Emergency Roof Repair Calgary

Water coming in? We find it and stop it.

Emergency roof repair is a callout to find and control an active leak before the permanent fix. We do it for commercial, condo and multi-family buildings across Calgary, and we publish what it costs before you call.

What to do while you wait

  • Move stock, equipment and furniture away from the drip.
  • Put a container under it, and keep water away from electrical panels and IT gear.
  • Take photos of the ceiling and anywhere water is showing, and note the time.
  • Keep everyone off a wet, icy or snow-covered roof.

Then call 403-608-9933. Tell us the address, where the water is showing and how fast it is coming in. Water often travels along the deck before it drips, so the stain is rarely right under the hole. Finding where it actually gets in is the first job.

Amazing service! City Roofing & Exteriors got my whole roof replaced in just 10 days from signing the contract. Jacky and Ashley were awesome—they kept me informed the entire time, so I never had to worry about a thing. Highly recommend this team!

Jacky was very professional and easy to communicate with - text, phone call and in person! We were able to get quotes right away and he was not pushy at all when I said I was still shopping around. The whole process was quick and seamless. I appreciate how the crew was very respectful of my neighbour's property by protecting their side using plywood. My neighbour across the street also mentioned that the crew was careful when removing the old shingles. Will recommend!

Signs you need emergency roof repair

It is an emergency when water is coming into the building now, or will with the next rain or melt.

  • An active drip or stream through a ceiling tile, a light fixture or down a wall.
  • Water near electrical panels, rooftop unit penetrations or a server room.
  • Ceiling tiles sagging, or a stain that is growing by the hour.
  • Membrane or edge metal torn or lifted after a windstorm.
  • Water backing up at a blocked drain or scupper, deeper than usual.

An old, dry stain or a slow seep that only shows in heavy rain can usually wait for a booked repair. See flat roof repair in Calgary.

An emergency leak callout on a commercial building usually runs

$1,500 to $5,000 or more

Where a callout lands in that range depends on:

  • How hard the leak is to find and control.
  • The time of the call. Evening, weekend and holiday callouts are often 50 percent higher.
  • Access. Restricted access, steep roofs and heavy debris cost more, and lift equipment is quoted separately.
  • How many buildings or roof areas are involved.

The callout finds and controls the leak. The permanent repair is priced separately, in writing, unless it is agreed up front, so you see both bills before the bigger one starts.

What an emergency callout and the repair after it cost

Typical costs from our commercial rate sheet, for standard roof access and normal conditions.

  • Emergency leak response: $1,500 to $5,000 or more

    A callout to locate and control an active leak. Evening, weekend and holiday attendance is often 50 percent higher.

  • Leak detection inspection: $500 to $750

    Finding where the water gets in when it is not leaking hard right now.

  • Minor roof leak: $600 to $2,800

    A small active leak that needs a repair.

  • Flashing or membrane repair: $500 to $2,000

    Failed flashing, an open seam or a damaged patch of membrane.

  • Storm-related roof repair: $3,000 to $15,000

    Wind or rain finds an existing weak point and opens it up.

  • Water mitigation and drying: $3.00 to $7.50 a square foot

    Extraction, drying equipment, moisture checks and containment inside the building.

  • Snow removal: $500 to $2,500

    Clearing snow off the roof before a melt, or to reach the leak.

Why Calgary roofs start leaking all at once

Most emergency leaks are weather opening a weak spot that was already there. Calgary gives weather a lot of chances: the City counted 54 chinook days in 2022 against an average of 46, and 117 freeze-thaw cycles (City of Calgary).

  • A storm

    Wind lifts an edge or a seam, and the next rain gets under it.

  • Blocked drains

    Snowmelt or rain backs up behind a blocked drain or scupper and finds the nearest weak lap.

  • Failed flashing

    Where the roof meets a wall, a vent or a rooftop unit, the seal gives out.

  • Chinook freeze-thaw

    Snow melts in a warm spell and refreezes overnight at the drains and edges, so the leak comes and goes with the temperature.

  • Hail

    A flat roof faces straight up, and hail can bruise or puncture the membrane without an obvious hole. The August 5, 2024 storm alone caused nearly $2.8 billion in insured damage in Calgary (Insurance Bureau of Canada). See hail damage roof repair.

Emergency roof repair questions

How much does emergency roof repair cost in Calgary?

An emergency leak callout on a commercial building usually runs $1,500 to $5,000 or more. That finds and controls the leak. The permanent repair is quoted in writing after, and minor leak repairs usually run $600 to $2,800.

Do you charge more for evenings, weekends and holidays?

Yes. Evening, weekend and holiday callouts are often 50 percent higher than a standard callout. Our regular hours are Monday to Saturday, 8am to 7pm.

How do I temporarily stop a roof leak?

From inside only: put a container under the drip, move what you can and photograph the damage. Do not go up on a wet, icy or snow-covered roof. Call for a callout instead.

Is the emergency fix permanent?

Not always. The callout is to find the leak and stop the water. Whether that repair will hold, or the area needs a bigger repair, we tell you in writing with photos.

Can you dry out the water damage inside?

Yes. Water mitigation and drying usually runs $3.00 to $7.50 a square foot and covers extraction, drying equipment, moisture checks and containment.

Do maintenance plan clients get priority?

Yes. Preferred includes expedited service response, Premier adds priority scheduling for leak calls between visits, and Portfolio adds priority routing and a priority inspection after a storm. See the three maintenance plans.

How do I pick a roofer for an emergency?

Look for a local office, prices you can see before anyone comes out, photos of what was found and a written scope before the permanent work. Recent Google reviews show how a company communicates on leak calls.
