Abstract

A laminated roofing shingle is disclosed comprising a posterior layer with tabs and an anterior layer with tabs spaced apart by openings, wherein each posterior tab is partially covered by a corresponding anterior tab, wherein at least one anterior tab has a first anterior tab breadth and at least another anterior tab has a second anterior tab breadth, and wherein at least one anterior opening has a first anterior opening breadth that is about equal to the second anterior tab breadth and wherein at least another anterior opening has a second anterior opening breadth that is about equal to the first anterior tab breadth. Also disclosed is a roofing system comprising a plurality of courses of the shingle.

First claim

1 . A two layer laminated roofing shingle comprising:
(a) a posterior layer having a posterior headlap portion and a posterior buttlap portion including a plurality of posterior tabs extending from said posterior headlap portion, said posterior tabs spaced apart to define a plurality of posterior openings between said posterior tabs; (b) an anterior layer having an anterior headlap portion and an anterior buttlap portion including a plurality of anterior tabs extending from said anterior headlap portion, said anterior tabs spaced apart to define a plurality of anterior openings between said anterior tabs; and wherein the anterior layer is positioned on the posterior layer in a manner such that each posterior tab has an anterior tab positioned thereon; wherein the number of posterior tabs is equal to the number of anterior tabs; wherein the posterior tabs have a given breadth that is about equal for each posterior tab; wherein at least one anterior tab has a first anterior tab breadth and at least another anterior tab has a second anterior tab breadth that differs from the first anterior tab breadth; wherein at least one anterior opening has a first anterior opening breadth that is about equal to the second anterior tab breadth; and wherein at least another anterior opening has a second anterior opening breadth that is about equal to the first anterior tab breadth; such that each posterior tab is at least partially covered with an anterior tab to achieve the appearance of a shine having at least one posterior tab that is not covered by an anterior tab.

2 . The roofing shingle according to claim 1 ,
wherein at least one anterior tab has a first anterior tab breadth that is less than 50% the breadth of each posterior tab; wherein at least another anterior tab has a second anterior tab breadth that is 50% or more, but less than 100%, the breadth of each posterior tab; and wherein each anterior tab does not extend over any said posterior opening.

3 . The roofing shingle according to claim 1 , wherein the shingle has no alignment notch in the anterior headlap.

4 . The roofing shingle according to claim 1 , comprising four posterior tabs and four anterior tabs.

5 . The roofing shingle according to claim 1 , wherein the first anterior tab breadth is about 50% the breadth of the second anterior tab breadth.

6 . The roofing shingle according to claim 1 , wherein each anterior tab has right angle corners and each anterior opening has right angle corners.

7 . The roofing shingle according to claim 1 , wherein each anterior tab has crimped corners and each anterior opening has crimped corners.

8 . The roofing shingle according to claim 1 , wherein each anterior tab has non-straight irregular edge contours.

9 . The roofing shingle according to claim 1 , wherein each posterior tab has right angle corners and each posterior opening has right angle corners.

10 . The roofing shingle according to claim 1 , wherein each posterior tab has crimped corners.

11 . The roofing shingle according to claim 1 , wherein each anterior tab has an edge contour selected from the group consisting of stair-stepped, trapezoidal, angular,
curved or jagged edge contours.

12 . The roofing shingle according to claim 1 , wherein the first anterior tab breadth is about 2.88 inches and the second anterior tab breadth is about 5.75 inches, and the breadth of the posterior tabs is about 8.25 inches.

13 . The roofing shingle according to claim 1 , wherein the shingle is a two-layer laminated roofing shingle.

14 . A roofing system comprising at least four adjacent shingles, each of first, second, third, and fourth adjacent shingles comprising:
(a) a posterior layer having a posterior headlap portion and a posterior buttlap portion including four posterior tabs extending from said posterior headlap portion, said posterior tabs spaced apart to define a plurality of posterior openings between said posterior tabs; (b) an anterior layer having an anterior headlap portion and an anterior buttlap portion including four anterior tabs extending from said anterior headlap portion, said anterior tabs spaced apart to define a plurality of anterior openings between said anterior tabs; wherein the anterior layer is positioned on the posterior layer in a manner such that each anterior tab is positioned over a posterior tab; wherein the posterior tabs have a given breadth that is about equal for each posterior tab; wherein at least one anterior tab has a first anterior tab breadth that is less than 50% the breadth of each posterior tab; wherein at least another anterior tab has a second anterior tab breadth that is 50% or more, but less than 100% the breadth of each posterior tab; wherein each of the first, second, and third adjacent shingles differ from each other based on the positions of the at least one anterior tab having the first anterior tab breadth and the at least another anterior tab having the second anterior tab breadth; and wherein the first adjacent shingle and the fourth adjacent shingle are identical based on the positions of the at least one anterior tab having the first anterior tab breadth and the at least another anterior tab having the second anterior tab breadth, so that when installed, a pattern of varying anterior tab breadths is created based on the respective positions of the anterior tabs having the first anterior tab breadth and the anterior tabs having the second anterior tab breadth.

15 . The roofing system of claim 14 , wherein at least one of the at least four adjacent shingles has two anterior tabs having said first anterior tab breadth and two anterior tabs having said second anterior tab breadth.

16 . The roofing system of claim 14 , wherein at least one of the at least four adjacent shingles has one anterior tab having said first anterior tab breadth and three anterior tabs having said second anterior tab breadth.

17 . The roofing system of claim 14 , wherein at least one of the at least four adjacent shingles has three anterior tabs having said first anterior tab breadth and one anterior tab having said second anterior tab breadth.

18 . A roofing system comprising a plurality of courses of shingles according to claim 1 , wherein the shingles are installed on a roof deck in overlapping courses.

19 . A two layer laminated roofing shingle including a posterior layer and an anterior layer formed from cutting cylinders, said shingle comprising:
(a) said posterior layer having a posterior headlap portion and a posterior buttlap portion including a plurality of posterior tabs extending from said posterior headlap portion, said posterior tabs spaced apart to define a plurality of posterior openings between said posterior tabs; (b) said anterior layer having an anterior headlap portion and an anterior buttlap portion including a plurality of anterior tabs extending from said anterior headlap portion, said anterior tabs spaced apart to define a plurality of anterior openings between said anterior tabs; and wherein the anterior layer is positioned on the posterior layer in a manner such that each posterior tab has an anterior tab positioned thereon; such that each posterior tab is at least partially covered with an anterior tab to achieve the appearance of a shingle having at least one posterior tab that is not covered by an anterior tab; wherein each anterior tab extends over no posterior opening; wherein the number of posterior tabs is equal to the number of anterior tabs; wherein said roofing shingle has a length; wherein
