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.
Claims28
A roofing shingle comprising:
- an overlay sheet including a headlap portion and a tab portion;
- 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;
- wherein the overlay sheet has a non-uniform thickness;
- and
- a reinforcement material secured to the headlap portion of the overlay sheet, wherein the reinforcement material is configured to improve nail pull-through, wherein the reinforcement material extends beyond the overlapping regions of the headlap portion and the underlay sheet;
- wherein the reinforcement material and the headlap portion provide a nail pull-through value that is at least 13.3 percent greater than an otherwise identical shingle having no such reinforcement material.
A roofing shingle comprising:
- an overlay sheet including a headlap portion and a tab portion, wherein the overlay sheet has an overlay sheet height;
- an underlay sheet secured to a bottom surface of the overlay sheet such that a region of the underlay sheet overlaps a region of the headlap portion of the overlay sheet, wherein the underlay sheet has a height equal to approximately half of the overlay sheet height;
- wherein the overlay sheet has a non-uniform thickness;
- and
- a reinforcement material secured to a top surface of the headlap portion of the overlay sheet, wherein the reinforcement material is configured to improve nail pull-through, wherein the reinforcement material extends beyond the overlapping regions of the headlap portion and the underlay sheet.
A roofing shingle comprising:
- an overlay sheet including a headlap portion and a tab portion;
- an underlay sheet secured to a bottom surface of the overlay sheet such that a region of the underlay sheet overlaps a region of the headlap portion of the overlay sheet;
- wherein the overlay sheet has a non-uniform thickness;
- and
- a reinforcement material secured to a top surface of the headlap portion, wherein the reinforcement material is configured to improve nail pull-through, wherein the reinforcement material has a height, wherein the overlapping regions of the underlay sheet and the headlap portion of the overlay sheet have a height, wherein the ratio of the height of the overlapping regions to the height of the reinforcement material is in a range of from about 70% to about 100%.
A roofing shingle comprising:
- an overlay sheet including a headlap portion and a tab portion, the tab portion including a plurality of cutouts, the plurality of cutouts having an upper edge;
- an underlay sheet secured to a bottom surface of the overlay sheet such that a region of the underlay sheet overlaps a region of the headlap portion of the overlay sheet;
- wherein the overlay sheet has a non-uniform thickness;
- and
- a reinforcement material secured to a top surface of the headlap portion, the reinforcement material is configured to improve nail pull-through, wherein the reinforcement material has a lower edge, wherein the distance from the upper edge of the plurality of the cutouts to the lower edge of the reinforcement material is about 0.25 inches or less;
- wherein the reinforcement material extends beyond the overlapping regions of the headlap portion and the underlay sheet.
