Metal roof material, roofing structure and roofing method using the same, and metal roof material manufacturing method

摘要

To provide a metal roofing material capable of reducing moisture accumulated between metal roofing materials and reducing the risk of corrosion, and a roofing structure and a roofing method using the same. A metal roofing material includes a front base material, a back base material, and a core material. The front substrate 10 is made of a metal plate, and the front substrate 10 is provided with a box-shaped main body 100 and a flange 110 extending from the main body 100. The flange portion 110 has a front base material such that a metal plate 111 extending from the lower end of the main body portion 100 toward the outside of the main body portion 100 in a direction 100 b orthogonal to the height direction 100 a of the main body portion 100 holds the back base material 11. 10 is formed by being folded back to the back side. The metal roofing material 1 is disposed on the roof base with the flange portion 110 being abutted against the flange portion of another metal roofing material. [Selection] Figure 2
