Abstract
A system for manufacturing a granule covered roofing shingle includes establishing at least two sources of granules. A standardized process for manufacturing granules having a standardized appearance is then established, wherein a color of the granules from one of the sources of granules is substantially identical to the color of the granules from the others of the sources of granules, thereby defining at least one standardized granule color. Granules of the standardized granule color are then manufactured according to the standardized process. The manufactured granules are transported to at least one shingle manufacturing facility, and granule covered roofing shingles are then manufactured using the manufactured granules of the standardized granule color.

A method for manufacturing a granule covered roofing shingle comprising:
- establishing at least two sources of granules;
- manufacturing coated granules from the at least two sources of granules;
- establishing a standardized process for manufacturing granules having a standardized appearance, the standardized process including the steps of selecting a uniform color scale value and selecting coated granules that have a color substantially identical to the uniform color scale value, wherein the coated granules are selected from one or more of the sources of granules;
- transporting the coated granules to more than one shingle manufacturing facility;
- manufacturing a first granule covered roofing shingle using the coated granules at a first facility;
- manufacturing a second granule covered roofing shingle using the coated granules at a second facility;
- sensing the color of the first and second roofing shingle;
- and
- determining whether the colors of the first roofing shingle and the second roofing shingle are within an acceptable limit of about 2.8 L*a*b* color units of each other.
