A system and method of roofing. The present invention includes a fabric sheet having an upper surface and a lower surface. The upper surface includes one of a hook and loop fastener and the lower surface is configured to be attached to a roof decking. The present invention further includes a plurality of tiles each having an upper edge, a lower edge, a top surface, and a bottom surface. The other of the hook and loop fastener is attached to the bottom surface. The plurality of tiles are releasably attached to the upper surface of the fabric sheet via the hook and loop fasteners.

Disclosed is a roofing underlayment providing mechanical and electrical connection for solar shingles that includes a water-impervious membrane adapted to be attached to a roof. The underlayment also includes a mechanical attachment member configured to mechanically attach a solar shingle to the roof, as well as an electrical conductor having an electrical first portion of which is embedded within the membrane, having an electrical second portion which is configured to electrically connect to a solar shingle, and having an electrical third portion which is configured to electrically connect to an electrical circuit. An air gap is provided that allows for air flow below the solar shingles. The air gap comprises a space between a bottom surface of the solar shingles and a bottom surface of the membrane.

A roof integrated photovoltaic (RIPV) system has a plurality of solar tiles that are mounted to a roof. The tiles may be mounted using a metal batten and hanger system or some other attachment system. Each tile has an electrical edge junction extending rearwardly from its top edge. The edge junction is coextensive with or contains the plane of the solar tile and may be slightly thicker than the solar tile. Sockets on opposed ends of the edge junction receive plugs of electrical cables for interconnecting the array of solar tiles together electrically. The edge junctions provide for a low profile installation that mimics the appearance of a traditional roofing tile such as a slate tile. The slightly thicker edge junctions may raise solar tiles of one course above the surfaces of solar tiles of a next lower course to provide ventilation for the RIPV array and to provide accommodating space for system wiring.

The invention is an electrical and mechanical roof underlayment which provides electrical and mechanical connection of solar shingles to a roof. The underlayment simplifies the installation of solar shingles allowing the shingles to be installed and connected together in the same step. The underlayment includes a membrane which has embedded electrical conductors and electrical connectors that provides an electrical connecting system extending to an electrical circuit. The membrane further has embedded mechanical members with mechanical connectors that secure the shingles to the membrane. The membrane is structurally attached to a roof surface. The structural attachment may be an adhesive attachment. Solar shingles are connected to the membrane by an integral clasping mechanism that mechanically and electrically connects the shingles to the membrane. No external wiring, connectors or devices are required to make the electrical connection between the shingles and the membrane. Contacts are integral and embedded into each individual shingle.

A metal wall material 1 according to the present invention comprises: a front substrate 10 made of a metal sheet, the front substrate 10 comprising a body portion 100 formed into a box shape; a back substrate 11 arranged on a back side of the front substrate 10 so as to cover an opening of the body portion 100; and a core material 12 filled between the body portion 100 and the back substrate 11, the metal wall material 1 being tightened to a wall base by driving at least one tightening member into the body portion 100, wherein a top plate portion 101 of the body portion 100 comprises at least one protruding rib 3 comprised of at least one protrusion 30 disposed along a side of a polygon or along a circle, and wherein the metal wall material 1 is configured such that the tightening member is driven into an inner region 3a of the protruding rib 3.

A shingle support according to this invention is easily aligned on and affixed to roof rafters. Once affixed, the shingle support provides a support to roofing shingles, to facilitate installation. It also provides the function of creating a protective terminus to each shingle to prevent lifting and damage by wind. As a result of use of the shingle support according to this invention, roofers are provided with an apparatus, kit, system and method for roof shingle installation superior to that currently available. In addition, the resulting roof shingle installation is more robust than known roof shingle installations.

A roof tile clip (1) for securing a lateral edge (3) of a lower portion of a roof tile (2) to a batten (5), the lower portion of the roof tile (2) rests on an upper portion of a below roof tile (2), which in turn rests on the batten (5), the roof tile clip (1) comprises a hook (6) for hooking over the lateral edge (3) of the roof tile (2), a securing device (7) for securing the clip (1) to the batten (5), and a shaft (8) between the hook (6) and the securing device (7), wherein the securing device comprises a retainer (7) slidable in a longitudinal direction (9) of the batten (5).
