A fastener plate for use in coupling an underlayment to a roof surface is disclosed. In use, the fastener plate is arranged and configured to enable subsequently applied liquid coatings to flow through a top surface of the fastener plate and into one or more cavities so that the liquid coating seals any openings created by introduction of the fastener. In one embodiment, the fastener plate may include a top surface, a bottom surface, a fastener opening for receiving a fastener, a plurality of openings formed in the top surface, and one or more cavities positioned between the top surface and the bottom surface, the one or more cavities being in fluid communication with the plurality of openings so that the liquid coating can flow through the plurality of openings formed in the top surface and into the one or more cavities to seal any voids created by the fastener.

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.

A metal shingle having a body with left, right, top and bottom parts. The body is substantially planar and rectangular and has a front, a rear, left and right sides, a top and a bottom. The left and right parts extend from the left and right side respectively. One of the left and right parts is folded over the front and the other is folded over the bottom. The top and bottom parts extend from the top and bottom respectively. One of the top and bottom parts is folded over the front and the other is folded over the bottom. In use, the shingles are positioned in each of side-to-side and top-to-bottom abutting relation so that adjacent sides are interlocked. The body defining a hollow adjacent to one of the interlocking top and bottom parts.

Roofing systems are disclosed herein. In particular, a method of making an asphaltic roofing product having an asphaltic substrate and at least one granule disposed thereon is disclosed herein.

A system includes a plurality of photovoltaic modules, each having a mat with an edge and a spacer with an edge, the edge of the mat being attached to the edge of the spacer. The spacer includes a plurality of support members and a solar module mounted to the support members. Each of the support members includes a ledge. The solar module and the ledge form a space therebetween. The space is sized and shaped to receive an edge of a solar module of another of the photovoltaic modules. The spacer of one of the photovoltaic modules overlays the mat of another of the photovoltaic modules.

Roofing granules comprising agglomerated inorganic material, and building materials, such as shingles, that include such roofing granules. By fabricating roofing granules from agglomerating inorganic material it is possible to tailor the particle size distribution so as to provide optimal shingle surface coverage, thus reducing shingle weight and usage of raw materials. Additionally, the use of agglomeration permits the utilization of by-products from conventional granule production processes.

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.

Embodiments relate to an enhanced method for installing solar roofs by primarily reducing the installation time. The design is for a roofing shingle with an embedded solar module that installs intuitively like normal roofing shingles without special tools, fasteners or alignment. The shingle structure is molded out of low thermal expansion plastic composite and is compatible with commercial photovoltaic modules as well as solar infrared radiation absorbing devices.
