A roof system that includes a roof covering in the form of planting areas, a water storage, a wind turbine, a water turbine, a solar panel, and a water heater. The roof system includes a plurality of ceramic chambers each including a wind turbine and a recess for housing a planter area.

A high elongation ridge ventilation sheet for a sloping roof, having a coated composite aluminum membrane with multiple circular holes, each side of the coated composite aluminum membrane being bonded respectively with a folded composite aluminum membrane via a butyl adhesive tape for central linking, on a side of each folded composite aluminum membrane adjacent the coated composite aluminum membrane is arranged with a hot melt adhesive for connecting a polyester nonwoven fabric with each folded composite aluminum membrane, with the polyester nonwoven fabric covering the whole coated composite aluminum membrane. Further, a fabricating method therefor that realizes wholly dry construction; ridge ventilation sheets adopted on ridge locations not only make the whole roof prettier, but more importantly, enable air convection under the roof in a true sense, taking out extra dampness and heat, resulting in better energy saving effects, and extending life span for the roof.

A concealed roof vent has a base member having a primary aperture, a top panel coupled to the rear side of the base member and extending to the front side of the base member at an increasing angle, the top panel sized so as to shield the primary aperture; the top panel being coupled to the front side of the base member using one or more support legs; and at least one secondary aperture on the front side between the panel and the base member. Air from the attic passes through the primary aperture to the secondary aperture, through channels on the underside of roofing tiles, and to the atmosphere.

A roofing, cladding or siding product which is light weight, easy to install, durable, and resistant to environmental wear includes a module that can be used to form a weatherproof covering over top of a building surface. The module can also form a weatherproof covering, and be used as part of a thermal energy recovery or removal system. The module can also form part of a thermal energy recovery system that includes an array of solar cells to generate electrical energy.

One embodiment can provide a photovoltaic roof tile module. The photovoltaic roof tile module can include a photovoltaic roof tile module. The photovoltaic roof tile module can include at least: a first photovoltaic roof tile and a second photovoltaic roof tile positioned adjacent to each other, and a spacer coupled to and positioned between the first and second photovoltaic roof tiles. A respective photovoltaic roof tile can include front and back glass covers, and multiple cascaded strings encapsulated between the front and back glass covers. A respective cascaded string can include a plurality of photovoltaic structures electrically coupled to each other in series, and the multiple cascaded strings can be electrically coupled to each other in parallel. The first and second photovoltaic roof tiles can be electrically coupled to each other in parallel.
