Roof replacement cost in Edmonton
Quick answer
Compare roof area in squares, shingle brand and line (including hail-impact rating), how much ice and water shield is included, the ventilation plan, decking price per sheet, disposal, and written warranties. Edmonton bids vary most on membrane coverage and shingle tier, not on the base shingle.
Edmonton roofs take a beating: hail storms, chinook freeze-thaw cycles, and months of snow load. That's why the details in a quote matter — the extent of ice and water shield at eaves and valleys, whether the shingles carry an impact rating for hail, and whether attic ventilation and insulation are addressed so ice dams don't form. Two quotes with the same shingle can differ widely on these lines.

What most people miss
Ice and water shield coverage is where cheap bids cut
Building code requires self-adhered membrane at eaves, but the coverage distance varies — and valleys, skylights and wall intersections benefit from it too. A quote with membrane only at the minimum eave line is cheaper than one wrapping valleys and penetrations, and the difference shows up as ice-dam leaks in February. Ask exactly where the membrane goes.
How this price is built
Tear-off and disposal
Removal of existing layers, bin and haul-away. Note how many layers are coming off.
Decking
Inspection after tear-off, with replaced sheathing priced per sheet.
Ice and water shield
Self-adhered membrane at eaves (and how far up), valleys, and around penetrations — the line that separates thorough bids from minimum-code ones.
Underlayment
Synthetic or felt underlayment across the rest of the deck.
Shingles
Brand, product line and impact rating. Class 3 or 4 impact-rated shingles cost more but stand up to hail and may earn insurance discounts.
Ventilation
Ridge vent and intake balance sized to the attic — critical for ice dam prevention in Edmonton.
Flashing, drip edge and accessories
New metal flashing, drip edge, plumbing boots and ridge cap.
Warranty
Manufacturer warranty and the contractor's workmanship warranty, in writing.
What makes a quote high
Storm-chaser crews after hail
After a hailstorm, out-of-province crews knock doors and push fast signatures. Check for a real Edmonton presence and WCB coverage before signing.
Minimum membrane coverage
Eave-only ice and water shield meets minimum code but leaves valleys exposed. Compare membrane scope, not just shingle brand.
Designer shingle default
Premium designer lines are sometimes quoted without being asked. Request an architectural-line alternative on the same scope.
Unpriced decking
Without a per-sheet rate, wood replacement is open-ended once the old roof comes off.
Ventilation ignored
A quote that doesn't address attic ventilation can shorten the new roof's life and void warranty terms.
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 measured, waste factor stated | Whole roof |
| Membrane | Ice and water shield locations itemized | Ice guard included |
| Shingle | Brand, line and impact rating named | Premium shingles |
| Decking | Per-sheet replacement price stated | Wood as needed |
| Warranty | Manufacturer and workmanship terms in writing | Lifetime roof |
Questions to ask before you approve
- How many squares is my roof, and what waste factor did you use?
- Exactly where does the ice and water shield go — eaves only, or valleys and penetrations too?
- Which shingle line are you quoting, and is it impact-rated for hail?
- What's your price per sheet for replaced decking?
- How are you handling attic ventilation, and is it included?
What to ask an Edmonton roofer
Copy these lines as they are. Politeness plus specifics gets answers.
- 1.“Please itemize squares, tear-off, membrane locations, underlayment and shingle by brand and line.”
- 2.“Is this shingle impact-rated, and what's your per-sheet price for decking?”
- 3.“How are you handling ventilation, and what are the written warranty terms?”
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-rated shingles cost more and make sense in Edmonton's hail belt.
- Multiple layers need tear-off, adding labour and disposal.
- The roof is steep, high or cut up with valleys and dormers.
- Significant decking or fascia replacement is needed after tear-off.

Common questions
How much does a roof replacement cost in Edmonton?
It depends on squares, pitch, shingle tier, membrane coverage, decking condition and disposal. Compare itemized quotes on those lines — this guide doesn't invent a city average. The roof calculator can give you a planning range for your area.
Are impact-rated shingles worth it in Edmonton?
Often yes. Edmonton gets regular hail, and Class 3 or 4 impact-rated shingles resist it better. Some insurers offer premium discounts for them — ask yours before choosing.
When is roofing season in Edmonton?
Most work happens May through October. Shingles can be installed in cold weather with extra care, but spring booking often means better scheduling. Be wary of anyone pushing a mid-winter tear-off without a clear reason.
Do I need a permit to replace my roof in Edmonton?
Like-for-like residential reroofing generally doesn't require a permit, but structural changes do. Ask each bidder to confirm for your scope.
