A system includes a plurality of roofing shingles installed on a roof deck. Each of the roofing shingles includes first and second ends, first and second edges, a head lap, a reveal portion, a first side lap at the first end, and a second side lap at the second end. The second side lap includes a first surface, which has an adhesive. The first side lap of a first one of the roofing shingles overlays and is attached to the second side lap of a second one of the roofing shingles to form a sealed portion between the head lap of the first one of the roofing shingles and the head lap of the second one of the roofing shingles.

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.

A multi-layer cap shingle for installation along a ridge, hip, or rake of a roof includes a forward exposure area and a rear headlap area. The multi-layer cap shingle includes at least two layers of shingle material, a top layer and a bottom layer each having opposed edges. The layers are bonded together with patches of lamination adhesive adjacent their opposed edges. The bottom layer is configured with a deformation-absorbing mechanism such as a pair of slots extending from a forward edge reawardly inboard of the lamination adhesive patches. When the multi-layer cap shingle is bent over a roof ridge, the slots of the bottom layer of shingle material narrow in width to account for the fact that the bottom layer must bend around an arc of slightly smaller radius than the top layer of shingle material. As a result, the opposed edges of the bottom and top layers of shingle material remain aligned and both edges of the top layer are laminated to the bottom layer to increase wind lift resistance of the installed multi-layer cap shingle.

A shingle includes a substrate having an asphalt coating on a top surface of the substrate and on a bottom surface of the substrate. A surface layer of granules is embedded in the asphalt on the top surface of the substrate. A backdust layer of particles is embedded in the asphalt on the bottom surface of the substrate. A sealant is disposed on the backdust. A hydrophobic material is applied to the sealant.

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 two 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.

The invention relates to a photovoltaic roof covering comprising a base tile having an anchor portion to anchor the base tile to part of a roof in use and wherein a spacer is provided to support a portion of another overlaid base tile in use by spacing the overlaid tile from the photovoltaic panel. Also included is a roof covering with a base tile having a first planar upper face and a second opposing lower face. The base tile comprises an anchor portion located towards one end of the second lower face of the base tile and is configured to anchor the base tile to part of a roof structure in use. A connecting portion is configured to connect the base tile to an adjacent base tile in use. The roof covering further comprises a rectilinear cover panel having upper and lower opposing faces and a width that is smaller relative to a width of the first planar upper face of the base tile. The base tile and the cover panel are arranged such that side edges of the cover panel are offset relative to side edges of the first upper planar face of the base tile. An inset is thereby created at one side edge and an overhang of the cover panel at the opposing side edge, wherein the base tile and the cover portion are coupled in this offset configuration.

A shingle including a substrate having a first surface defining an upper side of the shingle and an opposing second surface defining a lower side of the shingle; asphalt infiltrating the substrate to form a first asphalt coating on the first surface of the substrate and a second asphalt coating on the second surface of the substrate; a plurality of granules embedded in the first asphalt coating; a first hydrophobic material; and a second hydrophobic material that is a different composition than the first hydrophobic material and the second hydrophobic material comprises a metal stearate, wherein the lower side of the shingle includes a lower surface and the first and the second hydrophobic material are disposed on the lower surface.
