However, the above (1) to (3) have a construction in which the roofing material in the corner ridge is sandwiched between the siding plate (scraping plate) and the cover, and there are many members, resulting in inefficiency in construction and cost increase. Although it has drawbacks and lacks in waterproofness, the above-mentioned ~ are to be constructed by hooking the corner ridge boards arranged in a substantially right angle shape on the roof materials at both ends,
It takes a great deal of skill to install the roofing material and the corner siding that come in at both ends in a well-fitted manner.In addition, water leakage may occur due to variations in construction, or the pressure may shift in the flow direction due to external pressure such as snow. There was a risk of falling.

[0004]

In order to eliminate such drawbacks, the present invention puts emphasis on the landscape by housing the descending corner ridge with each step of thatching material, and connecting with the left and right roof materials is a joint material. To improve waterproofness and design, and by connecting the turning and roofing materials to each other by fitting the locking piece and the engaging piece, the workability is improved and the detachment due to external pressure is also performed. We propose a down-corner ridge structure that can prevent moisture and promote the humidity control function by the triangular voids formed between the backing material and the roof substrate.
