Ice dam removal cost depends on how much roof edge is buried, how high and steep the roof is, how thick the ice has grown and how long a crew needs to steam it safely. No two roofs match, so reputable companies quote after seeing the roof or photos. Compare what is included in writing, not just the total, and weigh it against the water damage a dam can cause.
What sets the ice dam removal cost
Steaming off an ice dam is slow, careful work at height. The quote follows the time, equipment and risk involved. These are the factors that matter most.
- Length of roof edge affected. A dam along one short eave is a small job. Ice running along several sides of a house, or around dormers and valleys, multiplies the work.
- Roof height and pitch. A bungalow is easier to reach than a two-and-a-half storey home. Steep pitches and high eaves need more set-up and more safety equipment, and they slow the crew.
- How much ice there is. Fresh ice is thinner. A dam that has grown through several freeze-thaw cycles can be thick and layered, and it takes longer to cut channels through.
- Snow on top. If a heavy load of snow sits over the ice, it may need to be cleared before steaming can start.
- Access. Fences, decks, garden beds, an attached garage and narrow side yards all affect where ladders and equipment can go. Crews also need a water supply for the steamer.
- Roof condition and material. Old, brittle shingles, skylights, flashing and roof vents call for a lighter touch and more time.
- Eavestroughs and downspouts. If they are packed with ice, freeing them so meltwater can drain adds time but is often needed to make the job last.
- Return visits. A dam that re-forms during the same cold spell may need a second visit. Ask how that is billed before you agree.
None of these can be judged from the street by a stranger, which is why a firm price over the phone with no photos should make you cautious.
How much do ice dam guys charge? Common ways to quote
There is no standard rate card. You may be offered one of these structures, and each suits a different job.
| Quote style | Suits | Ask about |
|---|---|---|
| Flat price for a defined stretch of roof | A clear, bounded problem such as one eave | Exactly which edges are covered and what happens if the ice runs further than expected |
| Hourly rate for crew and equipment | Large or unclear jobs | Crew size, a minimum time, and whether set-up and travel time count |
| Call-out minimum plus time | Short mid-winter emergencies | What the minimum covers and when the clock starts |
The cheapest number is not always the lowest cost. A low offer can mean a quick chip with a hammer, a one-person crew on a high roof, or an exclusion list that adds charges later. A clear scope with a higher total can cost less in the end than a vague offer that ends in a dispute.
How much to steam ice dams, and what a steamer costs you
Professional removal uses low-pressure steam to cut channels through the dam so trapped water can run off, and to release the ice from the shingles. It avoids hammering or chipping, which cracks cold, brittle shingles and bends eavestroughs. That slower, gentler method is what you are paying for. Our guide to removing ice dams safely covers the method in more detail.
Homeowners sometimes ask about the ice dam steamer cost of buying or renting a machine and doing it themselves. Look past the equipment fee. You would also need a water supply, power, and a safe way to work at the roof edge. Steam wands are hot, ladders are unstable on icy ground, and a mistake with the wand can still strip granules or lift shingles. If the job means standing on a ladder against a wet, icy eave, the saving rarely justifies the risk.
If you do try something yourself, stay on the ground. Use a roof rake from below to pull snow off the lower edge, and call a professional for the ice.
Ice dam repair cost compared with the cost of removal
Removal deals with the ice. If water has already got in, repair is a separate job. Wet insulation, stained ceilings, damp drywall, peeling paint and mould can follow, and that repair can be larger than the removal itself. Our page on ice dam water damage lists the warning signs.
The Insurance Bureau of Canada says standard homeowners' policies commonly cover sudden and accidental water damage from ice dams. It also says that ongoing or repeated damage can be treated as a maintenance issue and may not be covered, and that policies vary. Read your own policy, and if water is coming inside, contact your insurer right away to start the claims process. Ask specifically whether the cost of removing the ice is covered or only the damage it causes.
This is the main reason to act early. Ice dam removal is a predictable cost. Hammered shingles, a failed ladder job or a soaked ceiling are not.
What a written estimate should say
When you compare offers, line them up against the same list. A good estimate states:
- which roof edges and how much length are covered
- the method, such as low-pressure steam, and a statement that no chipping or hammering is used
- whether eavestroughs and downspouts will be cleared of ice
- whether raking snow from the lower roof is included
- who removes the loosened ice from walkways and the yard below
- what happens if the ice re-forms, and how a return visit is priced
- who carries the insurance and how you can see proof of it
D&D Snow Services gives a free written estimate for ice dam removal, and insurance and WSIB documentation can be requested. Photos of the roof edge from the ground and from inside the attic help the estimate. After a big thaw or storm, many homeowners call at once, so ask for a realistic booking window rather than assuming a same-day visit.
How to stop paying for ice dams every winter
If the cause stays, the ice returns. A dam forms when heat from the house melts roof snow that then refreezes at the cold eave. Natural Resources Canada advises sealing every attic air leak and insulating thoroughly as the main prevention, with ventilation as a second line of defence. That is a one-time job that can end the yearly bill. See attic insulation and ice dams for what to check.
In the meantime, three cheaper habits help.
- Rake the lower roof edge after heavy snow, from the ground, to reduce the load that feeds a dam. The roof rake guide explains when and how.
- Clear eavestroughs and downspouts in the fall so meltwater has somewhere to go.
- Consider heating cables along the roof edge and through the eavestrough. They do not melt the whole roof. They keep a drainage path open. Running cost depends on cable length and how long it runs.
Pricing out one winter of removals against a fix to the cause is a fair comparison. If you need steaming more than once in a season, the cause is worth chasing.
Ice dam removal cost questions
How much does ice dam removal cost?
It depends on the length of roof edge, roof height and pitch, how thick the ice is, access and crew time. Most professionals quote after seeing photos or the roof. Ask for a written estimate that states the area covered, the method and what happens if the ice returns.
How much do ice dam guys charge, per job or per hour?
Both exist. Some firms price a defined section of roof as a flat job. Others charge for crew and equipment time, or a call-out minimum plus time. Ask which applies, what the minimum covers and whether set-up and travel time count toward the total.
Is it worth buying or renting an ice dam steamer?
Usually not for a one-off problem. Beyond the machine, you need a water supply, power and a safe way to work at the roof edge, and a ladder on icy ground is a real hazard. Hot steam can also damage shingles if used badly. Hiring a trained crew is the safer route.
Does home insurance cover ice dam removal?
The Insurance Bureau of Canada says standard policies commonly cover sudden and accidental water damage from ice dams, but repeated damage may be treated as maintenance and policies vary. Ask your insurer whether the cost of removing the ice is covered, and call right away if water enters.
Does waiting make ice dam removal cost more?
It can. Ice keeps building through freeze-thaw cycles, so there is more to cut, and water backing up under shingles can turn a removal job into a repair job. Do not climb up to fix it yourself. Rake from the ground and book a professional.
