Roof replacement cost in Calgary
Quick answer
Compare squares, tear-off, decking price, shingle class, ice and water protection, ventilation, flashing, GST and warranty. After hail, also compare the quote against the insurer's scope.
Calgary roofs face hail, chinook freeze-thaw swings and snow. Many replacements follow insurance claims, and many homeowners consider impact-resistant shingles. Quotes differ by material class, ventilation, eave protection and how hidden damage is priced. A fair quote makes the system and any insurance difference clear.

What most people miss
Insurance scope and upgrade cost are two different things
After a hail claim, the insurer usually pays to restore what you had. Upgrading to impact-resistant shingles may cost extra, though some insurers offer premium discounts for them. Ask the roofer to separate the insured scope from any upgrade you are paying for yourself.
How this price is built
Squares and pitch
Measured area and slope drive material and labour.
Tear-off and disposal
Layers removed and bin costs should be stated.
Decking
Replacement sheathing should carry a per-sheet price.
Ice and water protection
Eaves, valleys and penetrations need membrane protection against ice damming.
Shingle class
Standard versus impact-resistant shingles should be named by product.
Ventilation
Intake and exhaust vents help limit moisture and ice dams in winter.
Flashing and eavestrough
Note whether flashing, drip edge and eavestrough work are replaced or reused.
Permit, GST and warranty
Confirm permit status, GST and both manufacturer and workmanship warranties.
What makes a quote high
Door-knocking after a hailstorm
Take time to verify the company, insurance and local references.
Insurance deductible 'covered' by the contractor
Offers to waive or hide a deductible can create problems with your claim.
Upgrade cost mixed into claim work
Ask for insured scope and upgrade cost separately.
Undisclosed decking cost
Hidden damage should be priced per sheet before work starts.
Ventilation ignored
Poor ventilation can shorten roof life and void warranties.
Itemised versus vague
A quote you can evaluate looks different from one you can't. This is what to look for, line by line.
| Item | A quote you can judge | A quote you can't |
|---|---|---|
| Area | Squares and pitch stated | Whole roof |
| Shingle | Product and impact class named | Architectural shingles |
| Ice protection | Membrane locations listed | Standard underlay |
| Insurance | Claim scope and upgrades separated | Insurance covers it |
| Total | GST and warranty stated | Plus tax |
Questions to ask before you approve
- How many squares and layers are included?
- What shingle product and impact rating are you using?
- Where will ice and water membrane be installed?
- How will ventilation be handled?
- What is the price per sheet of replacement decking?
- Which items are insurer-covered and which are upgrades I pay for?
- Is GST included?
- What workmanship warranty do you offer in writing?
What to ask a Calgary roofer
Copy these lines as they are. Politeness plus specifics gets answers.
- 1.“Please separate the insurance scope from any upgrades.”
- 2.“Which shingle product and impact class are you installing?”
- 3.“Where does the ice and water membrane go?”
- 4.“Is GST included, and what is your workmanship warranty?”
When a high price is legitimate
A higher-than-expected price isn't automatically a bad one. These are the situations where it's usually justified.
- Impact-resistant shingles cost more than standard shingles.
- Steep, complex roofs require more labour and safety equipment.
- Proper ventilation and ice protection add material.
- Demand spikes after major hailstorms.
- Hidden deck damage may require replacement.

Common questions
What drives roof replacement cost in Calgary?

Are impact-resistant shingles worth it in Calgary?
They cost more but may resist hail better, and some insurers offer premium discounts. Ask your insurer and compare the extra cost.
Will insurance pay for an upgrade?
Usually insurance restores like-for-like. Upgrades may be your cost. Ask the roofer to separate the two.
Should a contractor cover my deductible?
Be cautious. Your deductible is part of your policy, and offers to absorb or hide it can create claim issues.
