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.
