Taking down some ice dams today! Check out this video explaining a little of what goes into effective ice dam removal. The steam our machine produces cuts the ice really fast at very low pressure. First We use steam to cut the ice into chunks. Then we melt the underside of the ice to release it from the shingle. It looks like we are using pressure but its just steam vapor making it look like pressure. I wish I had 3 hands so I could make a better video haha! | Sean's Property Services LLC
