ABSTRACT An extruded roof tile 30 has an upper surface 11, which is contoured to give theappearance of a profiled tile and which is, for example provided by projections 30, 34 extending between the upper and lower edges 13 and 14a respectively of the tile, and cm under surface 12 having a shape which is other than a contoured shape which generally follows that of the upper surface 11 of the tile 30. For example, the undersurface 12 may have a shape which corresponds to that of a flat tile. In one method of making the tile 30, a material from which the tiles 30 are made is extruded onto a path which shapes the under surface 12 of tiles 30, the material is compressed to provide the upper surface 11 of tiles 30 with a contoured shape, for example provided by the projections 32 and 34, the under surface 12 of tiles 30 is provided with a shape which is other than a contoured shape which generally follows that of the upper surface 11 of tiles 30 and the contoured appearance of the upper surface 11 of tiles 30 is changed without changing the shape of the under surface 12 of tiles 30.
