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 photovoltaic module having photovoltaic cells, each having a width, and a roofing shingle having an exposure zone and a headlap zone. A plurality of slots extends from the exposure zone to the headlap zone and define tooth portions. A first one of the tooth portions has a first side defined by a first slot and a second side defined by a second slot adjacent to the first slot. The first tooth portion has a first width that is the photovoltaic cell width multiplied by a first positive integer. A second tooth portion has a first side defined by a third slot and a second side defined by a fourth slot adjacent to the third slot. The second tooth portion has a second width that is the photovoltaic cell width multiplied by a second positive integer different than the first positive integer.

A roofing shingle has an upper surface, a lower surface, and a sealant material applied along the lower surface. A pressure relief channel is formed along the lower surface of the roofing shingle, with a release strip applied over the pressure relief channel. When the roofing shingle is paired with another roofing shingle in a stack, the sealant material of the roofing shingle is arranged in registration with the release strip and pressure relief channel of the other roofing shingle.

The present disclosure relates particularly to a laminated roofing shingle that comprises a nailing zone in which the roofing granules in that nailing zone have been overpressed into the underlying bituminous substrate creating a visually distinct overpressed nailing zone.

This invention relates to a roofing, cladding, or siding module, comprising an underlapping region extending from a head edge of the module and an exposed region extending from a foot edge of the module. The length of the foot edge defining the length of the module. The underlapping region is adapted to be substantially covered by the exposed region of an adjacent or overlapping module when installed on a building surface. The module is formed of at least one layer of extruded material. The layer so formed comprises at least 40% w/w filler and/or reinforcement, and one or more polymer(s).
