ABSTRACT:
This invention relates to a unitary roofing shingle sheet comprising (a) an undivided cop section having an unexposable upper portion and a lower portion carrying a partially exposable horizontal band of distinguishable colors or color patterns and (b) exposable tabs in a butt bottom section depending from the lower boundary of the band in the partially exposable portion of (a); the exposable portions of said shingle being covered with weather resistant granules of distinguishable hues or patterns disposed in discrete exposable areas in the band of section (a) and on each of said tabs so as to provide a distinctive color or pattern for each tab and a contrasting color or color pattern above each tab in the adjoining exposable portion of said band of section (a). In the shingle of the invention, the band of distinctive hues or patterns in the lower undivided portion of section (a) has a width approximately equal to the average height of the tabs in section (b); the tabs are spaced from each other by between about 0.5 and about 1.5 times the horizontal dimension of the tabs and the upper nonexposed portion of undivided section (a) has a width about equal to the width of said band plus y, wherein y has a value of from 1 to 5 inches.
