Shingle with reinforcement member
A roofing shingle includes an asphalt-coated sheet and a reinforcement member. The asphalt-coated sheet includes a shingle mat and an asphalt coating applied to the shingle mat. The asphalt-coated sheet has a lower tab portion normally exposed on a roof and an upper headlap portion normally covered-up on a roof. At least a portion of the asphalt-coated sheet is coated with granules. The reinforcement member is adhered to the asphalt-coated sheet along an upper edge of the headlap portion, with the reinforcement member and the headlap portion together providing a nail pull-through value that is greater than an otherwise identical shingle having no such reinforcement material.
1. A roofing shingle comprising:
an asphalt-coated sheet including a shingle mat and an asphalt coating applied to the shingle mat, the asphalt-coated sheet having a lower tab portion normally exposed on a roof and an upper headlap portion normally covered-up on a roof, wherein at least a portion of the asphalt-coated sheet is coated with granules; and
a reinforcement member adhered to the asphalt-coated sheet along an upper edge of the headlap portion, with the reinforcement member and the headlap portion together providing a nail pull-through value that is greater than an otherwise identical shingle having no such reinforcement material;
wherein the reinforcement member causes a depression in the headlap portion of the asphalt-coated sheet, thereby reducing the thickness of the shingle at the reinforcement member.
2. The roofing shingle of claim 1 , wherein the reinforcement member is adhered to a front surface of the headlap portion.
3. The roofing shingle of claim 1 wherein the reinforcement member is adhered to a rear surface of the headlap portion.
4. The roofing shingle of claim 1 , wherein the reinforcement member has substantially no granules adhered thereto.
5. The roofing shingle of claim 1 , wherein the asphalt-coated sheet is an overlay sheet, the roofing shingle further comprising an underlay sheet secured to a rear surface of the overlay sheet.
6. The roofing shingle of claim 5 , wherein the reinforcement member is entirely disposed on a single layer portion of the roofing shingle, spaced apart from the underlay sheet.
7. The roofing shingle of claim 1 , wherein the reinforcement member and the headlap portion together provide a nail pull-through value that is between about 10 percent greater and about 100 percent greater than an otherwise identical shingle having no such reinforcement material.
8. The roofing shingle of claim 1 , wherein the reinforcement member is adhered directly to the asphalt coating of the asphalt-coated sheet.
9. The roofing shingle of claim 1 , wherein the reinforcement member comprises a first reinforcement member, the roofing shingle further comprising a second reinforcement member adhered to the asphalt coated sheet at a location spaced apart from the first reinforcement member.
10. The roofing shingle of claim 9 , wherein the second reinforcement member is adhered to the asphalt-coated sheet along a lower edge of the headlap portion.
11. The roofing shingle of claim 1 , wherein the reinforcement member is formed from a woven material.
12. The roofing shingle of claim 1 , wherein the reinforcement member is formed from a polymeric material.
13. The roofing shingle of claim 1 , wherein the roofing shingle comprises a single layer shingle.
14. The roofing shingle of claim 1 , wherein the reinforcement member extends longitudinally from a first end of the asphalt-coated sheet to a second end of the asphalt-coated sheet.
15. The roofing shingle of claim 1 , wherein the reinforcement member has a thickness of at least 3.0 mils.
16. The roofing shingle of claim 1 , wherein the reinforcement member is attached to the granule coated portion of the asphalt-coated sheet.
17. The roofing shingle of claim 1 , wherein the thickness of the reinforcement member is up to about 5.0 mils.
18. A roofing shingle comprising:
an asphalt-coated sheet including a shingle mat and an asphalt coating applied to the shingle mat, the asphalt-coated sheet having a lower tab portion normally exposed on a roof and an upper headlap portion normally covered-up on a roof, wherein at least a portion of the asphalt-coated sheet is coated with granules; and
a reinforcement member having a thickness smaller than a thickness of the asphalt coated sheet and being adhered to and covering an exterior surface of the asphalt-coated sheet along an upper edge of the headlap portion, with the reinforcement member and the headlap portion together providing a nail pull-through value that is greater than an otherwise identical shingle having no such reinforcement material;
wherein the reinforcement member comprises a first reinforcement member, the roofing shingle further comprising a second reinforcement member adhered to the asphalt coated sheet at a location spaced apart from the first reinforcement member, and wherein the second reinforcement member defines a nail zone.
19. A roofing shingle comprising:
an asphalt-coated sheet including a shingle mat and an asphalt coating applied to the shingle mat, the asphalt-coated sheet having a lower tab portion normally exposed on a roof and an upper headlap portion normally covered-up on a roof, wherein at least a portion of the asphalt-coated sheet is coated with granules; and
a reinforcement member having a thickness smaller than a thickness of the asphalt coated sheet and being adhered to a rear surface of the asphalt-coated sheet along an upper edge of the headlap portion, with the reinforcement member and the headlap portion together providing a nail pull-through value that is greater than an otherwise identical shingle having no such reinforcement material;
wherein the reinforcement member is attached directly to the shingle mat, and covered by the asphalt coating.
20. The roofing shingle of claim 19 , wherein the thickness of the reinforcement member is up to about 5.0 mils.
