Abstract
A roof tile (9) having contoured interlocking regions (20) along its side edges is provided with a plurality of relatively shallow closely spaced, longitudinally extending grooves on its upper surface (19) and optionally upwardly extending grooves on its lower end face (21). An improved appearance on a roof is obtained, and through the provision of dark brown streaks on a light brown base a roof tile may be given a wooden appearance. In a process and apparatus for the manufacture of such tiles, a slipper compressing tile forming material is provided with closely spaced ridges which form the grooves on the tiles.
