    摘要: A laminated roofing shingle has an overlay sheet having top surface and bottom surface opposite the top surface. The overlay sheet includes a headlap portion and a butt portion. The butt portion defines a series of tabs and cutouts. An underlay substrate has a top surface attached to the bottom surface of the butt portion of the overlay sheet. The underlay sheet includes a covered portion positioned beneath the tabs of the overlay sheet and a prime portion positioned beneath the cutouts. A layer of reflectivity-increasing granules and/or a layer reflectivity-increasing asphalt, is positioned on only one or both of the tabs of the overlay sheet and the prime portion of the underlay sheet.

    摘要: An exemplary laminated shingle includes an overlay sheet having a top overlay surface, a bottom overlay surface, a headlap portion, and a tab portion arranged between two-cutouts. The shingle also includes an underlay sheet having a top underlay surface and a bottom underlay surface. The overlay sheet is attached to the underlay sheet such that a portion of the top underlay surface is exposed on a first side of the tab portion and a portion of the top underlay surface is exposed on a second side of the tab portion.
