Abstract
A laminated asphalt shingle including a base layer, a first decorative layer, and a second decorative layer is provided. The first decorative layer may be affixed to the base layer and to the second decorative layer by a flexible adhesive that permits the first decorative layer to move relative to both the base layer and the second decorative layer without de-bonding. The relative movement of the shingle layers permits the shingle to be folded over the ridge line of a roof without de-bonding or breaking the layers. Additionally, the relative movement of the layers when the shingle is installed over a ridge creates opposing transverse edges in which each layer is offset from the other layers as a result of the shingle bending about a different radius of curvature, thereby providing a dimensional appearance along the transverse edges.
