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.

Claims

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.

2. The shingle of claim 1, wherein the shingle is comprised a single layer of shingle material with the front and rear surfaces being on opposite sides of the single layer of shingle material.

3. The shingle of claim 1, wherein the shingle is comprised of at least two layers of shingle material laminated together, with the front and rear surfaces being on opposite sides of the shingle.

4. The shingle of claim 1, wherein the reinforcement second thickness layer extends at least partially lower than the fastening zone, toward the lower edge of the shingle.

5. The shingle of claim 1, wherein the reinforcement second thickness layer extends at least partially into the fastening zone toward the upper edge of the shingle.

6. The shingle of claim 3, wherein the reinforcement second thickness layer extends at least partially lower than the fastening zone, toward the lower edge of the shingle.

7. The shingle of claim 3, wherein the reinforcement second thickness layer extends at least partially into the fastening zone toward the upper edge of the shingle.

16. A roof with a shingle according to claim 1 fastened thereto.

17. A roof with a shingle according to claim 2 fastened thereto.

18. A roof with a shingle according to claim 3 fastened thereto.

19. A roof with a shingle according to claim 4 fastened thereto.

20. A roof with a shingle according to claim 5 fastened thereto.

21. A roof with a shingle according to claim 6 fastened thereto.

22. A roof with a shingle according to claim 7 fastened thereto.

8. A method of making 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, comprising the steps of:

(a) providing a base layer of mat having front and rear surfaces;

(b) providing a coating of asphaltic material on both said front and rear surfaces of the mat;

(c) providing coatings of granular material on the asphaltic material on said both front and rear surfaces, so that the structures of clauses (a), (b) and (c) comprise a first thickness layer;

(d) providing a longitudinal fastening zone between right and left shingle edges, generally intermediate said upper and lower shingle edges;

(e) providing an at least partially externally visible generally longitudinal reinforcement second thickness layer of a substantially thinner dimension than said first thickness layer; and

adhering the reinforcement second thickness layer to an exterior surface of the shingle, extending at least substantially between right and left edges of the shingle; and

(f) making the reinforcement second thickness layer extend at least partially lower than the fastening zone or at least partially into the fastening zone.

9. The method of claim 8, wherein the shingle is comprised of a single layer of shingle material, with the front and rear surfaces being on opposite sides of the single layer of shingle material.

10. The method of claim 8, wherein the shingle is comprised of at least two layers of shingle material, including the step of laminating the at least two layers of shingle material together, with the front and rear surfaces of the shingle being on opposite sides of the shingle.

11. The method of claim 8, including the step of extending the reinforcement second thickness layer at least partially lower than the fastening zone, toward the lower edge of the shingle.

12. The method of claim 8, including the step of extending the reinforcement second thickness layer at least partially into the fastening zone toward the upper edge of the shingle.

13. The method of claim 10, including the step of extending the reinforcement second thickness layer at least partially lower than the fastening zone, toward the lower edge of the shingle.

14. The method of claim 10, including the step of extending the reinforcement second thickness layer at least partially into the fastening zone toward the upper edge of the shingle.

15. The method of claim 8, whereby fasteners applied through the fastening zone will pass through the reinforcement second thickness layer.
