A full roof replacement in Winnipeg typically costs $8,000 to $15,000 for a standard asphalt shingle roof on an average-sized home, but that range shifts significantly based on your roof's square footage, pitch, number of existing layers, and the condition of the decking underneath, so treat it as a planning number, not a firm quote.
What's Included in a Full Roof Replacement
A roof replacement is a complete roofing-system overhaul, not just a new layer of shingles. Here's exactly what we do on every full tear-off and replacement we run in Winnipeg:
Full tear-off of existing materials. We strip every old shingle, nail, and piece of underlayment down to the bare decking. We never lay new shingles over old ones, that traps moisture and shortens the life of your new roof.
Decking inspection and repair. Once the old roof is off, we inspect the plywood or OSB decking for rot, water damage, and sagging. Damaged sections get replaced before anything goes on top. This is the step most homeowners never see, and it's the step that separates a roof that lasts 25 years from one that fails in five.
Ice and water shield. Winnipeg's freeze-thaw cycle is brutal on roof edges. We install ice and water shield membrane along the eaves, valleys, and around all penetrations, the areas most vulnerable to ice dams and wind-driven rain. This is non-negotiable on every replacement we do.
New underlayment. A full layer of synthetic underlayment goes over the entire deck before shingles. It acts as a secondary waterproof barrier if shingles ever get damaged by hail or wind.
New asphalt shingles. We install architectural asphalt shingles as our standard, they're thicker, more dimensional, and handle Winnipeg's wind and hail better than budget three-tab shingles. You can upgrade to premium impact-rated shingles if you want extra hail protection, and we'll walk you through the price difference honestly.
New flashing. All flashing around chimneys, skylights, plumbing vents, and roof-to-wall intersections gets replaced. Old flashing is a leading cause of leaks on roofs that are otherwise in good shape. New step flashing, counter-flashing, and valley flashing are all part of the job.
New vent boots and pipe collars. The rubber boots around plumbing vents crack and dry out after years of UV exposure. We replace every one of them during a full replacement.
Ventilation work. A roof needs balanced intake and exhaust ventilation to prevent ice dams and premature shingle aging. We assess your current ridge vents, soffit vents, and gable vents, and correct any imbalances as part of the replacement.
Magnetic cleanup. We sweep the entire property with magnetic nail finders after the job. No nails in your driveway, lawn, or tires, period.
Warranty coverage. New roofs come with both a manufacturer's shingle warranty and our workmanship warranty. We'll walk you through what's covered and what isn't before we start.
Roof Replacement Pricing in Winnipeg
Our roof replacements start at $8,000 and run up to $15,000 for most Winnipeg homes. That's a wide range because the final cost depends on factors that vary a lot from house to house, the only way to get a real number is a site inspection.
what drives the price up or down:
Roof size. The single biggest cost driver. A 1,200-square-foot bungalow roof costs far less than a 3,000-square-foot two-storey with multiple dormers. Roofers measure in "squares", one square equals 100 square feet of roof surface. Most Winnipeg homes fall between 15 and 30 squares.
Pitch and accessibility. A steep roof takes longer, requires more safety equipment, and is more dangerous to work on. A low-pitch roof on a single-storey home is faster and cheaper. If your roof is steep, expect the price to climb.
Number of layers. If your roof already has two layers of shingles, tear-off takes longer and disposal costs more. We always check this during the inspection.
Decking condition. If we find rotten or water-damaged plywood after tear-off, replacing it adds to the cost. We can't know the decking condition for certain until the old shingles are off, this is the most common reason a final invoice comes in above a ballpark estimate.
Shingle quality. Architectural shingles are our standard. Impact-rated shingles cost more but can earn you an insurance discount and hold up better in Winnipeg's hail season. We'll quote both options so you can decide.
Flashing complexity. Roofs with lots of valleys, chimneys, skylights, and dormers need more flashing work. A simple gable roof with one chimney is at the low end; a complex roof with multiple intersections is at the high end.
Flat or low-slope sections. If part of your roof is flat or low-slope, that section needs modified-bitumen or PVC membrane instead of shingles. That changes the materials and the labour.
Season. Roof replacements run May through October in Winnipeg. Winter replacements are possible for emergency situations but cost more due to cold-weather challenges and slower work.
Every range we've quoted here is a planning figure. Your final cost depends on your specific roof's size, scope, and site conditions, the only way to get an accurate number is a free on-site inspection and written quote.

Our Roof Replacement Process
We run replacements in a proven sequence. what you can expect from start to finish:
Free inspection and quote
We climb onto your roof, measure every plane, check the decking from the attic side, assess ventilation, and inspect flashing and penetrations. You get a written quote with line items, no vague lump sums. The person who inspects your roof is the person who quotes it and the person who repairs it
Material order and scheduling
Once you approve the quote, we order materials and schedule your replacement. Most Winnipeg replacements are completed in one to three days, depending on roof size and weather
Tear-off
We protect your landscaping, driveway, and walkways with tarps and plywood. Then we strip the old roof completely and haul everything away. You'll see the bare decking by the end of day one on most jobs
Decking repair
We replace any damaged plywood or OSB. We show you photos of any problem areas before we fix them, so there are no surprises on the final invoice
Ice shield and underlayment
Ice and water shield goes down in the vulnerable zones, then synthetic underlayment covers the full deck
Flashing and vent boots
All new step flashing, counter-flashing, valley flashing, and pipe boots go in before a single shingle is laid
Shingle installation
New asphalt shingles go down with proper nailing patterns and exposure. We use the manufacturer's specified nail count and placement, this matters for warranty validity and wind resistance
Ridge vent and finishing
Ridge vent installation, cap shingles, and any final trim work complete the roof system
Magnetic sweep and walkthrough
We clean the entire property with magnetic nail finders, then walk the roof and grounds with you. We show you what we did, where the new flashing is, and how your ventilation is set up. You sign off only if you're satisfied
Why Winnipeg Homeowners Choose Us
Small crew, low overhead. We don't run a twelve-truck fleet with a call centre and account managers. Our overhead is lean, and that shows up in the price. You're paying for roofing expertise, not a sales infrastructure.
No sales team. The person who answers your phone call is the person who inspects your roof, writes your quote, and does the work. There's no handoff, no pressure tactics, and no commission-driven upsell.
Repair-first quotes. We built our reputation on roof leak repair, and we still believe most Winnipeg roofs can be repaired rather than replaced. If your roof has 10 to 15 years of life left and the damage is localized, we'll tell you to repair it. If a replacement is the smarter financial call, we'll show you why with photos and numbers. Either way, you get an honest recommendation.
Storm response in 24–48 hours. Winnipeg's May-to-September hail season keeps us busy. When hail or wind damages your roof, we respond within 24 to 48 hours, contain the damage, and provide an adjuster-ready damage report with every inspection. That report makes your insurance claim smoother and faster.
Freeze-thaw local crew. This city's freeze-thaw cycle, winter ice dams, and summer hailstorms demand a crew that's worked through every season here. We have. We know how ice dams form on Winnipeg roofs, where wind-driven rain gets in during a May storm, and how to install flashing so it survives the next twenty winters.
Every season, every roof type. We replace asphalt shingle roofs on Winnipeg homes of every age and style, from St. Boniface character homes to new builds in Waverley West, and everywhere in between. We also handle flat and low-slope sections, so mixed-roof homes get one crew for the whole job.
