A roofing system has metal shingles that have formed side lap features that are configured to facilitate alignment of adjacent side lapped metal shingles of a shingle installation along a roofing structure and that couple the metal shingles together and form seals along their side lapped peripheral edges. The metal shingles also can have alignment features that cooperate to align shingles in one course with shingles in a next lower course within their headlap regions.

The roofing system also has standing seam features configured to couple to the metal roofing shingles to cover the formed seams.

A multi-layered integrated roofing plank or panel with a base layer comprising engineered or manufactured wood, a water resistant barrier layer covering at least the outer face of the base layer, and at least one of the edges of the base layer. A texturizing material also may be affixed to, or integrated with, the water resistant barrier layer. The edges of the roofing plank or panel may be configured as part of a joint with adjacent planks or panels, including, but not limited to, shiplap joints, tongue-and-groove joints, bead-and-cove joints, butt joints, or combinations or variations thereof.

Roofing panels for concealing a biocidal source are described. In embodiments, the roofing panels include a body having as top side, a bottom side parallel with the top side, a front edge, a rear edge, and a left edge. The roofing panels may further include a first sidewall, a second sidewall, and one or more standoffs. The first and second sidewalls may have a tapered sidewall height that provides a gap between the body of the roofing panel and underlying material. The roofing panel may be installed over a biocidal source on a roof, concealing the biocidal source from view while still allowing liquid (e.g., water) to flow over the biocidal source.

A roofing system for forming a roof includes a plurality of tiles. Each tile has a frame at a perimeter of the tile, and the frame includes an upstream element, an opposed downstream element, and opposed first and second side elements, thereby bounding a central panel area. Each tile further includes a side trim, a batten, and a ridge cap. When the tiles, side trim, batten, and ridge cap are arranged to form a roof, the batten is secured at a lower edge of the roof and directed upward to receive the downstream elements of the tiles, the side trim is secured at a side edge of the roof and directed laterally to receive one of the first and second side elements of the tiles, and the ridge cap is secured at a ridge of the roof and directed downward to lap over the upstream elements of the tiles.

A roofing, cladding or siding module is described. The module comprises an underlapping region adapted to be substantially covered by an exposed region of an adjacent overlapping module when installed on a building surface. A plurality of projections are formed on an underside of the underlapping region. The projections are feet to support the module on the building surface to provide a gap between the module and the building surface, and/or provide a profile on the underside of the underlapping region to define a pathway for air flow between the module and the building surface. Each projection is formed by a downwardly projecting portion of the underlapping region with a corresponding cavity in an upper side of the underlapping region, and the cavity is shaped to prevent or minimize water pooling in the cavity.

There is provided a cladding member (13) formed of a supporting body portion (67) having mounts (54) and a head portion (12), and an absorber surface portion (70) having a peripheral boundary wall (71) defining a recess into which a solar cell array (removed in this view for clarity) is bonded. The supporting (67) and absorber surface (70) body portions are pressure moulded from polyvinyl ester/glassfibre (30%)/fire retardant (40%)/pigment sheet moulding compound. Complementary bonding portions (72) form a glue line in assembly and have complementary water passages (73) defined therebetween. The bonding portions (72) contrive a generally sinusoidal glue space (74) that is longer that the transverse sectional dimension of the boding portions (72), cooperating with the adhesive system to resist water pressure in the passages (73).

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.
