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 roofing material comprising a substrate constructed at least in part of a carbon fiber material and a weather-resistant or water-proof coating affixed or applied to the substrate. Aesthetic or reflective materials may be applied to the exposed portion of said roofing material. The substrate may include woven and/or nonwoven fibers. The substrate may comprise a single layer or two or more layers of carbon-fiber material laminated by one or more binding layer. In addition, the present roofing material may include a bonding agent or primer for promoting adhesion between one or more carbon fiber substrate layers and/or a carbon fiber substrate layer and the weather-resistant or water-proof coating.

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 roofing system for protecting a building comprises a plurality of side-interlocking and front-to-back interlocking roof panels. A top side includes a front flange projecting forward at a front end. One or more gutter panels may be included, each having a top side open to a U-shaped gutter. An interior of each roof panel and gutter panel includes an insulating foam material, and an outer surface includes a rigid shell. The gutter panel is adapted for fixing along an edge of the roof at least partially under the flange of any of the roof panels that are disposed along an edge of the roof. Preferably the roofing system further includes gable cap panels, soffit fascia panels, valley cap panels, and wind breakers for holding the roof panels down to the roof in wind.

Bituminous tile with sealing engagement devices delimiting positioning areas of the anchoring nails including a tile body of the layered type and provided with shaped flaps delimited by separation cuts, wherein the upper face of the tile body is provided with a plurality of sealing engagement devices which are made in such a way as to have an immediately identifiable nailing area which is perimetrically delimited by a sealing engagement area that is made of an adhesive and/or thermally adhesive and/or hot melt material. The sealing engagement area enables the bonding engagement of the corresponding flap of the bituminous tile that in a laid condition is thereby overlapped, also enables a perfect sealing of the insertion area of the anchoring nail.

The present invention relates generally to the photovoltaic generation of electrical energy. The present invention relates more particularly to photovoltaic arrays for use in photovoltaically generating electrical energy. Aspects of the present invention provide a variety of photovoltaic roofing elements and systems that include, for example, interlocking geometries to provide for water handling and integration with conventional roofing materials; and wire management features that can protect wiring and associated electrical components from physical and/or environmental damage.
