Roof ventilation and soffit work in Winnipeg typically runs $300–$1,500, but that range shifts a lot depending on how many soffit panels need replacing, whether you're adding intake vents to fix a hot attic, and what your roof deck looks like once we open it up. No two Winnipeg attics are the same, freeze-thaw cycles, May-to-September hail, and years of ice dams leave different marks on every house, so the final cost varies a lot by job size, scope, and site conditions. We quote the actual fix after we're on your roof, not a number pulled from a chart.
If you've been told your attic is "cooking" your shingles, or you can see daylight through cracked soffit panels, this page walks you through what the work involves, what drives the price, and how we handle it in Winnipeg's climate.
What's Included in Roof Ventilation & Soffit Work
Soffit work and roof ventilation are two sides of the same coin. The soffit is the underside of your roof's overhang, it's where cool air enters your attic. That air needs to flow up and out through ridge vents, roof vents, or gable vents. When either side of that system is blocked, your attic overheats in summer and traps moisture in winter. That's how you get ice dams, curled asphalt shingles, and rot in your roof deck.
Our roof ventilation and soffit work covers:
Soffit panel replacement. Cracked, rotted, hail-damaged, or missing soffit panels get pulled and replaced. We match the material and colour to what's already on your house wherever possible. This is the most common soffit job we do, hail season in Winnipeg beats up soffits badly, and freeze-thaw cycles crack cheap vinyl panels within a few years.
Intake vent installation. If your attic runs hot and your soffits are intact but not actually pulling air, we install proper intake vents. This often means cutting new vent openings into existing soffit panels or replacing solid panels with vented ones.
Attic ventilation assessment. Before we touch anything, we check the balance between your intake (soffit) and exhaust (ridge or roof vents). A roof needs roughly one square foot of ventilation per 300 square feet of attic floor, split evenly between intake and exhaust. Most Winnipeg homes we inspect are intake-starved, the ridge vent is fine, but the soffits are blocked or missing entirely.
Vent boot and flashing repair. When we're working around roof vents, plumbing stacks, and exhaust pipes, we check the flashing and vent boots. Cracked boots are a top cause of roof leaks in Winnipeg, and they're cheap to fix now and expensive to ignore. We repair or replace flashing as part of the ventilation job when it's needed.
Ice dam mitigation work. Poor ventilation is a major contributor to ice dams. When your attic stays warm, it melts snow on the roof, and that water refreezes at the cold eaves. Improving airflow through the soffit and ridge vents helps keep the roof deck closer to outdoor temperature, which cuts down on the freeze-thaw cycle that creates dams. We don't promise ventilation alone will eliminate ice dams, it won't, but it's a critical piece of the fix.
Asphalt shingle repair around vents. If we're adding or replacing roof vents, we lift and re-lay the asphalt shingles around the vent base. This is where sloppy roofers cut corners, and it's the first place leaks start. We re-nail, re-flash, and seal properly so the vent is watertight before we leave.
Pricing: What Drives the Cost
Honest numbers first. Roof ventilation and soffit work in Winnipeg starts at $300 and can run up to $1,500. That's a wide spread because the scope varies so much. Here's the breakdown of what we typically see:
| Job | Typical Range | What Affects the Price |
|---|---|---|
| Soffit panel replacement (a few panels) | $300–$700 | Number of panels, material, how high off the ground the overhang is |
| Adding intake vents to existing soffits | $400–$900 | How many vents, access difficulty, whether we're cutting into vinyl or wood |
| Full attic ventilation rebalance | $500–$1,500 | Adding intake and exhaust, replacing blocked or missing vents, repairing roof deck damage found underneath |
| Vent boot or flashing repair | $150–$800 | Type of boot, roofing material, whether shingles need to be lifted |
Every one of those ranges is an estimate, not a quote. The final cost varies a lot depending on job size, scope, and site conditions. A two-storey house with a steep roof in St. James costs more to work on than a bungalow in Transcona with a low pitch. If we find rotted wood under a soffit panel, that adds material and labour. If the existing ventilation was done wrong and we have to undo it before redoing it, that adds time. We tell you exactly what we found and what it costs before we start, no surprises at the end.
Why the range is so wide:
- Roof pitch and height. Steeper roofs and higher overhangs mean more safety equipment, more time, and more skill required. It's simply more expensive to work on a two-and-a-half-storey home than a single-storey one.
- Material. Vinyl soffit is cheaper than aluminum or wood. Aluminum lasts longer in Winnipeg's freeze-thaw cycle but costs more upfront. We'll quote both options and let you decide.
- Underlying damage. Hail damage often cracks soffit panels, but it can also dent the fascia and damage the roof deck behind them. Ice dams can soak the wood under the soffit. If we find damage once we open it up, the repair cost goes up.
- Ventilation complexity. Some homes need a simple panel swap. Others have zero intake ventilation and need a full system installed. That's the difference between a $300 job and a $1,500 job.
Insurance consideration. If your soffits were damaged by hail or a storm, your insurance claim may cover part or all of the work. We provide adjuster-ready damage reports with every inspection, and we document everything with photos. We've worked with every major insurer in Manitoba, and we'll tell you straight whether the damage is likely to be covered or whether it's a wear-and-tear issue you'll pay for out of pocket.

How We Do the Work
Our process is straightforward, and it's the same whether you call us for a leak, storm damage, or a ventilation check.
Inspect the attic and the exterior
We look at your attic's current airflow, check for moisture, and examine the soffits from outside. We also check the ridge vent, roof vents, and gable vents to see what's actually working
Measure the ventilation balance
We calculate your attic's square footage and compare it against your current intake and exhaust. Most Winnipeg homes we inspect are intake-starved, they have exhaust but not enough soffit venting to pull air through
Give you a repair-first quote
The person who inspects your roof is the person who writes your quote. No sales team, no pressure to replace what doesn't need replacing. If a simple soffit panel swap fixes the problem, that's what we quote. If you need a full ventilation system, we'll explain exactly why and what it does
Do the repair
We pull damaged soffit panels, install new intake vents, repair flashing and vent boots, and re-lay asphalt shingles around any roof vents we touch. We clean up the job site before we leave, and we haul away the old material
Verify the airflow
After the work is done, we re-check the attic to confirm air is actually moving from the soffits to the ridge vent. A ventilation system that looks good on paper but doesn't flow is a waste of your money, we make sure it works
Why Choose Roof Repair Winnipeg
Small crew, low overhead, fair pricing. We don't have a call centre, a sales team, or a twelve-truck fleet. The person who answers your phone call is the person who shows up, inspects your roof, writes your quote, and does the repair. That lean structure is why our pricing stays fair, we're not covering the cost of a showroom or a marketing department.
Repair-first quotes. We started this company doing roof leak repair because that's where most Winnipeg roofers do their worst work: patch the ceiling, bill the insurance, and sell a replacement you didn't need. We find the actual source of the problem and fix it properly. When a repair is smarter than a new roof, we tell you. When a new roof is the better call, we tell you that too. But we never recommend a replacement just to pad the invoice.
Winnipeg freeze-thaw experience. This city's climate is brutal on roofs. Freeze-thaw cycles crack soffit panels, ice dams back water up under shingles, and hail season from May to September beats up everything exposed. Our crew has worked through every season Winnipeg has thrown at us. We know what fails here and what doesn't, and we build our repairs to survive the next winter, not just the next week.
Storm response in 24–48 hours. If hail or wind just damaged your roof, we'll get out to you within 24 to 48 hours. We contain the leak, document the damage for your insurance claim, and give you an adjuster-ready report with every inspection.
Honest about insurance. Hail damage to soffits is often covered by insurance. Wear-and-tear cracks from freeze-thaw are not. We tell you which one you're dealing with and help you file the claim properly. We don't inflate damage to help you commit fraud, and we don't downplay legitimate storm damage to save you a headache.
