A method for bundling roofing shingles comprising:
- forming a plurality of discrete roofing shingles so that at least three patterns of shingles are formed,
- separating and stacking shingles into multiple bundles of sorted shingles, wherein each bundle of a multiplicity of bundles has a different repeating sequence of the at least three patterns of shingles;
- separating a first set of formed shingles from a second set of formed shingles;
- and
- positioning a first diverter downstream from the first set of shingles, and positioning a second diverter downstream from the second set of shingles, wherein the first diverter receives and separates shingles in the first set alternatingly into a first catcher and a second catcher;
- and wherein the second diverter receives and separates shingles in the second set alternatingly into a third catcher and a fourth catcher.
