wherein the posterior simulated tabs are surfaced with a first shade of granules and the connecting segments are surfaced with a second shade of granules that is darker than said first shade of granules.
3. A roofing shingle comprising:
a headlap and a buttlap including a plurality of simulated tabs extending from said headlap, said simulated tabs spaced apart by a plurality of partial slots, and each simulated tab is connected to at least one adjacent simulated tab by a connecting segment; and
wherein the simulated tabs are surfaced with a first shade of granules and the connecting segments are surfaced with a second shade of granules that is darker than said first shade of granules.
4. The roofing shingle according to claim 1 , 2 or 3 , wherein the connecting segment is located at or near the lower edge of the buttlap.
5. The roofing shingle according to claim 4 , wherein the connecting segment has a height of about 1 inch.
6. A roofing system comprising a plurality of courses of shingles according to claim 1 , 2 or 3 , wherein the shingles are installed on a roof deck in overlapping courses.
7. A roofing system comprising a plurality of courses of shingles according to claim 2 , wherein the shingles are installed on a roof deck in overlapping courses, wherein first, second, and third adjacent shingles differ from each other based on the position of at least one anterior tab, and wherein the first adjacent shingle and the fourth adjacent shingle in a course are identical based on the positions of the one or more anterior tabs and the at least one alignment notch, so that when installed, a pattern of varying anterior tabs is created based on the locations of the anterior tabs and the at least one alignment notch.
8. A roofing system comprising a plurality of courses of shingles according to claim 2 , wherein the shingles are installed on a roof deck in overlapping courses, wherein first, second, third, fourth, and fifth adjacent shingles differ from each other based on the position of at least one anterior tab, and wherein the first adjacent shingle and the sixth adjacent shingle in a course are identical based on the positions of the one or more anterior tabs and the at least one alignment notch, so that when installed, a pattern of varying anterior tabs is created based on the locations of the anterior tabs and the at least one alignment notch.
9. A roofing system comprising a plurality of courses of shingles according to claim 2 , wherein the shingles are installed on a roof deck in overlapping courses, wherein first, second, third, fourth, fifth, sixth, and seventh adjacent shingles differ from each other based on the position of at least one anterior tab, and wherein the first adjacent shingle and the eighth adjacent shingle in a course are identical based on the positions of the one or more anterior tabs and the at least one alignment notch, so that when installed, a pattern of varying anterior tabs is created based on the locations of the anterior tabs and the at least one alignment notch.
10. The roofing shingle according to claim 2 , wherein the anterior headlap comprises one anterior tab extending therefrom, and three alignment notches positioned on the lower edge of the anterior headlap.
11. The roofing shingle according to claim 2 , wherein the anterior headlap comprises two anterior tabs extending therefrom, and two alignment notches positioned on the lower edge of the anterior headlap.
12. The roofing shingle according to claim 2 , wherein the anterior headlap comprises three anterior tabs extending therefrom, and one alignment notch positioned on the lower edge of the anterior headlap.
13. The roofing shingle according to claim 2 , wherein:
the at least one anterior tab further comprises granules having the second shade;
the posterior layer further comprises a shadow band positioned at an interface between the posterior simulated tabs and the posterior headlap;
the posterior simulated tabs further comprise a shadow tip positioned on a lower edge of the posterior simulated tabs;
the shadow tip and shadow band include granules having a third shade that is darker than said first shade of granules of the posterior simulated tabs and the second shade of granules of the at least one anterior tab and the connecting segments.
14. The roofing shingle according to claim 2 , wherein the at least one anterior tab has a first breadth and the posterior simulated tabs have a second breadth, and wherein the second breadth is greater than the first breadth.
15. The roofing shingle according to claim 2 , wherein the posterior simulated tabs are separated by partial slots having a breadth of from about ¼″ to about 1 inch.
