Therefore, the amount of moisture accumulated between the side flanges 105a can be suppressed. Further, since the metal roofing material 1 is provided with flanges (side flange 105a, ridge side flange 107c, and eaves side flange 108a), a gap is formed between the back base material 11 and the roof base. As a result, the amount of water remaining on the back side of the metal roofing material 1 can be reduced, and the risk of corrosion can be further reduced.
- moisture may enter the ridge side of the metal roofing material 1 due to, for example, strong winds.
- the inclined portion 107b is provided on the ridge side end surface 107, the moisture that has entered the ridge side is guided to the abutting portion of the second side surface 106 by the inclined portion 107b, and the moisture gradually moves toward the eave side through the abutting portion. Can be discharged.

- the eaves side end portion (the side end 109a of the eaves side flange 108a) of the ridge side metal roofing material 1 is positioned above the first side surface 105 and the side surface flange 105a of the eaves side metal roofing material 1,
- the metal roofing material 1 on the ridge side is overlaid on the metal roofing material 1 on the eaves side.
- an external force such as a strong wind starts from the end of the eaves side of the metal roofing material 1 on the ridge side. Try to warp.
- the ridge-side metal roof is arranged such that the second side face 106 of the ridge-side metal roof material is positioned above the ridge-side end of the eave-side metal roof material 1 (side end 109a of the ridge-side flange 107c).
- the material 1 is stacked on the metal roof material 1 on the eaves side.
- the metal roofing material 1 is piled up, so that the possibility of moisture entering the building side of the eaves-side metal roofing material 1 through the gap between the building-side metal roofing materials 1 is reduced.
- the inventor made a prototype of the metal roofing material 1 as a test material under the following conditions.
- the material of the front substrate 10 was a coated hot-dip Zn-55% Al-plated steel sheet, a painted hot-Zn-6% Al-3% Mg-plated steel sheet, or a painted hot-Al plated steel sheet having a thickness of 0.20 to 0.6 mm.
- As the back substrate 11 0.2 mm glass fiber paper, 0.2 mm Al vapor-deposited paper, 0.2 mm PE resin film, 0.1 mm Al foil or 0.27 mm painted hot-dip Zn plated steel sheet was used.

Since the force by which the fastened upper roof material presses the lower roof increases, both the upper roof and the lower roof are less likely to be deformed. As a result, durability (wind pressure resistance) is improved. Further, the flanges 107a, 108b and 105a surrounding the four sides of the roofing material improve the flatness of the roofing material itself, and have an effect of suppressing initial warpage and twist, and the gap between the upper and lower roofing materials accompanying them.
