Abstract

A shingle comprises an overlay, an underlay, and a height increasing material disposed between the overlay and the underlay. The height increasing material includes a first adhesive adhered to the overlay, height increasing granules adhered to the first adhesive, and a second adhesive adhered to the height increasing granules and the underlay. The height increasing material can extend along front ends of tab portions of the overlay, along front cutout edges that extend between tab portions of the overlay, or both.

First claim

The invention claimed is:

1. A roofing material, comprising:
an overlay layer having a headlap portion and a tab portion, wherein the headlap portion comprises a top headlap edge and a bottom headlap edge, wherein the tab portion comprises a top tab edge and a bottom tab edge, and wherein the overlay layer has a first height that extends from the top headlap edge to the bottom tab edge;
an underlay layer having a second height that extends from a top underlay edge to a bottom underlay edge, wherein the second height is less than the first height of the overlay layer; and
an intermediate layer positioned between the underlay layer and the overlay layer, wherein the intermediate layer comprises a rectangular strip that increases a thickness of the roofing material;
wherein the intermediate layer is positioned between the top underlay edge and the bottom headlap edge; and
wherein a bottom edge of the intermediate layer is colinear with the bottom headlap edge of the headlap portion of the overlay layer.

2. The roofing material according to claim 1 , wherein the intermediate layer is attached to the overlay layer and the underlay layer by an adhesive.

3. The roofing material according to claim 1 , wherein a top edge of the intermediate layer is colinear with the top underlay edge of the underlay layer.

4. The roofing material according to claim 1 , wherein the tab portion of the overlay layer comprises a plurality of tabs that are defined by the top tab edge that is adjacent to the bottom headlap edge of the headlap portion.

5. The roofing material according to claim 1 , wherein the intermediate layer extends under an entire width of the headlap portion of the overlay layer.

6. The roofing material according to claim 1 , wherein a height between a bottom edge of the intermediate layer and a top edge of the intermediate layer is between 0.5 inches and 2 inches.

7. The roofing material according to claim 1 , wherein the overlay layer comprises a reinforced nail zone, and wherein the intermediate layer extends under at least a portion of the reinforced nail zone.

8. The roofing material according to claim 1 , wherein the overlay layer comprises an alignment guide to assist in aligning an adjacent roofing material, and wherein a top edge of the intermediate layer is aligned with the alignment guide.

9. The roofing material according to claim 1 , wherein the rigid substrate of the intermediate layer comprises one of a glass fiber mat or an organic felt.

10. The roofing material according to claim 1 , wherein the intermediate layer has a uniform thickness.

11. A roofing material, comprising:
an overlay layer having a headlap portion and a tab portion, wherein the headlap portion comprises a top headlap edge and a bottom headlap edge, wherein the tab portion comprises a plurality of tabs that are defined by a top tab edge that is adjacent to the bottom headlap edge;
an underlay layer having a top underlay edge and a bottom underlay edge; and
an intermediate layer positioned between the underlay layer and the overlay layer, wherein the intermediate layer comprises a rectangular strip that increases a thickness of the roofing material;
wherein a top edge of the intermediate layer is colinear with the top underlay edge of the underlay layer; and
wherein a bottom edge of the intermediate layer is colinear with the bottom headlap edge of the headlap portion of the overlay layer.

12. The roofing material according to claim 11 , wherein the rigid substrate of the intermediate layer comprises one of a glass fiber mat or an organic felt.

13. The roofing material according to claim 11 , wherein the intermediate layer has a uniform thickness.

14. The roofing material according to claim 11 , wherein the intermediate layer is attached to the overlay layer and the underlay layer by an adhesive.

15. The roofing material according to claim 11 , wherein the intermediate layer extends under an entire width of the headlap portion of the overlay layer.

16. The roofing material according to claim 11 , wherein a height between the bottom edge of the intermediate layer and the top edge of the intermediate layer is between 0.5 inches and 2 inches.

17. The roofing material according to claim 11 , wherein the overlay layer comprises a reinforced nail zone, and wherein the intermediate layer extends under at least a portion of the reinforced nail zone.

18. The roofing material according to claim 11 , wherein the overlay layer comprises an alignment guide to assist in aligning an adjacent roofing material, and wherein the top edge of the intermediate layer is aligned with the alignment guide.
