Abstract
A roofing shingle is provided. The roofing shingles includes an overlay sheet including a headlap portion and a tab portion and an underlay sheet secured to the overlay sheet such that a region of the underlay sheet overlaps a region of the headlap portion of the overlay sheet. A reinforcement material is secured to the headlap portion of the overlay sheet. The reinforcement material is configured to improve nail pull-through. The reinforcement material extends beyond the overlapping regions of the headlap portion and the underlay sheet a distance of about 0.12 inches or less.
Claims31
A roofing shingle comprising:
- an overlay sheet including a mat and an asphalt coating applied to the mat, and defining a headlap portion and a tab portion;
- an underlay sheet including a mat and an asphalt coating applied to the mat, the underlay sheet being secured to the overlay sheet such that a region of the underlay sheet overlaps a region of the headlap portion of the overlay sheet;
- and
- a woven reinforcement material secured directly to the asphalt coating on a rear surface of the headlap portion of the overlay sheet without extending into the tab portion, wherein the woven reinforcement material is configured to improve nail pull-through, wherein the woven reinforcement material extends beyond the overlapping regions of the headlap portion and the underlay;
- wherein the woven reinforcement material and the headlap portion provide a nail pull-through value that is greater than an otherwise identical shingle having no such reinforcement material;
- and
- wherein the shingle further includes a plurality of granules secured to the headlap portion of the overlay sheet and substantially not secured to the woven reinforcement material.
