By holding the holding member 12 with the holding portion 12a of the fixing member 12, a plurality of fixed-size roof shingles 6 are connected in the flow direction.

In such a configuration, even if rainwater intrudes from the connecting portion B in the flow direction (see FIG. 6), the rainwater is received by the joint discard plate 11, and the rainwater is received from the end 11a. It is discharged to the flowing water space A of the gutter member 3. Also, even if rainwater overflows from the joint waste plate 11 or dew condensation water is generated on the back side of the roof plate 6, these waters are received by the water leakage prevention plate 5, After all it is discharged to the eaves direction. Therefore, even with such a simple connection structure, it is possible to reliably prevent water leakage to the indoor side.

In each of the above embodiments, the lower support member 41 is used.
The flow space A is formed by the gutter member 3 which constitutes a part of the lower surface. However, by forming the lower support member 41 itself as a long material, the groove 41a is formed in the flow space A.
Thus, the gutter member 3 can be omitted.

In addition, the purlin material 1
Although the field material 2 is laid on the roof, the present invention is not limited to this, and the field material 2 can be configured on a roof foundation such as an RC structure.
