Laminated starter shingle for a roof covering

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 lower straight edge of the first continuous underlay sheet.

• cutting the coated sheet in a longitudinal direction into a second continuous overlay sheet and a second continuous underlay sheet along second and third straight cut lines, such that each of the second continuous overlay sheet and the second continuous underlay sheet include parallel upper and lower straight edges defining a uniform height therebetween, wherein the second straight cut line separates the first continuous overlay sheet and the first continuous underlay sheet from the second continuous overlay sheet and the second continuous underlay sheet;
• aligning the second continuous underlay sheet beneath the second continuous overlay sheet such that the lower straight edge of the second continuous underlay sheet aligns with the lower straight edge of the second continuous overlay sheet;
• laminating the second continuous underlay sheet below the second continuous overlay sheet to form a second laminated sheet;
• and
• cutting the second laminated sheet across the height of the second continuous overlay sheet to form a second rectangular starter shingle;
• wherein the second straight cut line defines the lower straight edge of the first continuous overlay sheet.
