[0003] However, in this method, the edge of the decorative surface of the roofing material is hooked and constructed, and rainwater infiltrates into the inside from the hooked portion by capillary action.
There was a defect that the base was corroded. In addition, molding is very difficult, and the valley body itself has no waterproofness at all, and the gutter-shaped member existing at the bottom only functions as a flowing water channel. Furthermore, there is no valley-filled structure that can be used for stepping roofing materials and has good workability and waterproofness.

[0004] In order to eliminate such disadvantages, the present invention provides:
A long valley gutter having two waterproof pieces protruding upward is fixed to the valley, and one end of the roof material is hung downward to form a drooping piece. The valley roofing material is fixed so as to be located substantially at the center between the valleys, and a caulking material is planted between the hanging pieces of the valley roofing material. The present invention proposes a valley-filled structure that forms a heavy waterproof structure, exhibits an unprecedented valley waterproofness, and has improved workability and aesthetics.
