A molded synthetic polymer based shingle is provided as is a roof made up of underlying and overlying of courses of such shingles. The shingles are generally rigid and are provided with upwardly protruding moisture guards on the upper surfaces of their headlap portions, for guarding against wind-blown moisture entering fastener locations at which fasteners are used to attach shingles to a roof. The moisture guards may be of various configurations and by either completely or incompletely surround the fastener locations. Shields having recesses for receiving moisture guards therein, or other downward projections, may be provided at under surface locations of the shingles in cooperative engagement for further protection against moisture penetration and for facilitating alignment of shingles relative to other shingles.

A shingle having butt and tab portions is provided, wherein the tab portions are exposed when applied to a roof, and wherein active photovoltaic element(s) appear on portions only of the tab portions of the shingles, wherein adjacent zones of the tab portions of the shingles to which the photovoltaic element(s) are applied are free of active photovoltaic elements. The shingles are applied to a roof or a major portion of a roof, laid up in courses so that exposed tab portions of next-overlying courses cover unexposed butt portions of next-underlying courses, leaving photovoltaic elements exposed. In an array of shingles on a roof, the photovoltaic elements are distributed substantially uniformally. The surface ornamentation of the exposed surfaces of the photovoltaic elements may be either complementary to the exposed surfaces of the shingles not having photovoltaic elements thereon, or may blend with such zones not having photovoltaic elements thereon.

A hip, ridge or rake shingle is provided, in which a pair of substantially rigid panel portions are connected by a hinge portion, and wherein the shingle is pre-assembled, but can conform to a variety of different angles to accommodate different angular relationships between surfaces of a hip, ridge or rake of a roof. The substantially rigid panel portions are connected by a hinge and may or may not have a reinforcement member, and all of the panels, hinges and reinforcement members are of synthetic thermoplastic polymeric construction and are welded together by ultrasonic or vibratory welding techniques.

A roof structure and a method of installing a snow guard on the base of a roof is provided, wherein the roof structure includes a plurality of synthetic shingles of thermoplastic materials, and where a snow guard is provided having an outwardly projecting snow-engaging platform and an oppositely provided hook at an upper end, wherein the hook is adapted to engage over and upper edge of a butt portion of one or more shingles in an underlying course of shingles, and wherein a tab portion of a shingle in a next-overlying course of shingles is disposed over the upper end of the snow guard, substantially covering its base, and wherein the snow-engaging platform is adapted to receive snow and ice that may slide down the roof, to intercept the same or break the snow or ice up into small harmless particles. The synthetic shingles of thermoplastic materials allow for the upward bending of the overlying tab portions of shingles a substantial amount within their elastic limit, to permit insertion of snow guards under tab portions of overlying shingles, where such tab portions of overlying shingles are already-installed on a roof, followed by a relaxation of the upwardly bent tab portions of shingles back to a flattened condition overlying the butt portions of shingles in an underlying course of shingles, and overlying the base of the snow guard between the platform and hook, due to the inherent memory of the original flattened shape of the shingles that have their tab portions flexibly upwardly bent.

One method for controlling edge thickness includes applying a coating to a moving substrate, thereby forming a film having a cross direction and a machine direction and one or more edges. The method also includes modifying a thickness of a first portion of the coating along one of the edges of the film, thereby forming a film having a substantially predetermined profile in the cross direction. A method of making a polymeric sheet includes applying a polymer to a moving substrate, thereby forming a sheet having a cross direction and a machine direction. This method further includes removing a first portion of the polymer from a first edge of the sheet, thereby the sheet having a substantially predetermined profile in the cross direction.

A photovoltaic module includes an encapsulated photovoltaic element and an infrared transmissive decorative overlay simulating conventional roofing.
摘要:
A process for making 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.
摘要:
Synthetic polymer based roofing elements of the shingle or tile type are provided whereby adjacent roofing elements have projecting tabs or nibs that are adapted to engage against side edges of adjacent shingles or tiles when laid up in courses on a roof, and wherein there are relatively flexible stress relief zones in the shingle or tile adjacent the tab or nib projections, adapted to be deformed within their elastic limit when the shingles or tiles are subjected to stresses due to thermal expansion and contraction, with the stress relief zones also being adapted to return to their original non-deformed condition when such thermal expansion and contraction forces are relieved.
摘要:
A roofing product having at least two separate zones, with one of the zones having one or more certain functional characteristics such as flame retardancy, solar reflectivity, weather resistance, selected coloring, heat stabilization, algae resistance, and/or solar collection for electrical generation, and another of the zones not having such functional feature(s). The different zones can be present in core or capstock material. The product can be made by any of various processes, such as co-extrusion, forming, molding, coinjection, shot injection moldings, multiple step injection moldings and/lamination.
