Abstract

A system includes a plurality of roofing shingles installed on a roof deck. Each of the roofing shingles includes first and second ends, first and second edges, a head lap, a reveal portion, a first side lap at the first end, and a second side lap at the second end. The second side lap includes a first surface, which has an adhesive. The first side lap of a first one of the roofing shingles overlays and is attached to the second side lap of a second one of the roofing shingles to form a sealed portion between the head lap of the first one of the roofing shingles and the head lap of the second one of the roofing shingles.

First claim

What is claimed is:

1. A system, comprising:
a plurality of roofing shingles installed in at least a first row on a roof deck,
wherein each of the plurality of roofing shingles includes
a first end, a second end opposite the first end, a first edge extending from the first end to the second end, and a second edge opposite the first edge and extending from the first end to the second end,
a head lap extending from a first location between the first end and the second end to a second location between the first end and the second end,
a reveal portion extending from the first location to the second location,
a first side lap,
wherein the first side lap extends from the first end to the reveal portion at the first location and from the first edge to the second edge, and

a second side lap,
wherein the second side lap extends from the second end to the reveal portion at the second location and from the first edge to the second edge,
wherein the first side lap includes a first surface,
wherein at least a portion of the first surface includes an adhesive, and

wherein the second side lap of a first one of the plurality of roofing shingles in a first row of the at least a first row overlays and is attached to the first side lap of a second one of the plurality of roofing shingles in the first row from the first edge of the second one of the plurality of roofing shingles to the second edge of the second one of the plurality of roofing shingles.

2. The system of claim 1 , wherein the adhesive includes caulking.

3. The system of claim 1 , wherein the adhesive includes at least one adhesive strip.

4. The system of claim 3 , wherein the at least one adhesive strip is an adhesive tape.

5. The system of claim 4 , wherein the adhesive tape is butyl tape.

6. The system of claim 3 , wherein the at least one adhesive strip is a peel and stick film sheet.

7. The system of claim 1 , wherein the reveal portion includes at least one solar cell.

8. The system of claim 1 , wherein the head lap of each of the plurality of roofing shingles includes a plurality of grooves, each of which extends from a first end thereof, located proximate to the first edge and between the first end of a corresponding one of the plurality of roofing shingles and the second end of the corresponding one of the plurality of roofing shingles, to a second end thereof, located proximate to the first location, and wherein the head lap of the first one of the plurality of roofing shingles and the head lap of the second one of the plurality of roofing shingles form a seam therebetween, and wherein a longitudinal axis of each of the plurality of grooves does not intersect the seam.

9. The system of claim 8 , wherein each of the plurality of grooves extends 0 degrees to 45 degrees relative to the seam.

10. The system of claim 1 , wherein the second side lap includes a first end and a second end opposite the first end of the second side lap, a first edge extending from the first end of the second side lap to the second end of the second side lap, a second edge opposite the first edge of the second side lap and extending from the first end of the second side lap to the second end of the second side lap, and a plurality of grooves, and wherein the head lap of the first one of the plurality of roofing shingles and the head lap of the second one of the plurality of roofing shingles form a seam therebetween, and wherein a longitudinal axis of each of the plurality of grooves does not intersect the seam.

11. The system of claim 10 , wherein each of the plurality of grooves extends 0 degrees to 45 degrees relative to the seam.

12. A method, comprising:
obtaining a plurality of roofing shingles, each of the plurality of roofing shingles includes
a first end, a second end opposite the first end, a first edge extending from the first end to the second end, and a second edge opposite the first edge and extending from the first end to the second end,
a head lap extending from a first location between the first end and the second end to a second location between the first end and the second end,
a reveal portion extending from the first location to the second location,
a first side lap,
wherein the first side lap extends from the first end to the reveal portion at the first location and from the first edge to the second edge, and a second side lap,
wherein the second side lap extends from the second end to the reveal portion at the second location and from the first edge to the second edge,
wherein the first side lap includes a first surface and an adhesive on at least a portion of the first surface;

installing a first one of the plurality of roofing shingles on a roof deck; and
installing a second one of the plurality of roofing shingles on the roof deck,
wherein the first and second ones of the plurality of roofing shingles are installed in a first row on the roof deck, and
wherein the second side lap of the second one of the plurality of roofing shingles overlays and is attached to the first side lap of the first one of the plurality of roofing shingles from the first edge of the second one of the plurality of roofing shingles to the second edge of the second one of the plurality of roofing shingles.

13. The method of claim 12 , wherein the adhesive includes caulking.

14. The method of claim 12 , wherein the adhesive includes at least one adhesive strip.

15. The method of claim 14 , wherein the at least one adhesive strip is an adhesive tape.

16. The method of claim 15 , wherein the adhesive tape is butyl tape.

17. The method of claim 14 , wherein the at least one adhesive strip is a peel and stick film sheet.

18. The method of claim 12 , wherein the reveal portion includes at least one solar cell.

19. A system, comprising:
a plurality of roofing shingles installed on a roof deck,
wherein each of the plurality of roofing shingles includes
a first end, a second end opposite the first end, and a first edge extending from the first end to the second end,
a head lap extending from a first location between the first end and the second end to a second location between the first end and the second end,
wherein the head lap of each of the plurality of roofing shingles includes a plurality of grooves, each of which extends from a first end thereof, located proximate to the first edge and between the first end of a corresponding one of the plurality of roofing shingles and the second end of the corresponding one of the plurality of roofing shingles, to a second end thereof, located proximate to the first location,

a reveal portion extending from the first location to the second location,
wherein the reveal portion includes a first width,
wherein each of the plurality of grooves includes a second width,
wherein the second width is 10% to 100% of the first width,

a first side lap at the first end, and
a second side lap at the second end,
wherein the second side lap of a first one of the plurality of roofing shingles overlays and is attached to the first side lap of a second one of the plurality of roofing shingles,
wherein a seam is located between the head lap of the first one of the plurality of roofing shingles and the head lap of the second one of the plurality of roofing shingles, and
wherein a longitudinal axis of each of the plurality of grooves does not intersect the seam.

20. A system, comprising:
a plurality of roofing shingles installed on a roof deck,
wherein each of the plurality of roofing shingles includes
a first end, a
