A roofing shingle including a lower layer including a headlap and a plurality of tabs extending from the headlap, and an upper layer including one or more fingers, wherein the one or more fingers are disconnected from one another, and wherein each of the one or more fingers is disposed on one tab of the plurality of tabs, wherein a number of the plurality of tabs is different than a number of the one or more fingers. In an embodiment, the lower layer is a lowermost layer of the roofing shingle. In another embodiment, the roofing shingle further includes an alignment feature disposed in an exposure zone of the roofing shingle, wherein the alignment features is adapted to permit alignment of adjacent roofing shingles during installation on a roof.

A solar shingle having a substrate positioned beneath an upper material layer and at least one photovoltaic cell coupled to the substrate. A first terminal can be electrically coupled to the at least one photovoltaic cell and positioned adjacent to a first sidewall of the solar shingle, and a second terminal can be electrically coupled to the at least one photovoltaic cell and positioned adjacent to a second sidewall of the solar shingle. An upper surface of the upper material layer can have one or more recesses positioned between the first sidewall and the second sidewall and adjacent to the at least one photovoltaic cell. Further, the upper surface can have a variety of imparted surface characteristics, among other aesthetics and coloring, that can provide the solar shingle with outwardly appearance that is at least similar to traditional, non-solar shingles.

A roofing system including a cap shingle and a method of producing a cap shingle are disclosed. In one embodiment, the cap shingle is formed with a continuous or discontinuous self-sealing adhesive that is applied along a ridgeline direction and can provide high wind resistance, without the use of hand-sealed adhesive application. In an embodiment of the method, one or more layers of a shingle material can be oriented in a machine direction with the self-sealing adhesive applied adjacent side edges of the shingle material to form the cap shingles having self-seal strips and configured to bend in the machine direction for installation of the cap shingles along a ridge of a roof.

Panels with substantially integrated watershedding features may be installed on the roof a house or other structure in lieu of traditional roofing materials. The panels include a body formed from a mixture of filler materials and polymeric binder materials, which can include recycled materials, with watershedding features generally formed with and/or integrated with the panels. The panels also can be installed in overlapping courses along a roof with the watershedding features incorporated along one or more peripheral edges. The watershedding features of adjacent panels further can cooperated to collect and divert water away from the upper surfaces and/or away headlap and/or sidelap joints defined between the panels.
