A total of three pilot holes 6, 6, and 6 are successively formed at positions corresponding to the corners of the triangle by a drill drill 5 of about m. Then, using the saw 7, each prepared hole 6,
Cuts 8, 8, 8 are made in the plywood 2 so as to connect between 6, 6, and cut off that part to form a triangular ridge ventilation hole 9
Is sequentially formed on each roof panel 1,1,1. In this manner, on-site processing of the ridge ventilation holes 9, 9, 9,... Of the square roof is performed.

Next, in the second step, as shown in FIG. 2, roofing 11, 11, 11,... Are sequentially laid to the lower end of each building ventilation hole 9, 9, 9,. Roofing is performed in this way except for the square roof ridge.

Further, in the third step, as shown in FIG. 2, metal drainage members 12, 12, made of an iron plate or the like are formed in four directions along the lower ends of the ventilation holes 9, 9, 9,.
The stainless steel nails 13, 13,... Are attached one after another.
Enclose the four sides of the ridge ventilation holes 9, 9, 9,. The waste water draining member 12 is processed so that adjacent both ends can be overlapped with each other. In this way, the draining members 12, 12, 12, 12, which surround the ridge portion of the square roof,
Install.

In the fourth step, as shown in FIG. 3, appropriate colored asbestos boards 15, 15, 15,...

In this manner, the ventilation ridge member 21 is attached along the periphery of the drainage drain members 12, 12, 12, 12 surrounding the ridge portion of the rectangular roof, thereby completing the ventilation ridge construction.

In the above embodiment, a triangular ridge ventilation hole is used. However, the present invention is not limited to this. For example, a circular ridge ventilation hole using a forsaw or the like or a square ridge ventilation hole is used. It may be a hole. In addition, the external appearance shape and the like of the ventilation ridge member attached to the ridge portion of the square roof are arbitrary, and it goes without saying that the specific detailed structure and the like can be appropriately changed.

[0020]

As described above, according to the present invention, a ridge ventilation hole is formed in a triangular roof panel forming a square roof in the first step, and the ridge ventilation is performed in the second step. Roofing is laid to the bottom of the hole, and in the third step,
