FIELD: construction.
SUBSTANCE: method includes heating of inclined surfaces of chutes of rain and snowmelt runoffs and outer surfaces of building roofs with a heat carrier with subsequent removal of condensate into a sewage system. The heat carrier is represented by air flows from exhaust systems of ventilated heated premises of a building, which are sent into thickness of collecting systems of roofs by means of heat carrier supply channels. Air flows from exhaust systems of ventilated heated premises of buildings are moved forcedly, rain and snowmelt runoffs are removed into a conventional sewage system with the help of rain pipes, which are heated by the heat carrier.
EFFECT: reduced power inputs for heating of collecting systems of roofs.
