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.
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.

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.
Frequently Asked Questions
How does steam ice dam removal work?
A specialized machine heats water into low-pressure steam, which melts the ice on contact. The low pressure means it removes ice without harming shingles, unlike a pressure washer.
Is steam better than a pressure washer for ice dams?
Yes. A pressure washer uses high pressure that can strip shingle granules and force water under shingles. A true ice dam steamer uses low pressure and heat, which is safe for the roof.
Will steam damage my shingles?
No. Low-pressure steam melts ice gently and is the method recommended by roofing professionals because it doesn’t crack, gouge, or strip shingles.
Can I rent a steamer and do it myself?
Commercial ice dam steamers are expensive and require training plus safe roof access in icy conditions. For most homeowners, hiring a professional crew is safer and more cost-effective.
