ABSTRACT:
An interlocking roof tile which can be made by extrusion, pressing or moulding has an upper edge; a lower edge which is visible in use when the tile is laid in overlapping relationship with at least one tile of a next adjacent line of the tiles; an upper surface; a lower surface; a supporting understructure; two oppositely facing side edges; an underlock extending along one of the side edges and an overlock extending along the other of the side edges, the underlock having a lower end and an under surface which forms part of the under surface of the tile, and a lower edge portion having an under surface which includes a part of the under surface of the underlock, and which overlaps, in use, at least one tile of the next adjacent line of the tiles, characterized in that the upper surface of the tile extends continuously from the lower edge to the upper edge, in that the upper and lower surfaces are cambered from the lower edge to the upper edge and are substantially flat when considered in cross-section taken along a line extending between the side edges, in that the lower edge portion including the underlock has a taper which extends in the direction of the lower edge of the tile at least as far as the lower end of the underlock.
