A Calgary roof needs a professional inspection twice a year, in spring and fall, plus a check within days of any hailstorm, and its eavestroughs cleared before the first hard freeze. That schedule exists because Calgary roofs face three loads most Canadian roofs do not see together: summer hail, Chinook wind gusts, and winter freeze-thaw swings that open small cracks wider every cycle. Good Roofing has coordinated 2,800+ Calgary roof installations and repairs since 2014, holds 4.9★ from 237 verified reviews, and runs maintenance visits with a drone so you see every slope in a photo report.

Quick answer — the 60-second version (citation-ready)
Roof maintenance in Calgary means four things: a spring inspection after snowmelt to catch winter damage, a post-hail check after any summer storm, a fall inspection with eavestrough cleaning before freeze-up, and attention after Chinook wind events for lifted or missing shingles. Homeowners can handle the ground-level work: clearing eavestroughs, checking downspouts, watching the attic for frost or stains, and photographing the roof from the yard. Anything on the roof itself, including resealing flashing, replacing shingles and checking for hail bruising, belongs to a licensed roofer, because a fall from a roof is the main risk and walking a cold or wet roof can crack shingles. Most Alberta home policies cover sudden damage such as hail and wind, but not slow wear, so dated inspection photos are your proof when a claim comes. Good Roofing inspects by drone, sends the photo report, and puts any repair in a fixed written quote backed by a 10-year workmanship warranty.

The Calgary roof maintenance calendar
Calgary weather sets the schedule. Each season brings one main threat, and each visit is timed to catch it before the next season makes it worse.
- 01Spring (after snowmelt, usually April to May). Look for what winter did: shingles lifted by Chinook gusts, cracked sealant at chimneys and vent stacks, granules washed into eavestroughs, and water stains on the ceiling from ice dams. This is also your “before” record ahead of hail season, so take dated photos of every slope.
- 02Summer (hail season, June to August). Calgary sits in the stretch of southern Alberta insurers call hail alley. After any storm with hail, check the aluminum around the house first: dented downspouts, eavestroughs, vent caps and air-conditioner fins mean the roof took hits too. Book an inspection within days, because most Alberta policies give you a limited window to report the claim.
- 03Fall (September to October). Clear leaves and granules from eavestroughs, confirm downspouts discharge away from the foundation, reseal any cracked caulking at flashings, and fix every summer repair before the first freeze. A small hail bruise or a lifted tab costs little in October and can let in meltwater all winter. Our fall maintenance page has the pre-winter list.
- 04Winter (November to March). Chinooks can swing temperatures from deep cold to above freezing in hours. Snow melts on the warm upper roof, runs down, and refreezes at the cold eave, which is how ice dams form. Watch for heavy icicles, ice ridges at the eaves, and frost on attic nails. Do not chip ice off the roof yourself; call us if water is getting in. See our winter roof emergency guide.

What you can check yourself, and what needs a roofer
A 15-minute walk around the house and a look in the attic catches most problems early. Stay on the ground and on a ladder only for eavestroughs. Everything on the roof surface is roofer work: crews carry fall protection, and Good Roofing partners carry $5M commercial general liability + WCB covered.
- 01From the yard: missing, curled or lifted shingles, dark patches where granules are gone, sagging rooflines, and moss on north-facing slopes. Use your phone camera zoom and save the photos with their dates.
- 02At the eavestroughs: granules that look like coarse black sand mean the shingles are shedding their protective layer. A few after a new install is normal. Handfuls on an older roof, or after a storm, are worth an inspection.
- 03In the attic: water stains on the deck, daylight around vent stacks, frost on nail tips in winter, and damp insulation. Frost and stains usually point to a ventilation or air-sealing problem, covered on our attic ventilation page.
- 04Inside the house: ceiling stains, peeling paint near exterior walls, and musty closets on the top floor. These often show up weeks after the roof first lets water in.
- 05Roofer only: resealing or replacing flashing, replacing shingles, checking for hail bruising (which often cannot be seen from the ground), repairing vent boots, and anything involving ice dams. Our roof inspection checklist lists every point a professional visit covers.

Flat and commercial roof maintenance in Calgary
Flat roofs need more frequent attention than pitched shingle roofs because water does not run off as quickly. On TPO, EPDM and modified bitumen roofs over Calgary garages, infill homes, retail strips and light-industrial buildings, the failures we see most often start at drains, seams and penetrations. A twice-yearly visit, plus one after any hailstorm, keeps most flat roofs out of the emergency category. For active leaks, our flat roof repair team responds within 4 hours.
- 01Drains and scuppers: clear debris every visit. A blocked drain turns a flat roof into a pond, and standing water finds every weak seam.
- 02Seams and laps: check for lifting or open edges, especially on the south and west sides where sun and Chinook winds work the membrane hardest.
- 03Penetrations and rooftop units: pitch pockets, vent pipes and HVAC curbs are where most commercial leaks begin. Service technicians walking to rooftop units also puncture membranes, so check their path.
- 04Hail and ponding marks: after a storm, look for punctures, bruised insulation under the membrane, and new low spots where water sits for days.

Why maintenance records matter for your warranty and insurance claim
Shingle manufacturer warranties cover material defects, and most exclude damage caused by neglect, so read the maintenance terms in yours. Home insurance in Alberta works on a similar line: policies generally pay for sudden damage from hail or wind and decline slow deterioration as wear and tear. When an adjuster is deciding which one caused a leak, dated photos from your last inspection are the strongest evidence you can hand over. Every Good Roofing maintenance visit produces a drone photo report you keep. If a storm does hit, we meet your adjuster on the roof and document every strike. We have worked claims with Intact Insurance / belairdirect, Aviva Canada, TD Insurance, Co-operators, Wawanesa Mutual and other carriers, and Good Roofing has recovered $14M+ in hail-claim settlements for Calgary homeowners. Our hail claim guide walks through the steps.

When maintenance stops being enough
Maintenance extends a roof's life but cannot reverse age. Widespread granule loss, curling across whole slopes, repeated leaks in different places, or soft decking under foot all mean repairs are now buying months, not years. At that point we tell you in writing, with photos, and price a replacement alongside the repair so you can compare. When you do replace, we don't install Class 1 or Class 3 shingles by default — Calgary’s hail belt requires Class 4 impact-rated. A Class 4 roof also needs less hail-season repair work afterward. Our guide to whether your roof is too old covers the signs by roof age.
