Abstract

A system includes a plurality of photovoltaic shingles and a plurality of roofing shingles installed on a roof deck. Each of the roofing shingles includes a headlap portion and a nail zone on the headlap portion. The nail zone includes at least one nail receiving portion, and at least one opening defining a perimeter of at least a portion of the at least one nail receiving portion. Each of the roofing shingles is installed on the roof deck by at least one fastener, which extends through the at least one nail receiving portion.

Claims (58)

1. A system, comprising:

a plurality of photovoltaic shingles installed on a roof deck; and

a plurality of roofing shingles installed on the roof deck proximate the plurality of photovoltaic shingles,

wherein each of the plurality of roofing shingles includes

a headlap portion,

wherein the headlap portion includes an upper surface and a lower surface opposite the upper surface, and

a nail zone on the headlap portion,

wherein the nail zone includes

 at least one nail receiving portion, and

 at least one opening defining a perimeter of at least a portion of the at least one nail receiving portion,

 wherein the at least one opening extends from the upper surface to the lower surface,

 wherein each of the plurality of roofing shingles is installed on the roof deck by at least one fastener, and

 wherein the at least one fastener extends through the at least one nail receiving portion.

2. The system of claim 1 , wherein the at least one opening comprises a plurality of openings.

3. The system of claim 1 , wherein the at least one opening comprises at least a first opening and a second opening.

4. The system of claim 1 , wherein the at least one nail receiving portion has a circular shape.

5. The system of claim 4 , wherein the at least one opening includes a first plurality of openings arranged in a first circular pattern.

6. The system of claim 5 , wherein the at least one opening includes a second plurality of openings arranged in a second circular pattern, and wherein the first circular pattern and the second circular pattern are concentric with one another.

7. The system of claim 6 , wherein the second circular pattern surrounds the first circular pattern, and wherein the first circular pattern surrounds the at least one nail receiving portion.

8. The system of claim 6 , wherein each of the first plurality of openings and each of the second plurality of openings is arcuate-shaped.

9. The system of claim 6 , wherein the at least one opening includes a third plurality of openings arranged in a third circular pattern, and wherein the first circular pattern, the second circular pattern, and the third circular pattern are concentric with one another.

10. The system of claim 9 , wherein the third circular pattern surrounds the second circular pattern.

11. The system of claim 5 , wherein the at least one nail receiving portion is on the upper surface.

12. The system of claim 1 , wherein each of the plurality of roofing shingles is composed of a polymer.

13. The system of claim 12 , wherein each of the plurality of roofing shingles is composed of thermoplastic polyolefin (TPO).

14. The system of claim 1 , wherein each of the plurality of roofing shingles is composed of metal.

15. A system, comprising:

a plurality of photovoltaic shingles installed on a roof deck; and

a plurality of roofing shingles installed on the roof deck proximate the plurality of photovoltaic shingles,

wherein each of the plurality of roofing shingles includes

a headlap portion,

wherein the headlap portion includes an upper surface and a lower surface opposite the upper surface, and

a plurality of ribs on the headlap portion, and

a nail zone on the headlap portion proximate to the plurality of ribs,

wherein the nail zone includes

 at least one nail receiving portion, and

 at least one opening defining a perimeter of at least a portion of the at least one nail receiving portion,

 wherein the at least one opening extends from the upper surface to the lower surface,

 wherein each of the plurality of roofing shingles is installed on the roof deck by at least one fastener, and

 wherein the at least one fastener extends through the at least one nail receiving portion.

16. The system of claim 15 , wherein the at least one opening comprises a plurality of openings.

17. The system of claim 16 , wherein the first plurality of openings is arranged in a first circular pattern.

18. A system, comprising:

a plurality of photovoltaic shingles installed on a roof deck; and

a plurality of roofing shingles installed on the roof deck proximate the plurality of photovoltaic shingles,

wherein each of the plurality of roofing shingles includes

an upper surface and a lower surface,

a headlap portion, and

a nail zone on the headlap portion,

wherein the nail zone includes

 at least one nail receiving portion,

 at least one opening defining at least a first portion of a perimeter of at least a first portion of the at least one nail receiving portion,

 wherein the at least one opening extends from the upper surface to the lower surface, and

 at least one embossed portion within the upper surface defining at least a second portion of the perimeter of at least a second portion of the at least one nail receiving portion,

 wherein each of the plurality of roofing shingles is installed on the roof deck by at least one fastener, and

 wherein the at least one fastener extends through the at least one nail receiving portion.

19. The system of claim 18 , wherein the at least one opening comprises a plurality of openings.

20. The system of claim 19 , wherein the first plurality of openings is arranged in a first circular pattern.
