Abstract

A laminated roofing shingle is disclosed comprising a posterior layer with tabs spaced apart by openings and an anterior layer with tabs spaced apart by openings, wherein the anterior layer is positioned offset from the posterior layer such that it partially overlaps the posterior layer in a manner such that the anterior layer does not entirely overlap the surface of the posterior tabs. A roofing system comprising a plurality of courses of the shingles is also disclosed as well as a method of manufacturing the shingle.

First claim

What is claimed is:

1. A two-layer laminated roofing shingle comprising:
(a) a posterior layer having a posterior top portion having a posterior upper edge and a posterior lower edge, and a posterior bottom portion including a plurality of posterior tabs extending from said posterior top portion along said posterior lower edge, said posterior tabs spaced apart to define a plurality of posterior openings between said posterior tabs;
(b) an anterior layer having an anterior top portion having an anterior upper edge and an anterior lower edge, and an anterior bottom portion including a plurality of anterior tabs extending from said anterior top portion along said anterior lower edge,
said anterior tabs spaced apart to define a plurality of anterior openings between said anterior tabs;
wherein the anterior layer is wider than the posterior layer;
wherein the anterior layer is positioned such that it partially overlaps the posterior layer such that the anterior tabs are positioned over the top portion of the posterior layer; wherein the shingle has only two layers; and
wherein front edges of the anterior tabs are vertically aligned with said posterior lower edge.

2. The roofing shingle according to claim 1 , wherein there is at least partial overlap between the top portion of the anterior layer and the top portion of the posterior layer.

3. The roofing shingle according to claim 1 , wherein the anterior layer and the posterior layer have the same length.

4. The roofing shingle according to claim 1 , wherein the number of posterior tabs and the number of anterior tabs is different.

5. The roofing shingle according to claim 1 , comprising five posterior tabs and six anterior tabs.

6. The roofing shingle according to claim 1 , comprising three posterior tabs and two anterior tabs.

7. The roofing shingle according to claim 1 , wherein the posterior tabs and the anterior tabs are horizontally offset.

8. The roofing shingle according to claim 1 , wherein the anterior tabs and the posterior openings are horizontally aligned.

9. The roofing shingle according to claim 1 , wherein the posterior tabs and posterior openings have no specific horizontal alignment with respect to the anterior tabs and anterior openings.

10. The roofing shingle according to claim 1 , 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.

11. The roofing shingle according to claim 1 , wherein at least one anterior tab has a first anterior tab height and at least another anterior tab has a second anterior tab height that differs from the first anterior tab height.

12. The roofing shingle according to claim 1 , wherein at least one anterior opening has a first anterior opening breadth and at least another anterior opening has a second anterior opening breadth that differs from the first anterior opening breadth.

13. The roofing shingle according to claim 1 , wherein at least one posterior tab has a first posterior tab breadth and at least another posterior tab has a second posterior tab breadth that differs from the first posterior tab breadth.

14. The roofing shingle according to claim 1 , wherein at least one posterior tab has a first posterior tab height and at least another posterior tab has a second posterior tab height that differs from the first posterior tab height.

15. The roofing shingle according to claim 1 , wherein at least one posterior opening has a first posterior opening breadth and at least another posterior opening has a second posterior opening breadth that differs from the first posterior opening breadth.

16. The roofing shingle according to claim 1 , wherein both the posterior layer and the anterior layer have a tab at one end of the shingle and an opening at the other end of the shingle such that the end opening of the anterior layer is at the opposite end of the shingle to the end opening of the posterior layer.

17. The roofing shingle according to claim 1 , wherein the posterior tab breadths and the anterior tab breadths are the same.

18. The roofing shingle according to claim 1 , wherein the posterior tab breadths and the anterior tab breadths are different.

19. The roofing shingle according to claim 1 , wherein the posterior tab heights and the anterior tab heights are the same.

20. The roofing shingle according to claim 1 , wherein the height of at least one posterior tab differs from the height of at least one anterior tab.

21. The roofing shingle according to claim 1 , wherein the posterior tab height is between about 40% and 50% of the posterior layer width.

22. The roofing shingle according to claim 1 , wherein the anterior tab height is between about 15% and 30% of the anterior layer width.

23. The roofing shingle according to claim 1 , wherein the posterior tab height is about 2.25 inches and the anterior tab height is about 2.25 inches.

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

25. The roofing shingle according to claim 1 , wherein each anterior tab, each anterior opening, each posterior tab and each posterior opening is a trapezoid.

26. The roofing shingle according to claim 1 , wherein the length of the shingle is about 39.375 inches.

27. The roofing shingle according to claim 1 , wherein the width of the shingle is about 13.25 inches.

28. The roofing shingle according to claim 1 , wherein the width of the posterior layer is between about 30% and 70% of the width of the anterior layer.

29. The roofing shingle according to claim 1 , wherein the width of the posterior layer is about 5.375 inches.

30. The roofing shingle according to claim 1 , wherein the width of the anterior layer is about 11 inches.

31. The roofing shingle according to claim 1 , wherein the posterior tabs and the anterior tabs are the same color.

32. The roofing shingle according to claim 1 , wherein the posterior tabs and the anterior tabs are different colors.

33. The roofing shingle according to claim 1 , wherein the anterior tabs are the same color as at least part of the anterior top portion.

34. The roofing shingle according to claim 1 , wherein the posterior tabs are the same color as at least part of the posterior top portion.

35. The roofing shingle according to claim 1 ,
wherein the length of the shingle is about 39.375 inches,
wherein the width of the shingle is about 13.25 inches,
wherein the posterior tab height is about 2.82 inches,
