A solar power system for a metal shingled roof, including: a plurality of metal roofing shingles; and a plurality of solar module mounting assemblies, wherein each of the solar module mounting assemblies has upper and lower module cleats that support upper and lower solar module frames thereon such that the upper and lower module frames are both spaced apart in a direction parallel to the roof, and spaced apart in a direction perpendicular to the roof.

Shingles have self-seal strips with features that include sealant dashes or dots separated by drainage gaps. The self-seal strips are registered with each shingle so that the features are positioned at the same locations on each shingle. A method of making such shingles includes synchronizing the rotation of sealant applicator wheels with the shingle chop cutter so that cuts are made at repeated designated locations along the applied self-seal strips.

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 roofing shingle includes a head lap and at least one solar cell. The head lap includes at least one handle located between a first end and a second end of the shingle and proximate to a first edge thereof. The at least one handle includes at least one cutout and a gripping portion. The at least one cutout is sized and shaped to receive an external object to facilitate transporting the shingle by a user.

Shingle blanks including a first fold region, a second fold region, a third region, a lower edge and an upper edge are provided. The shingle blank has a length. The first and second fold regions extend substantially across the length of the shingle blank. The second fold region is positioned between the first and third fold regions. A first perforation line is positioned between the second and third fold regions. A second perforation line is positioned between the first and second fold regions. A reinforcement material is positioned over the first perforation line and configured to reinforce the first perforation line. The reinforcement material includes apertures configured to allow an asphalt coating to bleed through the reinforcement material. The first and second perforation lines facilitate folding of the first and second fold regions on top of the third region to form a three layered stack.

A shingle comprises an overlay, an underlay, and a height increasing material disposed between the overlay and the underlay. The height increasing material includes a first adhesive adhered to the overlay, height increasing granules adhered to the first adhesive, and a second adhesive adhered to the height increasing granules and the underlay. The height increasing material can extend along front ends of tab portions of the overlay, along front cutout edges that extend between tab portions of the overlay, or both.

The present invention relates generally to the photovoltaic generation of electrical energy. The present invention relates more particularly to photovoltaic arrays for use in photovoltaically generating electrical energy. Aspects of the present invention provide a variety of photovoltaic roofing elements and systems that include, for example, interlocking geometries to provide for water handling and integration with conventional roofing materials; and wire management features that can protect wiring and associated electrical components from physical and/or environmental damage.

Roofing panels for concealing a biocidal source are described. In embodiments, the roofing panels include a body having as top side, a bottom side parallel with the top side, a front edge, a rear edge, and a left edge. The roofing panels may further include a first sidewall, a second sidewall, and one or more standoffs. The first and second sidewalls may have a tapered sidewall height that provides a gap between the body of the roofing panel and underlying material. The roofing panel may be installed over a biocidal source on a roof, concealing the biocidal source from view while still allowing liquid (e.g., water) to flow over the biocidal source.

This invention, in embodiments, relates to a roofing system comprising (a) a roofing substrate having a roofing surface, (b) a first roofing tile overlying the roofing surface, the first roofing tile having a front surface, a back surface, a top edge, and a bottom edge, and (c) a second roofing tile overlying the first roofing tile, the second roofing tile having a front surface, a back surface, a top edge, and a bottom edge. At least one sealant line is applied to (i) the back surface of the second roofing tile in an area that overlays the first roofing tile, (ii) the front surface of the first roofing tile in an area in which the second roofing tile overlays the first roofing tile, or (iii) both (i) and (ii). The at least one sealant line is configured to adhere the second roofing tile to the first roofing tile.
