How to Prevent Ice Dams on Your Ottawa Roof

Winter in Ottawa often brings the challenge of ice dams forming on roofs. These ice formations can cause significant damage if left unattended, leading to water leaks and structural issues. 

As the trusted roofing experts at Stewart Roofing, we understand the importance of preventing ice dams and protecting your home. This blog post will share tips for preventing ice dams on your Ottawa roof.

What Are Ice Dams?

Ice dams are ridges of ice forming along the roof’s edge, preventing melted snow from draining off the roof. Ice Dams.

Ice dams can also lead to icicles, which pose a risk to people and pets below. It’s essential to take preventive measures to avoid the formation of ice dams and safeguard your property.

Insulate Your Attic

Insulating your attic is one of the most effective ways to prevent ice dams. When your attic is poorly insulated, it allows warm air to escape from the living space below, melting the snow on the roof. 

This melted snow then refreezes when it reaches the colder edge of the roof, creating an ice dam. Proper attic insulation can keep the warm air inside your home and prevent the snow on the roof from melting.

Ensure the insulation is at the recommended R-value for your climate when insulating your attic. The R-value is the resistance of the insulation to heat flow, and the higher the R-value, the better the insulation’s performance. The recommended R-value for attics in Ottawa is between R-50 and R-60.

Properly insulating your attic will help prevent ice dams, conserve energy, and reduce heating costs. Consult with a professional roofer, like Stewart Roofing, to assess your current insulation and make any necessary improvements.

Improve Ventilation

Proper ventilation is another essential aspect of preventing ice dams. Ventilation helps maintain a consistent temperature in your attic, preventing the excessive buildup of heat that contributes to ice dams. When the air in your attic is too warm, it can melt the snow on the roof, leading to ice dams forming along the gutters.

Proper attic ventilation includes both intake and exhaust vents. Intake vents allow cold, outside air to enter the attic, while exhaust vents allow warm air and moisture to escape. This airflow removes warm, moist air from your attic and replaces it with cold, dry air.

A professional roofer can assist in evaluating and improving the ventilation in your attic. They can ensure that the vents are installed correctly, that there are enough vents to provide adequate airflow, and that the vents are not blocked by insulation or debris.

In addition to preventing ice dams, proper attic ventilation can prolong your roof’s lifespan and prevent mould and mildew growth.

Clear Snow from the Roof

Promptly removing snow from your roof after a snowfall can help prevent the formation of ice dams. Use a roof rake with a long handle to cautiously remove the snow without damaging theIce dams. Men Clean The Roof From Snow to prevent ice dams. shingles or the roof’s structure. 

Start from the roof’s edge and work your way up, gently pushing the snow down. This method prevents the snow from accumulating along the roof’s edge, reducing the chances of ice dam formation.

It’s important to note that removing snow from a roof can be dangerous and may only sometimes be practical. 

If you are not comfortable or can safely remove snow from your roof, it’s best to consult a professional roofer to perform the job. Regular snow removal throughout the winter can greatly minimize the risk of ice dams.

Keep Gutters Clean

Gutters play a crucial role in directing water away from your roof. When gutters become clogged with leaves, debris, or ice buildup, water gets trapped and freezes, contributing to the formation of ice dams. 

Regularly clean your gutters to ensure that water can flow freely. Remove debris, leaves, or ice buildup from the gutters to prevent blockage.

Additionally, consider installing gutter guards to prevent debris from clogging the gutters in the first place. Gutter guards are installed over your gutters, preventing leaves, branches, and other debris from accumulating. Maintain clean gutters to prevent ice dams and water backup issues.

Install Heat Cable

Heat cables are another way to prevent ice dams. Heat cables distribute heat along the roof’s edge, preventing melted snow from refreezing and forming an ice dam. 

Heat cables are typically installed in a zig-zag pattern along the roof’s edge and are best installed by a professional roofer.

Remember that heat cables should not be relied upon as the sole method of preventing ice dams. Heat cable installation should be combined with proper insulation and ventilation for maximum effectiveness.
