Process of producing hip, ridge or rake shingles, and high profile shingles produced thereby

A high profile hip, ridge or rake shingle having a tab portion and a butt portion, with the tab portion and the butt portion meeting at a junction, the shingle comprising:

• (a) a posterior shingle layer of a first length and having a leading edge and a trailing edge;
• (b) an anterior shingle layer of a second length, shorter than said first length, adhesively secured to said posterior layer and having a leading edge and a trailing edge, with the trailing edge of the anterior layer being spaced from the trailing edge of the posterior layer, leaving a first step on the posterior layer uncovered by said anterior layer;
• (c) a first riser being of a third length and adhesively secured to said anterior layer and having a leading edge and a trailing edge, with its leading edge being at the junction of the shingle butt and tab portions and with its trailing edge being spaced from the trailing edge of the anterior layer, leaving a second step on the anterior layer uncovered by the first riser;
• (d) a second riser being of a fourth length and adhesively secured to said first riser and having a leading edge and a trailing edge, with its leading edge being at the junction of the shingle butt and tab portions and its trailing edge being spaced from the trailing edge of the first riser, leaving a third step on the first riser uncovered by said second riser and with a top surface of the second riser comprising a fourth step;
• (e) with said first, second, third and fourth steps together, comprising a progressive, decreasing stepped wedge-like thickness of the butt portion of the shingle, for receiving a tab portion of a next-overlying shingle thereover, wherein the posterior shingle layer has a first width and the anterior shingle layer has a second width, said first width being less than the second width.

• (e) with said first, second, third and fourth steps together, comprising a progressive, decreasing stepped wedge-like thickness of the butt portion of the shingle, for receiving a tab portion of a next-overlying shingle thereover, including a line of adhesive between the posterior layer and the anterior layer, connected to only one of the surfaces of said anterior and posterior layers, and with a removable release strip between the line of adhesive and a surface of one of the anterior and posterior layers, to allow sliding movement between the anterior and posterior layers when the shingle is bent about an imaginary line generally parallel to said release strip wherein the posterior shingle layer has a first width and the anterior shingle layer has a second width, said first width being less than the second width.
