Condo Roofing Calgary
Roofs for condo and multi-family buildings.
Condo roofing in Calgary is the repair, replacement and upkeep of the shared roof on a condo, apartment or multi-family building, arranged with the board or property manager. We give boards a photo report and a written scope they can vote on, and our own crew does the work.
What building owners say about us
Word for word from public Google reviews. Henry Chen wrote: “They installed a new flat roof system for our eight-plex building.”
That is 4.8 stars across 187 Google reviews. Read all of them on Google before you call anyone, including us.
When a condo board should call a roofer
Mark Dawson, our owner, says most first calls start one of two ways: there is a leak, or someone is worried about the state of the roof. These are the signs that usually bring a board to that point.
- Water stains or drips in a top-floor unit or a common hallway.
- Water still standing on the roof a day or two after rain or snowmelt.
- Blisters, cracks, worn granules or open laps in the membrane.
- Patches that keep failing, each one in a new spot.
- A reserve fund study that lists the roof as near the end of its life.
- A hailstorm or a hard wind event over the building.
Not every worried board needs a new roof. On one recent roof, our finding was that “the membrane was in decent condition with no concerns to report.” The assessment tells you which case you are in.
Water coming in right now? Move what you can, put a container under the drip, photograph the ceiling, keep everyone off a wet or icy roof and call 403-608-9933. See emergency roof repair in Calgary.
A flat roof replacement on a condo or apartment building usually runs
$10 to $20 a square foot
Where a building lands in that range depends on:
- How big the roof is.
- What condition the deck is in once the old roof comes off.
- How many drains, vents and rooftop units need flashing.
- Access to the roof.
A 10,000 square foot roof is roughly $100,000 to $200,000. Minor leak repairs usually run $600 to $2,800. You get an itemized written quote after we have seen the roof. For the full breakdown, see commercial flat roof cost in Calgary.
Why a condo roof turns into a board decision
A condo roof is shared property, so every repair is a budget and governance decision, not one owner’s call. In Alberta, that decision sits inside two rules.

-
The reserve fund
Every Alberta condo corporation keeps a reserve fund for major repairs and replacement of common property, and a reserve fund study must be done at least every 5 years, looking 30 years ahead. The reserve fund cannot pay for ongoing maintenance. Source: Government of Alberta, reserve funds.
-
Special levies
If the reserve is short, a board can approve a special levy by resolution, without an owner vote, unless it pays for a capital improvement. Owners must be told the total, how each unit’s share was worked out and when it is due. Source: Government of Alberta, special levies.
-
Slow drainage on a big flat roof
Walk-ups and eight-plexes often have large flat roofs. Water that sits after rain or snowmelt works on the seams, and chinook freeze-thaw opens them further.
-
Deferred upkeep
Because upkeep comes from the operating budget, drains and sealant are easy to skip. Blocked drains and dried sealant at vents and rooftop units are where many leaks start.
Repair, replace, or keep it on a plan
The free roof assessment decides it. Mark looks for blisters, ridges and cracks, granule loss, curling, ponding, impact damage, open laps and dried sealant. A few of these in one area usually means a repair. Most of them across the roof usually means a new one.
Repair it
For a leak in one area on a membrane that is otherwise sound. Minor leaks usually run $600 to $2,800, and flashing or membrane repairs $500 to $2,000. See flat roof repair in Calgary.
Replace it
For wear across the roof or repeat leaks. Usually $10 to $20 a square foot, with a 10-year workmanship warranty. Most of the flat roofs we put on are torch-on with IKO membranes; see torch-on vs TPO vs EPDM.
Keep it on a plan
For a sound roof the board wants kept that way. Scheduled visits clear the drains and roof surface, and each one ends with a photo report.
What your board gets in writing
After the free roof assessment, the board gets three things it can put on the table at a meeting:
- A roof condition record: a photo report of the visible concerns and the next steps.
- A priority action list: what to address now, what to plan for and what to monitor.
- An itemized written scope and quote you can set beside other quotes line by line.
We check the roof surface, the edges and flashings, and the drains and penetrations: membrane, seams, laps, earlier repairs, parapets, copings, curbs, scuppers, ponding, and the seals around pipes, vents, skylights and rooftop units.
The priority list is what keeps a special levy from being a surprise. It shows the board what has to happen this year and what can be planned into the reserve fund. We are a roofer, not a reserve fund study provider: our report gives your study provider the current condition of the roof.
An inspection covers the safely accessible, visible areas of the roof, and maintenance does not guarantee a leak-free roof. More on commercial roof inspection in Calgary.

Maintenance plans for boards and portfolios
- Preferred: one visit a year, for roofs up to 15 years old. Usually $0.18 to $0.27 a square foot.
- Premier: two visits a year, for roofs 5 to 20 years old, with priority scheduling for leak calls between visits. Usually $0.29 to $0.36 a square foot.
- Portfolio: three visits a year for property managers looking after several roofs, with priority routing, a budget priority matrix and a priority inspection after a storm. Priced to the portfolio.
On Premier and Portfolio, each report adds budget notes and a reserve fund section. Every plan is priced for your property, and the exact scope is agreed in writing before work begins. See the condo roof maintenance plans.

Condo roofing questions
How much does a condo roof replacement cost in Calgary?
A flat roof replacement on a condo or apartment building usually runs $10 to $20 a square foot, so a 10,000 square foot roof is roughly $100,000 to $200,000. You get an itemized written quote after we have seen the roof. Learn more about commercial flat roof cost in Calgary.
Is it cheaper to repair or replace a condo roof?
A repair is cheaper when the leak is in one area and the rest of the membrane is sound. Minor leaks usually run $600 to $2,800. Repeat leaks, or wear across the whole roof, usually point to replacement. See flat roof repair in Calgary.
What is the most expensive part of replacing a flat roof?
The size of the roof first, then the condition of the deck once the old layers come off. Drains, vents and rooftop units that need flashing, and difficult roof access, add to it.
Who pays when the roof leaks into a unit?
It depends on your registered condominium plan, your bylaws and the corporation’s insurance, so check those or ask your property manager or lawyer. What we do is find the cause on the roof and document it with photos, so the people deciding have the facts.
Can you give our board something for the reserve fund study?
Yes. The free roof assessment comes with a photo report and a priority action list, and Premier and Portfolio plan reports add budget notes and a reserve fund section. In Alberta, a reserve fund study must be done at least every 5 years; our report gives your study provider the roof’s current condition.
Can a board charge owners a special levy for a new roof?
In Alberta, a board can approve a special levy by resolution without an owner vote, unless it pays for a capital improvement (see the Government of Alberta). A priority action list helps a board plan the roof into the reserve fund instead of levying in a rush.
We manage several buildings. Can you look after all of them?
The Portfolio plan is built for that: three scheduled visits a year, priority routing, a budget priority matrix for immediate and future work, and a priority inspection after a storm. It is priced to the portfolio.
What warranty do you give?
Flat and commercial roofs carry a 10-year workmanship warranty, in writing with your quote.
