Abstract

A roofing shingle including a lower layer including a headlap and a plurality of tabs extending from the headlap, and an upper layer including one or more fingers, wherein the one or more fingers are disconnected from one another, and wherein each of the one or more fingers is disposed on one tab of the plurality of tabs, wherein a number of the plurality of tabs is different than a number of the one or more fingers. In an embodiment, the lower layer is a lowermost layer of the roofing shingle. In another embodiment, the roofing shingle further includes an alignment feature disposed in an exposure zone of the roofing shingle, wherein the alignment features is adapted to permit alignment of adjacent roofing shingles during installation on a roof.

First claim

What is claimed is:

1. A roofing shingle, comprising: a lower layer including a headlap and a plurality of tabs extending from the headlap; and an upper layer including a plurality of fingers,
wherein the plurality of fingers are disconnected from one another,
wherein the total number of the plurality of tabs is different than the total number of the plurality of fingers
wherein the roofing shingle has an exposure zone extending between a butt end of the shingle and the headlap of the lower layer, wherein a shadow formation is disposed in the exposure zone, the shadow formation having a different color than the remaining portions of the exposure zone, and wherein the shadow formation does not extend into the headlap portion of the lower layer,
wherein at least one finger of the plurality of fingers extends from the headlap to a butt end of one of the plurality of tabs, and
wherein the at least one finger of the plurality of fingers extends across the shingle a distance less than a width of the shingle.

2. The roofing shingle of claim 1 , wherein the shadow formation and the remaining exposure zone differ from each other in color by at least about 2 L*CIE color units and not greater than about 50 L*CIE color units.

3. The roofing shingle of claim 1 , wherein at least a portion of the lower layer comprises a first type of granule, and wherein at least a portion of the upper layer comprises a second type of granule that differs from the first type of granule.

4. The roofing shingle of claim 3 , wherein the alignment feature comprises a third type of granule that differs from the second type of granule.

5. The roofing shingle of claim 1 , further comprising: an alignment feature disposed in the exposure zone of the roofing shingle, wherein the alignment features is adapted to permit alignment of adjacent roofing shingles during installation on a roof.

6. The roofing shingle of claim 5 , wherein at least one of the one or more fingers comprises the alignment feature.

7. The roofing shingle of claim 5 , wherein the alignment feature comprises at least one of the one or more fingers.

8. The roofing shingle of claim 5 , wherein the alignment feature is disposed on the one or more disconnected fingers.

9. The roofing shingle of claim 5 , wherein the alignment feature extends into a hidden zone of the roofing shingle such that at least a portion of the alignment feature is covered in the installed state.

10. The roofing shingle of claim 5 , wherein the roofing shingle defines an X-direction parallel with a width of the roofing shingle and a Y-direction parallel with a length of the roofing shingle, and wherein the alignment feature is adapted to align adjacent roofing shingles in at least one of the X- and Y-directions.

11. The roofing shingle of claim 5 , wherein a thickness of the alignment feature is no greater than a thickness of the lower layer, the upper layer, or both.

12. The roofing shingle of claim 1 , further comprising: an impact resistant material coupled with the lower layer.

13. The roofing shingle of claim 12 , wherein the impact resistant material comprises a scrim, fabric, mesh, film, paper, foil, or any combination thereof.

14. The roofing shingle of claim 1 , further comprising: an at least partially exposed generally longitudinal reinforcement material of a substantially thinner dimension as compared to the lower layer, wherein the reinforcement material is coupled to an exterior surface of the shingle and extends at least substantially between opposite lateral edges of the shingle.

15. The roofing shingle of claim 14 , wherein the shingle further comprises a longitudinal fastening zone between a right edge and a left edge of the shingle, generally intermediate an upper edge and the butt end of the shingle, the reinforcement feature being at least partially lower than the fastening zone, toward the butt end of the shingle or at least partially in the fastening zone toward the upper edge of the shingle.

16. The roofing shingle of claim 15 , wherein the reinforcement material is coupled to a front exterior surface of the shingle.

17. The roofing shingle of claim 15 , wherein the reinforcement material is coupled to a rear exterior surface of the lower layer.

18. The roofing shingle of claim 15 , wherein the reinforcement material is coupled to a rear exterior surface of the shingle.

19. The roofing shingle of claim 1 , wherein the at least one finger extends no greater than 99% of the width of the shingle.

20. The roofing shingle of claim 1 , wherein all of the shingles extend across the shingle a distance less than the width of the shingle.
