Abstract

A shingle, a method of making it, and a roof embodying the shingle is provided, in which an exterior surface of the shingle is provided with an attached reinforcement layer through which fasteners may be applied when the shingle is applied to a roof.

First claim

What is claimed is:

1 . A shingle having front and rear exterior surfaces and being comprised of shingle material, with the shingle having a width defined by upper and lower edges and a length defined by right and left edges, the shingle comprising:
(a) a base layer of mat having front and rear surfaces; (b) a coating of asphaltic material on both front and rear surfaces of the mat; (c) coatings of granular material on said both front and rear surfaces of the mat, which, together with said base layer of mat and said coating of asphaltic material comprise a first thickness layer; (d) a longitudinal fastening zone between right and left shingle edges, generally intermediate said upper and lower edges; (e) and an at least partially externally visible generally longitudinal reinforcement second thickness layer of a substantially thinner dimension than said first thickness layer; said reinforcement second thickness layer being adhered to an exterior surface of said shingle and extending at least substantially between right and left edges of the shingle; and (f) said reinforcement second thickness layer extending at least partially lower than the fastening zone, toward the lower edge of the shingle or at least partially into the fastening zone toward the upper edge of the shingle, said reinforcement second thickness layer providing increased nail pull resistance.

2 . A roof with a plurality of shingles according to claim 1 fastened thereto.

3 . The shingle of claim 1 , the reinforcement second thickness layer being selected from the group consisting of polyester mats and fiberglass scrims.

4 . The shingle of claim 1 wherein the increased nail pull resistance is statistically significant at at least the 90 percent confidence level.

5 . The shingle of claim 1 wherein the reinforcement second thickness layer provides at least a 12 percent increase in nail pull resistance.

6 . The shingle of claim 5 wherein the reinforcement second thickness layer provides at least a 24 percent increase in nail pull resistance.

7 . A shingle having front and rear exterior surfaces and being comprised of shingle material, with the shingle having a width defined by upper and lower edges and a length defined by right and left edges, the shingle comprising:
(a) a base layer of mat having front and rear surfaces; (b) a coating of asphaltic material on both front and rear surfaces of the mat; (c) coatings of granular material on said both front and rear surfaces of the mat, which, together with said base layer of mat and said coating of asphaltic material comprise a first thickness layer; (d) a longitudinal fastening zone between right and left shingle edges, generally intermediate said upper and lower edges; (e) and an at least partially externally visible generally longitudinal reinforcement second thickness layer of a substantially thinner dimension than said first thickness layer; said reinforcement second thickness layer being provided on an exterior surface of said shingle and extending at least substantially between right and left edges of the shingle; and (f) said reinforcement second thickness layer extending at least partially lower than the fastening zone, toward the lower edge of the shingle or at least partially into the fastening zone toward the upper edge of the shingle.

8 . A roof with a plurality of shingles according to claim 7 fastened thereto.

9 . The shingle of claim 7 , wherein the reinforcement second thickness layer is provided on the rear exterior surface of the shingle.

10 . A pair of laminated shingles applied to a roof in two adjacent courses, each laminated shingle having a top sheet applied over a backing sheet, each backing sheet having a lower marginal edge, each top sheet having a headlap marginal edge, wherein the second course of shingles is applied over the first course of shingles such that the lower marginal edge of the backing sheet of the second course of shingles is coextensive with the headlap marginal edge of the top sheet of the first course of shingles;
each shingle having front and rear exterior surfaces and being comprised of shingle material, with the shingle having a width defined by upper and lower edges and a length defined by right and left edges, each shingle comprising: (a) a base layer of mat having front and rear surfaces; (b) a coating of asphaltic material on both front and rear surfaces of the mat; (c) coatings of granular material on said both front and rear surfaces of the mat, which, together with said base layer of mat and said coating of asphaltic material comprise a first thickness layer; (d) a longitudinal fastening zone between right and left shingle edges, generally intermediate said upper and lower edges; and (e) an at least partially externally visible generally longitudinal reinforcement second thickness layer of a substantially thinner dimension than said first thickness layer; said reinforcement second thickness layer being adhered to an exterior surface of said shingle, being at least partially within said fastening zone and being at least substantially between right and left edges of the shingle.

11 . A pair of shingles according to claim 10 , with said reinforcement second thickness layer extending lower than the fastening zone, toward the lower edge of the shingle.

12 . A pair of shingles according to claim 10 , wherein the reinforcement second thickness layer is on the rear exterior surface of the shingle.

13 . A pair of shingles according to claim 11 , wherein the reinforcement second thickness layer is on the rear exterior surface of the shingle.
