Quebec winters are renowned for their extreme temperatures and abundant precipitation. A recurring problem for homeowners during this season is the formation of ice dams on the roof. Not only can these accumulations damage the roof, they also represent a safety hazard for occupants and passers-by. Fortunately, there are effective solutions to prevent this phenomenon.

What is an ice dam?

An ice dam forms when a layer of snow melts on a roof due to heat escaping from inside the house. The water thus created flows to the edges of the roof, where it refreezes due to colder temperatures. This process creates a buildup of ice that prevents the normal evacuation of meltwater, leading to water infiltration under the shingles and, potentially, major structural damage.

The consequences of ice dams

Ice dams can cause a number of inconveniences:

• Water infiltration: Water that can’t drain away freely ends up seeping under the roof sheathing, causing mold, wood rot and ceiling damage.
• Eavestrough sagging: The weight of ice can damage or even topple eavestroughs.
• Danger to bystanders: Blocks of ice can suddenly break off, posing a safety hazard.

Prevention: simple gestures and lasting solutions

The best strategy for avoiding ice dams is prevention. Here are a few things you can do:

• Adequate insulation and ventilation: A well-insulated and ventilated attic maintains an even temperature across the entire roof surface, reducing localized snowmelt.
• Regular roof cleaning: Removing excess snow with a roof rake can limit the formation of ice, especially after heavy falls.
• Installation of heating cables: Roof heating wires are one of the most effective solutions for preventing ice dams. Strategically installed, they create a clear path for meltwater, preventing it from refreezing.

A simple, effective solution: heating wire

Heated wires are designed to activate automatically when the temperature drops to a certain level. They keep roof edges and gutters free of ice. At FilChauffantToiture.ca, we offer high-performance systems that stand up to the rigors of Quebec winters, and are suitable for all types of roofing.

As well as being easy to install, our heating wires can be programmed to operate only when needed, thus reducing energy consumption.

Conclusion

Preventing ice dams means protecting your roof, your property investment and the safety of those around you. Good insulation, regular maintenance and, above all, the installation of heating wires are the keys to a carefree winter.
