The Ranking
Our top 7 gutter companies in Calgary
Calgary puts gutters through a hard cycle. Summer storms can dump a lot of rain on a roof in minutes, and hail dents and tears eavestroughs in the same storms that damage shingles and siding. Winter adds heavy snow, then a chinook thaw that melts it fast, then a hard freeze that turns any slow drainage into ice along the roof edge. That is why contractors here talk about slope, hanger spacing, fascia condition and where the downspouts empty, and why several of them check the gutters whenever they quote a roof.
Most Calgary homes get K-style gutters in aluminum, in 5 inch or 6 inch sizes, formed on site so a long run has no joints along its length. Steel is offered as an upgrade by some firms, and copper appears on a few price lists. Gutter guards reduce cleaning for homes under trees, and the larger 6 inch size and extra downspouts suit big roof areas. Where the water goes matters as much as the trough. Downspout extensions should carry roof water well away from the foundation, and you should ask the City of Calgary what drainage rules apply to your lot before pointing a downspout at a neighbour or a lane.
Alberta does not license gutter installers provincially, and the Alberta New Home Buyer Protection program applies only to new homes, so it will not cover a replacement on an older house. Contractors working in Calgary should hold a City of Calgary business licence, carry Alberta WCB coverage and carry liability insurance. Before you sign, ask for the business licence number, a current WCB clearance letter and a certificate of insurance, and check them yourself. Ask also who applies for any permit, whether fascia repair is priced separately, what warranty covers the gutters and how long it lasts. Several companies here publish a warranty for roofing but not for gutters.
Our shortlist follows Google Maps order from a snapshot taken on November 10, 2026. We kept dedicated gutter companies and roofing or exterior firms that clearly list gutter installation, and each company has a staffed street address in Calgary, a working website and a Google rating of 4.5 or higher with at least 50 reviews. Several gutter specialists were left out because Google shows no street address, a home address or a suburban base, and some firms with great ratings only clean gutters.
