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

$28,500 CAD. That is what some London homeowners paid for a high-end roof replacement this year, particularly for those larger heritage homes in Woodfield or the sprawling estates in Sunningdale. While that number might cause a bit of sticker shock if you're a first-time renovator, don't panic just yet. The average London homeowner is actually spending $13,541 CAD for a standard roof replacement right now in August 2026. This represents a 5.0% increase over last year, reflecting the steady climb in material costs and the tight local labor market we've seen across Southwestern Ontario. Depending on your home's size and the materials you choose, you can expect a total project range between $7,000 and $28,500 CAD.

How Much Does Roof Replacement Cost in London?

If you are looking at a budget-friendly project, you are likely aiming for the $7,000 to $10,000 CAD range. This usually covers a straightforward asphalt shingle replacement on a smaller bungalow or a semi-detached home. In neighborhoods like Carling or Argyle, where many homes have simpler rooflines, these prices are more common.

A mid-range project, which sits at our average of $13,541 CAD, typically involves architectural shingles with a longer warranty, new underlayment, and perhaps replacing some damaged plywood decking. It also covers more complex roof shapes with multiple peaks or valleys.

At the high end - reaching toward that $28,500 CAD mark - you are looking at premium materials. This includes metal roofing, which has become a favorite for homeowners near the Thames River who want something that stands up to the dampness and heavy snow. High-end projects also factor in the specialized labor required for steep pitches or the intricate flashing needed around multiple dormers.

What Affects the Cost?

Figuring out why one quote is thousands more than another can feel like a headache. Here are the five main drivers for London roofers right now:

1. Material Choices: Asphalt shingles are the standard, but even within that category, prices vary. "Architectural" or "laminate" shingles cost more than basic 3-tab versions but last much longer. If you're looking at metal or composite slate, your material costs can triple.
2. Roof Pitch and Complexity: If your roof is so steep that workers need specialized safety harnesses and scaffolding, the labor price goes up. A "cut up" roof with lots of valleys, chimneys, and skylights takes significantly more time to waterproof correctly than a flat "up and over" roof.
3. Local Labor Market: London has a busy construction sector. With the ongoing expansion of the Fanshawe College area and new developments in the southwest, skilled roofers are in high demand. You aren't just paying for the shingles; you're paying for the expertise of crews who know how to handle Ontario's freeze-thaw cycles.
4. Permits and Waste: The City of London requires specific disposal methods for old shingles. Fees at the W12A Landfill on Manning Drive have shifted over the years, and your contractor builds these disposal costs into your quote. While a simple shingle-for-shingle swap doesn't always require a building permit, any structural changes to the roof rafters will.
5. Seasonal Timing: August 2026 is peak season. Everyone wants their roof done before the autumn rains and the heavy snow hits. Booking during this window often means paying a premium compared to a late-fall or early-spring slot.

How London Compares to Other Canadian Cities

London sits right in the middle of the pack for Ontario. Our average of $13,541 CAD is slightly higher than Barrie, where the average sits at $13,405 CAD. It is also notably more expensive than Oshawa, which averages $11,662 CAD. This is often due to London's specific mix of older housing stock that requires more intensive "tear-off" work compared to the newer, more uniform subdivisions in parts of the GTA.

Looking further west, Windsor is slightly more affordable at $13,048 CAD, likely due to a different local supply chain for materials coming across the border. However, if you were in Kelowna, you’d be looking at an average of $14,840 CAD, and St. John's jumps even higher to $15,490 CAD. London homeowners are actually in a relatively fair position compared to the national market, avoiding the extreme highs seen in coastal or mountain regions.

How to Save Money on Roof Replacement

You don't always have to pay the top-tier price to get a dry house. One of the best ways to save is to "overlay" shingles if your local building code and current roof condition allow it. This means putting new shingles over the old ones, saving thousands on labor and disposal. However, most London contractors advise against this because it can trap heat and shorten the life of the new roof.

Another tip is to time your project for the "shoulder season." While everyone calls roofers in August, asking for a quote for a late October or November start can sometimes land you a discount as companies look to fill their schedules before winter.

You can also save by handling the cleanup yourself. Ask the contractor for a discount if you manage the bin rental and magnetic sweeping of the yard. Finally, check with local suppliers like Copp’s Buildall to see if there are any overstock shingle colors. If you aren't picky about the exact shade of grey, you might find a deal on high-quality materials.

Is 2026 a Good Time for Roof Replacement in London?

With a 5.0% year-over-year increase, prices aren't dropping anytime soon. If your roof is showing signs of wear - like curling shingles or grit in the gutters - waiting until 2027 will likely only cost you more. The market right now is stable but expensive. Dealing with a leak in the middle of a February thaw is much more costly than a planned replacement in August. I recommend getting at least three quotes now to lock in current material prices before the next seasonal hike.

FAQ

How long does roof replacement take in London?

Most residential roofs in London take 1 to 3 days. A standard suburban home in Byron can usually be stripped and re-shingled in a single long day if the weather holds. Larger, more complex projects or those requiring structural repairs will take longer.

Do I need a permit for roof replacement in London?

If you are just replacing the "shingles" or the exterior membrane, you generally do not need a building permit from the City of London. However, if you are replacing the structural roof sheathing (the wood) or changing the roof's pitch, you must apply for a permit at City Hall.

What is the best roofing material for London's weather?

Architectural asphalt shingles are the most common because they handle the heavy snow and humidity well. However, metal roofing is gaining popularity in London because it sheds snow quickly and easily lasts 50 years, making it a "one and done" choice for many homeowners.
