Large temperature force washers will make one thing approaching steam for 1 or 2 minutes but then the temperature quickly drops off all the way down to all around one hundred fifty°F. When you don’t see at the least 225°F, you’re not addressing a steamer, you’re handling a higher temperature stress washer. Poor news.

Negatives: Only efficient for eliminating unfastened snow. Not efficient for eradicating ice dams which have by now shaped.
It really is almost always cheaper to stop ice dams than to remove them or restore the damage they cause. As soon as an ice dam has formed, removal results in being labor intense, time delicate and pricey.
