Roof Repair & Leak Diagnosis
Roof Repair in
Cochrane, Alberta.
Hen-egg hail from August 2024, wind on the hillside communities, and the ice damming that follows a Cochrane chinook. We trace leaks to the actual entry point rather than patching the stain.
Roof Repair in Cochrane
What Cochrane actually needs from a roof repair job.
Cochrane sat on the heavier southwest flank of the August 5, 2024 storm, with hail the size of a hen egg recorded in town. Most of the damage that storm did here has still not been repaired, because hail on asphalt almost never leaks on the day. It knocks the granule layer loose and the exposed asphalt then ages under prairie UV far faster than it should. If your roof was on the house that day, it is worth a look regardless of how it appears from the driveway.
The winter list is chinook-driven and it is worse here than east of the city. Meltwater from the warm middle of the roof runs down to a cold overhang and refreezes, and once the dam is tall enough, water backs up behind it and under the lower courses. Shingles shed water flowing downhill; they are not designed to hold a standing pool. In the older Glenbow and Cochrane Heights streets, where mature trees shade north slopes so they never dry, that cycle can run several times in one winter.
And on the hillside communities, wind. The typical failure starts with a tab that never fully sealed, usually because the roof went on in cool weather without hand-sealing, and once one lifts the course above it is exposed and the damage runs along the roof from there.
About Cochrane
Cochrane is the closest of the Calgary satellite towns to the mountains, which makes it the most chinook-exposed community we work in. It grew 6.4 percent in a single year to roughly 39,400 people, with 913 new homes built in 2025 alone. It also took hen-egg-sized hail on August 5, 2024, sitting on the heavier southwest flank of the storm that produced $2.8 billion in insured damage across the region.
Where We Work
Cochrane neighbourhoods we cover.
Our Standard
What every Cochrane roof repair job includes.
Most roof leaks are not where the stain is. Water runs along rafters and under underlayment before it finds somewhere to drop, which is why a patch applied to the wet spot on the ceiling so often fails. We inspect the roof and the attic together, trace the water back to where it actually got in, and repair the cause rather than the symptom. Most repairs are finished the same day.
Diagnosis, not guesswork
We inspect from above and inside the attic, then show you photos of what we found before anything gets fixed.
Flashing repairs
Chimney, skylight, wall and valley flashings resealed or replaced with new metal where the detail has failed.
Vent boots and penetrations
Cracked rubber collars on plumbing stacks are one of the most common leaks we find, and they usually fail long before the shingles do.
Hail and wind damage
Lifted and blown-off shingles replaced and resealed, with impact damage photographed and measured for your adjuster if you need it.
Ice dam damage
Water backed up under the lower courses, damaged eaves, and the ventilation problem that caused it in the first place.
Deck repairs
Soft or rotted sheathing cut out and replaced so the repair is built on something solid.
24/7 emergency response
If water is actively coming in we stop the damage first and repair properly once the roof is dry enough to work on safely.
Honest repair-or-replace advice
If the roof still has years left we repair it and say so. If a repair is money into a roof that is going to fail anyway, we say that instead.
Cochrane Pricing
What this costs in Cochrane.
Real 2026 ranges for the Calgary region. Your written quote gives a firm number after we have been on site, because a price without an inspection is a guess.
Most common repairs
$400 – $1,200
Diagnosed and completed, materials included
Vent boot replacement
$300 – $500
Cracked plumbing stack collar, a very common leak
Valley or chimney flashing
$350 – $1,000
Stepped and counter-flashed properly, not caulked over
Emergency tarping
$350 – $650
Stops the damage while we schedule the real repair
Deck repairs run $70 to $110 per sheet installed. If a repair estimate climbs past roughly 30 percent of a replacement we will tell you, because at that point you are investing in a roof that is going to fail anyway. For the full regional breakdown see our Calgary roof replacement cost guide.
What moves the number in Cochrane
Cochrane is the town where access is genuinely a line item. The ridge communities are built into slope, driveways are steep, and staging shingles on a hillside lot takes more time and more hands than a flat suburban pad. Pitch is the other factor. A significant share of Cochrane housing runs steep enough to need roof jacks and fall protection staging throughout, which is a safety requirement rather than an upsell, and it slows the job.
Permits & Local Rules
What applies in Cochrane?
The Town of Cochrane treats a like-for-like re-shingle or re-clad as maintenance, so no development permit is required. A permit applies where the work alters the structure, changes roof shape or height, adds floor area, or follows fire or flood damage. Several Cochrane hillside communities also carry architectural controls and slope-specific requirements, which we confirm before starting.
FAQ
Cochrane roof repair questions.
Worth checking regardless. Hail damage does not heal, and it is still visible as scattered soft bruising with the granules knocked away. Whether a claim is still open to you depends on your policy and your insurer, but knowing what is actually on the roof is useful either way, because it changes how many years you have left to plan for.
That is an ice dam, and Cochrane produces them more reliably than anywhere else we work. Heat escaping into the attic melts snow on the warm part of the roof, the meltwater refreezes at the cold overhang, and water eventually backs up under the shingles. The permanent fix is air sealing and attic airflow, not new shingles.
Regularly. Cochrane, Bearspaw and the surrounding Rocky View County acreages are part of our normal working area. Acreage roofs are often larger and more exposed, sometimes with a shop or outbuilding in the same project, and we quote them the same way: on site, in writing, itemized.
Often that is exactly the right answer. Localised damage on a roof with good years left is a repair, not a replacement. The honest caveat is colour match: shingles weather, so a repair patch on a fifteen-year-old roof will be visible even using the same product.
Yes, 24/7. If water is actively coming into the house we prioritise stopping the damage, tarping if we have to, then complete a proper repair once conditions allow. A week of water sitting in sheathing and insulation costs far more than the repair does.
We document hail and storm damage with photos and measurements and give you a written summary your adjuster can use, whether or not you decide to file and whether or not you hire us. If it is wear rather than storm damage we will tell you that too.
