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 feature is adapted to permit alignment of adjacent roofing shingles during installation on a roof.

First claim

The invention claimed is:

1. A roofing shingle, comprising:
a lowermost layer including a headlap and a plurality of tabs extending equidistant from the headlap, wherein adjacent tabs are divided by slits that extend from a butt end of the lowermost layer and at least to the headlap, wherein the lowermost layer comprises an upper surface and a lower surface, wherein the lowermost layer is a single layer in the roofing shingle devoid of additional layers adhered to the lower surface such that the lower surface defines a back of the roofing shingle and wherein the width of the lowermost layer is measured perpendicular to a butt end of the lowermost layer; and
a plurality of fingers adhered to the upper surface of the lowermost layer and entirely disconnected from one another such that no part of one finger contacts another finger, wherein each of the plurality of fingers is disposed on and centered along one tab of the plurality of tabs;
wherein a first finger of the plurality of fingers extends from the butt end of the lowermost layer and does not extend along the full width of the lowermost layer;
wherein a second finger of the plurality of fingers extends an entire width of the lowermost layer; and
wherein a third finger of the plurality of fingers does not extend along the full width of the lowermost layer and extends beyond the butt end of the lowermost layer, such that it overhangs the butt end of the lowermost layer.

2. The roofing shingle of claim 1 , further comprising a longitudinal reinforcement material that is thinner than the lowermost layer, wherein the reinforcement material is coupled to an exterior surface of the shingle, and wherein the reinforcement material extends between opposite lateral edges of the shingle.

3. The roofing shingle of claim 2 , wherein the shingle further comprises a longitudinal fastening zone which is between a right edge and a left edge of the shingle and between an upper edge and the butt end of the lowermost layer, and wherein the reinforcement material is at least partially in the fastening zone.

4. The roofing shingle of claim 1 , wherein at least one of the plurality of fingers comprises a layered construction including at least two layers coupled together.

5. The roofing shingle of claim 4 , wherein at least two of the at least two layers coupled together have different widths, lengths, thicknesses, or a combination thereof.

6. The roofing shingle of claim 1 , wherein each of the plurality of fingers has a rectangular profile.

7. The roofing shingle of claim 1 , wherein a fourth finger of the plurality of fingers is disposed entirely within the headlap of the lowermost layer.
