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.

First claim

What is claimed is:

1. 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 reinforcement material secured directly to the asphalt coating on the headlap portion of the overlay sheet without extending into the tab portion to provide a reinforced nail zone along a longitudinal axis of the shingle, with the 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;
wherein the reinforcement material extends beyond the overlapping regions of the headlap portion and the underlay, such that a first portion of the reinforcement material is disposed on a dual-layer portion of the shingle and a second portion of the reinforcement material is disposed on a single-layer portion of the shingle.

2. The roofing shingle of claim 1 , wherein the second portion of the reinforcement material is wider than the first portion of the reinforcement material.

3. The roofing shingle of claim 1 , wherein the first portion of the reinforcement material extends into the dual-layer portion of the shingle by a distance of no greater than ⅛ inch.

4. The roofing shingle of claim 1 , wherein at least about 70% of the reinforcement material is disposed on a dual-layer portion of the shingle.

5. The roofing shingle of claim 1 , wherein the reinforcement material comprises a woven material.

6. The roofing shingle of claim 1 , wherein the reinforcement material comprises a non-woven material.
