A roofing system and roofing shingles for use therein are disclosed. The roofing system comprises a multiplicity of courses of roofing shingles having a headlap portion, a buttlap portion, a lateral leading edge, and a lateral trailing edge, wherein the headlap portion has a width that is less than a width of the buttlap portion defining a reduced-width headlap, wherein the lateral trailing edge of a shingle in a course partially overlaps and partially abuts the lateral leading edge of an adjacent previously installed shingle to form an interlocking edge between adjacent shingles in the course, and wherein the lateral edge includes a trailing edge projection having a weather edge, a rear edge, and a variable breadth that increases toward the rear edge of the trailing edge projection.

1. A roofing system comprising: single-layer shingles having a headlap portion, a buttlap portion, a lateral leading edge, and a lateral trailing edge;wherein said headlap portion has a maximum headlap width that is less than a maximum buttlap width of said buttlap portion;wherein said lateral leading edge includes at least one leading abutting portion and a leading edge projection that extends away from the shingle;wherein said lateral trailing edge includes at least one trailing abutting portion and a trailing edge projection that extends away from the shingle;wherein the roofing system comprises a plurality of courses of the shingles, and wherein the lateral trailing edge of a subsequently installed shingle in a first course of shingles partially abuts and partially overlaps the lateral leading edge of an adjacent previously installed shingle in the first course of shingles to form an interlocking edge between adjacent shingles in the first course of shingles;and wherein the trailing edge projection has a weather edge, a rear edge, and a variable breadth that increases toward the rear edge of the trailing edge projection. 2. The roofing system according to claim 1, wherein the at least one leading abutting portion includes a first leading portion and a second leading portion that are separated by the leading edge projection; wherein the at least one trailing abutting portion includes a first trailing portion and a second trailing portion that are separated by the trailing edge projection;and wherein the interlocking edge comprises a first abutment region defined by an abutment of the first leading portion and the first trailing portion of the adjacent shingles in the first course of shingles, a side-lap region defined by an overlap of the trailing edge projection and an underlap of the leading edge projection between the adjacent shingles in the first course of shingles, and a second abutment region defined by an abutment of the second leading portion and the second trailing portion in the first course of shingle. 3. The roofing system according to claim 2, wherein the first abutment region and the second abutment region each have a height of about 2 inches. 4. The roofing system according to claim 2, wherein the first abutment region has a height of about 1 inch and the second abutment region has a height of about 1½ inches. 5. The roofing system according to claim 2, wherein the side-lap region has a maximum breadth that is about 6 inches. 6. The roofing system according to claim 1, wherein the trailing edge projection has a continuously curved profile. 7. The roofing system according to claim 1, wherein the trailing edge projection has a straight lateral portion. 8. The roofing system according to claim 7, where the straight lateral portion has a constant breadth. 9. The roofing system according to claim 8, wherein the variable breadth of the trailing edge projection includes a maximum breadth that is about equal to the constant breadth of the straight lateral portion. 10. The roofing system according to claim 1, wherein the variable breadth of the trailing edge projection includes a maximum breadth that is about 3 inches. 11. The roofing system according to claim 1, wherein the leading edge projection has a maximum breadth that is about equal to the maximum breadth of the trailing edge projection. 12. The roofing system according to claim 1, wherein the trailing edge projection has a height that spans at least a portion of the headlap portion and at least a portion of the buttlap portion. 13. The roofing system according to claim 1, wherein the leading edge projection has a height that is about equal to the height of the trailing edge projection. 14. The roofing system according to claim 1, wherein the leading edge projection has a shape that mirrors the trailing edge projection. 15. The roofing system according to claim 1, wherein the shingles further comprise an alignment means. 16. The roofing system according to claim 15, wherein the alignment means includes sealant strips, a convergence point between the trailing edge projection and the first trailing portion, and a front edge of the leading edge projection. 17. The roofing system according to claim 1, wherein the shingles have a non-straight longitudinal front edge. 18. The roofing system according to claim 17, wherein the non-straight longitudinal front edge includes a central horizontal portion, a left horizontal portion, a right horizontal portion, a first transition portion, and a second transition portion, wherein the central horizontal portion extends further away from the shingle than the left horizontal portion and the right horizontal portion, and wherein the first transition portion is situated between the left horizontal portion and the central horizontal portion and the second transition portion is situated between the central horizontal portion and the right horizontal portion. 19. The roofing system according to claim 1, wherein the shingles are cut from a sheet of roofing material and wherein the shingles provide a coverage area such that the shingles required to cover 100 ft2 of a roof deck are made from less than 200 ft2 of the sheet of roofing material. 20. The roofing system according to claim 19, wherein the shingles required to cover 100 ft2 of the roof deck are made from less than 180 ft2 of the sheet of roofing material. 21. The roofing system according to claim 20, wherein the shingles required to cover 100 ft2 of the roof deck are made from less than 168 ft2 of the sheet of roofing material. 22. A roofing shingle comprising: a headlap portion, a buttlap portion, a lateral leading edge, and a lateral trailing edge;wherein said shingle is a single-layer shingle;wherein said headlap portion has a maximum headlap width that is less than a maximum buttlap width of said buttlap portion;wherein said lateral leading edge includes at least one leading abutting portion and a leading edge projection that extends away from the shingle;wherein said lateral trailing edge includes at least one trailing abutting portion and a trailing edge projection that extends away from the shingle;and wherein the trailing edge projection has a weather edge, a rear edge, and a variable breadth that increases toward the rear edge of the trailing edge projection. 23. The roofing shingle according to claim 22, wherein the at least one leading abutting portion includes a first leading portion and a second leading portion that are separated by the leading edge projection; and wherein the at least one trailing abutting portion includes a first trailing portion and a second trailing portion that are separated by the trailing edge projection. 24. The roofing shingle according to claim 22, wherein the trailing edge projection has a continuously curved profile. 25.
