The valley portions 5 of the roof are configured by being connected in a valley shape via the backup material 4 fixed to the side surface of the roof. 6
Is a tarpaulin made of asphalt roofing,
The roof panels 1 and 1 are individually laid on the entire upper surface of the base plate 2.

Reference numeral 7 is a roof tile, and in this embodiment, a ceramic-type roof tile having a substantially flat plate shape is adopted.
The tarpaulin is raised from the eaves side toward the ridge side on 1, 1 tarpaulin 6. The roof tiles 7 are arranged in the valley portion 5 so that a sealing margin 9 of a certain width is left from the valley line 8 (the connecting end of the base plate 1), and the roof tiles 7 are sequentially wrapped from the lower direction toward the upper direction. Have been raised to do so.
Reference numeral 10 is a waterproof tape attached to the seal allowance 9.

Reference numeral 11 denotes a trough gutter extending along the trough line 8 of the trough 5, and the trough 11 is composed of a large number of trough pieces 12 extending in the trough direction. Each trough piece 12
As shown in FIG. 4, it is formed by bending in a V-shaped cross section along the center of the thin metal plate in the width direction.
A lateral drainage portion 13 is formed on the surface side by being folded.
The upper end of the trough piece 12 in the longitudinal direction (valley line direction) is folded on the front side, and the lower end in the same direction is folded on the back side, whereby upper and lower drainage portions 14 and 15 are formed at the upper and lower ends, respectively. ing.

The trough piece 12 has a length L _{2 in the} same direction as the roof tile 7 which is longer than the length L ₁ in the valley direction.
As shown in FIG. 3, by inserting the roof tiles 7 that have been roofed from the lower end in the valley line direction toward the rear surface side, the overlapping lap portions 16 of the roof tiles 7 sandwich the lower parts on both sides in the width direction. Has been fixed. In addition, 17 is a hanging member, which is hooked to the drainage part 14 of the trough piece 12 and fixed with a nail 18 on the side of the field board 2 so that the upper end of the trough piece 12 is moved to the side of the field board 2. It is fixed.

Further, each trough piece 12 has its drainage part 15
