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.
