Abstract:
1. A method of forming a laminated starter shingle, the method comprising: coating a continuous sheet of shingle mat with asphalt; cutting the coated sheet in a longitudinal direction into a first continuous overlay sheet and a first continuous underlay sheet along a first straight cut line, such that each of the first continuous overlay sheet and the first continuous underlay sheet include parallel upper and lower straight edges defining a uniform height therebetween, wherein the height of the first continuous overlay sheet is greater than the height of the first continuous underlay sheet; aligning the first continuous underlay sheet beneath the continuous overlay sheet such that the lower straight edge of the first continuous underlay sheet aligns with the lower straight edge of the first continuous overlay sheet; laminating the first continuous underlay sheet below the first continuous overlay sheet to form a first laminated sheet; and cutting the first laminated sheet across the height of the first continuous overlay sheet to form a first rectangular starter shingle; wherein the first straight cut line defines the upper straight edge of the first continuous overlay sheet.
