Abstract
A multi-layered shingle includes an underlay sheet having a longitudinally extending axis and a leading edge. The underlay sheet further defines a first layer and a second layer. The second layer is connected to the first layer along a first longitudinally extending fold line and folded against the first layer. An overlay sheet is bonded to the underlay sheet, and the first and second layers of the underlay sheet define multiple layers of a multi-layered shingle.
Claims20
A multi-layered shingle comprising:
- an underlay sheet having a longitudinally extending axis, the underlay sheet having a leading edge and defining a first layer and a second layer, the second layer connected to the first layer along a first longitudinally extending fold line and folded against the first layer;
- and
- an overlay sheet bonded to the underlay sheet, the first and second layers of the underlay sheet defining multiple layers of a multi-layered shingle.
A multi-layered shingle comprising:
- a shingle substrate having a longitudinally extending axis, the shingle substrate having a leading edge and defining a first layer and a second layer, the second layer connected to the first layer along a first longitudinally extending fold line and folded against the first layer, the first and second layers of the shingle substrate defining multiple layers of a multi-layered shingle.
A method of forming a multi-layered shingle comprising:
- forming a first longitudinally extending fold line in a shingle substrate having a longitudinally extending axis, the first longitudinally extending fold line dividing the shingle substrate into a first portion and a second portion;
- folding the shingle substrate along the first longitudinally extending fold line such that the second portion is folded against the first portion, thereby defining first and second layers of a multi-layered shingle.
