EAVESTROUGHS
Seamless aluminum trough, downspouts that put water where it belongs, and a written price before anything comes off the house.
Sizes & materials
Two decisions drive every eavestrough quote, and neither one should come from a brochure. Here’s how we make them on your house.
A 5-inch K-style trough handles the runoff from most residential roofs, which is why it’s on most Calgary homes and most of our installs. Ours is seamless aluminum: each run is roll-formed on site in one continuous length, so the only joints are at corners and outlets. Joints are where troughs leak, so fewer is better.
Big roof areas, steep pitches and long valleys concentrate a lot of water in a hurry. A 6-inch trough with larger downspouts swallows that surge instead of sheeting over the edge. If two slopes drain into one short run on your house, expect us to bring it up.
Doesn’t rust and weighs little. It comes pre-finished in colours that match your fascia and siding, and it’s the material on nearly every install we do. Unless your house gives us a reason to say otherwise, aluminum is what we’ll recommend.
Takes a ladder, a hailstone or a snow slide better than aluminum, but it costs more, and once the coating gets scratched through it can rust. We quote steel where the extra strength earns its price, and we’ll say so plainly when it wouldn’t.
Done or fixable
Eavestroughs rarely fail all at once. They drip at one corner, then sag, then quietly start delivering roof water to your foundation.
Not every problem means new troughs. One bad run can be re-sloped, loose hangers can be re-fastened, and a dripping corner can be resealed. That work is cheap and we’re glad to do it. What we won’t do is keep patching metal that’s finished: if you’re resealing the same seams every spring, the repairs have become a subscription.
Pricing
Treat that range as typical, not a quote. A walkable bungalow with four corners and a few downspouts sits at the low end. Two storeys, steep access, 6-inch trough and extra outlets push toward the top. Most Calgary homes land between $1,500 and $3,500 all in, and leaf protection is priced as its own line so you can see exactly what it adds.
The real number goes in writing before anything comes off the house, and the number on the quote is the number on the invoice.
Freeze-thaw
Calgary winters don’t stay frozen. A chinook strips the snow off your roof in January, the melt runs for the eaves, and whatever doesn’t drain refreezes after dark. A trough with proper slope and clear downspouts moves that water while it’s still liquid. A trough holding standing water freezes into a solid bar, and ice builds on ice from there. That’s why we set slope with a level instead of eyeballing it, and place downspouts where melt can actually leave, not where they’re easiest to hang.
The other half of the ice problem starts inside the attic. Warm air leaking up from the house heats the roof deck, snow melts from underneath, and the runoff refreezes over the cold overhang no matter how well the trough below drains. If you fight thick ice at the eaves every winter, the lasting fix usually starts with attic airflow. Our soffit & fascia page explains how that ventilation works.
One schedule
A tear-off is hard on old eavestroughs. Shingles and nails come down on top of them, and tired troughs rarely take it gracefully. If yours are near the end anyway, replacing them alongside a roof replacement means one schedule, one written quote, and the right sequence at the roofline: drip edge goes on with the roof and the new trough hangs snug behind it, so water has no path to the fascia. Split the jobs a year apart and that detail is easy to get wrong. Both are covered by the same 15-year written workmanship warranty either way.
Questions
Typically $8 to $18 per linear foot installed, and most homes land between $1,500 and $3,500 all in. Length, corners, downspouts, height and access set the price. Those are typical ranges, not a quote. The real number goes in writing before we book anything.
Most Calgary homes are well served by 5-inch trough. We recommend 6-inch when a large or steep roof concentrates water into short runs, because an undersized trough overflows in exactly the storms you bought it for. We measure your roof and tell you which one it needs, with the reasoning.
Depends on your trees. Under mature poplars or spruce, guards pay for themselves in cleanings you stop doing. On a newer lot with nothing overhead, that is money you do not need to spend. We will tell you which camp your house is in and quote it as its own line, so the choice stays yours.
Usually yes, if the troughs are near the end of their life. The old ones take abuse during a tear-off, and doing both together gets the drip edge and trough sequenced correctly at the roofline. One schedule, one written quote. If your roof has years left, we hang eavestroughs on their own all the time.
