PROBLEM TO BE SOLVED: To provide a working device for a roof, which enables an operation such as a coating operation to be easily and efficiently performed on a metal roof composed of a folded plate and a batten seam. SOLUTION: This working device comprises two parallel sled members with a width slightly greater in dimension than an integral multiple of an interval between crests of the folded plates or the batten seams for forming the metal roof, and at least two supporting members for supporting the sled members in parallel. Either of the sled member or the supporting member is formed as a round bar, and front and rear ends of the sled member are structurally curved upward. COPYRIGHT: (C)2009,JPO&INPIT
