Roofing shingles are disclosed that are capable of self-adhering to a roof deck or underlayment and/or other roofing shingles and that require few or no mechanical fasteners to remain attached to the roof. By appropriate positioning of sealant lines on the shingle, direct adhesion between the shingle and the roof deck or underlayment and/or other roofing shingles can be achieved. If the shingle is laminated, the layers may be mechanically attached with indentations in the common bond area. The nail zone of the shingle may be visually indicated with fines and/or one or more paint lines. A roofing system comprising a plurality of courses of the shingles is also disclosed.

A system includes a plurality of photovoltaic shingles installed on a roof deck, each of the shingles having a first layer including a head lap portion, and a second layer including at least one solar cell. A first photovoltaic shingle overlays at least a part of the head lap portion of a second photovoltaic shingle. The system includes at least one wireway installed proximate to a first end of at least the first photovoltaic shingle.

The present disclosure provides a new design for an injection molded roof panel with multiple improvements. The panel is made from PVC-like materials via injection molding with a large standard size. It comprises laterally and longitudinally sloped watercourses and arches. A tongue at the front connects to a vertically adjacent panel's rear upper interlocking member. Interlocks at the lateral ends of the panel connect one panel to another horizontally adjacent panel. Condensed water ridges underneath the panel drain condensation to the panel's front, where it is drained with angled weep holes on the tongue. The upper surface has a non-smooth low-noise texture to prevent slips/falls and reduce noise. The roof panel is secured onto roof sheathing with nail flanges with screw holes/bosses. The design achieves improved water drainage, increased installation security and speed, improved wind resistance, increased personnel safety, reduced noise, lighter weight, lower cost, and improved lifespan.

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 shingle comprises an overlay, an underlay, and a height increasing material disposed between the overlay and the underlay. The height increasing material includes a first adhesive adhered to the overlay, height increasing granules adhered to the first adhesive, and a second adhesive adhered to the height increasing granules and the underlay. The height increasing material can extend along front ends of tab portions of the overlay, along front cutout edges that extend between tab portions of the overlay, or both.

Roofing panels for concealing a biocidal source are described. In embodiments, the roofing panels include a body having as top side, a bottom side parallel with the top side, a front edge, a rear edge, and a left edge. The roofing panels may further include a first sidewall, a second sidewall, and one or more standoffs. The first and second sidewalls may have a tapered sidewall height that provides a gap between the body of the roofing panel and underlying material. The roofing panel may be installed over a biocidal source on a roof, concealing the biocidal source from view while still allowing liquid (e.g., water) to flow over the biocidal source.

This invention, in embodiments, relates to a roofing system comprising (a) a roofing substrate having a roofing surface, (b) a first roofing tile overlying the roofing surface, the first roofing tile having a front surface, a back surface, a top edge, and a bottom edge, and (c) a second roofing tile overlying the first roofing tile, the second roofing tile having a front surface, a back surface, a top edge, and a bottom edge. At least one sealant line is applied to (i) the back surface of the second roofing tile in an area that overlays the first roofing tile, (ii) the front surface of the first roofing tile in an area in which the second roofing tile overlays the first roofing tile, or (iii) both (i) and (ii). The at least one sealant line is configured to adhere the second roofing tile to the first roofing tile.

A shingle coating asphalt composition is provided that is produced from a paving grade asphalt. The asphalt composition comprises a paving-grade asphalt that has been modified with one or more polymer additives; and a secondary additive comprising one or more of a viscosity reducing agent, a wax, a salt of a fatty acid ester, and an amide of a fatty acid. The shingle coating asphalt coating composition is used to make a shingle. The shingle includes a substrate, the asphalt, and roofing granules.

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 solar energy roof tile, thermally and/or electrically conductively connected to an adjacent solar energy roof tile, includes a lower face for placing on at least some regions of a roof construction, an upper face opposite the lower face formed at least in some regions by a solar energy utilisation module, two opposite lateral walls, a rear face connecting the lateral walls, and a front face opposite the rear face that connects the lateral walls. The two lateral walls, the rear face and front face together connect the lower and upper faces, such that a cavity is formed between the two lateral walls, the rear face, front face, and lower and upper faces. The lower face has, in the region of the front face, a lower opening for providing access. The upper face has, in the region of the rear face, an upper opening for providing access into the cavity.
