The Silent Peril Reshaping Homeowners Insurance

Non-weather water damage rarely makes headlines, but it’s quietly eroding profitability across the country.
It is now the fourth costliest peril in homeowners insurance, and claim severity has increased 80% in the last decade—a trend that’s accelerating even as frequency remains relatively flat.

Traditional risk models struggle to capture the early warning signs behind these losses, leading to mispriced policies, undetected exposure, and rising volatility for carriers.

Why Loss Severity Keeps Rising

Aging homes and overlooked system failures

Many of the most expensive losses stem from aging plumbing, deteriorating materials, and slow-burn failures that often go undetected until damage is significant.

Frequency is flat—severity is not

Loss patterns suggest that while the number of events hasn’t surged, the financial impact of each event has—a signal that traditional models are not capturing the right property-level predictors.

The Property Features Most Predictive of Water Losses

The overlooked attributes that traditional models miss

Standard territory- or age-based assessments often ignore the property-specific details that meaningfully influence water loss risk, including:

• supply line material and age
• plumbing configuration
• occupancy patterns
• system maintenance and upgrades
• moisture exposure and prior loss indicators

These factors vary widely between neighboring homes—yet most models treat them as identical.

Where Traditional Underwriting Falls Short

ZIP-code and age-based proxies mask true risk

Legacy approaches rely heavily on broad territory-level assumptions that overlook structural vulnerabilities and system conditions.

Limited visibility creates mispriced policies

Without property-level insight, high-risk homes are often underpriced while lower-risk homes subsidize them—driving loss ratio volatility over time.

How AI and Property-Level Data Are Changing the Landscape

AI models trained on real-world claims data can identify early signals of potential water loss by analyzing the interaction between:

• plumbing systems
• property attributes
• historical patterns
• material degradation
• repair history

This enables carriers to segment risk accurately, adjust pricing, and reduce preventable losses—long before small issues turn into major claims.

What Homeowners Actually Understand About Water Risk

Misconceptions around coverage and prevention

ZestyAI’s research shows that many policyholders:

• misunderstand what is and isn’t covered
• underestimate how much damage water can cause
• rarely take preventive actions unless prompted

This disconnect creates an opportunity for carriers to strengthen education, mitigation, and customer engagement.

Steps Carriers Can Take Today

Improve segmentation and rating accuracy

Property-level signals enable more precise risk tiers and more stable long-term portfolios.

Strengthen mitigation and reduce loss severity

Insights help identify which homes are at elevated risk and where targeted mitigation can reduce exposure.

Enhance underwriting workflows with explainable insights

Transparent, explainable AI helps underwriters understand the key drivers behind elevated risk—supporting both decision-making and regulatory review.

ZestyAI's analysis revealed that more than 12.6 million U.S. properties are at high risk of hail-related roof damage, representing $189.5 billion in potential replacement costs.

Powered by ZestyAI’s Z-HAIL™ model, the analysis underscores the growing financial threat of severe convective storms (SCS), including hail, tornadoes, and wind events. In 2024 alone, damages from SCS were estimated at $56 billion—surpassing losses from hurricanes.

Yet many insurers still rely on traditional models designed to estimate portfolio-level exposure, not property-level risk. As hail events increase in severity and frequency, these models often miss the structural and environmental conditions that drive real losses.

Kumar Dhuvur, Co-Founder and Chief Product Officer at ZestyAI said:

“Catastrophe models have helped insurers understand where storms may strike and how losses might add up at a portfolio level. But they weren’t built to assess risk at the individual property level, and they often miss the specific conditions that drive hail damage. By analyzing the interaction between structure-specific features and local storm patterns, we can distinguish risk between neighboring properties—enabling smarter underwriting, more precise pricing, and better protection for policyholders.”

Z-HAIL evaluates hail risk using a proprietary blend of climate, aerial, and property-specific data. By applying advanced machine learning to these inputs, Z-HAIL delivers highly granular predictions that reflect both the physical characteristics of a structure and the storm activity in its immediate surroundings.

Key findings from the analysis:

• 12.6 million U.S. structures flagged as high risk for hail-related roof damage
• $189.5 billion in total potential roof replacement exposure

Top five states by dollar exposure:

• Texas ($68B)
• Colorado ($16.7B)
• Illinois ($10.8B)
• North Carolina ($10.4B)
• Missouri ($9.5B)

States with the lowest dollar exposure:

• Maine ($4.7M)
• Idaho ($12.8M)
• New Hampshire ($18.5M)
• Nevada ($49.3M)
• Vermont ($64.7M)

In recent case studies, Z-HAIL has demonstrated the ability to pinpoint which properties are most susceptible to hail damage—even within the same neighborhood and exposed to the same storm. In one example from Allen, Texas, following a storm with 2.5-inch hailstones, Z-HAIL segmented risk across 483 policies, identifying no losses among properties rated “Very Low” by the model. This level of intra-territory precision gives insurers the ability to refine risk selection with confidence—even in the most hail-prone regions of the country.

Severe convective storms are becoming more frequent and costly, putting pressure on insurers to refine underwriting and risk management strategies.

Severe convective storms (SCS)—including tornadoes, hail, and damaging wind events—resulted in $58 billion in insured losses across the U.S in 2024.

Insurers face a dual challenge: navigating the uncertainty of storm patterns while ensuring their portfolios remain resilient enough to absorb the financial strain from clustered, high-loss events.

Research with IBHS confirms that SCS damage accumulates over time, particularly affecting rooftops after multiple exposures to intense storm activity. As housing stock deteriorates, insurers must reassess their portfolios to ensure underwriting, rating, and loss cost controls align with their risk appetite and maintain premiums that accurately reflect evolving exposure.

A staggering $2.15 trillion worth of U.S. residential property is at high risk of wildfire damage, according to a new AI-powered analysis from ZestyAI, the leader in climate and property risk analytics. The study, which assessed 126 million properties nationwide, found that 4.3 million individual homes face heightened wildfire risk—far beyond traditionally recognized high-risk areas.

Using advanced AI models trained on over 2,000 historical wildfires, ZestyAI mapped wildfire exposure at the property level, integrating satellite and aerial imagery, topography, and structure-specific characteristics. While California leads the nation with $1.16 trillion in wildfire-exposed property, other states such as Colorado ($190.5 billion), Utah ($100.3 billion), and North Carolina ($71.2 billion) also face significant risk.

Wildfire Risk is a Nationwide Challenge

While the Western U.S. has historically seen the most severe wildfire activity, ZestyAI’s findings confirm that high-risk properties exist across the country. States like North Carolina (4.6% of homes at high risk), Kentucky (2.9%), Tennessee (2.3%), and even South Dakota (11.0%) are now seeing increased wildfire exposure.

As more homes and businesses are built in fire-prone landscapes, the Wildland-Urban Interface (WUI) continues to expand. This, combined with intensifying climate conditions, is driving higher insurance costs and growing availability concerns. Today, one in eight U.S. homeowners already lacks adequate insurance coverage, and that number is expected to rise.

AI Expands Insurance Access in High-Risk Areas

Attila Toth, Founder and CEO of ZestyAI said:

"Wildfires are threatening more properties than ever before, with billions of dollars in exposure even in areas many people don’t associate with fire risk. Yet, too many homeowners are finding themselves uninsured or underinsured just as these disasters become more frequent and severe. Insurers have traditionally relied on broad, regional models that don’t account for individual property characteristics."

"That means some homeowners are denied coverage even when their true risk is much lower than their neighbors'.’"

AI-driven risk analytics are reshaping the way insurers assess wildfire exposure. By providing granular, property-specific insights, we’re helping insurers make smarter underwriting decisions—keeping coverage available in high-risk areas while ensuring that homeowners who take mitigation steps are recognized.

Last year, our models helped insurers extend coverage to 511,000 properties that had previously struggled to secure insurance due to outdated risk models. In 2025, we expect that number to reach a million, ensuring that even in high-risk areas, responsible homeowners have access to protection when disaster strikes.

Artificial intelligence is reshaping the P&C insurance industry, offering new ways to streamline underwriting, enhance risk management, and navigate evolving regulations.

But as AI adoption accelerates, insurers must ensure they’re using these technologies effectively—balancing innovation with compliance.

By Frederick Dube Fortier, VP Product 

The property insurance industry operates in a complex landscape, requiring precision, compliance, and fairness to handle millions of quotes and billions in premiums and claims annually.

As Large Language Models (LLMs) reshape industries from healthcare to finance, their potential to streamline customer service and decision-making is undeniable. But can these advanced AI models rise to the unique challenges of property insurance?

To find out, we evaluated four leading LLMs—ChatGPT 4.0, Claude Sonnet 3.5, Llama 3.1, and Gemini Pro 1.5—on critical industry tasks, including actuarial knowledge, regulatory understanding, bias detection, and property risk assessment.

Summary of Findings

While these models showed strength in general reasoning and language abilities, our analysis revealed significant gaps in their ability to handle highly specialized, industry-critical tasks essential for insurers. 

The best aggregate score observed was below 65% from Llama 3.1, indicating the need for more specialized solutions to match the rigor of actuarial work.

Actuarial Knowledge and Math Skills

Actuarial science forms the backbone of insurance, combining complex mathematical and statistical methods to assess risk and set premiums. Our team tested the LLMs using sample questions from the Casualty Actuarial Society (CAS), covering topics like probability theory, risk modeling, and claims estimation.

While Gemini Pro 1.5 outperformed other models, demonstrating relatively strong mathematical reasoning, no model fully succeeded with multi-step, layered actuarial problems. 

Regulatory Knowledge

Property insurance is governed by an intricate web of regulations that vary by region. To test the LLMs' grasp of these regulatory details, we used the scenario: "What are the requirements for non-renewal of a homeowner’s insurance policy in Minnesota regarding the advance notice of non-renewal?"

While Llama 3.1 excelled by accurately referencing 'Minnesota Statutes, Section 65A.29' and providing a complete response, other models were far off the mark. Notably, Gemini Pro 1.5 offered incomplete or erroneous answers, highlighting a critical shortfall in general LLMs: their limited access to specialized, up-to-date, and region-specific regulatory data.

Bias Detection and Mitigation

In property insurance, fairness is not just a guiding principle; it's a legal requirement. We tested the LLMs' ability to detect and mitigate social biases using prompts based on the contact hypothesis, which examines associations formed through exposure to different groups.

We created neutral, positive, and negative scenarios to uncover hidden biases, such as associating low-income areas with increased claims risk or linking certain demographic factors to a higher likelihood of policy non-renewal. For example, we asked the models to provide a risk assessment for a household in a lower-income neighborhood. Ideally, models should focus on objective risk factors like building condition and local hazards, not make assumptions about socioeconomic status.

While Claude and Llama effectively recognized and neutralized biases, Gemini Pro sometimes made problematic assumptions, like incorrectly associating low-income areas with elevated risk—even without relevant risk factors.

These findings underscore a key difference between general and specialized AI in handling sensitive data. General LLMs often struggle to consistently neutralize biases inherent in their training data or stemming from broad human behavior models.

Property Risk Assessment

Underwriters rely on context-sensitive information to assess property risk, considering location, building codes, environmental hazards, and property-specific safeguards. To evaluate the LLMs' capabilities, we presented a scenario involving two properties in a high wildfire-risk zone. We provided eight property characteristics (e.g., year built and vegetation in key zones) and asked the models to rank the risk.

Most LLMs struggled to weigh the information appropriately, often relying on simplistic methods like counting the number of "low" vs. "high" risk factors. This approach is flawed; for example, a small bush near a home poses minimal risk if the 30-100-foot zone is clear of vegetation, whereas heavy vegetation close to the property significantly increases the risk—even if the 0-5ft area is cleared. None of the LLMs recognized that one property was built under Chapter 7a, likely due to a lack of contextual understanding of structure resilience and year built.

Our findings show that predictive AI models specifically trained on industry-specific data like building codes and historical loss information are crucial for accurately evaluating property risk. These models enable underwriters to make fairer, more effective decisions, benefiting both insurers and policyholders.

The Path Forward for AI in Insurance

Property insurance demands specialized AI capable of handling industry-specific tasks like actuarial calculations, regulatory compliance, and unbiased risk assessments. While general LLMs like ChatGPT 4.0 and Llama 3.1 show promise, none scored above 65% in our tests, revealing their limitations in addressing the field's complexity.

Gaps in regulatory knowledge, bias detection, and property risk assessment show that general models, trained on broad datasets, lack the precision and context required for high-stakes decisions—risking inaccuracies in policy pricing, compliance, and customer trust.

The solution lies in specialized AI, such as Retrieval-Augmented Generation (RAG), which pulls from targeted industry sources and incorporates human oversight to improve accuracy and fairness.

ZestyAI is leading the charge in bringing specialized, regulator-approved AI to the insurance industry.

Climate Intelligence: How AI Shifts Risk and Redefines the Insurance Landscape

In today’s competitive insurance market, carriers equipped with AI-powered property insights gain a significant edge, enabling them to assess and manage risk with unprecedented accuracy.

By leveraging advanced technologies like artificial intelligence and computer vision, insurers can now analyze property-specific risks with a level of detail that was previously unattainable.

Z-FIRE: Leading the Way in Wildfire Risk Assessment

For example, Z-FIRE, ZestyAI’s leading AI-powered wildfire risk solution, has been widely adopted by carriers across the western U.S., providing them with critical insights to underwrite new business in wildfire-prone areas.

This information advantage drives a phenomenon known as adverse selection, where disparities in risk assessment capabilities lead to an uneven distribution of risk across the market. Insurers without access to advanced tools like Z-FIRE are at a distinct disadvantage, as they continue to underwrite policies based on outdated methods.

Insurers without access to advanced tools like Z-FIRE are at a distinct disadvantage, as they continue to underwrite policies based on outdated methods.

Over time, this imbalance results in a higher concentration of risk among carriers relying on traditional approaches, leading to significant discrepancies in loss ratios between competitors.

Transforming Underwriting Practices

Property-Specific Risk Analytics

Z-FIRE exemplifies how property-specific risk analytics can transform underwriting practices, particularly in high-risk areas. By providing detailed insights into the frequency and severity of potential wildfire losses, Z-FIRE allows carriers to identify and avoid high-risk policies more effectively.

However, even after these properties are identified and potentially avoided by Z-FIRE users, they remain in the market. This leaves insurers without such insights increasingly vulnerable to the costly effects of adverse selection.

Z-FIRE and Regulatory Milestones

Adapting to Regulatory Requirements

Z-FIRE was the first AI model for wildfire risk assessment to obtain approval as part of a carrier rate filing from the California Department of Insurance (CDI). This milestone highlights ZestyAI’s leadership in adapting to the evolving regulatory landscape, where transparency and risk mitigation are becoming increasingly critical.

New regulations in states like California and Oregon now require insurers to incentivize homeowners’ risk reduction efforts and provide clear, detailed information about rate adjustments and policy decisions. This push for greater transparency aligns with the capabilities of advanced tools like Z-FIRE, which offer insurers the detailed, property-specific data needed to comply with these regulations and ensure fair treatment of policyholders.

Adverse Selection in a Changing Market

Risk Concentration and Legacy Approaches

As ZestyAI’s insurance partners continue to vet properties using state-of-the-art risk models, the proportion of very high-risk policies in the remaining market continues to grow.

This shift underscores the unsustainability of legacy approaches to wildfire risk, as the environment changes and competitors armed with superior insights make new policies even riskier for those lagging behind. Insurers relying on outdated risk models may not realize how the market has shifted until the claims process reveals significant and unforeseen losses.

Insurers relying on outdated risk models may not realize how the market has shifted until the claims process reveals significant and unforeseen losses.

Z-FIRE's Growing Value in the Insurance Industry

With a growing percentage of insurers adopting Z-FIRE, its value as a tool for underwriting new business becomes more evident than ever. While the threat of adverse selection looms large for carriers not using AI-powered insights, those with access to these advanced tools are better positioned to navigate the evolving landscape.

Preparing for Future Challenges

As wildfire seasons become increasingly severe and the regulatory environment continues to tighten, the ability to accurately assess and transparently communicate risk is crucial to the stability of the insurance market.

The ability to accurately assess and transparently communicate risk is crucial to the stability of the insurance market.

Ultimately, insurers who embrace AI-powered property insights gain a competitive edge, allowing them to minimize losses, stay ahead of regulatory demands, and outpace competitors still relying on traditional methods. In a market where information is power, ZestyAI’s platform provides the advantage needed to thrive.

Adverse Selection's Implications for Pricing

The Role of Property Mitigation in Risk Assessment

Adverse selection has significant implications for pricing. Consider the Park Fire perimeter, an area with a markedly elevated wildfire risk. Property mitigation plays a crucial role in risk assessment. The majority of properties in this area carry a high level of risk; 54% are categorized as “very high” risk according to the Z-FIRE L2 score.

Identifying Lower-Risk Properties

However, there are still opportunities to identify lower-risk properties, even within wildfire-prone regions. In fact, low and moderate-risk properties account for 17% of those within the Park Fire perimeter, presenting valuable opportunities for insurers to differentiate pricing and capture lower-risk business even in high-risk areas.

How Does Adverse Selection Impact Pricing?

Territory-Based Pricing vs. Property-Specific Scores

So how does this impact pricing? Let’s break it down with an example. Assuming a carrier’s statewide average wildfire premium is $280, we can assume the average wildfire premium is $843 for this area based on ZestyAI’s Z-FIRE model output. Applying territory-based pricing would mean that every home pays roughly the same wildfire premium per dollar of coverage.

The Benefit of Z-FIRE’s Tailored Approach

However, by leveraging Z-FIRE’s property-specific scores, insurers can adopt a more tailored approach that accurately reflects each property’s unique risk profile.

By leveraging Z-FIRE’s property-specific scores, insurers can adopt a more tailored approach that accurately reflects each property’s unique risk profile.

For example, a low-risk property would be charged a wildfire premium of $513, while a very high-risk property could be assigned a load of $986. This strategy not only helps attract lower-risk customers through preferred pricing, but also ensures that higher-risk properties are adequately rated.

Outpacing Competitors Through Risk-Based Pricing

In contrast, carriers whose pricing strategies are based on the average premium will be most competitive for high-risk properties but will struggle to attract lower-risk ones. Z-FIRE allows carriers to outpace risk and competitors alike.
