The rainwater that reaches the strip can flow down to the eaves side with the concave strip as a gutter, and it is possible to reduce the leakage of rainwater to the roof basement side at the connection point, as described above.
By using a hook that is fixed to the roof base with a fixture, the watertightness at the connection point of the vertical roofing material is increased, the gutter member is firmly attached to the roof base, and the connection structure is simplified by eliminating the cap at the connection point There is an advantage that performance can be improved.

According to a second aspect of the present invention, the phases of the concave ridges and the convex ridges of the adjacent connecting pieces are shifted from each other. Therefore, in addition to the effect of claim 1, the watertightness between the connecting pieces can be further enhanced by the engagement of the concave ridge and the convex ridge, and the positional displacement between the connecting pieces in the vertical direction. Therefore, there is an advantage that it is easy to connect the adjacent roofing materials almost flush with each other.

In the third aspect, since the lower inner surface of the gutter member is pressed by the lower end surface of the insertion recess, in addition to the effect of the first or second aspect, the mounting strength of the gutter member is further increased. There is an advantage that can be.
