After a big storm followed by freezing rain, many homeowners look up at their roof and wonder whether they should do something. Roof snow removal in Brossard isn’t needed after every snowfall, but it becomes necessary when snow and ice pile up, when signs of overload appear or when icicles threaten people below. Here’s how to assess the situation and get the job done safely.
This guide covers the roof only. For your driveway, see our page on snow removal contracts in Brossard.
Why roof snow removal matters
Roofs are built to carry a snow load, but the actual weight varies a lot with the weather. Fresh, fluffy snow is light; wet, packed or rain-soaked snow is much heavier, and ice is heavier still. On the South Shore, midwinter thaws and rain are common, and that’s often when the risk rises.
The Régie du bâtiment du Québec (RBQ) reminds owners that each one is responsible for the safety of the people who live in or visit their building. That means keeping an eye on snow and ice build-up and removing ice and icicles along the roof edge, which endanger pedestrians and cars.
When to clear your roof: warning signs
According to the RBQ, these signs point to a possible overload. If you notice one, have the roof cleared regardless of how much snow you see:
- cracks in interior walls;
- interior doors that jam or rub against the frame;
- unusual creaking sounds;
- a ceiling that starts to sag.
Also check after several storms in a row (especially with rain), when wind creates drifts against a higher wall or parapet, when large icicles hang over a door or sidewalk, or when water stains appear on a ceiling. Flat roofs on plexes, condos and commercial buildings need extra attention because snow doesn’t slide off.
Working at heights: what the CNESST says
The CNESST lists the main dangers: falling off the roof and being buried in snow, large snow slabs suddenly sliding (especially on smooth metal roofing), and temporary shelters collapsing on someone pushing snow from inside. As of its prevention page consulted on November 2, 2026, workers must be protected against falls whenever they are exposed to a fall of more than 3 m.
| Roof type | Practices recommended by the CNESST |
|---|---|
| Sloped roof | Start from the ground with a telescopic roof rake, often enough for a house; if someone goes up, work from the top down with fall protection. |
| Flat roof | Plan the job, restrict access to the drop zone, install guardrails and a warning line, leave an uncleared strip along the edge. |
| Temporary shelter | Clear with a roof rake only, never from inside. |
| Ladder access | Ladder set firmly on the ground, secured at the roof edge and extending above it. |
When guardrails aren’t possible, the CNESST calls for a harness with an energy absorber, tied to an anchor of adequate strength.
Hiring an insured professional
The RBQ recommends specialized companies, which have the equipment and methods to avoid damaging the roof membrane. Before hiring:
- ask for proof of current liability insurance;
- check that the company is registered with the CNESST for its workers;
- ask how its crew is protected against falls;
- get a written quote: area covered, method, handling of snow on the ground, response time;
- ask them to leave a thin layer of snow to protect the roofing;
- set up a safety perimeter on the ground during the work.
To compare companies, send a request through our quotes page or estimations.pro. If the roof is already damaged, a roofer in Brossard can inspect it in the spring.
Ice and ice dams
An ice dam forms when heat from the house melts snow on the roof. The water runs to the colder edge and freezes there, blocking drainage, so meltwater can seep under the shingles and stain ceilings.
- Short term: have dangerous icicles removed by a pro. Don’t hack at ice with a hammer: you’ll damage shingles and gutters.
- Long term: the cause is often in the attic, with poor insulation or ventilation. A roofer or insulation contractor can find it.
Maintenance tips
- Clean gutters and downspouts in the fall.
- Have the roof and flashing inspected before winter.
- Keep a roof rake handy for small build-ups you can reach from the ground.
- Always clear emergency exits, balconies, sheds and garages.

FAQ
Should I clear my roof after every storm?
No. A roof in good condition usually handles the snow. Act when you see overload signs, unusual heavy snow or ice, or dangerous icicles.
Can I do it myself?
From the ground with a roof rake, often yes for a house. Climbing onto the roof without fall protection is dangerous; the CNESST and RBQ recommend equipped specialists.
Who is responsible for falling icicles?
According to the RBQ, the owner is responsible for the safety of people around the building and must remove ice and icicles along the roof edge.
How do I prevent ice dams?
Reduce heat loss to the roof through attic insulation and ventilation, and keep gutters clear.
