ABSTRACT:
A method is provided for making a shingle by cutting a layer of shingle material to have a headlap area and a tab area, and with a plurality of tabs being present in the tab area, separated by slotted openings. The tab area of the shingle is made to have a predetermined design that has a repeatability in the longitudinal direction, or from one edge of a shingle to another in the right-to-left direction, which repeatability is a function of the length of the shingle between said left and right edges, as well as being a function of the number of tabs in the shingle, with the repeatability being greater or smaller than the length of the shingle in the longitudinal direction. Thereby, a method is provided for producing an ornamental appearance that has a random, natural-looking effect when the shingles are laid up on a roof.
