Inside London's Roof Replacement Market - Real June 2026 Prices

$45,000 CAD. That is what some London homeowners paid for a high-end roof replacement this year. If that number makes your stomach drop, don't panic. While the ceiling for premium materials is high, the average London homeowner is paying $12,394 CAD to get a new roof over their head right now. We are seeing a range from $5,500 to $45,000 CAD depending on what you're building. If you feel like prices are higher than when you last checked, you're right. Costs in the Forest City have climbed 8.5% since this time last year. Figuring out why your quote looks the way it does is the first step to making sure you don't overpay.

How Much Does Roof Replacement Cost in London?

When you start looking at quotes, you'll see a massive gap between the low and high ends. A budget project, typically sitting around that $5,500 mark, usually covers a straightforward asphalt shingle replacement on a smaller bungalow. Think of the post-war wartime houses you see in the Carling or Hamilton Road neighborhoods. These are simple "up and over" roofs with few valleys or peaks.

The average cost of $12,394 is what you’ll likely see for a standard two-storey detached home in areas like Oakridge or Byron. This price usually includes the tear-off of one layer of old shingles, minor plywood repairs, new underlayment, and standard architectural shingles. It also covers the disposal fees, which have been creeping up at local facilities like the W12A Landfill.

On the high end, hitting $45,000, you are looking at premium materials like slate, cedar shakes, or high-end standing seam metal. These projects often involve complex rooflines with multiple dormers, skylight replacements, and perhaps structural reinforcement for heavier materials. In London, these are common for the historic estates in Woodfield or the sprawling custom builds in Sunningdale.

What Affects the Cost?

Several factors dictate where your quote lands within that wide range. First is the pitch and complexity. A steep roof requires more safety equipment and takes longer to navigate. If your home has multiple gables and dormers, your labor costs will spike because of the intricate flashing work required to keep the water out.

Material choice is the biggest variable. Asphalt shingles remain the most popular choice because they are cost-effective, but metal roofing is seeing a surge in London as homeowners look for "lifetime" solutions. While metal costs more upfront, it handles our humid summers and heavy winter snow loads better than basic shingles.

The London labor market is another piece of the puzzle. We have a steady demand for trades here, partly due to the ongoing residential expansion in the north and west ends. You aren't just competing with your neighbors for a crew; you're competing with new subdivision developers. This keeps labor rates firm.

Permits and inspections also play a role. While a simple shingle-for-shingle replacement might not always trigger a heavy permit process, any structural changes or major flat-roof conversions will require a visit to the City of London building department. Finally, seasonal timing matters. June is the start of the "peak" season. Everyone wants their roof done before the autumn rains, so you'll pay a premium for a spot on the calendar right now.

How London Compares to Other Canadian Cities

London sits right in the middle of the pack when it comes to Southwestern Ontario pricing. Our average of $12,394 is slightly higher than Oshawa, where homeowners pay $11,588 on average. This is often due to the sheer volume of roofing companies operating in the GTA fringe, which can lead to more aggressive pricing.

However, we are cheaper than our neighbors to the west. In Windsor, the average price hits $12,755. Windsor often deals with higher humidity-related wear and a different labor pool dynamic. If you look across the country, the differences are even more stark. In Kelowna, the average jumps to $16,718, largely due to the high cost of living and the difficulty of transporting materials into the interior of BC.

Closer to home, Barrie comes in at $13,568. Barrie’s higher price point is often attributed to the "snow belt" requirements; roofs there often need more robust ice and water shielding to handle the massive lake-effect snow piles, which adds to the material and labor tally. London’s prices are relatively stable compared to these outliers, but the 8.5% YoY increase shows we are catching up quickly.

How to Save Money on Roof Replacement

The best way to save money is to avoid the "emergency" tax. If you wait until water is dripping through your ceiling, you lose all your bargaining power. Start getting quotes while your roof is still functional but nearing the end of its life.

One practical tip for Londoners is to look for "shoulder season" discounts. While June is busy, many contractors are looking to fill their books for late October or early November. If you can handle the stress of a late-season project, you might snag a 5% to 10% discount.

Be specific about the "tear-off." Some contractors might suggest shingling over your old roof to save money. Don't do it. It traps heat, voids many manufacturer warranties, and just kicks the problem down the road. You’ll pay more now to strip it to the deck, but you’ll save thousands in avoided rot repairs later.

Also, check for local rebates. While the federal Greener Homes Grant has evolved, some provincial or municipal programs occasionally offer incentives for "cool roofs" or high-efficiency attic insulation installed at the same time as the roof. Combining these jobs can save on setup and disposal fees. Finally, sourcing your own materials is rarely a good idea. Contractors get trade pricing at suppliers like Roofmart or ABC Supply on Exeter Road that you simply can't match at a big-box retail store.

Is 2026 a Good Time for Roof Replacement in London?

With an 8.5% year-over-year increase, the trend is clearly upward. Waiting until 2027 likely means paying an extra thousand dollars for the exact same roof. The market right now is busy, but it isn't the chaotic "supply chain crisis" we saw years ago. Materials are available, and crews are working.

If your shingles are curling or you’ve found granules in your gutters after a heavy spring thunderstorm, now is the time to act. The cost of plywood and lumber has stabilized, making the "worst-case scenario" repairs more predictable than they were two years ago. Get quotes now to lock in your pricing before the late-summer rush hits.

FAQ

How long does roof replacement take in London?

Most residential roofs in London take 1 to 3 days. A standard bungalow in a neighborhood like Ealing can often be done in a single long day. Larger homes in Westmount or those requiring significant structural repair might take closer to a week, especially if the June weather doesn't cooperate.

Do I need a permit for roof replacement in London?

For a standard "like-for-like" shingle replacement, the City of London typically does not require a building permit. However, if you are changing the structural framing, adding new dormers, or significantly changing the roof's pitch, you will need to file an application with the building department at City Hall.

Does the local weather affect which shingles I should buy?

Yes. London is in a high-moisture zone with significant freeze-thaw cycles. You should look for shingles with a high wind rating and an algae-resistance warranty (often called "StainGuard" or similar). Given our winter ice damming issues, ensure your contractor uses plenty of ice and water shield membrane along the eaves.
