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 cellular glass insulation system for an outer surface of a structure or pipe. The insulation system includes multiple segments of cellular glass. An adhesive having a reduced permeability is provided at the interface between the individual cellular glass segments and is configured to limit water intrusion that might cause corrosion of the structure or pipe.

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 roofing system including a cap shingle and a method of producing a cap shingle are disclosed. In one embodiment, the cap shingle is formed with a continuous or discontinuous self-sealing adhesive that is applied along a ridgeline direction and can provide high wind resistance, without the use of hand-sealed adhesive application. In an embodiment of the method, one or more layers of a shingle material can be oriented in a machine direction with the self-sealing adhesive applied adjacent side edges of the shingle material to form the cap shingles having self-seal strips and configured to bend in the machine direction for installation of the cap shingles along a ridge of a roof.

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.

A laminated composition shingle includes a first sheet having a first mineral granule surface and a first rectangular shape without tab cut-outs laminated with a second sheet having a second mineral granule surface. The second sheet has tab cut-outs along only one longer edge of the second sheet. The laminated composition shingle has a shingle width and an exposure width perpendicular to the long edges and a first width that is twice the exposure width. The shingle width is the first width plus 2 inches (51 mm). The tab cut-outs have a tab width in the direction of the shingle width less than the exposure width minus ⅛ of an inch (3 mm).

A plurality of granules comprising particulate silicate material bonded together with an inorganic binder, the inorganic binder comprising reaction product of at least alkali silicate and hardener, wherein the hardener is at least one of aluminum phosphate, amorphous aluminosilicate, fluorosilicate, Portland cement, or a calcium silicate, wherein the particulate silicate material is present as at least 50 percent by weight of each granule, based on the total weight of the respective granule, wherein each granule has a total porosity in a range from greater than 0 to 50 percent by volume, based on the total volume of the respective granule, and wherein the granules have Tumble Toughness Value of at least 70 before immersion in water and at least 40 after immersion in water at 20° C.±2° C. for two months. The granules are useful, for example, as roofing granules.

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.

A roof tile comprising a ceramic body and a reinforcing element attached to a lower surface of the ceramic body.

A shingle including a substrate having a first surface defining an upper side of the shingle and an opposing second surface defining a lower side of the shingle; asphalt infiltrating the substrate to form a first asphalt coating on the first surface of the substrate and a second asphalt coating on the second surface of the substrate; a plurality of granules embedded in the first asphalt coating; a first hydrophobic material; and a second hydrophobic material that is a different composition than the first hydrophobic material and the second hydrophobic material comprises a metal stearate, wherein the lower side of the shingle includes a lower surface and the first and the second hydrophobic material are disposed on the lower surface.
