Disclosed is an additive manufacturing process for making shingles and roof tiles. The entire shingle, including the substrate, can be manufactured on location, or a substrate can be manufactured at a manufacturing plant and then colored and textured on location to provide a wide variety of shapes and colors of shingles and roof tiles. Costs for inventory and shipping are reduced and a greater variety of shapes and colors can be provided for the shingles and roof tiles. The additive manufacturing equipment can be mounted on a truck so that the additive manufacturing techniques can be a mobile application of the additive manufacturing technology.

A solar energy roof tile, thermally and/or electrically conductively connected to an adjacent solar energy roof tile, includes a lower face for placing on at least some regions of a roof construction, an upper face opposite the lower face formed at least in some regions by a solar energy utilisation module, two opposite lateral walls, a rear face connecting the lateral walls, and a front face opposite the rear face that connects the lateral walls. The two lateral walls, the rear face and front face together connect the lower and upper faces, such that a cavity is formed between the two lateral walls, the rear face, front face, and lower and upper faces. The lower face has, in the region of the front face, a lower opening for providing access. The upper face has, in the region of the rear face, an upper opening for providing access into the cavity.

Some embodiments of the present disclosure relate to roofing systems. In some embodiments, the roofing system includes a deck, a roofing material, and an underlayment configured to be positioned between the roofing material and the deck. In some embodiments, the underlayment comprises a foil layer and an adhesive layer that is attached to the foil layer and attachable to the deck. Methods of manufacturing roofing systems are also disclosed.

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.
