The winter moment everyone dreads
You look up and see icicles. Big ones. Then you notice water staining on the brick, siding, or around the soffit.
Joshua – a North York, Toronto homeowners describe it: the eavestrough freezes, ice builds at the roof edge, and water ends up travelling where it should not.
Why ice dams happen
The heat escapes, snow melts, then refreezes at the colder roof edge and inside the eavestrough and downspout. Property construction conversations and homeowner threads repeatedly point to insulation and ventilation as root causes.
Why Toronto homes get hit hard
- Many Toronto semis have rooflines that dump a lot of meltwater into a limited number of downspouts.
- Freeze thaw cycles are common.
- Leaf debris left behind in late fall traps water, which freezes into a plug.
What to do right now
- Keep ground areas clear where downspouts discharge so meltwater can flow.
- If a downspout is frozen, avoid hammering it. Cracks are common when ice expands and the metal flexes.
- If you have active interior leaking, call a pro. This can become a roof and insulation problem fast.
Long term solutions
Option #1: Pre-winter cleanout
The City of Toronto recommends cleaning eavestroughs at least twice a year and checking elbows and outlets for debris. That one step alone reduces the chance of freeze plugs.
Option #2: Improve attic insulation and ventilation
This addresses the cause, not the symptom. If your roof edge keeps refreezing meltwater, you will keep seeing ice.
Option #3: Heat cable in targeted areas
HomeStars includes heat cable as a cost item typically priced per linear foot (pricing varies widely).
Use this selectively, not as a substitute for fixing insulation and drainage.
Option #4: Replacement with correct pitch and flow
Replacement helps when:
- The eavestrough holds water due to poor pitch
- Outlets are undersized or poorly placed
- The system is deformed from past ice loads
Typical timelines
Clearing and thaw planning: same day to 1 day (depends on severity and access)
Insulation and ventilation improvements: 1 to 2 days for many homes
Eavestrough replacement: commonly 1 day for a standard home, longer for complex rooflines
Cost expectations
Labour and materials are commonly priced per linear foot. Toronto installs often land in a broad range depending on height and complexity, with common pricing references showing labour plus materials adding up quickly when multiple downspouts and corners are involved.

If your eavestrough freezes every winter, the goal is not to fight ice every February. The goal is to stop the conditions that create it.
