(54) Improvements in roofing tiles and tiled roofs


(57) A roofing tile or "artificial slate" (1) has a first side lock portion (2) including upwardly facing channels and a second side lock portion (19) including a downwardly facing channel (20). The tile also has a head lock (3) and a downwardly extending lower end wall (22). A series of interconnected holes (11) is provided in the first side lock and a single hole (18) is provided in the head lock. When the tiles are arranged on a roof in mutually overlapping relationship, the side lock (2, 19) of sideways adjacent tiles interengage and the lower end walls (22) overlie the head lock (3) of downwardly adjacent tiles. Nails passing through one of the interconnected holes (11) and the holes (18) of downwardly adjacent tiles secure the tiles to a roof structure and the series hof holes (11) permits adjustment of the amount of overlap between downwardly adjacent tiles.
