Abstract
A method of making a shingle and the shingle made in accordance with such method are provided, in which a shingle-forming layer of shingle material has a plurality of marks applied thereto prior to or after application of decorative granules to its tab region, and wherein the locations of the marks are sensed by a sensor, that then activates and controls the operation and placement of various shingle-completion steps as a function of the placement of the marks.
