FLEXIBLE LAMINATED HIP AND RIDGE SHINGLE
A laminated asphalt shingle including a base layer, a first decorative layer, and a second decorative layer is provided. The first decorative layer may be affixed to the base layer and to the second decorative layer by a flexible adhesive that permits the first decorative layer to move relative to both the base layer and the second decorative layer without de-bonding. The relative movement of the shingle layers permits the shingle to be folded over the ridge line of a roof without de-bonding or breaking the layers. Additionally, the relative movement of the layers when the shingle is installed over a ridge creates opposing transverse edges in which each layer is offset from the other layers as a result of the shingle bending about a different radius of curvature, thereby providing a dimensional appearance along the transverse edges.
1 . A shingle for use as a hip and ridge shingle:
a base layer having a first length dimension and a first width dimension; and
a first decorative layer having a second length dimension and a second width dimension,
wherein at least one of said second length dimension and said second width dimension is the same as or smaller than said first length dimension and said first width dimension, and
wherein said first decorative layer is affixed to said base layer by a flexible adhesive that allows a movement of said first decorative layer relative to said base layer without cracking or breaking said first decorative layer.
2 . The shingle of claim 1 , further comprising:
a second decorative layer affixed to said first decorative layer by said flexible adhesive, said flexible adhesive permitting said second decorative layer to move relative to said first decorative layer without cracking or breaking said first or second decorative layer.
3 . The shingle of claim 1 , wherein at least one of said second length and width dimensions is the same as or smaller than the corresponding first length and width dimension.
4 . The shingle of claim 1 , wherein said flexible adhesive comprises:
a hydrocarbonaceous material;
a linear copolymer having an A-B di-block or an A-B-A tri-block structure; and
an oil.
5 . The shingle of claim 4 , wherein said oil is selected from petroleum-based oils, naphthenic oils, paraffinic oils and combinations thereof.
6 . The shingle of claim 4 , further comprising a member selected from one or more fillers, a radial copolymer and combinations thereof, said radial copolymer being selected from a block copolymer having an (A-B) n radial structure where n is an integer of at least 4 and a block copolymer having a tri-block (A-B-A) radial structure having from 4-8 arms.
7 . The shingle of claim 6 , wherein said radial copolymer is selected from styrene-butadiene-styrene (SBS) radial copolymers and styrene-isoprene radial copolymers, and
wherein the copolymer forming said linear copolymer is selected from styrene-butadiene block copolymers and styrene-isoprene block copolymers.
8 . The shingle of claim 4 , wherein said adhesive provides flexibility at temperatures as less than or equal to about 40° F.
9 . A hip and ridge shingle for covering a ridge line or hip of a roof comprising:
a base layer having a first length dimension and a first width dimension; and
a first decorative layer having a second length dimension and a second width dimension, at least one of said second length and width dimensions being smaller than the corresponding first length and width dimensions,
wherein said first decorative layer is affixed to said base layer by a flexible adhesive that allows a limited movement of said first decorative layer relative to said base layer to permits said first decorative layer to bend about a different radius of curvature than said base member when said hip and ridge is bent over said ridge line or said hip.
10 . The hip and ridge shingle of claim 9 , further comprising:
a second decorative member affixed to said first decorative member by said flexible adhesive to allow a limited movement of said second decorative layer relative to said first decorative layer, thus allowing said second decorative layer to bend at a different radius of curvature than said first decorative layer.
11 . The hip and ridge shingle of claim 9 , wherein each of said base layer, said first decorative layer, and said second decorative layer have opposing transverse edges, the corresponding said transverse edges of said first decorative layer being offset relative to said base layer and relative to said second decorative layer when said hip and ridge shingle is installed on said ridge line or said hip.
12 . The hip and ridge shingle of claim 9 , wherein said adhesive provides flexibility at temperatures less than or equal to about 40° F.
13 . The hip and ridge shingle of claim 12 , wherein said flexible adhesive comprises:
a hydrocarbonaceous material;
a linear copolymer having an A-B di-block or an A-B-A tri-block structure; and
an oil.
14 . The hip and ridge shingle of claim 13 , wherein said oil is selected from petroleum-based oils, naphthenic oils, paraffinic oils and combinations thereof.
15 . The hip and ridge shingle of claim 13 , further comprising a member selected from one or more fillers, a radial copolymer and combinations thereof, said radial copolymer being selected from a block copolymer having an (A-B) n radial structure where n is an integer of at least 4 and a block copolymer having a tri-block (A-B-A) radial structure having from 4-8 arms.
16 . A hip and ridge shingle for mounting on a roof to cover a ridge line or hip of said roof, comprising:
a base layer having a first length dimension and a first width dimension;
a first decorative layer having a second length dimension and a second width dimension;
a second decorative layer affixed to said first decorative layer to provide areas of greater thickness on said base member; and
a flexible adhesive securing said first decorative layer to said base layer and said first decorative layer to said second decorative layer such that said first layer is operable to move relative to both said base layer and said second decorative layer to permit each of said base layer, said first decorative layer and said second decorative layer to bend with a different radius of curvature when said hip and ridge shingle is applied to said roof over said ridge line or said hip.
17 . The hip and ridge shingle of claim 16 , wherein said flexible adhesive permits said first and second decorative layers to move relative to each other and said base layer said without cracking or breaking said first or second decorative layer.
18 . The hip and ridge shingle of claim 16 , wherein at least one of said second length and width dimensions is smaller than the corresponding first length and width dimensions, said first decorative layer being affixed to said base layer.
19 . The hip and ridge shingle of claim 18 , wherein each of said base layer, said first decorative layer, and said second decorative layer have opposing transverse edges, the corresponding said transverse edges of said first decorative layer being offset relative to said base layer and relative to said second decorative layer when said hip and ridge shingle is installed on said ridge line or said hip.
20 . The hip and ridge shingle of claim 16 , wherein said flexible adhesive comprises:
a hydrocarbonaceous material;
a linear copolymer having an A-B di-block or an A-B-A tri-block structure; and
an oil.
21 . The hip and ridge shingle of claim 14 , wherein said oil is selected from petroleum-based oils, naphthenic oils, paraffinic oils and combinations thereof.
22 . The hip and ridge shingle of claim 15 , further comprising a member selected from one or more fillers, a radial copolymer and combinations thereof, said radial copolymer being selected from a block copolymer having an (A-B) n radial structure where n is an integer of at least 4 and a block copolymer having a tri-block (A-B-A) radial structure having from 4-8 arms.
