Roof Replacement Cost in Calgary (2026 Guide)

Most asphalt shingle replacements on detached Calgary homes run $8,000 to $18,000. That is a typical market range, not a quote. Size, pitch, material tier and roof complexity decide where your home lands, and the only number that counts is a written quote from someone who has measured your roof.

Across four Calgary jobs we quoted recently the totals ran $10,900 to $19,500 before GST. A 19-square two-storey came in at $10,900 to $13,000, a 23-square bungalow at $12,700 to $15,700, a 22-square two-storey at $12,600 to $15,100, and a 26-square cedar-to-asphalt conversion at $16,700 to $19,500. Each one is a range because the shingle grade you pick moves the number. An average would hide that spread, so we publish the jobs instead.

Calgary asphalt shingle replacements work out to roughly $5.50 to $7.50 per square foot, which is $550 to $750 per square. Roofers price by the square, meaning 100 square feet of roof surface, rather than by the foot. That range comes from four real Calgary jobs we quoted, each between 19 and 26 squares, and the top of it is a cedar-to-asphalt conversion where the old cedar has to come off and be hauled away. Pitch and complexity move the per-square number more than size does. A steep or cut-up roof is slower to work on safely and wastes more material, so it sits higher per square than a simple roof covering the same area. The whole-roof number is still the one worth comparing: most Calgary asphalt replacements run $8,000 to $18,000 before GST.

Size and pitch first, then shingle grade. A Calgary roof is measured in squares, and a steeper slope costs more to work on safely. After that it is how many layers of old shingles have to come off, how cut up the roofline is, since valleys, dormers and skylights all add flashing work, how easy the access is for the truck and the bin, and the condition of the decking underneath, which we inspect and replace only where it needs it. Ice and water shield, synthetic underlayment and metal valleys are standard on every job here, not upsells that appear later.

We pull an EagleView aerial measurement of your roof, which reports every slope, pitch and dimension from imagery, and that measurement goes into a written estimate with the scope and materials itemized. The number is measured rather than guessed over the phone, and there is nothing for you to schedule. Roof, siding and eavestrough quotes all work this way. An on-roof inspection and a hail insurance assessment are separate paid services, from $350, waived in full when we do the work.

Only if an insured peril caused the damage, and in Calgary that usually means hail or wind. If your claim is approved, you pay your deductible and the policy covers the rest. Wear and age are not claims. A proper inspection tells you which situation you are in before you spend anything.

In hail country, often, but run the numbers for your own house. Class 4 shingles cost more upfront, they are built to resist the hail that damages standard shingles, and some insurers offer premium discounts for them. Ask yours whether a discount applies before you decide.

If the damage sits in one area and the rest of the roof has life left, yes, and we will quote the repair. Typical Calgary roof repairs run $300 to $1,500. When granule loss and new leaks show up across whole slopes, more repairs are money thrown at a roof that is finished.

Scope. One quote includes ventilation correction, ice and water shield and a written workmanship warranty. Another leaves them out and looks cheaper on paper. Demand line items on every quote so you are comparing the same job, and be careful with door-knockers after hailstorms.
