〔The invention's effect〕

The present invention has the above-mentioned configuration, and the roofing board is laid on the roof underlayer structure in which the tree provided with the drainer and the waterproof plate arranged between the trees are integrally formed. For this reason, rainwater that infiltrates from the joint part of the thatching plate always travels from the drainer to the waterproof plate, and flows to the ventilation drainer connected to the waterproof plate on the eaves side and is drained from the opening on the lower side. In addition, even if it says that the rafter and the waterproof plate are in close contact, since they are not jointed by means such as a fan assembly, they will not be flooded by the capillary phenomenon from this connection part, and further, they will not be affected by the expansion and contraction or vibration of the building frame, An independent waterproof layer can be configured.

In addition, air can freely flow from the eaves to the ridge and simply dries the moisture that tends to accumulate on the back of the roof to prevent dew condensation, improving the corrosion resistance and durability of the roofing board and roof substructure, and also effective for indoor air conditioning. Bring Further, the roofing board is fixed to the rafter with a hanging member or a screw, and there is a wide range of applications in which the conventional roofing board for lateral thatching can be used in its original shape.

In addition, the ventilation ridge board in the ridge has a slight gap between the ventilation front plate and the ventilation back plate, and since the ventilation holes are opened at alternate positions, rainwater sprayed from the outside is not ventilated. Even if water enters from the ventilation holes of the board, it will be stopped by the board after ventilation and will not enter the inside of the building. Air can freely flow through the ventilation holes in the front and rear ventilation plates, and allows smooth ventilation on the back of the roof.
