Abstract

An exemplary prefabricated offset shingle includes a headlap portion extending from a top edge to a nail zone, a tab portion extending from the nail zone to a bottom edge, the headlap portion and the tab portion extending between first and second side edges. Two transverse cuts extend from the bottom edge to the headlap portion, and frangible lines of weakness in line with the transverse cuts extend from the transverse cuts to the top edge. The cuts and lines of weakness separate the shingle into first, second, and third offset portions having first, second, and third widths.
