In this article, we explained some tips to help you prepare your roof for Calgary’s winter: 

Why is it important to prepare my roof for Calgary’s winter?

Here are some tips on why preparing my roof for a Calgary winter is important:

1. Inspect Your Roof

Before winter arrives, inspect your roof for any signs of damage, such as missing or damaged shingles, cracked flashing, or clogged gutters. Repair any damage promptly to prevent water leaks and ice dams.

2. Clean Your Gutters

Clogged gutters can prevent water from draining properly, leading to ice dams and water damage. Clean your gutters and downspouts thoroughly to ensure that water can flow freely away from your roof and foundation.

3. Trim Overhanging Branches

Trim any overhanging branches that could potentially fall onto your roof during a winter storm. Heavy snow and ice can weigh down branches, causing them to break and damage your roof.

4. Check Your Attic Insulation and Ventilation

Proper attic insulation and ventilation are crucial for preventing ice dams and roof leaks. Ensure that your attic is properly insulated to keep warm air from escaping and melting snow on your roof. Also, check that your attic is well-ventilated to allow excess heat and moisture to escape.

5. Install Roof Heating Cables

If you’re prone to ice dams on your roof, consider installing roof heating cables. These cables can help prevent ice dams from forming by melting snow and ice along the edges of your roof.

6. Seal Leaks and Cracks

Inspect your roof for any leaks or cracks and seal them with roofing cement or silicone caulk. Pay close attention to areas around chimneys, vents, and skylights, as these are common areas for leaks to occur.

7. Clear Snow from Your Roof

After a heavy snowfall, use a roof rake to remove snow from your roof. Clearing snow can help prevent ice dams from forming and reduce the risk of roof collapse due to the weight of snow and ice.

8. Maintain Your Roof

Regular roof maintenance is key to preventing damage and prolonging the life of your roof. Schedule regular inspections and maintenance with a professional roofing contractor to ensure that your roof is in good condition.

9. Consider a Roof Replacement

If your roof is old or in poor condition, consider replacing it before winter arrives. A new roof can provide better insulation and protection against the elements, reducing the risk of leaks and damage.

10. Prepare for Emergency Repairs

Despite your best efforts, winter weather can still cause damage to your roof. Be prepared for emergency repairs by having a supply of roofing materials on hand and knowing how to safely access your roof in case of a leak or other damage.


Preparing your roof for Calgary’s winter is essential for protecting your home and ensuring your family’s safety and comfort. By following these tips, you can help prevent damage to your roof and enjoy a warm and dry home throughout the winter months.

What should you inspect on your roof before winter?

Before winter arrives, it’s essential to inspect several key areas of your roof to ensure it’s ready to withstand Calgary’s harsh weather:

  1. Shingles: Check for missing, cracked, or damaged shingles. Damaged shingles can allow water to penetrate your roof, leading to leaks and water damage.
  2. Flashing: Inspect the flashing around chimneys, skylights, and vents. Damaged flashing can also cause leaks, so make sure it’s secure and in good condition.
  3. Gutters and Downspouts: Clean out any debris from gutters and downspouts to ensure proper drainage. Clogged gutters can lead to water backup and ice dams, which can damage your roof.
  4. Attic: Check the attic for signs of water stains, mold, or mildew. These could indicate roof leaks or poor ventilation, both of which need to be addressed before winter.
  5. Insulation: Ensure that your attic insulation is sufficient and evenly distributed. Proper insulation helps prevent heat loss, which can contribute to ice dam formation on the roof.
  6. Ventilation: Check attic vents to ensure they are clear of debris and functioning properly. Proper ventilation helps regulate temperature and moisture levels in the attic, reducing the risk of ice dams.
  7. Roof Structure: Inspect the overall structure of your roof for any sagging or signs of damage. Addressing structural issues before winter prevents further damage from heavy snow accumulation.

By conducting a thorough inspection of these areas before winter. You can identify and address any potential issues. This proactive approach helps protect your roof from damage and ensures your home stays warm and dry throughout the winter months.

“Preparing your roof for Calgary’s harsh winters is crucial for safeguarding your home from potential damage. From inspecting shingles and clearing gutters to ensuring proper insulation and emergency preparedness, these steps ensure your roof remains resilient against heavy snowfall and freezing temperatures, keeping your home warm and dry throughout the winter months.”

How can you prevent ice dams on your roof?

Preventing ice dams on your roof involves several key steps:

  1. Proper Insulation: Ensure your attic is well-insulated to prevent heat from escaping and warming the roof. It can melt snow and contribute to ice dam formation.
  2. Ventilation: Maintain good attic ventilation to keep the attic temperature close to the outside temperature. This helps prevent snow from melting on the roof due to excess heat buildup.
  3. Seal Air Leaks: Seal gaps and cracks in the attic floor, walls, and around penetrations (like pipes and vents) to prevent warm air from rising into the attic space.
  4. Clear Gutters and Downspouts: Keep gutters and downspouts clear of debris to allow proper drainage of melting snow. Clogged gutters can contribute to ice dam formation.
  5. Install Roof Heating Cables: Consider installing roof heating cables along the eaves of the roof to melt snow and prevent ice dams from forming.
  6. Use a Roof Rake: After heavy snowfall, use a roof rake to safely remove snow from the lower portion of the roof to prevent it from melting and refreezing at the eaves.

By taking these preventive measures, you can reduce the risk of ice dams forming on your roof during Calgary’s winter. Protecting your home from potential water damage and roof leaks.

How can you prepare for emergency roof repairs?
