Abstract:
The present invention relates generally to roofing products. The present invention relates more particularly to roofing products for use with photovoltaic elements, and to photovoltaic systems that include one or more photovoltaic elements is joined to a roofing substrate. In one embodiment, a roofing product includes a flexible roofing substrate having a top surface, the top surface having one or more receptor zones thereon, each receptor zone being adapted to receive one or more photovoltaic elements, each receptor zone having a different surfacing than the area of the top surface adjacent to it.
Abstract:
A multilayer roofing sheet includes a laminate formed from an upper sheet having a textured lower surface and a lower sheet having a fusible upper surface mechanically interlocked together.
Abstract:
A laminated roofing product can include a first sheet including a first coating that is substantially free of recycled roofing material, and a second sheet adjacent to the first sheet. The second sheet can include a second coating having a second sheet recycled roofing material. In another embodiment, the laminated roofing product can include a first sheet including a first sheet recycled roofing material, and a second sheet adjacent to the first sheet. The second sheet can include a second sheet recycled roofing material, wherein the second sheet has a higher recycled roofing content as compared to the first sheet. In another embodiment, a method of forming a laminated roofing product includes laminating a first sheet and a second sheet together. The second sheet has a higher recycled roofing content as compared to the first sheet.
Abstract:
A roof covering material is provided, as well as its method of manufacture, wherein a substrate, preferably of a fibrous material is provided, with a bituminous material, preferably asphalt coating, on opposite surfaces thereof, with granules being applied to an upper surface thereof and at least partially embedded in the bituminous material, and with a discontinuous top layer applied to the granule/bituminous material. The discontinuous top layer is preferably a polymeric material, and openings are provided therein, for passage of fluids therethrough, to avoid moisture, volatiles, and other fluid materials from being trapped beneath the top layer. Various techniques for application of the various materials, and for chemical treatment, are likewise provided.
Abstract:
A roll roofing material is provided in the form of a cylindrical roll that may or may not have an exterior covering thereon, and with transverse members being provided, carried by the cylindrical roll, and which protrude generally outwardly of an exterior cylindrical surface of the roll. The transverse members inhibit rolling of the roll roofing either off a pitched roof. One or more inserts may be provided in a hollow core of the roll, and connectors may attach a strap to these inserts for transporting the same from ground to a rooftop, or otherwise. Protective covers may be provided at opposite ends of the roll roofing, and the protective covers may comprise the transverse members, as may be desired.
Abstract:
The present invention relates more particularly to roofing products for use with photovoltaic elements, and to photovoltaic systems that include one or more photovoltaic elements joined to a roofing substrate. In one aspect, the invention provides a roofing product including: a bituminous roofing substrate having a top surface; and roofing granules embedded in the top surface of the roofing substrate, wherein in at least one over-pressed zone of the roofing product, the roofing granules are embedded so that (a) the over-pressed zone exhibits a 0.20 gram loss or less in a rub test as described in ASTM D-4977; or (b) in the over-pressed zone the average granule embed volume fraction is at least 0.5; or (c) in the over-pressed zone, the average distance between the top of the roofing granules and the top surface of the bituminous roofing substrate is 1.0 mm or less.
Abstract:
A photovoltaic module includes an encapsulated photovoltaic element and an infrared-transmissive decorative overlay simulating conventional roofing.
Abstract:
A plurality of hip, ridge or rake shingles, and the shingles produced thereby and stacks and packages of such shingles are provided.An adhesive impregnated mat is moved longitudinally, and granules are provided onto adhesive, in predetermined bands. An overlay band of adhesive, continuous or discontinuous is provided, with granules thereon, increasing the thickness of the shingle material being made, in predetermined bands, relative to the remainder of the shingle material. The shingle material is slit longitudinally, and one portion can be laminated to another portion, preferably creating a multiple-ply laminated shingle material with thickened overlay portions and optionally with shadow line portions. The material is then slit longitudinally, and cut transversely into a plurality of hip, ridge or rake shingles, which may be individually separated from each other, or which may comprise a plurality of connected together shingles. The shingles are then stacked and wrapped.

Abstract:
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.
