Fratello Roofing & Exteriors Ltd billed 106 roof repairs at a median of $1,101. A quarter came in under $375. A quarter ran past $2,500. The largest single repair reached $14,500.
Those figures come from our own invoices, 836 documents issued between August 2019 and August 2026, parsed down to 1,818 priced line items.
Repair pricing confuses homeowners because the word covers a $150 flashing reseal and a $14,500 structural rebuild. This page separates them.
What do repairs cost by the actual job?
| Repair | Times billed | Median | Range |
|---|---|---|---|
| Chimney flashing | 103 | $150 | $100 to $3,200 |

| Skylight reflash | 32 | $275 | $100 to $1,556 |
| Rotten plywood or decking | 28 | $382 | $250 to $1,755 |
| Emergency service call | 54 | $475 | $0 to $4,025 |
| General leak repair | 106 | $1,101 | $375 to $2,500 (middle half) |
| Eavestrough, soffit and fascia | 82 | $2,869 | $755 to $4,675 (middle half) |
Read that table as a ladder. Most Calgary roof leaks resolve at the bottom two rungs. The jobs that reach four figures are the ones where water travelled before anyone noticed.
Where do Calgary roofs actually leak?
Across 836 documents, 242 mention a chimney and 102 mention a skylight. Those two penetrations, not the shingle field, generate the majority of our repair calls.
Chimneys leak because flashing fails, not because the shingles fail. A chimney interrupts the roof plane, and the metal that seals that interruption moves with every freeze-thaw cycle Calgary throws at it. We reflash chimneys at a median of $150. When the chimney itself needs rebuilding rather than resealing, the price climbs toward the $3,200 top of our range.
Skylights leak at the flashing kit and the seal, and every skylight eventually needs attention. We reflash skylights at a median of $275. Full details on what skylight work costs.
Valleys and eaves leak from missing or undersized ice and water membrane. 587 of our documents specify ice and water membrane or synthetic underlayment, because Calgary ice damming demands it. Roofs built without a 4-foot eave membrane show up in our repair records repeatedly.
Can you repair just part of a roof?
Yes, and we do it constantly. 106 of our invoices cover partial repair rather than replacement.
Partial repair works when three conditions hold:
- The damage is localised. A single valley, one chimney, a wind-lifted section.
- The surrounding shingles have life left. Under roughly 15 years old, still flexible, granules intact.
- A colour and profile match exists. Owens Corning Duration appears in 386 of our documents, so matching a Duration roof is usually straightforward. Discontinued products are not.
Partial repair stops working when the roof is already near end of life. Spending $2,500 patching a 22-year-old roof buys two seasons. That same $2,500 is a quarter of a full replacement at our median of $8,662.
Our rule: if the repair quote exceeds roughly 25% of the replacement quote and the roof is over 18 years old, replace it.
Can you replace just a few shingles?
Yes. Replacing a handful of wind-lifted or cracked shingles sits at the cheapest end of our work, typically bundled into a service call rather than billed as its own line.
Two things make it harder than it sounds. Shingles seal to each other with a thermal adhesive strip, so removing one without damaging four neighbours takes a warm day and a flat bar. And a replacement shingle on a 15-year-old roof will not match, because granule colour weathers.
Cosmetic mismatch is not a reason to skip a repair. Water is.
What does emergency roof repair cost in Calgary?
We billed 54 emergency service calls at a median of $475, ranging from no charge up to $4,025 for major storm response.
An emergency call is warranted when water is actively entering the building, when wind has removed shingles and exposed the deck, or when hail has struck and the roof is now open. Everything else can wait for a scheduled visit and costs less.
Our emergency call volume by year runs 6, 7, 6, 15, 12 and 8 from 2021 through the first weeks of 2026. The 2024 spike tracks that year’s storm season.
Repair or replace: what do our own numbers say?
| Situation | What our records support |
|---|---|
| Roof under 15 years, single leak point | Repair. Median $1,101 restores the roof. |
| Roof 15 to 20 years, multiple leak points | Inspect first, $175. Repair cost stacks fast across multiple points. |
| Roof over 20 years, any significant leak | Replace. Median $8,662 and you reset the clock with a 10 year workmanship warranty. |
| Visible hail bruising, any age | Inspect for insurance, $175 to $350. Insurance may fund replacement. |
| Rotten decking found | Replace the affected deck at a median of $382 regardless of which path you take. |

What is the cheapest way to repair a roof?
The cheapest legitimate repair is the one done early. Our own ladder proves it: a chimney reflash at $150 handles the same leak path that costs $1,101 once water has soaked the decking and $382 more once that decking needs replacing.
Sealant products marketed for DIY roof repair, including flex seal type coatings, bridge a gap temporarily on a flat surface. They do not restore a flashing detail, they do not survive Calgary’s freeze-thaw cycling on a sloped roof, and they contaminate the surface so a proper repair costs more afterward. We have removed them.
The genuinely cheap move is an inspection. We billed 66 at a median of $175 and waived the fee entirely on several when the inspection led into work we performed.
How do you choose a Calgary roofer for repair work?
Ask four questions. Every legitimate contractor answers them in under a minute.
- What is your WCB Alberta account number? Ours is 8913704. Without active WCB coverage, an injury on your roof becomes your exposure.
- What is the workmanship warranty in writing, and does it transfer? Ours runs 10 years and transfers to future homeowners.
- Is disposal included? Our quotes include hauling and disposal of all old material.
- Will you show me the failure before you fix it? Our estimates carry a written roof condition assessment signed by owner Ardit Shkalla.

Frequently asked questions
How much does it cost to have a roof repaired in Calgary?
Fratello billed 106 roof repairs at a median of $1,101. A quarter cost under $375 and a quarter exceeded $2,500. Simple fixes sit lower: chimney reflashing runs a median of $150 and vent replacement $250.
How much does it cost to replace shingles on a roof in Calgary, Alberta?
Replacing a small section of shingles typically bundles into a service call. Full replacement across the roof cost a median of $8,662 across 69 Fratello homeowner jobs. Partial shingle work makes sense only when the surrounding roof still has service life left.
What is the cheapest way to repair a roof?
Catching it early. A chimney reflash at $150 addresses the same leak path that costs $1,101 after water reaches the decking, plus $382 more once decking needs replacing. An inspection at a median of $175 is the cheapest first step.
Can you replace just a few roof shingles?
Yes. The constraints are practical: shingles thermally seal to each other so removal in cold weather damages neighbours, and replacement shingles will not colour-match a weathered roof. Neither problem is a reason to leave water entering the building.
Can you repair just part of a roof?
Yes, and 106 Fratello invoices do exactly that. Partial repair works when damage is localised, surrounding shingles are under roughly 15 years old, and the product still matches. Above 18 years with a repair quote over 25% of replacement, replacing costs less over time.
What is the best time of year for roof repair in Calgary?
Any month works for repair, though shingle sealing strips bond properly above roughly 10 degrees Celsius, so cold-weather repairs need hand-sealing. Fratello’s job volume runs 95 in July against 25 in February, so off-season calls get scheduled faster.
Will flex seal fix a roof leak?
No. Spray and brush-on sealants bridge a gap temporarily on flat surfaces, then fail on sloped roofs through Calgary’s freeze-thaw cycling, and they do not restore a failed flashing detail. They also contaminate the surface, making the eventual proper repair more expensive.
How do you find a good roofer in Calgary?
Ask for the WCB Alberta account number, the written workmanship warranty and whether it transfers, and whether disposal is included. Fratello holds WCB account 8913704 and carries a transferable 10 year workmanship warranty on replacement work.
Where do most roof leaks start?
Penetrations, not the shingle field. Across 836 Fratello documents, 242 mention a chimney and 102 mention a skylight. Flashing at those interruptions moves with every freeze-thaw cycle and fails long before the surrounding shingles do.
Is $30,000 too much for a roof?
For standard asphalt shingles on an average Calgary house, yes. Only 10 of 648 Fratello invoices exceeded $30,000. See the full breakdown on our cost page
What is the most expensive part of replacing a roof?
Labour and shingles by the square, roughly 85% of a typical re-roof. See the full breakdown
