Dimensional shingle for hip, ridge and rake portions of a roof
First Claim
1. A hip, ridge and rake shingle comprising:
- a. a top cover sheet, substantially rectangular in top plan, said top cover sheet being preformed into an inverted V-shape in cross-section and having a pair of side panels extending from a bendable median longitudinal peak to longitudinal bottom lateral edges, said side panels of said top cover sheet including a front end portion, a rear end portion, an upper surface and a lower surface; and
,b. a flexible and resilient substrate, substantially rectangular in bottom plan, said substrate being mounted on said lower surface of said top cover, said substrate having a leading end portion, located adjacent said front end portion of said side panels of said top cover sheet, a trailing end portion, located adjacent said rear end portion of said side panels of said top cover sheet, and a bottom surface, said substrate being preformed so as to have an inverted, V-shaped cross-section with a median longitudinal peak and bottom lateral edges and having a length and width less than the respective length and width of said top cover, so that said top cover sheet extends beyond the perimeter of said substrate to form an overhang around said perimeter, said leading end portion of said substrate being of substantially greater thickness than the thickness of said top cover, said substrate having a thickness tapering from said leading end portion of said substrate along the length thereof toward said trailing end portion, whereby said side panels of said cover sheet and said substrate are adapted to be bent around respective to conform to the configuration of an underlying hip, ridge, or rake.

Abstract
A shingle unit used for covering the hip, ridge and rake portions of an asphalt shingle roof. The shingle unit includes a top cover permanently bonded to a tapered substrate to create the visual effect of tapered thickness. The shingle is preformed to an inverted, V-shape so as to conform to the hip, ridge or rake portions of a roof. Various notches are formed on the perimeter of the top cover to facilitate longitudinal alignment and surface exposure of the shingles at installation. Depressions are formed on bottom surface of the substrate and are filled with an adhesive during manufacture. After installation, solar heat causes the adhesive to flow between the substrate and the subjacent area of the top cover, or roof, to provide wind uplift resistance.

2. A hip, ridge and rake shingle comprising:
-
a. a to cover including at least two panels bonded so as to form an integral piece, said integral piece being preformed into an inverted V-shape in cross-section and having a pair of side panels extending from a bendable median longitudinal peak to longitudinal bottom lateral edges, said side panels of said top cover sheet including a front end portion, a rear end portion, an upper surface and a lower surface; and
