It is shifted by 1/2. A gap 3 is provided between the ridge side end of the second adjustment tile 52 and the eaves side end of the third existing flat tile 25.

  After the second adjustment tile 52 is installed on the first adjustment tile 51, the first-stage new flat tile 13 is installed. The first-stage new flat roof tile 13 is a roof tile that is arranged on the most eaves side among the plurality of new flat roof tiles 1.

  The first-stage new flat roof tile 13 is disposed over the second adjustment roof tile 52 and the third-stage existing flat roof tile 25. The arrangement position of the first flat roof tile 13 in the direction perpendicular to the eave building direction is the working width a of the existing flat roof tile 2 in the direction perpendicular to the eave building direction with respect to the arrangement position of the second adjustment tile 52. It is shifted by 1/2 of that.

  When the first flat roof tile 13 is disposed on the second adjustment roof 52, the adhesive 4 is disposed in the gap 3. Thereby, since a clearance gap is formed between adhesives, even when rainwater wraps around the back surface of the new flat roof tile 13 in the first stage, it can be drained to the eaves side. The adhesive 4 is disposed at a plurality of locations in the direction perpendicular to the eaves-ridge direction in the gap 3 with an interval. The adhesive 4 is preferably a foamable adhesive. As the adhesive 4, for example, it is preferable to use a hard urethane foam adhesive.

  Since the adhesive 4 is a foaming adhesive, the adhesive 4 is appropriately expanded inside the gap 3, and the first-stage new flat roof tile 13 and the second-stage existing flat roof tile 24 are connected to the gap 3.
