Abstract:
A laminated composition shingle includes a first sheet having a first mineral granule surface and a first rectangular shape without tab cut-outs laminated with a second sheet having a second mineral granule surface. The second sheet has tab cut-outs along only one longer edge of the second sheet. The laminated composition shingle has a shingle width perpendicular to the long edges, The tab cut-outs have a tab width in the direction of the shingle width where two times the tab width is less than the shingle width minus two and one quarter inches (57 mm). Two times the tab width may be more than the shingle width minus four inches (102 mm). If the shingle width is at least 12″ (305 mm), the tab cut-outs may have a tab width that is between 33% and 41.5% of the shingle width. All the tab cut-outs may have the same width.
