The two roof inspections you need in Winnipeg every year happen in spring (after freeze-thaw and ice dams have done their damage) and in fall (before the next freeze-up). Each takes about 30–45 minutes from the ground and another 20 minutes on the roof if you're comfortable up there, and catching one failing vent boot or lifted shingle in either season saves you a $500–$2,000 interior water repair later.
Why Winnipeg Roofs Need Two Inspections a Year
Winnipeg's climate is harder on roofs than almost any other city in Canada. The freeze-thaw cycle, temperatures swinging from above zero to minus 30 within a week, expands and contracts roofing materials constantly. Ice dams form at the eaves when snow melts and refreezes, lifting shingles and backing water up under the underlayment. Then hail season arrives in May and runs through September, and a single hailstorm can bruise asphalt shingles badly enough that they fail years earlier than their rated lifespan.
A spring inspection catches the damage that winter hid under snow. A fall inspection catches the damage that hail and summer heat left behind, before winter buries it again. Two checks a year, each under an hour, and you know exactly what condition your roof is in before either extreme season hits.
Spring Roof Inspection Checklist (April–May)
Spring is the most important inspection window in Winnipeg. The snow has melted, ice dams have receded, and you can finally see your roof surface.
From the ground:
- Walk around the house and look for asphalt shingles on the lawn, in the gutters, or against the foundation, those are shingles that lifted and blew off during winter wind.
- Check for granule loss. If your gutters are full of black sand-like grit, that's the protective coating wearing off your asphalt shingles. Heavy granule loss means the shingles are nearing end-of-life.
- Look at the flashing around chimneys, skylights, and vent pipes. Flashing that's pulled away from the wall or rusted through is a leak waiting for the next rain.
- Check for sagging or dipping roof sections, that indicates structural issues or trapped moisture.
From the roof (if safe):
- Look for lifted, curled, or cracked shingle tabs. Winnipeg's freeze-thaw cycle causes shingles to crack and split at the nail line.
- Check the vent boots, the rubber collars around plumbing vents. These dry out and crack after a Winnipeg winter, and a cracked vent boot is one of the most common sources of roof leaks.
- Inspect the ridge cap, the shingles along the peak. These take the most wind and sun damage.
- Check for any remaining ice dam damage: lifted shingles at the eaves, damaged gutters, or water stains on the underside of the roof sheathing in the attic.
Inside the attic:
- Look for water stains, dark streaks, or mold on the roof sheathing.
- Check for daylight coming through the roof boards, that's a hole.
- Feel the insulation for dampness. Wet insulation means a slow leak you haven't noticed yet.
Fall Roof Inspection Checklist (September–October)
Fall inspection is about preparing for the freeze. By late September, hail season is winding down, and you need to know what damage the summer storms left behind before the snow flies.
From the ground:
- Look for hail damage on asphalt shingles: dark spots or dents on the shingle surface, or bruising you can feel if you press on the shingle. Hail damage isn't always obvious from the ground, so get close if you can.
- Check for loose or missing shingles after summer windstorms.
- Verify the flashing is still sealed, summer heat can cause the sealant around flashing to soften and shift.
From the roof:
- Clean leaves and debris out of valleys and around vents. Blocked valleys force water under shingles.
- Check the gutters and downspouts. Clogged gutters cause ice dams in winter, water backs up, freezes, and lifts shingles at the eaves.
- Re-check all vent boots and flashing for cracks. If they survived winter but not summer UV, now's the time to find out.
- Look at the condition of the underlayment at any exposed edges.
Before freeze-up:
- Trim tree branches that overhang the roof. Winnipeg snow loads can snap branches onto your roof.
- Make sure your attic ventilation is clear, soffit vents blocked with insulation cause warm air to melt snow unevenly, which creates ice dams.
What to Do if you Find Damage
Not everything needs a roofer. A single lifted shingle tab you can press back down with roof cement. A small crack in a vent boot can be sealed with the right caulk. But if you see any of the following, call a professional:
- Multiple cracked or curled shingles, this is a repair or replacement decision, not a patch job
- Flashing that has pulled away from the wall or chimney
- Water stains on the attic sheathing or interior ceilings
- Granule loss heavy enough that bare fibre mat is showing on the shingles
- Any sign of hail damage on asphalt shingles, this is if you need an insurance claim, and you want documentation
If you're filing a hail or storm damage insurance claim, have a roofer inspect and document the damage before you call your insurer. A proper damage report with photos gives you leverage with the adjuster and prevents the insurance company from downplaying the claim.

- Every vent boot and pipe penetration
- Ridge cap and hip shingles
- Gutters, downspouts, and eavestrough attachment
- Attic ventilation and insulation condition
- Signs of ice dam damage from previous winters
- Structural sagging or soft spots
You get a written report with photos, a clear explanation of what's urgent and what can wait, and a repair-first quote, we tell you what to fix now, what to monitor, and when a full replacement is the smarter financial call.
Pricing: Our inspection is free with any repair quote, or $250 as a standalone assessment for a property you're buying, selling, or just want a professional opinion on. Typical repair costs after inspection: shingle repair runs $200–$1,500, flashing and vent boot repair runs $150–$800, ice dam damage repair runs $200–$1,200, and hail or storm damage repair runs $400–$5,000 depending on severity.
