The present disclosure relates to a system for mounting solar panel tiles (or other tiles/panels) over a roof (surface). The system includes mounting frames provided with holes at the bottom for fixing them parallelly over the roof. Bolting members and overhang members are attached to two opposite sides of the tiles to form a tile assembly. The bolting members and overhang members of the tile assembly are provided with a set of holes to allow coupling of the tile assembly between two adjacent mounting frames using bolt/screws. Further, sealing agents are provided on the edges of the tiles as well as the tile assemblies, thereby making the system aesthetically pleasing and leakproof. Another set of vents are provided on the base frames, to allow cables to pass through them, and provide proper ventilation beneath the tiles.

A shingle assembly for installation on a roof structure is provided. The shingle assembly can include an insulative substrate, a surface sheet coupled to and extending across a substantial portion of the insulative substrate, and a hook-and-loop fastening system comprising a hook portion and a loop portion. The hook portion or the loop portion can be coupled to and extend along the insulative substrate adjacent the surface sheet. The other of the hook portion or the loop portion can be coupled to and extend along the surface sheet. The hook portion can be configured to mate with a loop portion of a first adjoining shingle assembly and the loop portion can be configured to mate with a hook portion of a second adjoining shingle assembly.

A metallic roof material 1 according to the present invention comprises: a front substrate 10 made of a metal sheet, the front substrate 10 comprising a body portion 100 formed into a box shape; a back substrate 11 arranged on a back side of the front substrate 10 so as to cover an opening of the body portion 100; and a core material 12 filled between the body portion 100 and the back substrate 11, the metallic roof material 1 being tightened to a roof base by driving at least one tightening member into the body portion 100, wherein a top plate portion 101 of the body portion 100 comprises at least one protruding rib 3 comprised of at least one protrusion 30 disposed along a side of a polygon or along a circle, and wherein the metallic roof material 1 is configured such that the tightening member is driven into an inner region 3a of the protruding rib 3.

An integral nail/disk structure that eliminates the need of having any exposed nails associated with a shingled roof having a color matching body member integrally formed with a roofing nail. Another embodiment including a fastener such as a nail or screw having an enlarged head and an associated gasket member for fastening sheet metal to a roof structure. The gasket member has a sealant on both of its top and bottom surfaces so as to adhere both to the underside of the enlarged head portion of the nail or screw, and to the sheet metal to create a waterproof seal. Still another embodiment includes an enlarged cap member associated with a gasket member attached to its underside portion wherein the cap/gasket member can be attached over a fastener hole in a roof, or over a faulty roofing nail or screw in lieu of caulking techniques usually used to cure leaks where the faulty fastener attaches sheet metal to a roofing structure.

The present disclosure provides a new design for an injection molded roof panel with multiple improvements. The panel is made from PVC-like materials via injection molding with a large standard size. It comprises laterally and longitudinally sloped watercourses and arches. A tongue at the front connects to a vertically adjacent panel's rear upper interlocking member. Interlocks at the lateral ends of the panel connect one panel to another horizontally adjacent panel. Condensed water ridges underneath the panel drain condensation to the panel's front, where it is drained with angled weep holes on the tongue. The upper surface has a non-smooth low-noise texture to prevent slips/falls and reduce noise. The roof panel is secured onto roof sheathing with nail flanges with screw holes/bosses. The design achieves improved water drainage, increased installation security and speed, improved wind resistance, increased personnel safety, reduced noise, lighter weight, lower cost, and improved lifespan.

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.

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 solar cell module includes a solar cell section and a step forming plate. The solar cell section includes a front side transparent plate, a back surface member, and a solar cell sealed therebetween. The step forming plate is disposed on a front side of the front side transparent plate, overlapping partly with the front side transparent plate and forming a step between the solar cell section and the step forming plate.
