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.

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; anda 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; anda 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.
