Abstract

A roofing system including shingles with different shingle patterns. The roofing system may include a plurality of first shingles having a first two-tab shingle pattern and a plurality of second shingles having a second two-tab shingle pattern. The first shingles including a first tab having a first width and a second tab having a second width, wherein the first width and the second width are substantially equal. The second shingles including a third tab having a third width and a fourth tab having a fourth width, wherein the third width is substantially equal to the first width and the fourth width is about double the second width. The plurality of first shingles and the plurality of second shingles can be formed from a rectangular shingle blank in an interwoven pattern with substantially no scrap or waste material.

First claim

The invention claimed is:

1. A roofing system, comprising:
a plurality of first shingles having two tabs arranged in a first two-tab shingle pattern including a first tab having a first width spaced apart from a second tab having a second width by a first cutout having a first cutout width substantially equal to the first width, wherein the first width and the second width are substantially equal; and
a plurality of second shingles having two tabs arranged in a second two-tab shingle pattern including a third tab having a third width spaced apart from a fourth tab having a fourth width by a second cutout having a second cutout width substantially equal to the third width, wherein the third width is substantially equal to the first width and the fourth width is about double the second width;
wherein the plurality of first shingles and the plurality of second shingles can be formed from a rectangular shingle blank in an interwoven pattern with substantially no scrap or waste material.

2. The roofing system of claim 1 , wherein the first cutout is centered on a centerline of the first shingle and the second cutout is centered on a centerline of the second shingle.

3. The roofing system of claim 1 , further comprising a third shingle having two tabs arranged in a third two-tab shingle pattern including a fifth tab having a fifth width and a sixth tab having a sixth width, wherein the fifth width is substantially equal to the first width and the sixth width is about 1.5 times the second width.

4. The roofing system of claim 3 , wherein the third shingle includes a third cutout separating the fifth tab and the sixth tab, the third cutout having a third cutout width that is substantially equal to the first cutout width.

5. The roofing system of claim 4 , wherein the third cutout is centered on a centerline of the third shingle.

6. The roofing system of claim 3 , wherein the interwoven pattern includes a first lane of shingles and a second lane of shingles, wherein the first lane of shingles has alternating shingles of the first and third shingles and the second lane has alternating shingles of the second and third shingles.

7. The roofing system of claim 1 , wherein the interwoven pattern includes a first lane of shingles and a second lane of shingles, wherein the first and second lane of shingles have alternating shingles of the first and second shingles.

8. The roofing system of claim 1 , wherein each of the plurality of first shingles has a total width and the first width is substantially one-fifth of the total width.

9. A roofing shingle system for covering a roof, comprising:
a plurality of first shingles having two tabs arranged in a first two-tab shingle pattern including a head portion and a tab portion, the tab portion including a series of tabs and cutouts separating the tabs;
a plurality of second shingles having two tabs arranged in a second two-tab shingle pattern different than the first shingle pattern, the second shingle pattern including a head portion and a tab portion, the tab portion including a series of tabs and cutouts separating the tabs;
a plurality of third shingles having two tabs arranged in a third two-tab shingle pattern different than the first shingle pattern and the second shingle pattern, the third shingle pattern including a head portion and a tab portion, the tab portion including a series of tabs and cutouts separating the tabs;
a first course of shingles arranged on the roof including a random selection of the first, second, and third shingles arranged side-by-side to form edge joints between the shingles; and
a second course of shingles arranged on the roof deck overlaying the head portions of the first, second, or third shingles on the first course, the second course of shingles including a random selection of the first, second, and third shingles arranged side-by-side;
wherein at least one of the tabs of the first shingle, at least one of the tabs of the second shingle, and at least one of the tabs of the third shingle all have a tab width that is the same;
wherein at least one of the cutouts of the first shingle, at least one of the cutouts of the second shingle, and at least one of the cutouts of the third shingle all have a width equal to the tab width; and
wherein regardless of the random order of the first course of shingles and the second course of shingles, the edge joints in the first course of shingles are covered by a tab on a shingle in the second course of shingles.

10. The roofing system of claim 9 , wherein the second course of shingles includes tabs of a first width and tabs of a second width, and a sidelap distance between an edge of a shingle of the first course and an edge of a shingle of the second course is equal to about half of the smaller of the first width and the second width.
