ABSTRACT:
The invention concerns an extruded concrete roof tile of the kind which is designed to be laid in broken bond, is generally rectangular in plan view and has underlying and overlying side lock portions at opposed edges respectively. The upper surface of the tile at the upper end thereof, when on the roof, is recessed to receive the side locks of two similar upper tiles laid in broken bond, and the underlying side lock portion is cut away at the lower end of the tile so that the lower end portion of the tile may lie over the upper surface of the tiles down the roof (in use) to extend beyond the said recessed portions of the lower tiles. The recessed portion is arranged to receive the tile hanging nibs of an identical tile when the two tiles are stacked one upon the other.
