Abstract
Roofing shingles are disclosed that are capable of being attached to a roof deck, underlayment, and/or other roofing shingles and that require few mechanical fasteners to remain attached to the roof. The roofing shingles are formed with a first layer and a second layer of shingle materials that are laminated together, and with the first and second layers further being mechanically attached with indentations in the first and second layers at spaced locations along and across the roofing shingles. A roofing system comprising a plurality of courses of the roofing shingles is also disclosed.
Claims22
A roofing shingle, comprising:
- a first layer comprising:
- a headlap portion configured to be overlapped by at least one additional roofing shingle arranged in a next higher course of roofing shingles;
- and
- an exposure portion having a plurality of tabs;
- a second layer opposite the first layer;
- a plurality of indentations formed in the first and second layers of the roofing shingle;
- and
- raised areas along the plurality of tabs of the exposure portion formed from one or more of the plurality of indentations;
- wherein the plurality of indentations are configured to attach the first and second layers;
- wherein one or more of the plurality of indentations are formed in registration with one or more of the plurality of tabs of the exposure portion of the first layer;
- and
- wherein the plurality of indentations comprises a first plurality of indentations formed along the first and second layers in a machine direction and in registration with a common bond area between the first and second layers;
- and a second plurality of indentations formed along the first and second layers in the machine direction;
- wherein the first plurality of indentations and the second plurality of indentations are arranged at positions spaced across the first and second layers in a cross-machine direction.
11 more elements
A method, comprising:
- moving a substrate of roofing shingle material along a path in a machine direction, the substrate comprising a first layer and a second layer;
- wherein the first layer comprises:
- a headlap portion, and
- an exposure portion having a plurality of tabs;
- forming a first plurality of indentations in the substrate in the machine direction, the first plurality of indentations configured to attach the first layer to the second layer;
- forming a second plurality of indentations in the substrate in the machine direction to form raised areas that are visible along an upper surface of the exposure portion of the first layer;
- wherein the second plurality of indentations are spaced from the first plurality of indentations across the substrate in a cross-machine direction, and wherein one or more of the second plurality of indentations are positioned in registration with one or more of the plurality of tabs formed in the first layer of the substrate;
- and
- cutting the substrate to form a plurality of roofing shingles.
6 more elements
A stack of roofing shingles, comprising:
- a plurality of roofing shingles, wherein at least a portion of the roofing shingles comprises:
- a first layer including:
- a headlap portion configured to be overlapped by at least one additional roofing shingle arranged in a next higher course of roofing shingles on a roof, and
- an exposure portion having a plurality of tabs;
- a second layer opposite the first layer;
- a plurality of indentations formed in the first and second layers and configured to attach the first and second layers together;
- and
- raised areas along the plurality of tabs of the exposure portion formed from one or more of the plurality of indentations, the plurality of indentations comprising:
- a first plurality of indentations formed in a machine direction;
- and
- a second plurality of indentations formed along each roofing shingle in the machine direction and spaced from the first plurality of indentations in a cross-machine direction;
- and
- wherein at least a portion of the second plurality of indentations are located in registration with the plurality of tabs of the exposure portion.
10 more elements
A roofing system, comprising:
- a roof deck,
- a plurality of roofing shingles positioned on the roof deck, at least a portion of the roofing shingles comprising:
- a first layer including a headlap portion and an exposure portion, the exposure portion having a plurality of tabs,
- a second layer attached to the first layer;
- and
- a plurality of indentations formed in the first and second layers and aligned in a machine direction along the first and second layers;
- and
- raised areas along the plurality of tabs of the exposure portion formed from one or more of the plurality of indentations,
- wherein the plurality of indentations are configured to attach the first layer to the second layer;
- wherein a first plurality of indentations of the plurality of indentations are positioned in registration with a common bond area defined between the first and second layers;
- wherein a second plurality of indentations of the plurality of indentations are spaced from the first plurality of indentations in a cross-machine direction across the first layer and second layer and at least some of the second plurality of the indentions are positioned in registration with the plurality of tabs of the exposure portion of the first layer;
- and
- wherein the roofing shingles are arranged in overlapping courses of roofing shingles on the roof deck with the headlap portion of each roofing shingle in a lower course attached to an overlapping roofing shingle of a higher course of roofing shingles.
10 more elements
A roofing shingle, comprising:
