To obtain a disconnection implement which enables effective work by a small force when the disconnection implement is inserted to prevent rainwater or the like from staying on the coating in the overlapped part of the roof material, or when the disconnection implement is moved from side to side to separate the overlapped roof materials on the coating part of a large roof surface at the time of repainting the roof material.

The disconnection implement is used for separating the overlapped roof materials in the coating part in the overlapped part of the roof materials at the time of repainting the roof materials by using the action of a lever. The disconnection implement comprises a cutter part, a grip part, and a fulcrum part. The cutter part, which is at the front of the implement, is inserted to the overlapped part of the roof materials. Then the grip part is provided at the rear end part of the body, and the fulcrum part becomes a fulcrum of the action of a lever at the bottom of the cutter part. Then a certain angle is provided about a base point which is a connection between the cutter part and the grip part provided at the end of the body.
