A roof tile having a mesh covered foam core with a cement-based protective coating, a roof covering formed from such tiles and methods for making same.

The present application provides a photovoltaic profile, a photovoltaic roof tile module and a photovoltaic roof installation system. The photovoltaic profile comprises: a first frame, a second frame, a third frame and a fourth frame, the splicing corners of the frames are connected in sequence, and the splicing angle of the first splicing corner and the third splicing corner are both larger than the splicing angle of the second splicing corner and the fourth corners, and the first drainage channel and the second drainage channel are interconnecting to each other. The photovoltaic profiles, photovoltaic roof tile module and photovoltaic roof installation system of the present application can effectively drain rainwater through the interconnected drainage channels in the photovoltaic frame, avoiding rainwater damage to photovoltaic profiles and photovoltaic module, and improving the reliability of the overall waterproof performance of the roof. In addition, the photovoltaic frames are connected in sequence through splicing corners, and the splicing angles have a special angle design, so that the photovoltaic profile of the present application has the advantage of being simple in structure and easy to process.

In various embodiments, a tile system for mounting structures to a roof may comprise a base assembly, a fastener, a seal, a flashing, and a mounting bracket. The fastener may be installable on the base assembly. The seal may be installable on the fastener. The flashing may be configured to replace a roof tile. Moreover, a protrusion may be field formed in the flashing during installation of the tile system by driving the fastener through the flashing in response to the base assembly being positioned on the roof surface. The bracket may be installable on the fastener and configured to compress the flashing against the seal and the base assembly.

A device and method for covering a roof. The interlocking roof shingle includes a shingle having a top surface and a bottom surface. A first edge of the shingle is curved over the top surface and a second edge of the shingle is curved under the bottom edge of the shingle. The first edge of the shingle is configured to engage with the second edge of an adjacent shingle. The device further includes a tab configured to receive a nail and engage with the first edge of the shingle. Some embodiments of the shingle are configured to fit along the ridges and valleys of a roof. In these embodiments, the shingle has a center fold and a gap in the upper and lower folded edges.

A roofing system of the present disclosure has a first shingle layer and an overlaid layer a portion of which overlays the first shingle layer. Additionally, the roofing system has a first shingle in the first shingle layer, the first shingle having a first channel and a first protrusion in an upward-facing surface and the channel is contiguous with the protrusion, the channel and the protrusion formed on an interlocking end of the first shingle. Further, the roofing system has a second shingle in the overlaid layer, the second shingle having a second channel and a second protrusion in a downward-facing surface and the second channel is contiguous with the second protrusion such that the first channel is configured for receiving the second protrusion and the second channel is configured for receiving the first protrusion.

A roof tile having a mesh covered foam core with a cement-based protective coating, a roof covering formed from such tiles and methods for making same.

The present disclosure includes roof shingle systems. One roof shingle system includes at least two shingles, a shingle clip, a drip edge, and a power collection unit. Each shingle has a semiconductive layer configured to deliver power, electrical current/voltage, and/or control signals to the power collection unit. The shingle clip continues a conductive path between the two shingles. The drip edge is at least partially insulated and partially conductive, and the conductive portion continues the path from the shingle semiconductive layer to the power unit where energy is collected. One method of installing a shingle system includes the steps of positioning a shingle having a transducer in the form of a semiconductive layer, and positioning a shingle clip to engage the semiconductive layer of the shingle.
