Abstract
An improved hip and ridge shingle is provided comprising a reinforced nail zone and a sealant applied to a bottom portion of the shingle and adapted to contact the reinforced nail zone of an adjacent shingle. Such a shingle structure surprisingly provides improved installation consistency and improved properties, such as reduced wind uplift and increased nail pull resistance.
Claims20
A hip and ridge roofing material comprising:
- an overlay sheet comprising a top overlay surface, a bottom overlay surface, a front portion, and a back portion, the overlay sheet comprising a first substrate coated with a first asphalt coating composition;
- an underlay sheet comprising a top underlay surface and a bottom underlay surface, the underlay sheet comprising a second substrate coated with a second asphalt coating composition, wherein the overlay sheet is attached to the underlay sheet such that a portion of the top underlay surface extends beyond the back portion of the overlay sheet, forming an uncovered portion;
- and wherein the front portion of the overlay sheet is folded under the underlay sheet such that a front edge contacts the bottom underlay surface, forming a folded portion;
- a release material located on the underlay sheet in the uncovered portion;
- a reinforced nail zone located in the back portion of the top overlay sheet, proximate to the release material;
- and
- a sealant located on a portion of the bottom surface of the folded portion.

A hip and ridge roofing material comprising:
- a laminated shingle having a foldable front portion, an opposing back portion, a top surface an opposing bottom surface, and a foldable centerline, wherein the laminated shingle includes:
- an overlay sheet comprising a first substrate coated with a polymer modified asphalt coating composition attached to an underlay sheet comprising a second substrate coated with an at least partially oxidized asphalt coating composition, wherein an upper surface of the overlay sheet defines the top surface and a lower surface of the underlay sheet defines the bottom surface, and wherein the foldable front portion of the laminated shingle is folded down below the underlay sheet such that a front edge of the foldable front portion contacts the bottom surface, forming a folded portion;
- a reinforced nail zone located on the top surface in the back portion, proximate to a back edge;
- and
- a sealant located on a bottom surface of the folded portion, wherein the laminated shingle is foldable along the centerline for application to a roof.
2 more elements
A method for producing a hip and ridge shingle comprising:
- laminating an overlay sheet comprising a top overlay surface, a bottom overlay surface, a front portion, and a back portion to an underlay sheet comprising a top underlay surface and a bottom underlay surface, forming a laminated shingle, wherein at least a portion of the overlay sheet is attached to the underlay sheet with an adhesive, such that a portion of a top surface of the underlay sheet extends beyond a back portion of the overlay sheet, forming an uncovered portion;
- folding a front portion of the overlay sheet under the underlay sheet such that a front edge of the overlay sheet contacts a bottom surface of the underlay sheet, forming a folded portion;
- applying a release material to the underlay sheet in the uncovered portion;
- applying a nail reinforcement material to the back portion of the overlay sheet, proximate to the release material;
- applying a sealant to a portion of the bottom surface of the folded portion;
- and
- folding the laminated shingle along a centerline for application to a hip or ridge of a roof.
