Abstract
A roofing system including a cap shingle and a method of producing a cap shingle are disclosed. In one embodiment, the cap shingle is formed with a continuous or discontinuous self-sealing adhesive that is applied along a ridgeline direction and can provide high wind resistance, without the use of hand-sealed adhesive application. In an embodiment of the method, one or more layers of a shingle material can be oriented in a machine direction with the self-sealing adhesive applied adjacent side edges of the shingle material to form the cap shingles having self-seal strips and configured to bend in the machine direction for installation of the cap shingles along a ridge of a roof.
Claims20
A cap shingle comprising:
- a first layer of shingle material defining an upper surface of the cap shingle and having first and second side edges, a front edge, a back edge, an exposure portion, and a headlap portion adjacent the back edge;
- a second layer of shingle material positioned beneath the first layer;
- the second layer defining a lower surface of the cap shingle;
- wherein the first and second layers of shingle material are configured to bend in an arc along in a ridgeline direction extending from the back edge to the front edge for installation along a ridge, hip, or rake of a roof;
- and
- one or more strips of adhesive along the lower surface of the cap shingle;
- wherein the one or more strips of adhesive are positioned adjacent the first and second side edges of the first layer of shingle material extend in the ridgeline direction of the cap shingle between the front edge and the back edge.
A method comprising:
- (a) moving a web of shingle material along a path in a machine direction;
- (b) applying an adhesive to a first surface of the web of shingle material to form strips of adhesive extending along the first surface of the web of shingle material, wherein the strips of adhesive are aligned in the machine direction;
- and
- (c) cutting the web of shingle material in synchronization with step (b) to form cap shingles having a front edge, a back edge, side edges and strips of adhesive positioned adjacent the side edges extending between the back edge and the front edge;
- wherein the cap shingles are configured to bend in the machine direction for installation of the cap shingles along a ridgeline of a ridge, hip or cap of a roof.
A roof comprising:
- a plurality of cap shingles arranged along a ridge, hip, or cap of the roof, each of the cap shingles comprising:
- at least one layer of shingle material including:
- an upper surface material including a headlap portion and an exposure portion;
- a lower surface;
- and
- a front edge, back edge and side edges;
- and
- strips of adhesive disposed along the lower surface of the at least one layer of shingle material;
- wherein the strips of adhesive are applied to the lower surface adjacent the side edges of the cap shingle, and extend along the side edges of the cap shingle in a ridgeline direction thereof;
- wherein the cap shingles are configured to bend along the ridgeline direction for installation of the cap shingles along the ridge, hip or cap of the roof, and are attached to the roof on opposite sides of the ridge, hip or cap.
