METAL ROOFING MATERIAL, AND ROOFING STRUCTURE AND ROOFING METHOD USING SAME

摘要

A metal roofing material 1 has a front base material 10, a rear base material 11, and a core material 12. The front base material 10 is made from a metal sheet. A box-shaped body part 100 and a flange part 110 that extends from the body part 100 are provided to the front base material 10. The flange part 110 is formed by folding over the rear side of the front base material 10 such that a metal sheet 111 wraps around the rear base material 11, said metal sheet 111 extending outward from the lower end of the body part 100 in a direction 100b that is perpendicular to a height direction 100a of the body part 100. The metal roofing material 1 is disposed on a roof substrate such that the flange unit 110 butts up against a flange part of another metal roofing material.
