A shingle blank includes a substrate coated with asphalt. A substantially V-shaped perforated cut line is formed in the substrate, and a substantially straight cut line extends from an apex the V-shaped perforated line toward a leading edge of the shingle blank. The V-shaped perforated cut line and the substantially straight cut line are structured and configured to facilitate separation of the shingle blank into discrete portions.
