To make it possible to easily roof a house with tiles by properly preventing the incursion of rain drops even if there are some gaps between hanging sections.

Pantiles 10 are arranged in vertical rows on a roof in a state to hold a projection 26 projected to the end face of a hanging section 18 in each of the pantiles 10 (equivalent to tiles with hanging sections) in a notch 36 formed in the end face in the pantile 10 adjacent thereto. Accordingly, rain drops flowing down along the surface 42 of the hanging section 18 and going to enter from gaps between hanging sections 18 can not flow to the rear 46 side of the hanging section 18, but it is always dropped at the surface 42 side by gravity.
