The Alberta winter eavestrough checklist
Freeze-up in the Edmonton region usually lands somewhere between the last week of October and mid-November. Everything on this list needs to be done before that — once the trough freezes, it's frozen until spring. Most of it takes an afternoon.
1. Clear the troughs completely
Not just the leaves on top — the wet silt at the bottom too. That layer is what freezes into a solid block and gives ice dams a base to build on.
2. Flush and flow-test every downspout
Run a hose into the top of each downspout and confirm water comes out the bottom at full flow. A weak trickle means an elbow blockage. This is the single most-skipped step and the most common cause of spring basement seepage.
3. Extend downspout discharge away from the foundation
Six feet minimum, sloped away from the house, discharging onto grass or gravel — not onto a walkway where it becomes an ice sheet, and not onto your neighbour's lot.
4. Check trough pitch
Water should move toward the outlet, not pool. Standing water in a level run freezes first and pulls the trough down under the weight. A short section can usually be re-pitched by adjusting hangers.
5. Re-secure loose hangers and check the fascia
Any gap between the trough and the fascia board means water is running behind it. Soft or dark fascia wood needs attention before winter loading makes it worse.
6. Seal pinhole leaks and open seams
Small leaks drip, freeze and grow ice columns down the wall all winter. Gutter sealant needs above-freezing temperatures to cure, so this has to happen in October, not December.
7. Clear the roof surface and valleys
Leaves and needles left in valleys, behind chimneys and around vents hold moisture on shingles and refill your clean troughs with the first rain. Blow the roof clear at the same time as the trough clean.
8. Look at the attic while you're at it
Frost on the underside of the roof deck, compressed insulation, or a bath fan venting into the attic space are all early warnings of the heat loss that drives ice dams. Cheap to fix in fall, expensive in February.
9. Confirm sump discharge and window wells
Sump lines that discharge next to the foundation freeze and back up. Window wells full of leaves fill with meltwater. Both are ten-minute checks.
10. Take photos
Photograph each elevation once the work is done. Next fall you'll be able to compare and see exactly what changed — and if you ever make an insurance claim for water damage, documented maintenance matters.
Common questions
When is the deadline for fall eavestrough cleaning in Edmonton?
Late October. Aim for the last two weeks — leaves are down, and troughs aren't frozen yet.
Can eavestroughs be cleaned in winter?
Only during a genuine thaw, and it's limited. Frozen debris can't be removed without damaging the trough.
Should I remove downspout extensions for winter?
No — leave them on and sloped away. Removing them is how meltwater ends up at the foundation.
Do you do this whole checklist as a service?
Items 1 through 7 are covered in our standard clean plus roof debris add-on, and you get the photo report from item 10 either way.
