Abstract: A body portion 100 of a front substrate 10 includes first side surfaces 105 and second side surfaces 106, each of the second side surfaces 106 being arranged at a position protruding toward the outer side along a width direction 100a than the first side surface 105. Each of the first side surfaces 105 includes a side flange 105a. A protruding width of the side flange 105a from the first side surface 105 is equal to or less than a protruding width of the second side surface 106 from the first side surface 105. A metal roofing member 1 is arranged on a roof base while abutting at least the second side surface 106 against a second side surface of other metal roofing member.

Abstract: A metal roofing material according to the present invention comprises: a front substrate 2 having a body portion 20, the body portion 20 being comprised of a metal sheet and being formed into a box shape; a back substrate disposed on a back side of the front substrate 2 so as to cover an opening of the body portion 20; a core material filled between the body portion 20 and the back substrate, the metal roofing material being arranged side by side on a roof base together with other metal roofing materials, wherein at least one edge indicator 22 in the form of protrusion is provided at an edge portion of a top plate 20a of the body portion 20.

Abstract: A metal roofing member 1 is disposed side by side with another metal roofing member on a roof base. The metal roofing member 1 has a box-shaped front substrate 10 made of a metal sheet, a rear substrate 11 disposed on the rear side of the front substrate 10, so as to cover an opening of the front substrate 10, and a core material 12 made from a foam resin and filled in between the front substrate 10 and the rear substrate 11. The front substrate 10 results from forming the metal sheet into a box shape. The front substrate 10 has a side wall portion that is continuous in the circumferential direction and is formed by performing drawing or bulging processing on the metal sheet. The front substrate 10 has a height of 4 mm to 8 mm.
