Abstract
A cap shingle configured to be installed over a hip or ridge of a roof structure, and a method for creating scored hinge lines in hip and ridge cap shingles during manufacturing while minimizing the likelihood of breakage along the scored hinge lines due to lane tension are disclosed. The method includes forming score lines with a scoring cylinder across lanes of shingle material just before the lanes are cut into individual cap shingles with a pattern cutter. The scoring cylinder and pattern cutter are controlled so that the score lines are consistently applied along the centerlines of the cap shingles.
