This invention is a hip and ridge liner for a roof on a building. It is a waterproof and weather proof barrier that is installed on top of a hip line or a ridge line on a roof. Hip and ridge shingles are then installed on top of the hip and ridge liner. Embodiments of this invention include a plurality of external tabs which function to securely retain the hip and ridge shingles and keep them in place for many years. Other embodiments of this invention include a plurality of internal tabs which function to securely retain the hip and ridge shingles and keep them in place for many years. Other embodiments of this invention include a plurality of shingle retaining clips which function to securely retain the hip and ridge shingles and keep them in place for many years.

A system includes a plurality of photovoltaic modules, each having a mat with an edge and a spacer with an edge, the edge of the mat being attached to the edge of the spacer. The spacer includes a plurality of support members and a solar module mounted to the support members. Each of the support members includes a ledge. The solar module and the ledge form a space therebetween. The space is sized and shaped to receive an edge of a solar module of another of the photovoltaic modules. The spacer of one of the photovoltaic modules overlays the mat of another of the photovoltaic modules.

A tile system comprises at least two tiles and at least one elongate support. Each tile is generally rectangular in shape and has a first edge, and a second edge, the second edge being generally opposite the first edge. Each elongate support has an attachment portion and a support portion. Proximate the first edge each tile is provided with a groove, the groove being configured to receive the support portion of one of the elongate supports and a portion of an adjacent tile proximate its second edge.

A roofing system for forming a roof includes a plurality of tiles. Each tile has a frame at a perimeter of the tile, and the frame includes an upstream element, an opposed downstream element, and opposed first and second side elements, thereby bounding a central panel area. Each tile further includes a side trim, a batten, and a ridge cap. When the tiles, side trim, batten, and ridge cap are arranged to form a roof, the batten is secured at a lower edge of the roof and directed upward to receive the downstream elements of the tiles, the side trim is secured at a side edge of the roof and directed laterally to receive one of the first and second side elements of the tiles, and the ridge cap is secured at a ridge of the roof and directed downward to lap over the upstream elements of the tiles.

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.
