Annual Roof Maintenance Checklist for Calgary Homes

Quick Answer: A complete annual Calgary roof maintenance checklist runs on a twice-yearly cadence: spring (April/May) for winter damage and pre-summer prep, fall (September/October) for winterizing. Add event-driven checks within 48 hours of any hailstorm and 2 weeks of any wind event over 90 km/h. Core tasks include eavestrough cleaning, flashing inspection, vent boot check, attic moisture inspection, ventilation balance verification, and documentation photos.

Most Calgary homeowners do less roof maintenance than their warranty requires, and most discover this only when they file a claim that gets denied. The good news: a clear checklist solves the problem. This article gives you the complete month-by-month schedule, the specific tasks for each season, what to document, and when to call a professional.

The Spring Inspection Checklist (April or May)

Run through every item.

Outside, ground-level:

• [ ] Walk the perimeter, looking up at the roof with binoculars

• [ ] Note any missing, lifted, or damaged shingles

• [ ] Check eavestroughs for visible damage from ice damming

• [ ] Inspect fascia for paint damage, rot, or sag

• [ ] Look for displaced ridge cap or ridge vent components

• [ ] Photograph anything unusual

Eavestroughs and downspouts:

• [ ] Clean out all debris (leaves, branches, granules)

• [ ] Test water flow with a garden hose

• [ ] Confirm downspouts drain away from the foundation

• [ ] Check for separation at seams

Flashing inspection:

• [ ] Chimney flashing (step and counter) for rust, lift, or sealant failure

• [ ] Skylight flashing for visible damage

• [ ] Sidewall step flashing for lifted edges

• [ ] Vent boots for rubber cracking

Attic check:

• [ ] Look for water staining on rafters or sheathing

• [ ] Check for mould growth

• [ ] Verify soffit vents are clear (not blocked by insulation)

• [ ] Confirm ridge vent or box vent function

• [ ] Note insulation depth (R-50 is the Calgary standard)

• [ ] Look for daylight through deck (indicates openings)

Documentation:

• [ ] Time-stamped photos of all areas

• [ ] Notes on any damage found

• [ ] Service log entry with date and findings

The Fall Inspection Checklist (September or October)

The pre-winter check is the most important inspection of the year.

Eavestroughs (critical):

• [ ] Complete cleaning of leaves and debris

• [ ] Confirm downspouts are clear and draining

• [ ] Check for any wear or damage from summer storms

• [ ] Trim back any branches dropping debris

Roof surface:

• [ ] Check for hail damage from summer events

• [ ] Note any granule loss patterns

• [ ] Look for lifted or curled shingles

• [ ] Inspect the ridge cap and the ridge vent

• [ ] Confirm all penetrations are sealed

Pre-winter sealants:

• [ ] Re-caulk any flashing edges that have degraded

• [ ] Address any minor flashing issues before the snow

• [ ] Replace any boots showing UV cracking

Attic winterizing:

• [ ] Verify soffit vents are clear for cold-weather ventilation

• [ ] Check insulation depth

• [ ] Inspect for any new moisture signs

• [ ] Confirm air sealing at attic floor (recessed lights, plumbing penetrations)

Heat cables and ice prevention:

• [ ] Test heat cables if installed

• [ ] Check thermostat function

• [ ] Replace any damaged cable sections

• [ ] Plan for heat cable installation if your home has chronic ice dams

Tree and branch:

• [ ] Trim back any branches touching or overhanging the roof

• [ ] Remove any dead branches that could fall during winter storms

Event-Driven Checks

Weather events override the calendar.

After a hailstorm with stones 25 mm or larger:

• Within 48 hours: ground-level photos and binocular inspection

• Note suspected damage zones for professional assessment

• File an insurance notice if damage is visible

• Schedule an HAAG-certified inspection if the claim is likely

After a wind event over 90 km/h:

• Within 2 weeks: full perimeter check

• Look for missing or lifted shingles

• Check fence and tree damage near the house

• Document anything unusual

After heavy snow load:

• Watch for unusual sag at the roofline

• Check for ice dam formation at eaves

• Listen for unusual creaking from the attic

After tree damage:

• Same-day inspection from ground level

• Professional inspection of any branches contacted the roof

• Insurance documentation if damage occurred

Documentation: What to Keep and Why

Documentation matters more than most homeowners realize. It serves three purposes:

1. Warranty claim support. Manufacturers often request maintenance records when warranty claims are filed.

2. Insurance claim strengthening. Time-stamped photos showing pre-storm conditions help adjusters identify storm-specific damage.

3. Resale value. A documented maintenance log signals to buyers that the roof has been properly cared for.

What to keep:

• Photos from every inspection, time-stamped

• Written notes of findings and any work performed

• Receipts from any maintenance work (DIY supplies or professional services)

• Original install paperwork, including manufacturer warranty

• Any storm-event documentation (weather data, insurance correspondence)

Store digitally in a folder you can easily share with insurance adjusters or potential buyers.

When to Call a Professional Mid-Year

Even with an annual Calgary roof maintenance checklist, don't wait for the next scheduled inspection if you see:

• Active interior water staining

• Missing or visibly damaged shingles

• Visible flashing damage

• Active ice dam formation

• Tree contact with the roof

• Unusual interior smells (mould)

Calgary contractors typically respond same-day to active issues and within 7 days to non-emergency maintenance requests.

Frequently Asked Questions

Do I really need two inspections per year?

In Calgary's climate, yes. Winter damage (ice dams, wind, freeze-thaw) shows up in spring; summer damage (hail, UV, storms) shows up in fall. Single-inspection cadences miss one or the other.

How long does a full inspection take?

DIY: 1 to 2 hours for thorough work. Professional: 45 to 90 minutes typically. The professional check is faster because of the equipment and experience.

Can I skip inspections in years without weather events?

Even without major events, normal aging and small failures need attention. Skipping years compounds problems. Stick to the twice-yearly cadence regardless of weather.

What if I find a problem during my own inspection?

Document it and call a contractor for assessment if you can't safely fix it yourself. Most small issues are cheap to address early; the same issues become expensive 6 months later.

Should I keep written records or photo records?

Both. Written log entries summarize what was done and what was found. Photos provide visual documentation that's harder to argue with during insurance or warranty disputes.
