Understanding Ice Dams

Ice dams happen when there’s sustained and heavy snowfall paired with unnatural temperature variations in your attic and on your roof. Here’s a good rundown of how ice dams are formed and what happens when one is left unattended.

Snow, So Much Snow!

The first step in the formation of an ice dam is the accumulation of snow on the roof. Usually this won’t happen with run of the mill storms, but more significant weather events. Think big blizzards that dump a ton overnight or when you get sustained storms for several days. The term “unrelenting” comes to mind.

Uneven Roof Temperatures

For an ice dam to form, there needs to be a temperature differential on the roof’s surface — warm in some areas and cold in others. The higher peaks of the roof tend to be warmer (heat rises) compared to the edges where there is no insulation.

This temperature difference is often due to heat escaping from the house into the attic, which then warms the roof above. Inferior attic insulation and attic bypasses allows this warm interior air to seep into the attic, so you’ll want to look into a home energy audit from a local professional. They’ll be able to point out where you have these leaks so you can repair them before next winter!

The Melting and Refreezing Cycle

The snow on the warmer part of the roof (usually the top or near the ridge) melts and flows down towards the colder edge of the roof (eaves). When this water reaches the colder edge, it refreezes, forming a dam of ice. This is made worse if your gutters are already clogged prior to the storm. When gutters are clogged, even snowmelt has a hard time exiting the roof, so it begins to pool on the roof’s eaves. This adds more water to the problem which freezes to the ice dam and makes it even bigger!

Risk for Household Damage

The standing water that pools when dams thaw can seep under the shingles and into the structure of the house, potentially causing damage to walls, leaking ceilings, insulation, and other areas. Keep in mind anywhere that gets soaked or saturated will also need to be checked and monitored for mold. In addition to causing water damage, ice dams can also create a weight burden on the roof and gutters, potentially leading to structural issues.

To prevent ice dams, it’s important to ensure adequate attic insulation and ventilation, which helps maintain a more uniform roof temperature, and to remove snow from the roof after heavy snowfalls if it’s safe to do so. Keep in mind that ice dam removal is not a solution to the underlying issue. You need to seek a professional home energy audit to identify the specific bypasses and issues.

Ice Dam Removal in Montréal and Québec City

Established in 1995, the Ice Dam Guys® have trekked onto thousands of ice roofs just like yours. Over those winters we had time to experiment and make adjustments until we discovered the optimal, safest way to eliminate ice dams – 100% steam. We’re such believers in the superiority of steam that we custom-built our own line of steam machines, aptly named Steamzilla™.

The key benefit of using 100% steam for ice dam removal lies in its non-invasive nature, ensuring your roof remains unscathed by harsh heat or abrasive wear and tear. Our team’s approach can be compared to effortlessly slicing through butter with a heated blade. They segment the ice dam into smaller pieces, making it easier to clear away, as you can see below.

A technician for Ice Dam Guys slices and dices a large section of ice on a roof, known as an ice dam, using steam. He's been able to cut this slab of ice into small handheld sized pieces for easy removal.

Pretty cool, right?! We were able to take an ice dam that was several feet deep and many inches thick and reduce it into handheld tiles. The image above perfectly showcases the efficiency of our 100% steam-based ice dam removal method. This approach not only safeguards your home but also swiftly addresses the ice dam issue, even in the chill of winter.
