A multi-layer laminate roofing shingle having a first sheet with a first marginal edge, an intermediate sheet with a second marginal edge, and a bottom sheet with a third marginal edge. The first sheet has a defined width (L), the intermediate sheet is about 2/3 the width of the first sheet, and the bottom sheet is about 1/3 the width of the first sheet. The first, intermediate and bottom sheets are arranged so that marginal edges coincide with one another. When applied to a roof, the multi-layer laminate shingle creates the appearance of depth on the roof.
