Roof Snow Removal in Toronto & the GTA

After a lake-effect dump buries the GTA, the question arrives on schedule: how much snow can a roof hold? More than most people fear — a properly built pitched roof shrugs off a normal Ontario winter. The genuine concerns are flat roofs, low-slope additions, drift zones where wind piles one area deep, and heavy wet snow sitting on structures that were marginal to begin with.

Method matters, because a shovel can do more damage than the snow. We clear with poly shovels and roof rakes and leave a thin layer on the shingles — scraping to bare asphalt in the cold tears off granules and edges. On flat roofs the drains and scuppers get opened first; removing snow while the drain is an ice plug just builds a skating rink. Timing beats heroics, too: clearing before a thaw-freeze swing prevents both the load and the ice.

Honesty first: most sloped GTA roofs never need clearing, and if yours doesn't, we'll say so rather than sell you a visit. Where snow removal from the roof earns its keep is real snow load on low-slope structures, drifts against a second storey, and eaves that feed ice dams — taking the snow away removes the raw material before the melt-refreeze cycle can get to work on it.

What this covers

  • Pitched-roof clearing with poly shovels and roof rakes, leaving a protective layer so shingles aren't scraped bare
  • Flat roof snow removal with drains and scuppers opened first so meltwater can actually leave
  • Drift removal where wind has loaded one slope or piled snow against a wall
  • Eaves cleared back to starve ice dam formation
  • Skylights, plumbing stacks and furnace exhausts dug out — a snow-blocked vent is a carbon monoxide risk
  • Ground protection for the drop zone, and cleanup of walkways, meters and shrubs afterwards
  • A quick condition report on anything spotted while up there — lifted shingles, ice at the eaves

What affects the price

  • Snow depth and density — saturated March snow weighs several times what a fluffy January fall does
  • Roof size, pitch and height
  • Flat versus sloped, since flat roofs are hand work with drainage to manage
  • Access and drop zones: decks, cars, glass and gas meters below all slow the drop
  • Urgency — post-storm emergency clearing books differently than a scheduled visit
  • One-time clear versus a standing arrangement for heavy-snow winters

Common questions

How much snow on a roof is too much?
Depth alone misleads — 30 centimetres of dry powder is a modest load, while the same depth soaked by rain can triple it. Sloped roofs built to code carry Ontario's design snow load with margin. The red flags are performance, not centimetres: interior doors suddenly sticking, cracking or popping sounds, or a visible sag in a ceiling or roofline mean clear it now.
Should I clear the roof after every snowfall?
For most sloped roofs, no — routine clearing adds wear and risk for little benefit, and the roof was engineered for the weather it lives in. Clearing makes sense after exceptional accumulations, when rain is forecast onto a deep snowpack, on low-slope and flat sections, and where drifting loads one area far beyond the rest of the roof.
Can I use a roof rake myself?
Yes — from the ground, and it's genuinely worthwhile. Pulling the first metre or so of snow off above the eaves after each big storm removes the fuel that ice dams burn, and you never leave the driveway. What we'd steer you away from is ladders on ice, climbing onto a snowy roof, or metal tools that gouge frozen shingles.
Does removing snow prevent ice dams?
It helps by removing the raw material. Ice dams form when attic heat melts the snowpack from below and the water refreezes at the cold eaves, backing up under the shingles — no snow, no melt. But it's management, not a cure: the permanent fix is air sealing, insulation and ventilation in the attic, with clearing as the stopgap in heavy winters.
Will shovelling damage my shingles?
Done wrong, absolutely — cold shingles are brittle, and scraping to the surface with a metal blade takes granules, edges and occasionally whole tabs. Done right, no: poly tools only, working with the slope, and a few centimetres of snow deliberately left behind as a cushion. If someone quotes you a broom-clean bare roof in February, that's a warning sign, not a selling point.
