FIELD: construction.
SUBSTANCE: snow from a roof surface is blown with a compressed air jet by means of a flexible hose manually aligned with a rigid tubular tip connected to a pipe fixed on the roof of the building and aligned along its length, and the pipe is joined with a compressor located in the building attic, besides, the pipe is arranged with draining nozzles with valves with the possibility to connect the specified flexible hose to them and the possibility to fix a safety device for an operator on a pipe, so that it could move along the pipe as snow is being removed from the roof.
