Winter Roof Replacement in Calgary

A popular question we get asked as the fall weather settles in is “Can I Replace my Roof in the Winter?” and we reply with a confident “Yes!”.

It’s a common misconception that roof replacements are seasonal, especially in Southern Alberta.  Many homeowners are in a rush to have their roofs replaced in the spring & fall but don’t realize that their roof can be replaced in the winter.

Winter roof replacements may take a bit longer as special care will be taken to ensure proper application and a safe work site, but the wait time for the work to begin will likely be shorter than in the warmer months.

Our warranty at Hubbard Roofing & Exteriors will remain the same no matter what month you replace your roof, which is our guarantee that we will provide the best workmanship and only work in conditions that support that.  Request a free quote today to get started.

Before any work will be completed the snow will be removed from the roof (if applicable) and the crew will ensure the roof is safe to walk on.  Safety harnesses and ropes will be worn by everyone who requires it (by Occupational Health & Safety standards), which is mandatory year-round.

According to a GAF Technical Advisory Bulletin, there is no upper or lower temperature limit governing when asphalt shingles may be applied, if appropriate precautions are taken.

It may seem like Calgary & Southern Alberta are in a deep freeze all winter long but according to, the temperatures in the chart below might surprise you.  The sunny winter days and chinook conditions work in our favour for installation and a mild, sunny day is all it takes to seal the shingle adhesive.

Winter application precautions include:

  • Use extra care when handling shingles to ensure they do not crack
  • Adjust nail guns accordingly (this is normal practice in the summer as well)
  • Hand-seal shingles when needed (this is not required often due to the number of sunny days we experience)

We will not perform work in temperatures that will put the material at risk or compromise the safety of our crews.


We inspect every roof we replace to ensure it meets our high standards and double check that no roofing material was left behind.  If a snow filled yard prevents us from completing a thorough ground check, we will schedule a day to return in the spring to ensure no debris was unaccounted for.

Winter roof replacements are a great option for homeowners in Calgary & surrounding areas.  Our crews often prefer a cooler day to a hotter one; which comes with its own set of application precautions.
