There is provided a hip, ridge, or rake shingle, which includes a shingle panel and at least one rigid back member. The shingle panel has a substantially planar lower surface. The at least one rigid back member has a length substantially the same as or greater than the length of the shingle panel. The rigid back member is attached to the substantially planar lower surface of the shingle panel. The rigid back member includes a step in thickness in a cross-sectional plane perpendicular to the substantially planar lower surface and parallel to the longitudinal axis of the rigid back member. In addition, the thickness of the rigid back member at the high level of the step is greater than the thickness of the rigid back member at one of its ends. There is also provided an asphaltic adhesive including from about 62% to about 99% by weight of an asphalt cement; from about 0.5% to about 15% by weight of a first thermoplastic having a glass-transition temperature in the range from about 190&deg; F. to about 260&deg; F.; and from about 0.5% to about 15% by weight of a second thermoplastic having a glass-transition temperature in the range from about &minus;55&deg; F. to about 0&deg; F.

Aesthetic, self-aligning shingle for hip, ridge, or rake portion of a roof

There is provided a hip, ridge, or rake shingle, which includes a shingle panel and at least one rigid back member. The shingle panel has a substantially planar lower surface. The at least one rigid back member has a length substantially the same as or greater than the length of the shingle panel. The rigid back member is attached to the substantially planar lower surface of the shingle panel. the rigid back member includes a step in thickness in a cross-sectional plane perpendicular to the substantially planar lower surface and parallel to the longitudinal axis of the rigid back member. In addition, the thickness of the rigid back member at the high level of the step is greater than the thickness of the rigid back member at one of its ends. There is also provided an asphaltic adhesive including from about 62% to about 99% by weight of an asphalt cement; from about 0.5% to about 15% by weight of a first thermoplastic having a glass-transition temperature in the range from about 190&deg; F. to about 260&deg; F.; and from about 0.5% to about 15% by weight of a second thermoplastic having a glass-transition temperature in the range from about &minus;55&deg; F. to about 0&deg; F.

There is provided a laminated roofing shingle having a first shingle sheet and a second shingle sheet. The first shingle sheet has a headlap section and a buttlap section, the buttlap section being about 7 inches or greater in height and including a plurality of tabs which are spaced apart to define one or more openings between the tabs. Each of the tabs has a relatively uniform color throughout the tab. The second shingle sheet is attached to the underside of the first shingle sheet and has portions exposed through the openings between the tabs. The second shingle sheet has at least first, second, third, and fourth horizontal striations thereon across at least partial portions of the second sheet which are exposed through the openings between the tabs. The first striation includes a first elongated quadrilateral area with a substantially uniform dark color throughout the first quadrilateral area. The second striation includes a second elongated quadrilateral area below the first striation. The second striation has a substantially uniform color throughout the second quadrilateral area. The third striation includes a third elongated quadrilateral area below the second striation. The third striation has a substantially uniform color throughout the third quadrilateral area, which is lighter than the color of the second striation. The fourth striation includes a fourth elongated quadrilateral area below the third striation. The fourth striation has a substantially uniform color throughout the fourth quadrilateral area, which is lighter than the color of the third striation. There are also provided methods for manufacturing the above-described laminated shingle.
