Abstract
Shingle blanks are provided. The shingle blanks include an underlay portion having a substrate coated with an asphalt coating and granules, the underlay portion having an upper edge and a lower edge. An overlay portion is adhered to the underlay portion, the overlay portion having a plurality of continuous layered segments, the layered segments having a sealant bead therebetween. A plurality of perforation lines extend in a substantially perpendicular direction from the upper edge to the lower edge of the underlay portion. The plurality of perforation lines are sufficient to facilitate separation of the shingle blank to form hip and ridge roofing shingles configured for application across a ridge or hip.

A shingle blank comprising:
- an underlay portion having a substrate coated with an asphalt coating and granules, the underlay portion having an upper edge and a lower edge;
- an overlay portion adhered to the underlay portion, the overlay portion having a plurality of continuous layered segments, the layered segments having a sealant bead therebetween;
- and
- a plurality of perforation lines extending in a substantially perpendicular direction from the upper edge of the overlay portion to the lower edge of the underlay portion;
- wherein the plurality of perforation lines are sufficient to facilitate separation of the shingle blank to form hip and ridge roofing shingles configured for application across a ridge or hip.
A method of manufacturing an asphalt-based shingle blank, comprising the steps of:
- forming a continuous sheet having a substrate coated with an asphalt coating and granules, the continuous sheet having a plurality of lanes configured to form an overlay portion and a plurality of lanes configured to form an underlay portion;
- separating the plurality of lanes configured to form an overlay portion from the plurality of lanes configured to form an underlay portion;
- folding the plurality of lanes configured to form an overlay portion thereby forming overlay an overlay portion, the overlay portion having continuous layered segments;
- adhering the overlay portion to the plurality of lanes configured to form an underlay portion thereby forming an applied sheet;
- forming a plurality of perforation lines in the applied sheet;
- and
- cutting the applied sheet into shingle blanks.
A method of installing a hip and ridge roofing shingle, comprising the steps of:
- providing an asphalt-based shingle blank having an overlay portion adhered to an underlay portion, the underlay portion having a substrate coated with an asphalt coating and granules, the underlay portion having an upper edge and a lower edge, the overlay portion having a plurality of continuous layered segments, the layered segments having a sealant bead therebetween, wherein a plurality of perforation lines extend in a substantially perpendicular direction from the upper edge of the overlay portion to the lower edge of the underlay portion;
- separating the shingle blank along the plurality of perforation lines to form hip and ridge roofing shingles;
- and
- installing the hip and ridge shingles across a hip or ridge.
