Herein disclosed is an asphalt roofing shingle, adapted to be laid up in courses on a roof, comprising an upper headlap portion, a lower tab portion, vertically spaced apart upper and lower edges, laterally spaced apart right and left edges and top and bottom surfaces. The bottom surface is configured to be laid up on a roof facing the roof and the tab portion of the top surface is configured to be substantially weather-exposed when laid up on a roof. The upper headlap portion is configured to be substantially covered by the tab portion of roofing elements in a next-overlying course of roofing elements when laid up on a roof. The upper headlap portion further comprises a plurality of parallel, evenly laterally spaced, first markings, the first markings being useful, at least, for aligning adjacent shingles, cutting books of shingles, forming starter shingles from full shingles and forming a grid of shingles without external measuring devices.

One aspect of the disclosure is an exterior cladding panel including a first end, a second end, and a series of locking clips extending from a front face of the exterior cladding panel and positioned along the first end of the exterior cladding panel. The exterior cladding panel also includes a locking leg extending from a rear face of the exterior cladding panel and positioned along a middle portion between the first end and the second end. The exterior cladding panel also includes a series of simulated shingles positioned in a single course between the first end and the second end, including a series of gaps separating adjacent shingles. Each gap extends lengthwise from the second end to the middle portion of the exterior cladding panel, and includes a first width that differs from a second width of at least one adjacent gap in the series of gaps.

One aspect of the disclosure is roofing shingle including a first shingle layer having a top surface, a first side edge, and a second side edge positioned opposite the first side edge. The roofing shingle also includes a second shingle layer at least partially laminated to the top surface of the first shingle layer, where the second shingle layer includes a first side edge offset a sidelap distance from the first side edge of the first shingle layer such that a side portion of the top surface of the first shingle layer is exposed, and a second side edge extending beyond the second side edge of the first shingle layer so as to overlap the second side edge of the first shingle layer by the sidelap distance.

Building integrated photovoltaic (BIPV) systems provide for solar panel arrays that can be aesthetically pleasing to an observer. BIPV systems can be incorporated as part of roof surfaces as built into the structure of the roof, particularly as photovoltaic modules having the appearance of a plurality of roofing tiles that each have photovoltaic cells. Each photovoltaic module may include a metal backer, photovoltaic cells, and light transmissive top sheets adhered to both the metal backer and the photovoltaic cells. BIPV systems can also include non-photovoltaic modules that appear similar to photovoltaic modules, but do not collect solar energy.

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.

In one aspect of a bottom indexing tile and support structure, a bottom indexing support structure may be engaged with a top portion of a pedestal. The bottom indexing support structure may be formed with a generally vertical spine having at least one rail extending outward from a distal end thereof and may also include one or more ridges extending upward in a direction parallel to the spine. The spine and rail(s) may be configured to secure one or more bottom indexing tiles, which tiles may be formed with a groove on at least one edge thereof, and wherein one or more rails may be positioned within the groove. The bottom indexing tile may be formed with one or more channels on a bottom surface thereof, wherein each channel may correspond with a ridge of the bottom indexing support structure.

A lightweight interlocking metal roof system for installation onto a steep or inclined structure roof either directly over the roof decking material or over an existing shingle roofing system, with the metal roofing system installed from the roof ridgeline down to the drip edge of the roof gutter. Cooperating outwardly extending flanges and receiving pockets for capturing and interlocking the metal panels of the roofing system create an interlock between and among panel members with overlying edge ends configured to be resistant to lift up due to winds either across the roof or along the roof edges.

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 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.

A roof tile system and a method for installing the roof tile system is disclosed. The roof tile system comprises a first roof tile and a tile-holding device. The first roof tile comprises a first attaching means, the first attaching means for attaching the first roof tile to a second roof tile when the first roof tile and the second roof tile are arranged together on a roof. The first roof tile further comprises a flange extending from a first end portion. The tile holding device for fixing tiles to the roof comprises a channel for receiving the flange so as to inhibit lifting of the first end portion away from the roof.
