[0002]
[Prior art]
Conventionally, as this type of roofing material, there are various types such as a long roofing material with a tiled roof, a flat roofing material, and a long metal tile.
[0003]
[Problems to be solved by the invention]
However, although a long roofing material with a tiled roof is good in terms of construction and waterproofness, it has a drawback of poor design because of its monotonous appearance. In addition, the flat roofing material is difficult to lay out, and it is very difficult to connect in the lateral direction. Therefore, a joint member for connection is required, and the construction requires skill. Furthermore, long metal tiles formed by press molding are difficult to work because of the steps, and it is essential to form a roof base such as a horizontal rail.
[0004]
[Means for Solving the Problems]
According to the present invention, in order to eliminate such a defect, the roofing material itself is formed into a rhombus-shaped short body so as to be easy to handle in transportation and construction. The present invention proposes a roof material that has a roof with a good level difference, and furthermore, the lower two sides of the protruding decorative surface material produce a shadow, and exhibit an unprecedented appearance.
