METALLIC ROOF MATERIAL, ROOFING STRUCTURE USING THE SAME, ROOFING METHOD, AND METALLIC ROOF MATERIAL MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a metallic roof material capable of reducing moisture content staying between metallic roof materials, and reducing a risk of corrosion, a roofing structure using the metallic roof material and a roofing method.SOLUTION: A metallic roof material 1 comprises: a front substrate 10; a rear substrate 11; and a core material 12. The front substrate 10 is made of a metallic plate, and the front substrate 10 is provided with a box-shaped main body part 100 and a flange part 110 extended from the main body part 100. The flange part 110 is formed such that a metallic plate 111 extending from the lower end of the main body part 100 to the outside of the main body part 100 in a direction 100b orthogonal to a height direction 100a of the main body part 100 is folded back to the rear side of the front substrate 10 so as to embrace the rear substrate 11. The metallic roof material 1 is disposed on a roof base such that the flange part 110 is butted to the flange part of the other metallic roof material.SELECTED DRAWING: Figure 2
