2. Description of the Related Art In general, a roof of a building is required to have a strong, beautiful roof that is light, does not break, and a metal plate roof has been conventionally known as a material that satisfies this requirement. In a conventional roof with a metal plate, a large number of long roof plates having arcuate connecting portions on the left and right sides of the flat valley are connected in parallel, so that the flat valley and the cylindrical connecting portion alternate. It is what is called a so-called cylindrical thatched roof (see, for example, Japanese Utility Model Publication No. 56-45942), and this conventional cylindrical thatched roof has the beauty of a traditional Japanese roof. It was designed by taking full advantage of its characteristics and matched the roof of a Japanese style building.
