Severe weather adaptations boost home value by up to 5.6% in Canada

As Canada faces more frequent floods, fires, and severe storms, homeowners are increasingly looking for ways to protect their properties. But climate‑resilient home upgrades aren’t just about protection, they’re starting to influence real estate values.  

A recent study by the Institute for Catastrophic Loss Reduction (ICLR) shows that features like hail‑proof shingles or a hail‑roof, backwater valves, and other resilience measures are becoming selling points in cities across the country.  

In places like Calgary, Edmonton, and Toronto, these upgrades are adding 2.8–5.6% to home prices—roughly $20,000–51,500 in additional value. These benefits often far exceed the cost of installation.

Most homeowners don’t realize these features add value and many listings fail to mention them at all.

Here’s what happens when home improvements against extreme weather are clearly named in real estate listings:

Up to $50,000 premium when resilience mentioned in property listings

A recent analysis of listings in Toronto, Calgary, and Edmonton by ICLR found five‑figure price lifts when adaptation features were clearly mentioned—consistent with what buyers say they’ll pay once they understand the value.

Here’s a breakdown of how much resiliency measures can increase a home’s value:

• Calgary: Listings that highlighted hail‑resistant roofing showed 2.9% higher asking prices, with the true effect likely between 0–6%. On a median price of $685,000, that’s about $20,000.
• Edmonton: Listings that mentioned flood‑resistant features were priced about 5.6% higher, adding an estimated $27,400 on a median detached home.
• Toronto: Homes that mentioned flood‑resilience features added 4.4% to the median home closing price of approximately $1.2 million, implying a best-estimate market value for flood protection over $50,000.  
• Calgary: Flood‑protection features were linked to a 2.8% increase in closing price, or about $19,500.

Most of these additions, such as sump pumps, backwater valves, or hail‑resistant shingles, typically cost between $3,000–10,000, according to the ICLR study. Homeowners could receive a return on investment for these installations prior to selling.

“I was surprised that there was evidence that resilience did affect property resale prices,” says Dan Sandink, senior director of resilience programs at ICLR in Toronto and co‑author of the study.

“And I was also surprised that there was even mention of resilience measures in real estate ads to begin with. But it’s a sign, a positive sign,” he adds.  

The researchers note that study findings are considered to be early signals rather than precise market-wide estimates. Some cities had only a handful of listings highlighting weather related installations, and in a few cases, only asking prices were available.

More than half Canadian homeowners would pay for upgrades if explained

Many homeowners say they face severe weather risks, but far fewer act on them. However, when people understand what resilience additions are, and what problems they prevent, interest rises quickly.

A Leger survey conducted for Rates.ca found that 56% of Canadian homeowners would be willing to pay more for a home with sump pumps with battery backup, stronger roof shingles, or better drainage. Another 20% said they hadn’t made up their minds, leaving room for demand to grow with clearer information.

Among those willing to pay more, spending thresholds were substantial: 

• 26% would pay up to $5,000 more
• 20% would pay $5,000–10,000 more
• 6% would pay $10,000 or more, including 4% willing to spend $20,000+

The survey was conducted March 6–9, 2026, and polled 1,073 homeowners across Canada.

The findings point to a clear gap. While 86% of homeowners believe homes face extreme weather risks, three in five (59%) say they have not installed, and do not plan to add, any protective measures. The issue isn’t indifference, it’s clarity. Buyers often don’t know what protective measures and rebates are available, what they do, or why it matters.

Flooding tops the list of perceived threats nationwide, followed by high winds, wildfire, heavy rain, and hail. When homeowners can connect a familiar risk to a specific fix, they’re more open to paying for it. Hence price premiums show up once those features are built into homes and clearly explained.

Why awareness flips to action

Willingness to invest in upgrades is shaped by how people perceive their own risk exposure—and most underestimate it. As Sandink notes, “Most homeowners have no idea what the technical components of their building are. They usually assume flood protection is already covered through government requirements.”

Public awareness often lags reality. “Even in high‑risk flood‑prone areas, we know that 90% of people don’t know they’re exposed to flooding, if they’re in a floodplain,” Sandink says.  

This gap explains why resilient homes command a premium in some markets. In other areas, buyers overlook renovations because they don’t recognize risks those features address.

After a disaster, public attention to risks grows. Coverage issues are discussed more openly and agents report buyers scrutinizing protective features. The ICLR researcher points to Calgary listings that highlight Class‑4 hail‑resistant roofs after major storms.  

When risks are local and immediate, protective home measures are perceived as worth the costs.

What home improvements do buyers recognize in high‑risk markets?  

Here are features that appeared most often in listings tied to price premiums or prioritized by buyers once risks were explained, according to the ICLR study:

Hail (Calgary and the Prairies): 
Homes with Class 4 shingles stood out. These are impact‑resistant roofing materials designed to take a beating from large hail without cracking or tearing. Paired with hail‑resistant siding, they reduce the chance of costly roof repairs after major storms.

Flood (Toronto, Edmonton, Halifax): 
Features that make a flood‑resistant house were a major draw. Buyers responded strongly to backwater valves, which stop sewage from backing up into basements during heavy rain, and sump pumps with battery backups that keep water moving out even if the power goes out. Listings that also flagged drainage improvements or basement waterproofing tended to perform better, especially in areas with a history of basement flooding.

High wind (GTA and Atlantic Canada): 
In wind‑exposed regions, attention shifted to how firmly a house is held together. Features like reinforced roof‑to‑wall connections, upgraded nailing patterns, and shingles rated for high winds helped signal that a home was less likely to lose shingles, or its roof, during major wind events.

Wildfire (B.C. Interior and Alberta): 
In wildfire zones, buyers prioritized homes built to resist fire spreading. Fire‑resistant roofing and siding, vents designed to keep embers out, and cleared space around the house all reduced the risk of ignition. These improvements increasingly factored into buyer decisions as wildfire seasons grow longer and more intense.

Listings rarely name these improvements—leaving value on the table

The study shows that adaptation features can boost a home’s value, but you wouldn’t always know it from the way listings are written.  

Mortgage broker and Rates.ca expert Victor Tran says real estate agents tend to spotlight whatever photographs best, new kitchens, updated bathrooms, while the most important improvements often sit behind the walls.

“Agents highlight what’s visible,” he says. “Mechanical upgrades or resilience features are just as important, but buyers don’t usually see them. They’re the backbone of a house.”

Still, in neighbourhoods with a history of basement flooding, Tran says buyers appreciate when agents mention backwater valves, sump pumps, better drainage, or newer mechanicals in property listings.  

“Knowing a homeowner has taken preventative measures is reassuring,” he says. “It’s something buyers feel they won’t have to worry about.”

ICLR’s research shows that when resilience features are clearly mentioned in a listing, homes tend to sell for more. Even small cues in the listing description can signal to buyers that the home is better protected over the long run.

So why aren’t these features highlighted more often? Tran says it mostly comes down to awareness. “There’s definitely a lack of understanding, not just among buyers, but even among real estate agents and mortgage brokers,” he says. “We’re not experts in these things.”

That gap mirrors what researchers are seeing nationally: most homeowners underestimate their risk unless they’ve lived through an unfortunate situation. But interest in these preventative measures jumps with improved awareness of strategies to mitigate such risks. Listing agents who don’t mention these additional features may be leaving money on the table.

How to turn invisible home improvements into documented value

If you’re planning to invest in severe weather mitigation or getting ready to sell, here’s how to translate installation dollars into real value, according to the ICLR study and the experts:

1) Package your proof 
Create a simple file with invoices (showing install dates and models), any permits, and a short explanation about each new protection measure. Add relevant pages from a pre‑listing inspection. This turns “invisible” work into something buyers can verify quickly.

2) Add reasons for installations in listings 
Ask your agent to name the home improvement and anchor it to local conditions in one clear line, e.g., “Class 4 roof (2022), upgraded after recent hail events,” or “Backwater valve + sump (2021) due to neighbourhood flooding”. Put it in the bullets, not buried in paragraph three.

3) Use photos and captions 
Include a close‑up of the installed mitigation with a short caption (label the roof shingle bundle, valve location, sump with battery backup). A single photo can do more than a paragraph of copy.

4) Time your messaging 
If your area recently had a major event, lead with resilience details in the first sentence of the home description and in your social posts. Attention to these features is highest right after local headlines.

5) Talk to your insurer before you list 
Ask how your preventative measures are recognized (not just on premium, also deductibles, sub‑limits, eligibility). Get the exact wording insurers use and keep it in your proof file. If appropriate, add “eligible for insurer incentives (buyer to verify)” in remarks.

ICLR’s research points to a market that’s already shifting. Severe weather protection, once treated as invisible, technical add‑ons, are increasingly showing up in what buyers value and what homes sell for.  

The surprising part isn’t that these upgrades protect properties; it’s that they’re now beginning to influence price in measurable ways. The gap, for now, is awareness: most homeowners don’t realize these features boost value, and many listings leave them out entirely.
