The protrusions (2) provided along the left and right side edges and the rear end edge of the main body (1) not only form a tile pattern, but are also exposed after the roofing work, which is one step lower than the protrusions (2). It functions as a weir against rainwater and the like flowing through the exposed part (6) of the main body (1). That is, the projections (2) can prevent rainwater or the like flowing through the exposed portion (6) from flowing to the side beyond the rainwater.

However, in the conventional thick roof tile shown in FIG. 2, since the exposed portion (6) is formed in a flat shape, rainwater or the like flowing down the exposed portion (6) according to the roof gradient,
There is a possibility that the tiles may penetrate the seam (7) between the protrusions (2) on the side edge of the main body which are juxtaposed in the left-right direction and are adjacent to each other. In addition, the ribs (3) are stably arranged on the existing tiles, and the ribs (3) are provided with the protrusions (2) at the time of roofing so that no gap is formed between the ribs (3) and the exposed portions (6). The notch (8) is formed at a substantially central portion placed directly above, but there is a possibility that rainwater or the like may go to the back of the tile from the periphery of the notch (8).

The present invention has been made in view of the above circumstances, and solves the drawbacks of conventional thick tiles, reliably prevents infiltration of rainwater and the like into seams and the back of tiles, and provides waterproofness. The purpose of the present invention is to provide a thick roof tile that can further increase the height.
