The present disclosure relates generally to roofing systems, for example, suitable for covering the roof of a house or other building. The present disclosure relates more particularly to a roofing system that includes a plurality of riser blocks disposed on a support surface. The riser blocks include a group that is aligned in a row. A batten extends along the row and is supported by the group of riser blocks. The batten includes a first clip portion. A group of roofing panels is disposed along the row and is supported by the batten. Further, each of the roofing panels of the group includes a front surface, a rear surface, and a second clip portion extending from the rear surface. The second clip portion is configured to engage the first clip portion of the batten so as to secure the roofing panels to the batten.

A lighter, more cost-effective roofing system and method, which includes a rain diverting feature for directing rainwater and snowmelt away from an underlying sheet material and roof deck, is provided. The invention includes a sheet material having an upper surface and a lower surface. The upper surface includes one of a hook and loop fastener and the lower surface is configured to be attached to the roof deck. The present invention further includes a plurality of roofing tiles, each tile having hook and loop fasteners adhered to a back face which extend along the width of the tile at or near the uppermost and lowermost edges. Each rain diverting feature, which is a strip-like device with one surface made up of a plurality of hook portions and an opposing surface made up of a plurality of portions complementary to the hook portions, is positioned between and releasably attached to the hook and loop fasteners located on a side-edge portion of two adjacent tiles and the underlying sheet material, thereby releasably attaching the tiles to each other and to the upper surface of the underlying sheet material. The use of rain diverting devices to direct rainwater and snowmelt away from the underlying sheet material and roof deck allows for single lap tiling and thus less weight on the roof deck. It also allows for shorter tiles to be used, thus saving material cost.

Present disclosure relates to an assembly for mounting solar panel tiles or other tiles/panels over a roof (surface). Assembly includes C-shaped base frames provided with holes at the bottom for fixing them parallelly over the roof. Rows of tiles are then mounted over two adjacent base frames. Assembly further includes Z-shaped clamping frames for holding the tile which sits and is mounted on the base frames. Clamping frames hold the tile at the top, and the bottom of another tile resting on a previous clamping frame. An area close to the bottom edge of tiles has a layer of adhesive that helps in attaching the bottom edge of tile to the top of a previous clamping frame, thereby making the assembly aesthetically pleasing and leakproof. Another set of holes are provided on the base frames, and clamping frames, to allow cables to pass through them, and provide proper ventilation beneath the assembly.

A system and method for expedited tile installation are disclosed. The system may include a clamp strip and at least one tile. The clamp strip may be made of conjoined foldable strips. Each strip may include one or more clamps. The clamp strip role may be configured to unroll on a surface. The clamp strip may be adhered to the surface, after unrolling, using one or more fastening mechanisms. The at least one tile may include one or more wedges fixed to a rear side of the at least one tile. Each wedge may be configured to be inserted into the one or more clamp for installing the at least one tile. The one or more clamps and the one or more wedges may be configured to interlock for gripping the at least one tile to the clamp strip.

A tile system comprises at least two tiles and at least one elongate support. Each tile is generally rectangular in shape and has a first edge, and a second edge, the second edge being generally opposite the first edge. Each elongate support has an attachment portion and a support portion. Proximate the first edge each tile is provided with a groove, the groove being configured to receive the support portion of one of the elongate supports and a portion of an adjacent tile proximate its second edge.

A roof integrated photovoltaic (RIPV) system has a plurality of solar tiles that are mounted to a roof. The tiles may be mounted using a metal batten and hanger system or some other attachment system. Each tile has an electrical edge junction extending rearwardly from its top edge. The edge junction is coextensive with or contains the plane of the solar tile and may be slightly thicker than the solar tile. Sockets on opposed ends of the edge junction receive plugs of electrical cables for interconnecting the array of solar tiles together electrically. The edge junctions provide for a low profile installation that mimics the appearance of a traditional roofing tile such as a slate tile. The slightly thicker edge junctions may raise solar tiles of one course above the surfaces of solar tiles of a next lower course to provide ventilation for the RIPV array and to provide accommodating space for system wiring.

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.

An improved roofing system including a batten assembly comprising support battens and clips. The clips are made of metal wire having one portion shaped to retain roof outer coverings and a further portion shaped to secure the clip to the batten by spring torsion force of part of the clip acting against the batten.

A method and apparatus for installing roofing shingles on a roof deck in a top-to-bottom manner is disclosed. Engineered battens am positioned and installed on the roof deck in a bottom-to-top manner. Each batten has a female mating area which allows complementary shingles to be securely attached to the battens by sliding a corresponding mating portion of a shingle into the mating area of the batten resulting in a snap-fit engagement which secures the shingles onto the roof deck without nails. The method and apparatus have several unique advantages, such as allowing shingles to expand and contract (“breathe”) without buckling and/or tearing when the ambient temperature fluctuates. In addition, since the manner of installation is from top-to-bottom, this allows roofers to use the rows of nailed battens as safety scaffolding improving roofers' traction and ultimately enhancing their safety while performing this inherently dangerous job.
