Flat Roof Snow Removal in Montreal

Montreal is a city of flat roofs: duplexes, triplexes, walk-ups and greystones, often with a parapet that traps drifting snow. Flat roof snow removal in Montreal matters because nothing slides off: every storm adds weight, and a buried roof drain turns the next thaw into a pond sitting on the membrane. Roof Snow Bros clears flat roofs across the island and in Laval, working by hand so the membrane comes through the winter undamaged.

Our Process

  1. Roof check: we measure the snow, look for drifts along parapets and walls, and locate drains, scuppers, vents and skylights before anyone starts shovelling.
  2. Safe access and anchoring: crews tie off with fall-arrest harnesses; on plexes we plan how the snow goes down to the lane or yard without blocking exterior staircases.
  3. Layer-by-layer clearing: plastic shovels only, leaving 5 to 10 cm over the membrane, starting with the heaviest drifts.
  4. Drains open: roof drains and scuppers are cleared and any ice around them is melted with low-pressure steam.
  5. Clean finish: snow is cleared off balconies and staircases it lands on, and away from entrances.

Flat Roofs We Clear

  • Elastomeric (two-ply torch-on) membranes on duplexes and triplexes
  • Tar-and-gravel roofs with ballast
  • TPO and EPDM membranes on newer additions and low-rise condos
  • Walk-ups, mixed-use buildings and flat-roof garages

Signs Your Flat Roof Needs Clearing Now

  • Snow is level with or drifting over the top of the parapet
  • The roof drain or scupper is buried and water pools after a mild day
  • Interior doors on the top floor stick or no longer latch
  • New cracks appear in plaster or drywall near the top-floor ceilings
  • You hear creaking or cracking from the roof during or after a storm
  • A sewer smell inside the unit, usually a plumbing vent buried under snow

Frequently Asked Questions

Most flat-roof duplexes, triplexes and walk-ups cost $400 to $900 per visit. Parapet height, drifting, ice around the drains and how we get the snow down to the lane all affect the final price.
Flat roofs hold everything that falls on them, so load builds fast. Call at about 30 cm (12 in) of wet snow or 60 to 70 cm (24 to 28 in) of dry snow, or sooner if drifts are piling against the parapet or the roof drain is buried and water is pooling.
We do not, and we advise against it. A snowblower's auger and skid shoes tear elastomeric and TPO membranes, throw gravel ballast off the roof and can hit vents, and there is no margin for error near a parapet. We clear flat roofs by hand in layers, which protects the membrane.
No. Our shovels are plastic, we never chip ice off the membrane, and we leave a 5 to 10 cm (2 to 4 in) layer of snow over the surface. Ice around drains is melted with low-pressure steam.
In Quebec the owner is responsible for keeping the roof safe for tenants. Landlords of plexes often choose a seasonal contract so the roof is cleared automatically each time accumulation passes an agreed threshold, typically 30 to 40 cm.
