Search "ice dam removal" and you'll find people chipping ice with hatchets, blasting it with pressure washers, and pouring boiling water off ladders. Every one of those methods can damage your roof. The professional standard — the only method that removes a dam without harming shingles — is low-pressure steam. Here's how it works and why it matters.

How Steam Ice Dam Removal Works
A commercial ice dam steamer heats water and delivers it as low-pressure steam through a wand. When the steam hits the ice, it melts on contact. The key word is low pressure: unlike a pressure washer, the steamer relies on heat, not force, so it never strips shingle granules or drives water under the roofing. The technician works the dam down methodically and clears the resulting water off the roof.
Steam vs. Every Other Method
| Method | Result |
|---|---|
| Low-pressure steam | Safe. Melts ice cleanly, no shingle damage. |
| Pressure washer | Strips granules, forces water under shingles. |
| Hammer / hatchet / ice pick | Cracks shingles, gouges the roof, voids warranties. |
| Boiling water | Refreezes fast, can worsen the dam. |
| Rock salt | Corrodes metal, harms plants, doesn't fully remove. |
This isn't just our opinion. The University of Minnesota Extension warns that anyone working on a roof in winter — or chipping at ice from below — risks injury and roof damage, and recommends hiring professionals.
Watch the wording: Some companies advertise "steam" but actually use a hot-water pressure washer. A true ice dam steamer runs at low pressure. Ask directly what equipment they use before you book.
Why Not Rent a Steamer and DIY?
Commercial steamers are costly to rent, take experience to operate, and still require you to safely access an icy roof in winter. Between equipment cost and the fall risk, hiring a trained crew is almost always safer and cheaper than going it alone. Our team brings the equipment, removes the dam, and clears your gutters in one visit. Learn more about our ice dam removal service.
After Removal: Keep It From Coming Back
Steam clears today's dam, but the conditions that caused it remain. The Building Science Corporation identifies attic air leakage and insulation gaps as the root cause. Pair removal with heated roof cables and heated gutter cables to keep drainage open, and roof snow removal when snow loads get heavy. See all of our winter services.
