PROBLEM TO BE SOLVED: To provide a roof snow removal device that reduces facilities and maintenance and management processes, mitigates heavy labor of roof snow removal, reduces risks of falling from a roof and others, and prevents a house from collapsing. ! SOLUTION: A roof is covered entirely by a polycarbonate plate 3 that incorporates rods 11 lined up in a vertical direction. A polycarbonate hollow plate 6, connected to an iron plate 4 on the roof top with a spring 5, incorporates on the undersurface a combined member of rods 11 and aluminum pipes 7 in the horizontal direction, so as to make the hollow plate slide over the rods. A thin film-like mat 13 that encapsulates lubricant oil is fixed on the polycarbonate hollow plate, and a weatherproof sheet 12 connected to the iron plate with a spring at the edge is laid. The sheet slides on the slanted roof downward due to the weight and pressure of snow on the roof, which resist against the spring. A foot section supporting a snow dividing plate 8 on the r |
