PROBLEM TO BE SOLVED: To solve the problem that snow lumps accumulated on a roof during winter in heavy snow areas are removed by human power dropping them to the ground and carrying them out, imposing a big burden on the residents in these areas. SOLUTION: A roof structure is made to be a tilted-structure, and when a wood material is used, the surface is applied with a water-proofing coating, and when a metal material is used, the roof structure is constituted of a colored steel sheet, a galvanized steel sheet or the like. A heating plate is arranged in contact with the roof surface, and the heating plate is energized and heated or heated by hot water, causing only the bottom surface of the snow lump being a part thereof to be melted and the snow lumps to be dropped to the ground.
