A damaged roof is rarely what costs the most. The water that comes through it afterwards is. Once a roof is open, every hour of rain or melting snow soaks insulation, stains ceilings, swells flooring and reaches wiring. I think that is the most useful thing a homeowner can know going in: the size of the final bill is mostly decided in the first day.
That makes emergency roof repair a different job from ordinary roofing. The goal is not a finished roof. It is to stop water entering, make the house safe, and record the damage properly so the permanent repair and the insurance claim go smoothly.
I wrote this guide for Calgary homeowners who want a plan before they need one. It covers what counts as an emergency, why roofs here fail suddenly, what to do in the first 24 hours, how temporary and permanent repairs differ, and how to pick a roofer under pressure.
What Counts as an Emergency
A roofing emergency is any damage that lets water in now or makes the building unsafe. Everything else can wait for a scheduled visit, which is cheaper.
Call for emergency service when you see:
- Water actively dripping or running into the house
- A hole or puncture from a fallen tree, branch or debris
- Large sections of shingles or membrane torn off by wind
- A ceiling that sags or bulges, which means water is pooling above it
- Flashing ripped away around a chimney, vent or skylight
- A roof deck that sags or has shifted under snow load
These can usually wait a few days:
- A few missing or lifted shingles with no leak
- Granules collecting in the eavestroughs
- An old water stain that is dry and not growing
If you are unsure, a phone call and a few photos are normally enough for a roofer to tell you which group you are in.
Why Calgary Roofs Fail Suddenly
Calgary is one of the hardest cities in Canada on roofs, and hail is the main reason. The hailstorm of August 5, 2024 caused nearly $2.8 billion in insured damage and more than 130,000 claims, according to the Insurance Bureau of Canada. IBC ranked it the second-costliest insured event in Canadian history and said almost one in five Calgary homes was affected.
Hail is not the only cause. Four forces account for most sudden failures here.
-
Hail
Large stones crack shingles, knock off the protective granules and puncture vents and skylights.
-
Wind
Strong gusts off the foothills lift shingle edges, break the seal strip and peel whole sections back.
-
Chinooks and ice dams
A warm spell melts roof snow, the meltwater refreezes at the cold eaves, and the ice backs water up under the shingles.
-
Snow load
A heavy, wet spring snowfall puts real weight on older or low-slope roofs.
The common thread is speed. A roof can go from sound to leaking in a single afternoon.
The First 24 Hours
The order matters more than the speed. Work through these steps in sequence.
-
Make it safe
Keep people away from sagging ceilings. If water is near light fixtures or outlets, switch off power to that area at the panel.
-
Stay off the roof
A wet, damaged or icy roof is dangerous even for professionals with harnesses. Assess from the ground and from the attic.
-
Contain the water
Put buckets under drips and move furniture and electronics. If a ceiling is bulging, pierce the lowest point with a screwdriver over a bucket so it drains in a controlled way.
-
Document everything
Take photos and video of the roof from the ground, the attic, the ceilings and any damaged belongings before anything is moved or patched.
-
Call an emergency roofer
Ask how soon they can attend and what the call-out covers.
-
Call your insurer
Report the damage, ask what is covered and ask how they want temporary repairs handled.
-
Keep every receipt
Tarps, emergency call-outs and hotel stays may be claimable.
Step four is the one people skip in a panic, and it is the one an adjuster asks about first.
Temporary vs Permanent Repairs
An emergency visit normally ends with a temporary repair, and that is the correct outcome. Permanent work needs dry conditions, matched materials and often an adjuster’s approval.
| Temporary repair | Permanent repair | |
| Purpose | Stop water entering now | Restore the roof to full service |
| Typical work | Tarping, roofing cement, sealing flashing, boarding a hole | Replacing shingles, underlayment, decking and flashing |
| When it happens | Same day, in almost any weather | Days or weeks later, in suitable weather |
| How long it lasts | Weeks to a few months | The remaining life of the roof |
| Insurance | Usually expected of you, to limit further damage | Usually needs the insurer’s assessment first |
A proper tarp is more than a sheet thrown over the hole. It should run past the ridge so water cannot get under the top edge, and be fastened along battens so wind cannot lift it.
I would get the scope of the permanent repair in writing at the same visit, even if the work is weeks away.
Insurance: Getting the Claim Right
Most home policies expect you to take reasonable steps to prevent further damage, which is exactly what a temporary repair is. Check your own policy wording, because coverage for hail and wind varies and some policies settle older roofs at a depreciated value.
A few habits make a claim easier:
- Report the damage as soon as it is safe to do so.
- Send the dated photos and video you took before any repair.
- Do not throw out damaged materials until the adjuster has seen them or agreed.
- Ask the roofer for a written report describing the cause and extent of damage.
- Do not sign a contract for full replacement until the insurer has confirmed what it will pay.
For claim questions, IBC runs a Consumer Information Centre at 1-844-227-5422. It also points homeowners to hail-resistant roofing and to the City of Calgary’s Resilient Roofing Rebate Program, so ask whether an upgrade makes sense when the permanent repair is done.
How to Choose a Roofer Under Pressure
Big storms bring out-of-town crews who knock on doors, take deposits and leave. A few questions on the first call separate them from established local roofers.
- Do you have a local address and a City of Calgary business licence?
- Can you show proof of liability insurance and WCB coverage?
- What does the emergency call-out cost, and what does it include?
- Will you give me photos and a written damage report for my insurer?
- Will the same company do the permanent repair, and is that warranty in writing?
- If you take a deposit, do you hold Alberta’s prepaid contracting licence?
The best time to ask is before a storm. Save one or two roofers’ numbers in your phone now, and you will not be choosing from whoever answers at midnight.
The SP Roofing offers emergency roof repair with 24/7 help. Put the same questions to them as to anyone, and confirm response time for your area when you call.
The Bottom Line
In a roofing emergency, the roof is the smaller problem and the water is the bigger one. Make the house safe, stay off the roof, document the damage, get a proper temporary repair and call your insurer. Do those five things on the first day and the permanent fix becomes a routine job instead of a renovation.
Frequently Asked Questions
1. What Should I Do First When My Roof Starts Leaking?
Make the area safe, catch the water and take photos. Then call an emergency roofer and your insurer. Do not climb onto the roof yourself.
2. Can a Roof Be Repaired in Winter or During a Storm?
Temporary repairs such as tarping and sealing can be done in most conditions once it is safe to work. Permanent shingle work usually waits for dry, milder weather so the materials seal properly.
3. Will My Insurance Cover Emergency Roof Repair?
Sudden damage from hail, wind or a fallen tree is commonly covered, and reasonable temporary repairs usually are too. Damage from wear or poor maintenance usually is not. Your own policy decides, so confirm with your insurer.
4. How Long Can a Tarp Stay on a Roof?
A well-installed tarp is a short-term fix measured in weeks to a few months. Sun and wind wear it down, so book the permanent repair as soon as the insurer and the weather allow.
5. How Much Does Emergency Roof Repair Cost?
It depends on the time of day, the size of the damaged area, roof pitch and access. I have no reliable single figure. Ask for the call-out fee and what it includes before the crew is sent.
