Abstract
One aspect of the disclosure is roofing shingle including a shim layer having a top surface, a first side edge, and a second side edge positioned opposite the first side edge. The roofing shingle also includes a top shingle layer at least partially laminated to the top surface of the shim layer, where the top shingle layer includes a first side edge offset a sidelap distance from the first side edge of the shim layer such that a side portion of the top surface of the shim layer is exposed, and a second side edge extending beyond the second side edge of the shim layer so as to overlap the second side edge of the shim layer by the sidelap distance.
Claims20
A roofing shingle having a headlap zone disposed above an exposure zone, the roofing shingle comprising:
- a shim layer having a top edge, a bottom edge disposed in the exposure zone, a top surface, and a connecting portion adjoining the top edge and connecting a series of tabs, wherein the series of tabs includes a series of gaps separating adjacent tabs in the series of tabs, wherein each gap in the series of gaps extends lengthwise from the bottom edge of the shim layer to the connecting portion;
- a top shingle layer at least partially laminated to the top surface of the shim layer, wherein the top shingle layer comprises a top edge disposed in the headlap zone, a bottom edge disposed in the exposure zone, a headlap portion adjoining the top edge and connecting a series of dragon's teeth, wherein the series of dragon's teeth includes a series of spaces separating adjacent dragon's teeth in the series of dragon's teeth, wherein each space in the series of spaces extends lengthwise from the bottom edge of the top shingle layer to the headlap portion, and wherein the shim layer and the top shingle layer are aligned such that each dragon's tooth in the series of dragon's teeth covers a corresponding gap in the series of gaps,
- wherein each dragon's tooth in the series of dragon's teeth comprises a first side edge and a second side edge defining a first width therebetween, wherein the first width is greater than a second width of the corresponding gap.
A roofing shingle having a headlap zone disposed above an exposure zone, the roofing shingle comprising:
- a shim layer having a top edge, a bottom edge disposed in the exposure zone, a top surface, and a connecting portion adjoining the top edge and connecting a series of tabs, wherein the series of tabs includes a series of gaps separating adjacent tabs in the series of tabs, wherein each gap in the series of gaps extends lengthwise from the bottom edge of the shim layer to the connecting portion;
- a top shingle layer at least partially laminated to the top surface of the shim layer, wherein the top shingle layer comprises a top edge disposed in the headlap zone, a bottom edge disposed in the exposure zone, a headlap portion adjoining the top edge and connecting a series of dragon's teeth, wherein the series of dragon's teeth includes a series of spaces separating adjacent dragon's teeth in the series of dragon's teeth, wherein each space in the series of spaces extends lengthwise from the bottom edge of the top shingle layer to the headlap portion, and wherein the shim layer and the top shingle layer are aligned such that each dragon's tooth in the series of dragon's teeth covers a corresponding gap in the series of gaps,
- wherein a first side edge of each dragon's tooth is attached with adhesive to a side edge of a first tab positioned on a first side of the corresponding gap, and wherein a second side edge of each dragon's tooth is attached with adhesive to a side edge of a second tab positioned on a second side of the corresponding gap.
A roofing shingle having a headlap zone disposed above an exposure zone, the roofing shingle comprising:
- a shim layer having a top edge, a bottom edge disposed in the exposure zone, a top surface, and a connecting portion adjoining the top edge and connecting a series of tabs, wherein the series of tabs includes a series of gaps separating adjacent tabs in the series of tabs, wherein each gap in the series of gaps extends lengthwise from the bottom edge of the shim layer to the connecting portion;
- a top shingle layer at least partially laminated to the top surface of the shim layer, wherein the top shingle layer comprises a top edge disposed in the headlap zone, a bottom edge disposed in the exposure zone, a headlap portion adjoining the top edge and connecting a series of dragon's teeth, wherein the series of dragon's teeth includes a series of spaces separating adjacent dragon's teeth in the series of dragon's teeth, wherein each space in the series of spaces extends lengthwise from the bottom edge of the top shingle layer to the headlap portion, and wherein the shim layer and the top shingle layer are aligned such that each dragon's tooth in the series of dragon's teeth covers a corresponding gap in the series of gaps,
- wherein a first side edge of each dragon's tooth overlaps a side edge of a first tab positioned on a first side of the corresponding gap creating a first joint, and wherein a second side edge of each dragon's tooth overlaps a side edge of a second tab positioned on a second side of the corresponding gap creating a second joint.
