I have one of these with 18' of poles, its one hell of a workout to do 200' of roof line! It works best if you can get out there right after the snow stops, before it freezes together.
ATTENTION! There is a great solution of various ways to cause the snow to slide! Watch various videos on Snow Rake or Snow Razor! You can even make your own if your a handy dandy person! BLESSINGS TO YOU! 😊⛄
