A snow removing device for removing snow and ice from the roof of semi-trailers, vans and similar vehicles. The snow removing device includes; a scraping blade slidably mounted for vertical movement between spaced apart vertical frame posts. A mechanism is provided for automatically adjusting the position of the scraping blade relative to the vehicle's roof so as to maintain a predetermined blade spacing between the blade lower peripheral edge and the vehicle's roof in order to prevent the scraping blade from damaging structures protruding from the vehicle's roof. A resilient skirt extends from the scraping blade so as to fill the spacing there underneath and so as to contact the vehicle's roof. A mechanism is also provided for adjusting the amount of pressure exerted by the scraping blade and resilient skirt on the vehicle's roof depending on the consistency of the snow being scraped. A breaking assembly is further provided for breaking slabs of hardened snow and ice supported on the vehicle's roof. A mechanism is provided for adjusting the height of the breaking assembly. Another mechanism is provided for adjusting the pressure exerted by the breaking assembly on the vehicle's roof.
