A shingle blank includes a substrate coated with asphalt, a headlap portion, a prime portion, a starter shingle separation line, and first and second ridge shingle separation lines. The headlap portion has a first sealant that extends along the width of the substrate, and the prime portion has a second sealant that extends along the width of the substrate. The starter shingle separation line extends along the width of the substrate and facilitates separation of the shingle blank into first and second starter shingles. The first starter shingle includes the first sealant and the second starter shingle includes the second sealant. The first and second ridge shingle separation lines extend along the height of the substrate from an upper edge of the substrate to a lower edge of the substrate and facilitates separation of the shingle blank into three ridge shingles. Each of the three ridge shingles includes a portion of the first sealant and a portion of the second sealant.
