According to the second aspect of the present invention, the drainage member reliably prevents water from leaking to the ground, and the fixing member securely fixes the exterior material provided with the opening. Therefore, according to the first and second aspects of the present invention, it is possible to provide a drainage structure for a roof that replaces the conventional gutter. In addition, since a gutter is not required, the degree of freedom in design of the eaves is increased.
