Canadian winters can be harsh, especially on your roof. The frigid temperatures, heavy snowfall, and fluctuating weather conditions can create a perfect environment for the formation of ice dams.
These ice dams can cause significant damage to your roofing system and even infiltrate your home, leading to costly repairs. This post will explore what ice dams are, their impact on your roof, and how Godfrey Roofing can help you prevent and address these issues.
What are Ice Dams?
Ice dams are ridge-like formations of ice that build up at the eaves of your roof. 
They occur when snow melts on your roof’s warmer areas, usually due to heat escaping from your home’s interior, and then refreezes at the cooler overhangs.
This refreezing process creates a barrier that prevents the melted snow from draining off the roof. As a result, water gets trapped and can seep into your roofing system, causing damage.
The Impact on Your Roof
Ice dams can have severe consequences for your roof. The water trapped behind the dam can penetrate underneath your shingles, causing leaks and water damage to your attic, ceilings, and walls.
Over time, the excess moisture can lead to mould growth, which poses health risks and requires remediation. Additionally, the ice dam’s weight can stress your gutters and downspouts, potentially causing them to detach or collapse.
The longer the ice dam remains in place, the higher the risks of significant damage to your roofing system and the rest of your property.
Preventing Ice Dams
Prevention is always better than dealing with the aftermath of ice dams. Here are some top tips to help you prevent ice dams from forming on your roof:
Ensure Proper Roof Ventilation
Good attic ventilation is essential in the fight against ice dams. Proper ventilation helps to maintain a consistent roof temperature, reducing the risk of melting snow and ice dam formation.
It is crucial to have a well-designed venting system that allows for adequate airflow through the attic space.
Improve Attic Insulation
Proper attic insulation can prevent heat loss and keep your roof cool.
Without sufficient insulation, warm air from your home can escape into the attic, causing the snow on your roof to melt and contribute to ice dams.
Insulating your attic can help keep the roof’s temperature consistent, minimizing the chance of ice dam formation.
Seal Air Leaks
Identify and seal any air leaks in your attic that may allow warm air to escape. Common areas for air leaks include gaps around pipes, penetrations through the attic floor (such as wiring or vents), and improperly sealed attic hatches.
These leaks can contribute to heat loss and increased snow melting on your roof.
Clean Your Gutters
Regular gutter maintenance is vital in preventing ice dams. Clean your gutters of leaves, debris, and other obstructions to ensure proper water flow. Clogged gutters can lead to water backups, exacerbating ice dam formation.
Consider installing gutter guards to prevent debris from accumulating and limiting water flow.
Attic Snow Removal
Removing excess snow from your roof can help prevent the formation of ice dams. However, it is crucial to remove snow safely to avoid damaging your roofing system. If you remove snow, use a roof rake or hire a professional to perform the task correctly.
Addressing Ice Dam Issues
If you detect an ice dam on your roof, acting quickly is essential. Addressing the issue early can prevent significant damage to your roofing system.
