Ice Dams in Toronto: Why They’re Wrecking Roofs This Winter (And What Toronto Homeowners Should Do About It)

Toronto winters are no joke. One minute it’s snowing sideways, the next it’s a weird thaw, then back to -15°C. And right now, in February 2026, we’re seeing ice dams everywhere across the GTA. Those giant icicles hanging off roofs like frozen daggers? They’re not just Instagram-worthy. They’re a red flag that your roof could be in serious trouble.

If you’re dealing with water stains on ceilings, dripping in the attic, or those monster icicles that look ready to impale a snowman, you’ve probably got an ice dam problem. Ignoring it can turn a small issue into a five- or even fifteen-thousand-dollar roofing nightmare.

Let’s break it down casually (no jargon overload) so you know exactly what’s happening and why you should call pros like us at The HandyForce instead of grabbing a ladder and hoping for the best.

What Are Ice Dams (and Why Toronto Gets Hit Hard)?

Ice dams happen when heat from inside your house sneaks up into the attic and melts snow on the warmer upper part of your roof. The water runs down toward the eaves… but the eaves are super cold (they overhang away from the house heat). So the water refreezes into a thick ridge of ice that blocks everything like a frozen beaver dam.

More meltwater backs up behind it, finds tiny gaps under your shingles, and sneaks inside. Cue interior leaks, soggy insulation, mold, and rot.

Toronto’s weather makes this worse: heavy lake-effect snow, constant freeze-thaw cycles, and lots of older homes with so-so attic insulation and ventilation. Add in a record-breaking snow dump like the one we just had in late January 2026, and boom… ice dam city.

Signs You’re Dealing with Ice Dams Right Now

Step outside (safely, no hero ladder stunts), grab a coffee, and look up:

• Thick, long icicles along the roof edge or gutters (especially dirty-looking ones)
• Ice ridges or “waves” of ice building up in/around gutters
• Ice forming inside gutters (they’re not meant to be ice buckets)
• Water stains, bubbling paint, or drips on interior ceilings/walls
• Musty smells or damp spots in the attic
• Sagging gutters from the weight

If you spot any of these, don’t wait for spring. That water is already doing damage.

Why DIY Ice Dam Removal Is a Terrible Idea

We get it… you see the ice and think, “I’ll just chip it off.” Please don’t.

Hammering or chipping ice can crack shingles, pull gutters loose, or damage the roof membrane. You risk voiding your roof warranty, falling off the roof, or making the problem worse. We’ve seen homeowners turn a fixable issue into a full roof replacement.

The safe way pros remove ice dams is with steam. It melts the ice gently without bashing your roof. No ladders on ice, no broken tiles, no trip to emerge.

Long-Term Fixes: Stop Ice Dams from Coming Back Every Winter

Once the immediate danger is gone, the real fix is usually not your roof. It’s what’s happening in the attic:

• Boost attic insulation to keep heat in your living space (not escaping to melt snow)
• Improve ventilation so the attic stays closer to outdoor temps
• Seal air leaks around lights, hatches, and ducts
• Keep gutters clean so water drains freely when it does melt

These upgrades pay for themselves by preventing leaks, lowering energy bills, and extending your roof’s life.
