Eavestrough, Gutters & Downspouts
Eavestrough in
Cochrane, Alberta.
Seamless aluminum formed at your Cochrane address and pitched so chinook meltwater cannot stand and freeze. In this town that is the single most important detail in the whole system.
Eavestrough in Cochrane
What Cochrane actually needs from a eavestrough job.
Cochrane eavestrough lives a harder life than most, and the reason is the chinook. A warm arch does not gently thaw the roof, it dumps the entire snowpack into the gutters in a matter of hours, and then the temperature drops back below freezing overnight. A run that is level or back-pitched holds that meltwater, and by morning it is a solid length of ice. Ice is heavy enough to pull hangers out of the fascia and take the board with them, which is why we replace so much Cochrane fascia at the same time as the trough.
Correct pitch to the outlets is therefore not a nicety here, it is the whole job. So is hanger spacing: we screw hidden hangers into sound wood at proper intervals rather than the wider spacing a builder schedule allows, because the ice load in this town is genuinely higher.
Sizing matters on the newer, steeper rooflines. Homes in Riversong, Fireside and Greystone often concentrate a large roof area into a small number of outlets, and a five-inch run collecting two valleys cannot move what a summer cloudburst delivers. We measure the roof area draining to each outlet and size from that.
About Cochrane
Cochrane is the closest of the Calgary satellite towns to the mountains, which makes it the most chinook-exposed community we work in. It grew 6.4 percent in a single year to roughly 39,400 people, with 913 new homes built in 2025 alone. It also took hen-egg-sized hail on August 5, 2024, sitting on the heavier southwest flank of the storm that produced $2.8 billion in insured damage across the region.

Our Standard
What every Cochrane 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.
Cochrane Pricing
What this costs in Cochrane.
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 Cochrane
Cochrane is the town where access is genuinely a line item. The ridge communities are built into slope, driveways are steep, and staging shingles on a hillside lot takes more time and more hands than a flat suburban pad. Pitch is the other factor. A significant share of Cochrane housing runs steep enough to need roof jacks and fall protection staging throughout, which is a safety requirement rather than an upsell, and it slows the job.
Permits & Local Rules
What applies in Cochrane?
The Town of Cochrane treats a like-for-like re-shingle or re-clad as maintenance, so no development permit is required. A permit applies where the work alters the structure, changes roof shape or height, adds floor area, or follows fire or flood damage. Several Cochrane hillside communities also carry architectural controls and slope-specific requirements, which we confirm before starting.
FAQ
Cochrane eavestrough questions.
Because the chinook melts your roof faster than the gutters can clear it, then refreezes what is left overnight. Three things usually combine: the run holds standing water because the pitch is wrong, an ice dam is forming because heat is escaping into the attic, and the fascia has softened so the hangers have nothing to hold. Replacing the trough alone fixes none of them.
A complete seamless aluminum system on a bungalow, roughly 140 to 180 linear feet, typically runs $1,500 to $2,800. Two-storey homes at 180 to 240 linear feet generally run $2,200 to $4,200. Downspouts are $100 to $250 each installed.
In the older treed streets around Glenbow and Cochrane Heights, they earn their money and reduce the winter blockages that start ice problems. On a newer Fireside or Greystone lot with young landscaping, they are not worth it yet, and we will tell you that rather than adding the line.
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.
