The Factors that Determine Ice Dam Removal Cost and Pricing
Ice Dam Removal Pricing
Generally speaking, you can expect to pay somewhere between $300 to $600 per hour for ice dam removal with steam. As much as you may not want to hear this, with over 25 years of experience behind us, we can tell you that the primary driver for ice dam pricing is classic supply and demand. Every market will have a different demand for ice dam removal and a different supply of qualified contractors to perform that work. (See Econ101 from your freshman year for further details). Back to the word “qualified”. There are dozens of companies in the Twin Cities market right now who are using ice picks and hammers and axes to remove ice dams. They normally charge less per hour than ice dam steaming contractors. There are also scores of competitors using high temperature pressure washers and calling them steamers (hint: 2 of the top 3 Google results in Minnesota). Yikes. In the Minneapolis market we profit by following the work of the aforementioned “professionals” by repairing the damage they’ve done each winter with pics and pressure washers. It’s hurts to pay for ice dam removal. It’s extra painful to pay for repairing the damage left behind by losers.
Ice Dam Removal Speed
There are many factors that go into determining how long an ice dam takes to remove:
- Roof height (Higher = More difficult)
- Roof pitch (Steeper = More difficult)
- Snow load (More snow = More time)
- Site protections time (Property under the work area needs to be protected to prevent damage from falling ice and snow)
- Ice dam thickness (Thicker = More time)
- Ice dam depth (The further it has grown up the roof, the longer removal takes)
- Outdoor temps (Colder = More difficult)
- Ethics (Lower ethics = More time spent)
Having two members to the crew is not only important to safety, it is essential for efficiency. One guy cuts and one guy throws the ice chunks.
To Chunk or Not to Chunk
There is a big difference between ice dam removal COST and ice dam removal PRICING. Pricing is what one typically pays per hour for the work to be performed. Cost relates to how long it takes to do the job. In our list of the 8 factors that determine ice dam removal cost, #8 is the most important. That’s what the photos in this case study are meant to illustrate. Ethical ice dam removal guys do it like shown and they use steam, not high temperature pressure washers. It’s called ‘chunking’. The idea is simple. Use the steamer to cut the ice dam into chunks that can be picked up and thrown off the roof. Cutting ice is the part of the job that takes the longest. Add to cutting time, add to the job cost. The alternative is to use the steamer-or pressure washer if you’re totally smarmy-to methodically melt away ALL of the ice from the roof, one square inch at a time. As shown here, one only needs to actually melt about 5-10% of the ice in order to remove the ice dam. Make slots and undercut. It’s that simple. What the less ethical players do is also simple. Melt all of the ice, milk the clock and watch the dollars add up.

The Truth About Gutters and their Relationship with Ice Dams
In 2011, Ice Dam Company owner Steve Kuhl wrote a nationally published article about ice dams for the Journal of Light Construction. One of the topics that receieved the most attention was the notion that gutters have nothing to do with ice dams. Here is a deeper look at that assertion.
There is a great deal of confusion and misinformation about the relationship between gutters and ice dams. Many people are under the misconception that gutters cause ice dams or that gutters filled with ice can cause water to back up into homes. Not true. We repeat. Gutters have nothing to do with ice dam formation or severity. For this reason, buying systems that heat gutters in order to prevent ice dams is a total and complete waste of money.
We know that ice dams occure when:
- Escaped heat from the inside of the home warms the roof deck.
- Melting snow results in water that runs down to a cold, unheated area of the roof (frequently the eave, as shown below).
- That water freezes, forming ice. After many of these cycles, that ice piles up to form an ice dam.
Study the illustrations below. These are identical eave designs, one with gutters, the other without. The Area B in the diagrams below is referred to as the ‘cold edge’ of the eave because heat from the interior of the home doesn’t travel that far. Fact One: Whether or not a home has gutters, a cold edge will still exist and this is where ice dams form. Fact Two: leaks from ice dams occur in Area A, at the leading, top edge of the ice dam where water–with nowhere else to go–is forced up under the roofing material and into the home. Put another way, if the home in Figure 2 had bad leaks inside, those leaks would not be eliminated whatsoever if we took a chainsaw and cut off the gutters along the red dashed line (C). Moreover, if we heated the gutters using a fancy electrical system, the likelihood of ice dams and the subsequent leaking would NOT be affected. Spend money on heat cables for the lower edge of your roof, not on heating the gutters only. High quality heat cables can be quite effective in preventing ice dams.
Figure 1: Ice Dam Without Gutters; Figure 2: Ice Dam With Gutters
None of this is to suggest that ice in gutters are harmless. We have seen many gutters damaged or destroyed by ice dams and that is a problem most homeowners would like to avoid. The point here is that, all else held equal, if a home is likely to get ice dams the addition or deletion of gutters will be of no consequence to the formation or severity of said ice dams. Likewise, for this reason, installing heated gutters or adding heating systems to existing gutters will have no affect whatsoever on the occurrence or severity of ice dams.

Where Do Ice Dams Normally Happen on Homes? A List of the Most Common Ice Dam Locations
Where ice dams happen…and don’t happen:
- Ice dams seldom occur over unheated areas such as garages and porches (A).
- The valley areas of dormers frequently get ice dams (B).
- Ice dams often occur both below and above skylights. Ice dams above skylights are hard to see from the ground, making them some of the sneakiest to discover (C).
- Any openings through the roof – such as pipes and vents – are a good place for small ice dams for form (D).
- Valleys are very common areas for ice dam formation. It is important to never use hammers or chisels near valleys as the difference between a thorough ice removal job and valley damage is fractions of an inch (E).
- On roofs with a low pitch (angle) even a 1-2″ ice dam can cause significant leaking and interior damage (F).
- The eaves edge is the most common place to see ice dams. 80% of the dams we remove are found here (G).
- Interior rooms with vaulted ceilings are frequently associated with large ice dams. Bathrooms are often the worst. If you had recessed lighting to a vaulted ceiling, you are much more likely to have ice dams (H).
- Ice dams occasionally form around chimneys and furnace flues. Any place heat escapes through the roof line. Ice dams in these locations can be very, very small and still cause leaking (I).

How to Know if You Have an Ice Dam Problem or Just Some Pretty Icicles
Here are six things you can look out for when determining how severe your roof ice dam issues may be:
- Icicles forming on the edge of your roof (with or without gutters).
- Ice begins to build on top of the gutter or lower edge of roof. Remember: Ice dams as little as 1″ thick can cause big problems on certain roods. Don’t be fooled by small ice dams.
- Icicles forming behind the gutter, or worse, behind the facia.
- Ice begins coming through the soffits, normally through vents or through seams in the soffit. This is bad news. Next stop, your ceilings.
- Ice or water shows up on the siding or exterior wall surface. Ice can appear in the anywhere along the wall, even randomly in the middle.
- Ice or water shows up inside your home or around the window frame (interior or exterior). This is really bad news.

Roof deicing cable for ice dam prevention by the Ice Dam Company
Over the years we have heard people call heat cable many things.
Heat Coils for ice dam prevention:
Heat coils most likely get their name from the fact that the material itself, that is the heat cable, comes in coils and when installed by a hack is sometimes left in coils on the roof. Heat coils for ice dam prevention are of course the same thing as heat cables.
Roof deicing cables for ice dam prevention:
Roof deicing cables get their name from their primary purpose, to deice roofs. The name is a bit of a misnomer, however, because technically, roof deicing cables do not deice the entire roof, or even the majority of it. Ice dam deicing cables only melt channels through a small percentage of the ice dam to enable the passage of water through the ice dam so water is not able to back up behind the ice dam, into the roof material and into the home. Roof deicing cable is commonly used in the control of ice dams. Notice that there is a big distinction between preventing ice dams and controlling ice dams. Roof deicing wire and roof deicing cable is not meant to prevent ice dams so much as it is meant to control the affects of ice dams on roofs.
Gutter heat cables, Gutter heat tape and Gutter deicing cable:
Gutter heat tape also known as gutter heat wire, is used in the same fashion as heat cable, heat tape and roof deicing cable. It’s primary purpose is to melt ice, or more specifically, to prevent the original formation of ice in the gutter. As discussed in the here general section, gutters in fact have nothing to do with either the creation or severity of ice dams. This isn’t to say that using gutter heat tape or gutter heat wire is a bad idea. Having hundreds of pounds of ice form in your gutter system causes problems of its’ own, most notably that the gutters can be ripped off the house by the weight of the ice itself. Gutter heating coils is yet another variation of this category of names.

Roof Heat Wire and Roof Heat Coils
As with other names, roof heat wire gets its’ name from the perception of its’ intended function. It’s just another way of saying heat cable or heat tape. Roof heat wire is wire on the roof that carries heat with the purpose of controlling ice dams or the damage created by ice formations on a roof.

HEAT CABLE CLIP COST:
$.78 to $1.22 Per Heat Cable Clip (Traditional, mechanically fastened clip used for standard asphalt roofs)
$25.00 to $35.00 Per Heat Cable Clip (Slotted clip used for slate, tile and cedar roofs)
$.78 to $1.22 Per Heat Cable Clip (Traditional, mechanically fastened clip)
We sell a wide variety of clips, brackets and doohickies for the installation of ice dam heat cable. There are three basic varieties of clips one can buy through the Ice Dam Company.
Roof clips for ice dam heat cables
Mechanically Fastened Heat Cable Clips:
This type of clip is either nailed or screwed onto the roof. It is by far the most common clip sold on The Ice Dam Company website and is used primarily to secure heat cables and roof deicing wire to asphalt roofs. Our installers use these clips to install ice dam heat cable by either nailing or screwing the clips directly to the roof surface, usually in conjunction with a blob of special polyurethane caulk. Once installed, these clips are used to hold the ice dam cable in place permanently without creating wear points that might eventually abrade through the cable and cause issues with functionality. The average cost of these heat cable and roof deicing wire clips for ice dam control is $.78 to $1.22 Per Heat Cable Clip, depending on style, color and order quantity.
Slotted Clips and Brackets for Heat Cable:
As the name suggests, this family of clips is slotted in order to allow installers to use existing fasteners on a roof system to hold the clip in place. The most common application is the slate roof clip or cedar roof clip. Such clips are slipped up, under the existing roofing material and hooked around the nails being used to hold the clip in place. Using slotted heat cable clips is the suggested method of installing heat cable and roof deicing cables on slate roofs and sometimes on cedar roofs because of the non-invasive, non-destructive nature of the install. Slotted roof heat cable and roof deicing clips are far more expensive for ice dam prevention installations than traditional heat cable clips. The average cost of these heat cable and roof deicing wire clips for ice dam control is $25.00 to $35.00 Per Heat Cable Clip, depending on style, color and order quantity. The vast majority of the slotted clips we sell are made of copper and are for use on slate roofs.
Glue-on clips for ice dam heat cable and roof deicing cable:
The third and final style of clips we sell are Glue-on clips. These clips are used on metal and single ply roofing systems, such are EPDM (rubber) and TPO membranes. Installing heat cable and roof deicing wire on metal roofs is not nearly as common as on other systems such as asphalt roofs and slate roofs. Metal roofs are simply less prone to ice dams, or more specifically, to damage caused by ice dams. Single ply systems, or roof membranes like TPO or rubber roofs, are even less likely to suffer from the ill consequences of ice dams. This explains why we sell less of this style of roof clip than any other. The average cost of these heat cable and roof deicing wire clips for ice dam control is $.92 to $4.55 Per Heat Cable Clip, depending on style, color and order quantity.

I was recently interviewed by Realtor Magazine for a piece about preparing home buyers for severe weather –including Ice Dams, why ice dams happen and ice dam prevention methods.
You can read the full Article at Realtor Magazine Here:
Help Clients Prepare for Weather Challenges
The piece also discusses other weather related problems and disasters that can happen from strong winter weather. Check it out. I am frequently interviewed from media and professional sources from all around the country on the topic of ice dams because I started The Ice Dam Company so long ago. We are in fact the largest and the oldest ice dam prevention and ice dam removal company in the country. Before the Ice Dam Company, no other company existed that specialized in this area of business. Now, of course, the web is littered with ‘experts’ and ‘specialists’ purporting to be leaders.
