The present invention relates to an inferior-purlin interlocking tile for simultaneously constructing the lower parts of the roofing panes and setting out the long side of the roof, and having several distinct water shoots stemming from the body of the tile. It is characterised in that the tile 1 consists of a one-piece assembly of two parts, upstream 2 and downstream 3, located in the same plane, the upstream part 2 being shaped like the contour of ordinary roofing tiles, the downstream part being a natural prolongation of the undulation troughs 4 of the upstream part. It also relates to its method of manufacture by extrusion-moulding of a mouldable material such as concrete which has not yet hardened, as well as to the roofing using this type of material. <IMAGE>
