SINGLE LAYER FOLDABLE REINFORCED BULLNOSE HIP AND RIDGE CAP SHINGLE

摘要

A single layer foldable reinforced bullnose hip and ridge cap shingle is cut from a single layer web of shingle material. The hip and ridge cap shingle includes an exposed portion, a tapered portion, and a portion in between that will be folded to form a bullnose edge. Two spaced apart perforated fold lines extend transversely across the shingle and two spaced apart transversely extending strips of reinforcing scrim material flank the perforated fold lines. To form a bullnose hip or ridge cap shingle, the shingle is folded first along one of the perforated fold lines and again along the other perforated fold line. This creates an exposed edge portion that is four layers thick and this extreme edge takes on a pleasant rounded bullnose appearance covered with granules. The reinforcing scrim is located at the edge and reinforces the bullnose edge to prevent cracking at the fold.

主权项

1. A hip or ridge cap shingle comprising:
a shingle blank having an elongated body with a bottom side, a top side, a front portion, a back portion, and an intermediate portion between the front portion and the back portion; a first fold line extending transversely across the shingle blank allowing the front portion to be folded along the first fold line at least partially beneath the back portion forming a two-layer forward edge portion; a second fold line extending transversely across the shingle blank allowing the two layer forward edge portion to be folded at least partially beneath the intermediate portion forming a four-layer forward edge portion with a bullnose edge; a ribbon of reinforcing material having a width and extending transversely across the elongated body of the shingle blank; the ribbon of reinforcing material being positioned on the shingle to extend around the bullnose edge of the four-layer forward edge portion to provide support and crack resistance along the bullnose edge.
