ABSTRACT:
A lightweight roofing shingle or tile having an elongated body with top and bottom surfaces that taper lengthwise of the body, the body having laterally spaced, elongated edges; the body having a mid-region and a recess sunk upwardly into the mid-region, from the bottom surface; the recess extending widthwise of the body to intersect the body laterally spaced edges whereby the recess is adapted to receive a batten to support the body mid-region when installed on a roof. A secondary taper on the tile bottom surface engages the roof to provide leverage resisting wind up-lift forces exerted on the lightweight tile acting to rotate the tile about a nailing point fulcrum.
