PROBLEM TO BE SOLVED: To propose a fitting type roofing material capable of surely draining rainwater inevitably from a seam to the outside without leaking it indoors, and a joint structure of the roofing material. SOLUTION: One roofing material main body and the other roofing material main body to be connected adjacent to each other are arranged adjacently and joined by fitting a lower gutter and an upper gutter provided on their respective side edges. An idle space is provided between the side ends of the roofing material main body, and a hidden gutter is arranged along the side edge of the long side of the roofing material main body in the idle space, and the hidden gutter is provided. A fitting type roofing material using an outer skin material constituting the outer surface of the roofing material main body on the side where the lower gutter is formed is integrally molded into a groove shape in cross section by extending the end face on the roofing material main body side and its joining Construction.
