However, the above (1) to (4) are performed while hooking the corner ridge plate arranged in a substantially right angle to the roof material at both ends. A great skill is required in order to construct the board in a satisfactory manner, and there is a risk that water leaks due to variations in the construction, shifts in the flow direction due to external pressure such as snow, and in the worst case, falls. Furthermore, it is necessary to prepare a separate corner ridge plate according to the change in the roof gradient, and if one type of corner ridge plate is forcibly bent and used, stress will concentrate at the center lower end due to the roof gradient. In addition, the corner ridge plate was inevitably exposed and poorly engaged, and there was a danger at the time of construction.
