Your roof is your home’s first line of defense, and Canadian weather puts it to the test every single season. From freezing winters to hot, humid summers, the environment plays a major role in how well your roof holds up.

Knowing how weather affects your roof can help you stay ahead of damage, avoid expensive repairs, and extend the life of your roofing system.

Let’s break it down season by season.

1. Winter: Snow, Ice, and Freeze-Thaw Damage

Canadian winters are harsh. Snow piles up, temperatures drop, and the freeze-thaw cycle starts causing trouble.

Common winter-related roofing issues include:

• Ice dams that trap water under shingles

• Snow buildup that adds heavy weight and causes sagging

• Frozen gutters that block water flow

• Cracked shingles from repeated freezing and thawing

Prevention tip: Insulate your attic properly and keep ventilation balanced to avoid uneven roof temperatures.

2. Spring: Melting, Rain, and Hidden Damage

As snow melts and rain returns, spring can expose the damage winter left behind. Water starts moving again, and leaks often appear.

Watch for:

• New water stains inside your home

• Soft or sagging spots on the roof

• Clogged gutters or downspouts

• Flashing that has shifted or pulled away

Spring inspections are essential to catch small problems before they grow.

3. Summer: UV Exposure and Heat Stress

Hot summer temperatures and strong sunlight break down roofing materials over time. Even the best shingles will age faster if constantly exposed to direct UV rays.

Risks include:

• Shingle curling, cracking, or fading

• Accelerated aging of underlayment and adhesives

• Heat buildup in the attic causing ventilation problems

Solution: Choose UV-resistant shingles and maintain attic airflow to reduce heat buildup.

4. Fall: Wind, Debris, and Gutter Clogs

Fall winds can be strong in many parts of Canada, especially during early storms. Combined with falling leaves and debris, this season brings its own set of roofing challenges.

Look out for:

• Loose or missing shingles

• Branches rubbing against the roof

• Overflowing or clogged gutters

• Vent covers or flashing being pulled loose

Tip: Do a quick cleanup before winter sets in. This is the ideal time for pre-winter maintenance.
