Eavestrough, Gutters & Downspouts
Eavestrough in
Canmore, Alberta.
Seamless aluminum sized and fastened for mountain snow rather than prairie rain. In Canmore the load coming off a roof is a different problem entirely.
Eavestrough in Canmore
What Canmore actually needs from a eavestrough job.
Canmore eavestrough deals with something prairie systems never face: sliding snow. A steep mountain roof carrying a deep load will release it, and anything hanging at the eave is in the path. That is why fastening, hanger spacing and the decision about where snow is allowed to come off matter more here than the gauge of the aluminum.
Volume is the second issue. Spring melt in the Bow Valley moves a great deal of water in a short window, and a five-inch run that is fine in Calgary can be genuinely undersized on a steep Canmore roof feeding two valleys. We size from the roof area draining to each outlet, and six-inch is a far more common recommendation here than on the prairie.
And then ice. A run that holds standing water through a mountain winter becomes a solid length of ice, and mountain ice loads are heavier than prairie ones. Correct pitch to the outlets and hidden hangers screwed into genuinely sound fascia are the whole job.
About Canmore
Canmore sits in the Bow Valley with forest on every side, which places almost the entire town inside what wildfire planners call the wildland-urban interface: there is little to no separation between the houses and the trees. Roughly 600 Canmore homes take part in the FireSmart program, the Bow Valley Community Fireguard runs along the edges of town, and since March 2018 the Land Use Bylaw has required a minimum Class B fire rating on all new and repaired roofs. Nowhere else in our service area does the roofing material itself carry that kind of regulatory weight.

Our Standard
What every Canmore eavestrough job includes.
Eavestrough is the least glamorous part of an exterior and the part with the most direct line to your foundation. We form seamless 5-inch and 6-inch aluminum on site, so a run has no joints along its length to work loose through a 60-degree annual temperature swing, hang it on hidden hangers screwed into solid fascia, and pitch it so water actually moves instead of standing and freezing.
Seamless, formed on site
Each run is rolled to length at your house, so the only joints are at corners and outlets. Sectional gutter has a seam every ten feet, and every seam is a future leak here.
5-inch and 6-inch K-style
Five-inch handles most homes. Six-inch is the right call for large roof areas, steep pitches that dump water fast, and homes under mature trees.
Correct pitch and sizing
Slope calculated to the outlets so water moves. Standing water is what freezes, and ice is what pulls a run off the fascia.
Hidden hangers into solid wood
Screwed hangers into sound fascia at proper spacing. If the fascia behind is rotten we tell you, because hanging new eavestrough on soft wood is money wasted.
Downspouts and discharge
Sized and placed to move volume, with extensions carrying water well clear of the foundation and away from the neighbouring property.
Gutter guards where they help
Worth it under mature trees and spruce. We will tell you honestly when your lot does not need them rather than adding a line to the quote.
Colour matched
A wide range of pre-finished aluminum colours matched to your fascia, trim and roof so the eaves read as one detail.
Done with the roof where it makes sense
If the roof is being replaced, doing the eavestrough at the same time costs less than a separate mobilisation later.
Canmore Pricing
What this costs in Canmore.
Real 2026 ranges for the Calgary region. Your written quote gives a firm number after we have been on site, because a price without an inspection is a guess.
5-inch seamless aluminum
$8 – $16 / linear ft
The standard for most homes
6-inch oversized
$10 – $18 / linear ft
Large roofs, steep pitch, heavy runoff
Bungalow, complete
$1,500 – $2,800
Roughly 140 – 180 linear feet
Two-storey, complete
$2,200 – $4,200
Roughly 180 – 240 linear feet
Downspouts run $100 to $250 each installed and gutter guards $6 to $12 per linear foot. Doing eavestrough, soffit and fascia together costs meaningfully less than separate visits because the access equipment is shared. For the full regional breakdown see our Calgary roof replacement cost guide.
What moves the number in Canmore
Canmore is more expensive than the prairie for reasons that are structural rather than opportunistic. Fire-rated assemblies cost more than standard architectural asphalt. Design snow loads in the Bow Valley are far higher than in Calgary, so ice and water coverage, fastening and eave detailing all step up. Lots are tight, staging space is limited, and the working season at elevation is genuinely shorter, which compresses scheduling for everybody.
Permits & Local Rules
What applies in Canmore?
Two things apply in Canmore that do not apply elsewhere. First, since March 2018 the Town of Canmore requires a minimum Class B fire rating on all new and repaired roofs. Second, the Town runs a Roof Replacement Incentive that pays single-family homeowners 50 percent of the replacement cost when Class A materials are used, up to $5,000. A like-for-like re-roof does not require a development permit, but the fire rating requirement applies regardless, and the incentive has its own documentation. We quote the Class A option on every Canmore job so the rebate is on the table before you decide.
FAQ
Canmore eavestrough questions.
It can, and it is the main difference between a Canmore system and a prairie one. On a steep mountain roof the load will release, and anything at the eave is in the way. The answer is a combination of fastening, placement, and in some cases snow retention on the roof itself so the release is controlled rather than sudden. We will walk your specific roof and tell you which applies.
Typically more than the prairie equivalent because of access, staging and the heavier specification. A complete seamless aluminum system generally runs $2,000 to $4,500 depending on the home, with six-inch specified more often than not. Downspouts are $100 to $250 each installed.
In Canmore, usually. Steep roofs, deep snowpack and a concentrated spring melt combine to move more water through fewer outlets than a prairie house ever sees. The material cost difference is small next to overflow at a foundation, and it is one of the few places where we recommend the larger size as a default rather than an exception.
Five-inch handles the runoff from most single-family roofs. Go to six-inch if you have a large roof area draining to few outlets, a steep pitch that moves water fast, valleys dumping onto a short run, or mature trees dropping debris. The material cost difference is small next to overflow at the foundation.
Usually pitch, sizing or outlet placement rather than blockage. A run that is level or back-pitched holds water, a five-inch run fed by two valleys can simply be undersized, and too few downspouts creates a bottleneck. We measure the roof area draining to each outlet rather than matching whatever was there before.
Every winter. Standing water in a back-pitched run becomes a solid length of ice, and ice is heavy enough to pull hangers straight out of fascia and take the board with them. Correct pitch and sound fascia are what prevent it, not thicker aluminum.
