Can Your Roof Be Repaired in Winter? Yes — And Here’s How

Professional roofing companies in Ontario regularly repair roofs throughout the winter season. While some roofing materials become more rigid in freezing temperatures, experienced roofers know how to work with them safely.

At All Stars Roofing Inc, winter roofing is common because:

• Emergencies won’t wait for spring

• Small problems worsen in freezing conditions

• Insurance claims often require immediate action

• Ice dams can cause major interior damage
  

The key is hiring a roofing company familiar with cold-weather installation standards, the Ontario Building Code, and winter safety practices.

What Roof Repairs Can Be Done in Winter?

Here are the roofing issues that can be repaired safely and effectively in cold weather:

1. Emergency Roof Leak Repairs

If your roof is leaking, you must address it immediately. Winter leaks can spread rapidly due to melting snow and fluctuating temperatures. Professionals can:

• Patch the leak

• Install temporary protection

• Replace damaged shingles

• Seal exposed areas
  

2. Shingle Replacement

Asphalt shingles can become slightly brittle in cold temperatures, but with the right tools and methods, spot repairs are still completely safe.

Roofers typically:

• Use warming boxes for shingles

• Increase hand-nailing accuracy

• Apply specialized cold-weather adhesives
  

3. Ice Dam Removal

Ice dams are extremely common in Ontario winters. Roofers can:

• Steam-remove ice dams (safe method)

• Repair damaged shingles

• Install underlayment

• Improve ventilation
  

4. Flashing & Vent Repairs

Chimney flashing, roof vents, pipe boots, and skylight flashing often fail in winter. These repairs are straightforward and unaffected by cold weather.

5. Minor Structural Repairs

If cold temperatures haven’t compromised the roof’s structure, professionals can fix:

• Fascia damage

• Soffit issues

• Eave rot

• Minor decking repairs

What Roofing Repairs Cannot Be Done in Winter?

Some jobs are possible but not ideal when temperatures drop below -10°C.

Full Roof Replacements

While many contractors can perform full roof installations in winter, the very best practice is to do replacements when:

• The temperature is above freezing

• Adhesives can fully bond

• Shingles are flexible
  

However, if the roof is severely damaged or unsafe, replacement in winter is absolutely possible using winter-rated techniques.

Challenges of Winter Roof Repairs (And How Professionals Handle Them)

Winter repairs require skill and experience. Here are the main challenges and how trained roofers overcome them:

1. Cold Weather Adhesion

Asphalt shingles need a certain temperature for the self-seal strip to activate naturally. Solution: Roofers apply cold-weather roofing adhesives and use hand-nailing for a secure seal.

2. Slippery Surfaces

Snow and ice increase the risk of slipping.

Solution: Professionals use:

• Safety harnesses

• Roof shoes with enhanced grip

• Snow removal and surface prep before work
  

3. Brittle Shingles

In extreme cold, shingles can crack under pressure.

Solution: Roofers warm the shingles before installation and handle them carefully.

4. Shorter Work Windows

Winter daylight hours are limited.

Solution: Winter crews plan tight schedules and prioritize emergency calls.

Is Winter a Good Time to Repair a Roof?

Winter can actually be the best time to fix certain roofing problems.

Here’s why:

Damage Is More Visible

Melting snow reveals leaks instantly.

Issues Get Worse in Winter

Small cracks become large leaks due to freezing and thawing cycles.

Faster Response Times

Roofing companies are often busiest in the spring and fall.

Emergency Work Is Priority

Your home won’t be left vulnerable because contractors prioritize winter hazards.

Signs You Need a Winter Roof Repair

If you notice any of these, call a roofing expert immediately:

• Water stains on ceilings or walls

• Dripping water

• Ice dams along the edges of the roof

• Missing or curling shingles

• Cold drafts

• Sagging areas on the roof

• Mold or mildew smell in the attic
  

Winter is not a time to wait — roofing problems spread quickly.

Should You Wait Until Spring to Repair a Roof?

Only if the problem is purely cosmetic.

If the issue threatens your home, it must be repaired right away. Waiting until spring can lead to:

• Mold growth

• Structural damage

• Interior water damage

• Higher repair costs

• Insurance complications

A professional roofer will tell you whether the issue needs immediate repair or can safely wait.
