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.

First claim

1 . 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.

2 . The hip and ridge shingle according to claim 1 , wherein the overlay sheet is attached to the underlay sheet by an adhesive.

3 . The hip and ridge shingle according to claim 1 , wherein the first asphalt coating composition comprises polymer modified asphalt coating.

4 . The hip and ridge shingle according to claim 3 , wherein the polymer modified asphalt coating comprises: asphalt; a polymer additive; and a secondary additive.

5 . The hip and ridge shingle according to claim 4 , wherein the secondary additive comprises one or more of a wax, a salt of a fatty acid ester, and an amide of a fatty acid.

6 . The hip and ridge shingle according to claim 3 , wherein the polymer modified asphalt coating comprises 85-99 wt. % asphalt, 1-13 wt. % polymer additive, and 1-6 wt. % wax.

7 . The hip and ridge shingle according to claim 3 , wherein the polymer modified asphalt coating further comprises a filler.

8 . The hip and ridge shingle according to claim 1 , wherein the reinforced nail zone comprises a strip of nail zone reinforcement material.

9 . The hip and ridge shingle according to claim 8 , wherein the strip of nail zone reinforcement material comprises a woven polyester fabric.

10 . The hip and ridge shingle according to claim 1 , wherein the sealant is positioned in a location on the foldable portion adapted to contact a reinforced nail zone of an adjacent hip and ridge shingle upon installation on a roof.

11 . 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.

12 . The hip and ridge roofing material according to claim 11 , wherein the overlay layer is attached to the underlay layer by an adhesive.

13 . The hip and ridge roofing material according to claim 11 , wherein the polymer modified asphalt coating comprises: asphalt; a polymer additive; and a secondary additive.

14 . The hip and ridge roofing material according to claim 13 , wherein the secondary additive comprises one or more of a wax, a salt of a fatty acid ester, and an amide of a fatty acid.

15 . The hip and ridge roofing material according to claim 11 , wherein the polymer modified asphalt coating comprises 85-99 wt. % asphalt, 1-13 wt. % polymer additive, and 1-6 wt. % wax.

16 . The hip and ridge roofing material according to claim 11 , wherein the polymer modified asphalt coating further comprises a filler.

17 . The hip and ridge roofing material according to claim 11 , wherein the reinforced nail zone comprises a strip of nail zone reinforcement material.

18 . The hip and ridge roofing material according to claim 17 , wherein the strip of nail zone reinforcement material comprises a woven polyester fabric.

19 . The hip and ridge roofing material according to claim 11 , wherein the sealant is positioned in a location on the foldable portion adapted to contact a reinforced nail zone of an adjacent hip and ridge shingle upon installation on a roof.

20 . 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.
