An emergency roof repair is work needed right away to stop active water entry or a safety risk, such as an ice dam leak, storm damage or a dangerous snow load. In Montreal it usually costs more than a comparable daytime repair; small repairs often run a few hundred dollars up to about $2,000 before taxes, with winter and after-hours calls costing more.
Roof emergencies rarely happen on a sunny Tuesday afternoon. They happen at 11 p.m. in January, when water starts dripping from a light fixture or a chunk of ice tears off the gutter. In Montreal, winter is when most homeowners discover what an emergency roof repair really involves.
Here is how to tell a true emergency from a problem that can wait a few days, what a roofer can actually do in the cold, and how the cost usually compares to regular work.
What counts as an emergency roof repair
An emergency roof repair is work that cannot wait without causing more damage or creating a safety risk. In practice, that usually means:
- Water actively coming into the house, especially near electrical fixtures
- A section of roof torn open by wind or a fallen tree
- Ice dams forcing water under the shingles and into walls or ceilings
- A heavy snow load causing sagging, cracking sounds or doors that suddenly stick
- Broken flashing around a chimney letting water pour in during a storm
On the other hand, a few missing shingles with no leak, a small stain that is not growing, or a gutter that is loose but not falling can usually wait for a regular appointment. That alone can save you money.
Winter emergencies in Montreal
Montreal winters bring their own type of roof trouble. Freeze-thaw cycles, heavy snowfalls and long cold spells all put stress on roofs, especially older ones.
Ice dams
Ice dams form when heat from the house melts snow on the roof, the water runs down and refreezes at the colder edge. The ridge of ice traps more water behind it, which can back up under shingles. Say you own a 1950s bungalow in Ahuntsic with limited attic insulation: that is a classic setup for ice dams along the eaves.
In an emergency, a roofer may remove part of the ice dam or create channels to let water drain. The long-term fix usually involves insulation and ventilation in the attic, which is a separate conversation.
Snow load
Flat roofs on duplexes and triplexes, common in Rosemont, Villeray and the Plateau, can accumulate heavy, wet snow. If you notice sagging, cracking sounds or new cracks in interior walls, treat it seriously and call a professional. Clearing snow from a roof is dangerous work; do not go up yourself.
Tarping
When a roof is damaged and a permanent repair is not possible in the cold, tarping is the standard temporary fix. A crew secures a heavy tarp over the damaged area to keep water and snow out until weather allows a proper repair. It is meant to buy time, not to last for months.
How much emergency roof repair costs
Emergency work costs more than the same job booked in advance. The crew drops other work, may come in the evening or on a weekend, and has to work safely on a cold, slippery surface.
| Situation | Rough cost before taxes |
|---|---|
| Small repair booked in normal conditions | Often a few hundred dollars up to about $2,000 |
| Same type of repair as an emergency, in winter or after hours | More than the regular price |
| Temporary tarping, followed by a permanent repair later | Two visits, so two charges to expect |
| Damage too widespread to repair | Replacement, often around $6 to $12 per sq ft for asphalt shingles |
The final price varies with size, slope, access and condition. GST and QST (14.975% total) are usually added on top.
Even in an emergency, ask for a written price before work starts, or at least a clear written description of how the visit will be billed. And when the permanent repair comes up, comparing quotes from several licensed contractors is still the best protection, even if the first emergency visit was with whoever could come fastest.
What to do while you wait for the roofer
You can limit the damage safely from inside the house:
- Move furniture, electronics and valuables away from the leak.
- Place buckets or containers under drips and protect the floor.
- If water is near light fixtures or outlets, turn off power to that area at the panel if you can do it safely.
- If a ceiling is bulging with water, keep people away from underneath.
- Take photos and videos of the damage for your insurer.
- Call your insurer to report the situation and ask about next steps.
Never climb on a wet, icy, snowy or steep roof. Most serious roof injuries happen exactly in these conditions.
Will insurance cover an emergency roof repair?
Home insurance usually covers sudden and accidental damage, such as storm, wind or a fallen tree. It generally does not cover wear and tear or lack of maintenance. Ice dam damage can fall in a grey zone depending on your policy and the cause, so read your wording or call your insurer.
Deductibles apply. Many insurers also expect you to take reasonable steps to prevent further damage, which is one reason emergency tarping makes sense. Keep every invoice and photo.
Hiring a roofer in an emergency
Emergencies are when people make rushed decisions. Even under pressure, check that the contractor holds a valid licence from the Régie du bâtiment du Québec (RBQ) with the right subclass, avoid large cash payments and get a written description of the work. Be cautious with anyone who knocks on your door right after a storm.
Bottom line
An emergency roof repair is about stopping water and keeping people safe, not about a perfect fix at midnight. Expect to pay more than for regular work, especially in winter or after hours, and plan for a temporary repair followed by a permanent one. Document everything, call your insurer, verify the RBQ licence and get written, detailed quotes for the final repair. Coverage and practices vary by insurer and situation, so ask questions before you sign.

Can a roof be repaired in winter in Montreal?
Some repairs can be done in winter, but cold and snow limit what materials can be installed properly. Often a roofer will make a temporary repair or tarp the area and return for the permanent fix when weather allows.
Should I remove snow from my roof myself?
No. Climbing on a snowy or icy roof is dangerous, and aggressive scraping can damage shingles or membranes. Call a professional if you are worried about snow load.
Is ice dam damage covered by home insurance?
It depends on your policy and the cause of the damage. Sudden water damage may be covered while issues linked to lack of maintenance may not, so check your wording with your insurer.
