Abstract
A roofing shingle is provided comprising a reduced-with headlap portion including headlap projections, a buttlap portion including buttlap projections, a lateral leading edge, and a lateral trailing edge, wherein the headlap projection nearest the lateral leading edge has an increased breadth. A roofing system is also provided comprising a multiplicity of courses of shingles of the invention, wherein a lateral trailing edge of a shingle in a single course overlaps (side-laps) an adjacent previously installed shingle, and wherein a shingle in a subsequent course provides a generally uniform overlap region over the headlap portions of a first and second adjacent shingle in the first course and an expanded overlap region over the second adjacent shingle, wherein the expanded overlap region is due to the increased breadth of the headlap projection nearest the lateral leading edge of the second adjacent shingle in the first course.
