The roofing shingle according to claim 1, wherein the buttlap portion is further surfaced with a third further contrasting shade of granules on the buttlap projections. 3. The roofing shingle according to claim 1, wherein the maximum headlap width is approximately 60% of the maximum buttlap width. 4. The roofing shingle according to claim 1, wherein the buttlap projections have a height of about 2 inches. 5. The roofing shingle according to claim 4, wherein the headlap projections have a height of about 1¾ inches. 6. The roofing shingle according to claim 1, wherein the breadth of the first projected horizontal headlap portion nearest to the lateral leading edge is about 125% the primary horizontal breadth. 7. The roofing shingle according to claim 1, wherein the primary horizontal breadth is about 6 inches. 8. The roofing shingle according to claim 1, wherein at least one of said buttlap projections has a shape that mirrors one of the headlap projections laterally across the shingle. 9. The roofing shingle according to claim 1, wherein the shingle is single-layer. 10. A roofing system comprising a plurality of the roofing shingle according to claim 1, wherein the roofing system comprises a plurality of courses of said shingles, and wherein the lateral trailing edge of a subsequently installed at least one of said shingles in a first course of shingles overlaps the lateral leading edge of an adjacent one of said previously installed shingles in the first course to provide a side-lap region, and wherein the side-lap region forms a part of a partially side-lapped recessed horizontal buttlap portion having a breadth about equal to the primary horizontal breadth;and wherein at least one of said shingles in a subsequent course of shingles provides:(a) a generally uniform overlap region over the headlap portions of a first adjacent shingle and a second adjacent shingle in the first course; and(b) an expanded overlap region over the headlap portion of the second adjacent shingle, wherein the expanded overlap region is due to the increased projection breadth of the first headlap projection nearest to the lateral leading edge of the second adjacent shingle. 11. The roofing system according to claim 10, wherein a buttlap projection nearest to the trailing edge of said at least one of said shingles in the subsequent course of shingles overlaps the side-lap region between adjacent shingles in the first course. 12. The roofing system according to claim 10, wherein the buttlap portion is further surfaced with a third further contrasting shade of granules on the buttlap projections. 13. The roofing system according to claim 10, wherein at least one of said buttlap projections has a shape that mirrors one of the headlap projections laterally across said at least one of said shingles. 14. The roofing system according to claim 10, wherein the side-lap region has a breadth of about 3 inches. 15. A roofing system comprising: single-layer shingles in more than one course wherein each of said shingles has a length, a headlap portion, a buttlap portion, a lateral leading edge, and a lateral trailing edge;wherein said buttlap portion includes a plurality of buttlap projections extending away from the shingle defining a maximum buttlap width;wherein the buttlap projections have a breadth that is about equal for each buttlap projection defining a primary projection breadth opposite a primary horizontal breadth at a horizontal edge;wherein said headlap portion includes a plurality of headlap projections extending away from the shingle defining a maximum headlap width;wherein a first of said headlap projections nearest to the lateral leading edge has an increased projection breadth that is greater than the primary projection breadth, and the increased projection breadth of the first of said headlap projections nearest to the lateral leading edge is greater than a breadth of at least another of said headlap projections: and wherein said breadth of said at least another of said headlap projections is about equal to the primary projection breadth;wherein the maximum headlap width is less than the maximum buttlap width;wherein the roofing system comprises a plurality of courses of said shingles, and wherein the lateral trailing edge of a subsequently installed at least one of said shingles in a first course of shingles overlaps the lateral leading edge of an adjacent previously installed one of said shingles in the first course to provide a side-lap region;and wherein at least one of said shingles in a subsequent course of shingles provides:(a) a generally uniform overlap region over the headlap portions of a first adjacent shingle and a second adjacent shingle in the first course, wherein the generally uniform overlap region has a transverse dimension that varies by less than 10% across the length of shingle in the subsequent course; and(b) an expanded overlap region over the headlap portion of the second adjacent shingle, wherein the expanded overlap region is due to the increased projection breadth of the first headlap projection nearest to the lateral leading edge of the second adjacent shingle. 16. The roofing system according to claim 15, wherein the buttlap projections and the headlap projections have a trapezoidal shape. 17. The roofing system according to claim 16, wherein the buttlap projections have a minimum breadth that extends away from the shingle, and wherein the headlap projections have a minimum breadth that extends away from the shingle. 18.
