Of the standard roof tile JB4 and the first to fourth standard roof tiles JB1 to JB4 are arranged at the corner ridge 3 or the valley 4. The same effect as described above is obtained except that only four types of tiles are required.

Are tiled, and the bottom of the triangular area TJA is four times the working width W of the tiles 5, 5a, and the vertical side is the working length L of the tiles 5, 5a. The triangular area TJA is vertically divided by the working length of the tiles 5, 5a..., And the working area of three tiles 5, 5a. The first standard tile JA1 in which the remaining area obtained by subtracting S is defined as the effective area MS, and the remaining area obtained by subtracting the working area S of two tiles 5, 5a,... From the section area CS of the second-stage region TJA2. The second standard tile JA2 whose area is defined as the effective area MS, and the remaining area obtained by subtracting the working area S of one tile 5, 5a... From the section area CS of the third-stage area TJA3 is defined as the effective area MS. The third standard roof tile JA3,

5 and the first to fifth standard roof tiles JA1 to JA1
Since A5 is disposed at the corner ridge 3 or the valley 4, the same effect as described above is obtained except that only five types of corner tiles or valley tiles are required to be disposed at the corner ridge 3 or the valley 4.

Each of the standard roof tiles F1 arranged at the corner building 3
In F3, JB1 to JB4, and JA1 to JA5, the water return ridges 8 are provided on the hypotenuse portion 7 forming the effective area MS, so that the rainwater entering the corner building 3 can be regulated by the water return ridges 8. Therefore, the operation of installing a sealing member for waterproofing as in the related art can be omitted.

Each of the standard roof tiles F1 to F4 arranged at the valley 4
In F3, JB1 to JB4, and JA1 to JA5, since the sag 13 is provided from the hypotenuse portion 7 forming the effective area MS,
Practical effects are enormous, such that rainwater that enters the roof from the valley 4 can be reliably flowed into the valley 4.
