A roof tile 2 called a flat tile is erected so as to be butted. A waterproof sheet 3 is installed on the lower surface side of the abutting portion of the ends of the adjacent roof tiles 2 to ensure the waterproofness of the abutting portion.

As shown in FIGS. 2 and 3, the waterproof sheet 3 is formed by coating a metal core material 3a such as aluminum with a flame-retardant vinyl chloride resin 3b, and is directed obliquely upward from the upper surfaces of both ends. A plurality of draining pieces 4 are projected. A pair of protrusions 5a are provided at the center, and a fitting groove 5 is formed between the protrusions 5a. The fitting groove 5 is made of a steel plate having a thickness of 0.27 mm or more. The plate 6 is detachably attached so that the upper surface is exposed. A pressing piece 7 is provided so as to project inward from the upper end of each projection 5a, and the pressing piece 7 is brought into contact with the upper surface of the metal plate 6 mounted in the fitting groove 5 so as to contact the metal plate 6. Is held in the fitting groove 5. Of the plurality of draining pieces 4 projecting from the upper surface of the end, the draining piece 4 whose outer end is located at the edge is projected longer than the pressing piece 7 above.

The metal plate 6 detachably attached to the fitting groove 5 is attached to the fitting groove 5 by sliding with respect to the fitting groove 5 as shown in FIG. 4, or as shown in FIG. Thus, one end side is engaged with one pressing piece 7 and the other end side is engaged with the remaining pressing piece 7, so that it is attached by force. Here, even when the metal plate 6 is attached by any of the attaching methods, the pressing piece 7 is brought into contact with the end portion of the upper surface of the metal plate 6 so that the metal plate 6 is easily disengaged from the fitting groove 5 or slightly. It is designed so that it will not be easily moved by external force.

FIG. 6 shows another embodiment, in which the waterproof sheet 3 is installed in the valley portion of the roof, and the fitting groove 5 and The width of the metal plate 6 attached to the fitting groove 5 is larger than that of the above embodiment in consideration of being bent at the valley. If the roof tile 2 is to be laid in a fireproof area or a quasi-fireproof area, a metal plate 6 is attached to the fitting groove 5 so that the adjacent roof tiles 2 can be projected. The metal plate 6 is positioned so that the surface is exposed below the mating portion, and the portion exposed below the abutting portion of the roof tile 2 can be used as a fireproof structure. If the area to be roofed is not a fireproof area or a semi-fireproof area, the waterproof sheet 3 is used without attaching the metal plate 6 to the fitting groove 5, and the fitting groove Depending on whether the metal plate 6 is attached to the 5 or not, one type of waterproof sheet 3 can be used in the area designated as the fireproof area or in the area not designated as the fireproof area. . Here, when the metal plate 6 is attached to the fitting groove 5, for example, even if the metal plate 6 is corroded by adhesively fixing the metal plate 6 to the fitting groove 5 at the construction site using an adhesive. It is possible to ensure waterproofness. Further, when the draining piece 4 located at the end is projected so as to project upward longer than the pressing piece 7, the draining piece 4 on the end side is elastically deformed to the lower surface of the roof tile 2 and is strong. It will be pressed into contact, and high waterproofness can be obtained.
