PROBLEM TO BE SOLVED: To improve waterproof efficiency of a tiling roof by notching a groove in the end of one tile put on the front of the end of the other tile to form a space in an overlap section for overlapping two tiles of the tiling roof. SOLUTION: A tile 12 of a tile substrate 14 extruded from cement slurry is formed as a high functional tile equipped with wiring necessary members 13 such as solar cell, plane antenna, snow-melting apparatus, etc. In order to ensure waterproof efficiency of a roof section 11, in an overlap section of the tiles 12, a groove 21 is notched in the rear of the end of an exposure section 16 of one tile 12 put on the front of a non-exposure section 15 of the other tile 12 to for a space. Then, when rain water, etc., enters a boundary section between the non-exposure section 15 and exposure section 16 of the overlap section of the tiles 12, it is diffused with the space formed by the groove 21 and is drained out to the exposure section 16 side of the tiles 12. Accordingly, while keeping waterproof efficiency in the tiling roof, the lowering of skeleton performance can be prevented. |
