shingle so that the features are positioned at the same locations on each shingle. A method of making such shingles includes synchronizing the rotation of sealant applicator wheels with the shingle chop cutter so that cuts are made at repeated designated locations along the applied self-seal strips.

In various embodiments, a tile system for mounting structures to a roof may comprise a base assembly, a fastener, a seal, a flashing, and a mounting bracket. The fastener may be installable on the base assembly. The seal may be installable on the fastener. The flashing may be configured to replace a roof tile. Moreover, a protrusion may be field formed in the flashing during installation of the tile system by driving the fastener through the flashing in response to the base assembly being positioned on the roof surface. The bracket may be installable on the fastener and configured to compress the flashing against the seal and the base assembly.

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).

A lightweight interlocking metal roof system for installation onto a steep or inclined structure roof either directly over the roof decking material or over an existing shingle roofing system, with the metal roofing system installed from the roof ridgeline down to the drip edge of the roof gutter. Cooperating outwardly extending flanges and receiving pockets for capturing and interlocking the metal panels of the roofing system create an interlock between and among panel members with overlying edge ends configured to be resistant to lift up due to winds either across the roof or along the roof edges.

Roof tile for forming a roof covering, wherein the roof tile (1) comprises a ceramic body (8); wherein said ceramic body (8) is made of porcelain; and wherein the roof tile (1) further comprises a glaze coating (9), which is situated above said ceramic body (8).
