Winter’s here, the snow’s piling up, and you’re wondering what to do with your gutters until spring. Good news: you don’t have to ignore them completely or climb onto your icy roof.
This guide tells you exactly how to keep an eye on your eavestroughs during the Quebec winter, what signs call for prompt intervention, and above all what mistakes to avoid. You’ll know when to do it yourself and when to call a professional – without unnecessary panic.
Things to remember
- Gutter maintenance in winter is mainly limited to monitoring from the ground
- Ice dams are the main hazard to watch out for
- Never climb onto an icy roof – it’s an absolute rule
- Some signs require an emergency call, others can wait until spring.
Understanding ice dams
Ice dams are the main threat to your plastic or aluminum eavestroughs during the Quebec winter. They form when the warmth of the house melts the snow on the roof, and the water refreezes as it reaches the colder eavestroughs.
Signs of a problematic ice dam :
- Thick, wide ice cubes rather than thin ones
- Ice accumulating on several rows of shingles
- Water visible behind the ice on mild days
The permanent solution is better attic insulation and ventilation – a project for the spring. In the meantime, monitoring remains your best tool.
For a better understanding of this phenomenon, consult CAA-Quebec’s guide to ice dams.

Inspections during the Québec winter
Visual inspection from the ground (every 2-3 weeks)
There’s no need to climb. Just walk around your house after every warm spell or major snow accumulation. Observe:
- Excessive icicles along gutters (over 30 cm = alarm signal)
- Visible collapse of a section under the weight of ice
- Ice build-up spills over fascias
- New water stains on exterior walls or soffits
Internal inspection (monthly)
Inspect the interior of your home, especially :
- Ceilings under the roof (stains, blisters, mold)
- Walls near the eaves
- The attic, if you have access to it (humidity, abnormal frost)
These interior signs often reveal gutter problems before they become visible on the outside.
When to call in a professional
Some situations can’t wait for spring. Contact a professional immediately if you observe :
- Active water infiltration in the house (leaky ceiling, wet wall)
- Massive ice dam with visible water rising under the shingles
- Gutter torn off or about to fall off
- Ice accumulation that threatens an entrance, balcony or pedestrian walkway
- Significant deformation of fascia or soffit
Don’t try to solve these problems yourself in winter. Our professionals have the equipment and experience to work safely on icy roofs.

What never to do in Quebec winter
Dangerous mistakes to avoid
- Climbing on roofs or ladders on icy surfaces – risk of serious fall
- Break the ice in the gutters with a hammer or shovel – you’ll damage the metal and the shingles.
- Use de-icing salt in gutters – accelerated corrosion and foundation damage
- Pull on the ice cubes to unhook them – they can carry away the gutter or injure you.
- Using a direct heat source (torch, industrial dryer) – risk of fire and damage
Less serious but costly errors
- Ignore the little ice cubes that become big problems
- Wait until infiltration is major before taking action
- Neglecting interior home inspections
- Shoveling snow from the roof without training or proper equipment
What to do depending on the situation
Observed situation | Emergency level | Recommended action |
Small ice cubes (less than 15 cm) | Normal | Regular monitoring |
Medium icicles (15-30 cm), no infiltration | Attention | Keep a close eye on us, note our progress |
Large icicles (over 30 cm), visible ice dam | Of concern | Consult a professional quickly |
Active water infiltration indoors | Emergency | |
Collapsed or torn eaves | Emergency | Call us immediately |
Ice threatening a passageway or entrance | Safety emergency | Call us immediately |
What you can safely do yourself
From the ground only:
- Clear accumulated snow from the base of downspouts
- Make sure meltwater runs away from the foundation
- Document problems with photos (useful for insurance and repairs)
- Keep downspout outlets clear during mild weather
Inside:
- Improve attic ventilation if possible (open air vents)
- Place containers under minor infiltrations while awaiting intervention
- Report any problems to your insurer as soon as possible if the damage is significant.

What to plan now for spring?
Take advantage of winter to draw up a list of work to be done as soon as the thaw sets in. Make a note of gutter sections to be repaired, slope problems to be corrected and the state of your attic insulation. Now’s the time to consider installing heating cables or gutter guards to prevent future problems.
Complete gutter maintenance in spring and autumn, every year, will correct any weaknesses revealed by winter.
Winter with peace of mind
Maintaining eavestroughs during the Quebec winter doesn’t require any acrobatic feats. Regular monitoring from the ground, watching out for signs of water infiltration, and the wisdom not to intervene yourself on an icy roof, especially at high elevations – that’s the recipe for avoiding unpleasant surprises.
Make a note of what you observe, act quickly in the event of a real emergency, and plan your patches for the spring.

FAQ
Do I have to remove dead leaves and snow from my gutters in winter?
No. Leave the snow alone – it often acts as insulation. Removing snow from eavestroughs without proper equipment may cause more damage than it prevents.
Are heating cables effective?
Yes, when properly installed. They prevent ice dams in problem areas. However, for a professional advice submission, they treat the symptom – attic insulation remains the lasting solution.
Does my insurance cover damage caused by frozen eavestroughs?
Generally yes, for sudden damage such as seepage. Consult your policy and document any problems with dated photos. Normal wear and tear is not usually covered.
At what temperature do ice dams form?
They appear during freeze-thaw cycles, often when it’s between -5°C and 0°C outside. Many companies recommend a well-insulated roof to prevent this phenomenon from accelerating even in colder weather.
Can I install gutter guards in winter?
No, wait until spring. Installation requires dry conditions and above-zero temperatures to ensure a secure, long-lasting bond.
