A method of making a laminated shingle is provided. The method includes coating a shingle mat with roofing asphalt to make an asphalt-coated sheet, adhering a reinforcement member to a portion of the asphalt-coated sheet, covering the asphalt-coated sheet, and optionally covering the reinforcement member, with granules to make a granule-covered sheet, dividing the granule-covered sheet into an overlay sheet and an underlay sheet, wherein the overlay sheet has a tab portion normally exposed on a roof and a headlap portion normally covered-up on a roof, the headlap portion having a lower zone adjacent the tab portion and an upper zone adjacent the lower zone, and wherein the reinforcement member is adhered to the lower zone of the headlap portion and laminating the overlay sheet and the underlay sheet to make the laminated shingle.

A novel roof shingle tile and method of installation is presented. The roof shingle may include a first side opposite a second side, a top edge opposite a bottom groove, a top gutter, and a side gutter. The bottom groove may extend along a bottom edge of the tile that includes a bottom edge of the side gutter, and the top edge may include a tongue portion sized to fit within the bottom groove of a vertically adjacent tile. The second side may also include an overhang portion sized to overlap the side gutter of a horizontally adjacent tile. When installed, the shingle tiles may create a water resistant roof surface.

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.

Some embodiments of the present disclosure relate to a roofing system. In some embodiments, the roofing system includes a first roofing material, wherein the first roofing material comprises a top surface and a bottom surface. In some embodiments, the top surface of the first roofing material comprises a nail zone with a plurality of fines. In some embodiments, the roofing system includes a second roofing material, wherein the second roofing material comprises a top surface and a bottom surface. In some embodiments, the bottom surface of the second roofing material comprises a plurality of fines. In some embodiments, the roofing system comprises and a patterned adhesive, which directly contacts at least a portion of the plurality of fines in the nail zone and at least a portion of the plurality of fines on the bottom surface of the second roofing material.

A roof tile comprising a decorative layer, the decorative layer comprising a ceramic body, and a support layer disposed below the decorative layer, wherein the roof tile comprises an upper edge, a lower edge which is opposite to the upper edge and two opposite side edges, the opposite side edges being transverse to the upper edge, wherein the roof tile comprises at least a first coupling elements configured for being coupled to an adjacent roof tile in a roof covering, and wherein the first coupling elements are provided at least at one side edge of the roof tile.

A roof tile comprising a decorative layer, having at least a ceramic body, and a support layer disposed below the decorative layer, wherein the roof tile comprises an upper edge, a lower edge which is opposite to the upper edge and two opposite side edges, said side edges being transversal to the upper edge, wherein said roof tile comprises at least one anchoring element for anchoring the roof tile to a structure or framework.

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.

A fastener-protecting roofing shingle provides a solution for roofing nails or fasteners that become damaged due to weather exposure resulting from damaged roofing shingles. A nailing line is placed above a seamline rather than on or below the seamline, as is conventionally found. By placing the nailing line further from the seamline, which typically borders the exposed and the overlapped sections of a shingle, nails are better-protected from being exposed to the elements, which decreases the chances of failure due to the nail rusting. Due to the shift in the nailing line, a spotted adhesive may be positioned approximately two inches below the nailing line for improved rooftop adherence, and the length of a solid section may be increased. Furthermore, the apparatus directs rainwater straight down the roof. Solid adhesive strips prevent water from pooling or leaking laterally out to the sides and into other layers of shingling.

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.

A porcelain roof tile installing system that comprises a roof tile having a porcelain body provided with an attachment hole; a nail for being inserted into the attachment hole of the roof tile thereby installing the roof tile to a roof structure; a nail gun for pushing the nail into the attachment hole; wherein the nail gun has a centering element configured to be coupled with the attachment hole.
