The parapet is provided to protrude forward from the outer wall, and a soffit is provided between the parapet and the outer wall, and outside air can be introduced into the corner space of the roof through the space between this soffit and the outer wall. It is designed to be carried out through a gap formed in the

(Problem to be Solved by the Invention) However, in such a conventional roof structure of a building, the corner spaces of the roof communicate with the front side of the roof via the rain channels in the valleys of the folded plates. Even if outside air is introduced into the roof corner space from under the eaves, the introduced outside air will escape to the front side of the roof through rain channels. Another problem was that it was difficult for outside air to enter the attic space, resulting in poor ventilation in the attic space.

Furthermore, since a gap serving as a ventilation hole is formed under the eaves, the gap is conspicuous and the structure inside the corner space of the roof can be seen through the gap, resulting in an unsightly appearance.

The present invention has focused on the above-mentioned conventional problems, and aims to provide a roof structure for a building in which the attic space is sufficiently ventilated and has a good appearance.
