A trilaminate a trilaminate shingle, having a horizontal longitudinal orientation, includes an overlay sheet having series of tabs and cutouts extending horizontally across the shingle. The shingle also includes a middle sheet having a series of tabs and cutouts extending horizontally across the shingle. The middle sheet cutouts are narrower horizontally than the overlay cutouts. The shingle also includes an underlay sheet beneath the middle sheet. The middle sheet is laminated beneath the overlay so that portions of the middle sheet, including at least some of the middle sheet cutouts, are exposed through the overlay cutouts. The underlay is laminated beneath the middle sheet so that portions of the underlay are exposed through the middle sheet cutouts and through the overlay cutouts. The exposed portions of the underlay sheet are generally darker than the middle sheet.
