Inflation, replacement costs, climate losses shape homeowners’ insurance options

A person's hands are arched over a small model of a home that is placed on top of an insurance contract.

The homeowners insurance market is catching up to its cost drivers while still facing challenges to affordability and availability. Rates continue to climb as natural disasters intensify and replacement costs rise, but industry analysts expect meaningful improvement over the next two years. A new Triple-I Issues Brief provides a snapshot of the market’s performance and outlook, and discusses how some trends are shaping its future.

The latest results for the product line have helped narrow the anticipated 2025 gap between the performance of the personal and commercial lines. Despite a volatile start to 2025 driven largely by January’s destructive Los Angeles wildfires, homeowners insurance is still headed for double-digit net written premium growth this year.

With ​​nearly half of all homes in the United States at risk of “severe or extreme” damage from weather related events, climate risk looms large. In January 2025, the U.S. Department of the Treasury released “Analyses of U.S. Homeowners Insurance Markets, 2018-2022: Climate-Related Risks and Other Factors.“ a report based on the most comprehensive and granular snapshot of the homeowners insurance market to date. The agency found that climate risk is making it more costly for insurers to operate, as insurers’ costs in 2018-2022 were higher in areas with the highest expected losses from climate-related perils. The paid loss ratio, which reflects how much insurers paid for claims relative to the premiums they collected, was highest in the highest-risk ZIP Codes.

In 2025, the U.S. experienced its first hurricane season without a single landfall in a decade. However, the Triple-I issue brief explains, while 2025 economic losses from natural catastrophes are running below recent averages, other perils — such as severe convective storms, wildfires, and flash flooding — are becoming formidable sources of insurer loss. These increasingly frequent moderate disasters are challenging traditional catastrophe models built around infrequent peak perils, such as major hurricanes.

At the same time, soaring replacement costs have become the new normal for the homeowners market. Repair and rebuilding expenses have jumped nearly 30 percent over the past five years, fueled by inflation, supply-chain disruptions, rising construction material prices, labor shortages, and, more recently, new federal tariffs. Although the full impact of these tariffs has been milder than expected so far, the worst effects may simply be deferred until 2026 as inventories decline. Rising replacement costs translate directly into higher claim payouts, placing additional pressure on insurers and, ultimately, policyholders.

Beyond tariffs, other political and regulatory shifts are adding a new uncertainty as federal disinvestment in climate monitoring and mitigation may impede the insurance industry’s ability to accurately price risk, predict future losses, and, ultimately, provide affordable coverage. Meanwhile, several states grapple with balancing affordability with the stability and solvency of their insurance markets.

Insurance pricing must reflect these increased risks to maintain policyholder surplus, the funds regulators require insurers to keep on hand to pay claims. If premium rates fail to reflect increased costs, insurers may rapidly drain their policyholder surplus. This issue brief discusses how emerging technologies, such as advanced predictive analytics, aerial imagery, and smart-home sensors, could pave the way for more accurate pricing, faster claims processing, and improved risk prevention.

An Insurance Research Council (IRC) study indicates that homeowners familiar with some AI-driven insurance solutions view pricing using those technologies as fairer and express fewer concerns overall. These tools may play a critical role in bolstering affordability, rebuilding trust, and strengthening the resilience of the homeowners’ insurance sector amid escalating climate and economic pressures.

The issue brief’s list of factors and trends impacting the homeowners’ market isn’t intended to be exhaustive. Accordingly, future briefs on homeowners (or property lines in general) may highlight other pertinent topics, such as the link between insurance premiums and property prices. While home values in high-risk areas can often be diminished by rising premiums, higher home values can generally mean higher replacement costs, and consequently, lead to higher premiums. As of early 2025, home prices are up 60 percent nationwide since 2019 and still rising by 3.9 percent YoY, according to the Joint Center for Housing Studies at Harvard University. The Harvard report cites Freddie Mac data indicating home insurance premiums jumped 57 percent from 2019 to 2024.

Storm-Resistant Roof Efforts Gain Ground

By Lewis Nibbelin, Research Writer, Triple-I

Severe convective storms cost insurers an estimated $46 billion in the first three quarters of 2025, Gallagher Re has reported, marking the third straight year of U.S. claims from these events through September exceeding $40 billion. Total losses from these storms – which include tornadoes, hail, straight-line winds, and drenching thunderstorms – reflect growing impacts from inland flooding and, in particular, the vulnerability of roofs to damage from these storms.

Approximately 70 to 90 percent of total insured residential catastrophic losses arise from roof-related damage, according to Insurance Institute for Business & Home Safety (IBHS) estimates. Though poorly maintained roofs contribute to this finding, outdated building codes exacerbate the risk, leading insurance industry leaders to advocate for widespread adoption of FORTIFIED roof standards.

Developed by IBHS, FORTIFIED standards can reduce severe weather damage in new or retrofitted homes through construction methods like sealing roof decks and anchoring roofs to wall framing using stronger nails. While such standards remain voluntary, Louisiana has modelled the proactive approach needed to facilitate adoption with the recent expansion of its Louisiana Fortify Homes Program, which began offering homeowners thousand-dollar grants to retrofit their houses along these guidelines in 2023, incentivizing roughly 40 percent of the now 10,000 FORTIFIED roofs in the state.

“FORTIFIED roofs are the long-term solution for affordable insurance in South Louisiana,” said state insurance commissioner Tim Temple, noting that his office aims to implement bigger and more standardized insurance discounts for FORTIFIED homeowners to reinforce the state’s already improved insurance rates.

An emerging trend

Though Louisiana became the “fastest-growing state” to adopt FORTIFIED standards, Alabama pioneered incentivizing them through its own Strengthen Alabama Homes program, financed by the insurance industry with more than $86 million in grants since 2016. Designed to enhance community resiliency while also lowering insurance rates, completed retrofits qualify residents for premium discounts ranging from 25 to 55 percent.

A May 2025 study from the Alabama Department of Insurance, in collaboration with the University of Alabama Center for Insurance Information and Research, showcases the program’s success, highlighting that FORTIFIED homes suffered less property damage and fewer insurance claims than homes built using other construction methods when Hurricane Sally made landfall in the state.

“The Center’s Hurricane Sally report doesn’t just quantify the effectiveness of the FORTIFIED program, it clearly demonstrates that homes can be built to survive storms, making them eminently more insurable,” said IBHS CEO Roy Wright. “This report should be a clarion call to communities across the country, urging them to implement Alabama’s multipronged approach to promoting disaster mitigation.”

Insurers answered the call in Oklahoma, North Carolina, and South Carolina, all of which boast similar programs backed by the insurance sector and accompanying premium reductions. Mississippi nearly joined their ranks before state funding for the grant program was suspended earlier this year, though insurance discounts remain available. States such as Florida, Georgia, and Minnesota also offer comprehensive insurance discounts for FORTIFIED properties, with the latter poised to fully replicate a grant program in response to mounting hailstorms.

Addressing cost concerns

While 75 percent of homeowners express willingness to invest in weather-resistant features, only 18 percent have reinforced or replaced their roofs with those materials, a recent Nationwide survey reveals. Grants help lower the cost of entry to FORTIFIED roofs for many homeowners, but it is worth noting the relative affordability of such upgrades, which can cost as little as $500 for a 2,000 sq. ft. home.

Describing the benefits of FORTIFIED standards as “measurable and increasingly essential,” Nationwide Property & Casualty president and COO Mark Berven emphasized the crucial role insurance agents play in raising consumer awareness of these risk reductions and their broad accessibility.

“Our industry needs to remind homeowners they have control in the face of severe weather events,” Berven wrote. “By investing in resilience, they can take an active role in protecting their homes, their valuables and their memories – giving them the peace of mind they’re looking for.”

Triple-I Chief Economist Testifies on NYC Measure On Short-Term Rentals

By Loretta Worters, Vice President – Media Relations, Triple-I

Triple-I Chief Economist and Data Scientist Dr. Michel Léonard provided insurance insight to the New York City Council’s Committee on Housing and Buildings as they consider Local Bills 948-A and 1107-A. The measures aim to address New York City’s housing-affordability challenges by expanding homeowners’ ability to earn income through short-term rentals.

Léonard’s testimony focused on helping policymakers understand the protection gaps that can arise when residential dwellings are used for commercial purposes. He began by emphasizing Triple-I’s role as a nonprofit research and education organization, not a lobbying entity.

Many homeowners, Léonard noted, are unaware that standard homeowners’ policies generally exclude commercial activity, meaning hosts who fail to update their coverage may face denied claims, inadequate liability protection, or higher out-of-pocket costs if a loss occurs. Because short-term rentals fall under commercial use, homeowners who rent out their homes — whether occasionally or regularly — may inadvertently operate without appropriate coverage.

Operating a short-term rental typically requires:

  • Notifying their insurer,
  • Adhering to policy terms, and
  • Obtaining short-term rental-specific or commercial coverage.

Committee Chair Pierina Ana Sanchez asked what the cost impact might be for homeowners who must shift to a commercial policy. Léonard explained that, while costs vary, the more pressing issue is that many homeowners are unaware they have gaps in coverage.

This means homeowners, renters, and residents could all face significant financial or liability risks if an incident occurs. These risks are especially complex in multi-unit buildings, where short-term rental activity can affect both an individual unit’s policy and the building’s master policy—potentially increasing premiums and liability exposure for all residents. The result can be large uncovered losses, disputes, or claims that ripple throughout buildings and neighborhoods.

Homeowners insurance in New York City is significantly different from New York State. In written testimony to the New York Senate Committees on Investigations and Government Operations, Insurance, and Housing, Construction, and Community Development on Tuesday, November 18, Triple-I Chief Insurance Officer Patrick Schmid cited data from the Insurance Research Council (IRC), saying New York ranks 29th in its homeowners’ affordability study, with a 2.11 percent ratio of homeowners’ insurance expenditure to median household income. This is a lower percentage than a decade earlier for the state. According to IRC, New York’s homeowners’ insurance expenditures equal 0.39 percent of median.

Insurance in New York City is complicated, influenced by high property values, dense construction, and a challenging legal and claims environment. Rising labor and construction costs also contribute to higher premiums and more severe claims.

Coverage gaps and denied claims, even when policies are applied correctly, can lead to public misunderstandings about insurance. As Allstate CEO Tom Wilson recently noted, trust between consumers and companies is at a “tipping point” and must be reinforced through reliability and clear communication.

With its independent insight, Triple-I gave policymakers a clear understanding of the potential insurance consequences of expanding short-term rentals in residential buildings, helping them make informed decisions that balance affordability, consumer protection, and risk management.

Chart of the Week 11 18 2025: Native Americans Face Heightened Extreme Weather Risks

As part of an ongoing discussion on the link between the housing and insurance markets, the Insurance Information Institute (Triple-I) released a Chart of the Week (COTW) that provides a snapshot of climate risk concerns for American Indian and Alaska Native (AIAN) population.

The provided estimate for the number of Native Americans in the U.S. is 7.1 million – about 2.1 percent of the total population. As much as 95 percent of the general U.S. population lives in a county that has experienced a natural disaster since 2011. However, this COTW says at least 50.9 percent of Native Americans live in states facing heightened risks from wildfires, floods, tornadoes, and droughts. The chart also reveals that Indigenous people in the U.S. face higher death rates from extreme weather events than the total national population, at 0.6 per 100,000 compared to 0.2 per 100,000.

Native communities are situated on the front line of climate risk.

As insurance is designed to help policyholders and their communities recover from insurable events, coverage availability and affordability can contribute to resilience. However, states that are home to at least half of the U.S. Native American population rank high on the Insurance Research Council (IRC) report, Homeowners Insurance Expenditures as a Percent of Median Household Income – Oklahoma (4th), Arizona (5th), Texas, (6th), New Mexico (14th), California (25th) – indicating comparatively less coverage affordability in those states. While availability and affordability can ultimately be driven by a mix of key underlying cost drivers, climate risk and home-ownership challenges can play a crucial role in access for many Native American homeowners.

Extreme weather events, such as hurricanes and typhoons, have shaped the way colonization of North America unfolded, beginning in the early centuries of European contact. For thousands of years prior, Native Americans had thrived in their homelands by taking measures to survive long-term severe weather, such as seasonally migrating away from flood-prone areas or building nature-based infrastructure as needed. Colonial expansion, in which Indigenous people lost nearly 99 percent of their historical land base over time, decimated Indigenous populations and pushed survivors into high-severe-weather-risk areas or lands, in many cases previously unknown to their respective tribal groups.

As a result of centuries of these forced removal policies and government-directed or sanctioned land dispossession, present-day Native American lands “are also generally far from historical lands, averaging a distance of roughly 150 miles” and are often in inherently more climate risk-prone areas today – i.e., low-lying, exposed, less habitable due to drought, etc. Living today on the front lines of climate risk across the U.S. means frequently experiencing acute effects, such as thawing permafrost, rising sea levels, increased flooding, stronger storms, erosion, and shifting ecosystems.

For instance, a 2024 study indicates that Oklahoma, home to 39 federally recognized tribal nations, “faces climate and demographic changes that disproportionately put many Native Americans at risk. The heavy rainfall, 2-year floods, and flash floods are all projected to have increased risks by 501.1 percent, 632.6 percent, and 296.4 percent, respectively.”

In a village in western Alaska, where permafrost is thawing, buildings (including a preschool) are shifting, water intrusion is increasing, and relocation is becoming a real threat. Recently, nearly 50 Alaska Native communities experienced “towering wind speeds, record storm surge, and widespread flooding”, resulting in at least one death and the displacement of 1,500 people. Initial estimates have reported that the storm decimated 90 percent of homes in the coastal village of Kipnuk and 35 percent in Kwigillingok, “which has also experienced toxic chemicals spilling into its freshwater supply.”

Climate risk can threaten lives and property, of course, but also regional economies, one of the key ingredients in building capacity for resilience. For example, a study of climate-driven economic challenges posed to Navajo Nation, the largest Indian reservation in the U.S., shows that “drought has a larger impact on cattle production than hay production, resulting in total economic losses of $8.2 million and $0.4 million for the cattle and hay sectors, respectively.” Without robust regional economies, infrastructure, or policy support, Native American homeowners and their communities may struggle to adapt or relocate effectively.

Homeownership costs may contribute to the protection gap.

Native American homeowners are more likely to lack coverage if they:

  • Are homeowners living in New Mexico and certain rural areas of Texas
  • have manufactured homes, or
  • own inherited homes.

Data collected through the Home Mortgage Disclosure Act (HMDA) reveals that Native Americans, on average, pay more to finance their homes – in some contexts up to two times more. While that disparity can be attributed to several factors, one major driver is the loan type that appears to be more common among Native borrowers, home-only loans. “Nearly 40 percent of loans to Native American borrowers on reservations were for manufactured homes, compared to 3 percent of loans to White borrowers”. Further, about 8 out of 10 manufactured-home loans were home-only loans.

Home-only loans, a financing tool used for movable personal property in which the lender retains ownership of the property until the borrower fully pays the loan, can make financial sense in some instances. Nonetheless, borrowers typically pay higher interest rates and have fewer consumer protections, such as federal guarantees, than regular mortgages. The pressure of these circumstances may compel the homeowners to carry insufficient coverage, or, when they pay off the loan, none at all.

Federal funding freezes can impede resilience.

Data from the National Congress of American Indians show that “U.S. citizens receive, on average, about $26 per person, per year, from the federal government, while tribal citizens receive approximately $3 per person, per year.”  Recent federal disinvestment in 2025 from crucial risk prevention and management programs and other supportive infrastructure –  including public radio stations which can be used for advance severe weather warnings and coordination of disaster recovery efforts – has exacerbated the burden from longstanding disparities. This decrease in support can also heighten the need for insurance coverage and closing the protection gap.

Amy Cole-Smith, Executive Director for BIIC/ Director of Diversity at The Institutes says, “the numbers are clear: Native Americans face higher exposure to extreme weather, higher insurance burdens, and higher rates of being uninsured. These factors reflect not just climate trends but historical inequities that continue to shape outcomes today. Strengthening coverage access is essential to protecting lives, homes, and cultural continuity.”

As Smith has often expressed, one way the industry can start closing the protection gap is “by having people at the table who understand the lived experiences behind the numbers.”

IRC: Homeowners’ Insurance Rate Filing Growing Less Efficient

By William Nibbelin, Senior Research Actuary, Triple-I

The rate-filing process for homeowners’ insurance has become less efficient and effective, a new study by the Insurance Research Council (IRC) shows.

The report – Rate Regulation in Homeowners Insurance: A Comparison of State Systems analyzed industry data from 2010 through 2024 across all states, including the District of Columbia. The study found that, not only is it taking longer for insurers to get rate increases approved, but the increases are lower than requested, with bigger gaps between the request and the granted amount than had previously been the case.

Key findings:

  • The number of rate filings is growing at a compound annual growth rate of 3.3 percent from 2018 to 2024 nationwide.
  • The average number of days to approval grew from 44 to 63 days.
  • The number of filings withdrawn increased from 2.9 percent of filings to 3.9 percent of filings.
  • The percentage of filings receiving less rate impact than requested grew by more than 10 points.
  • The disparity in approved rate impact grew by nearly 1 point.
  • Market concentration (as measured by the Herfindahl-Hirschman Index, or HHI) decreased by 14.6 percent.
  • The residual share of direct written premium has grown at a compound annual growth rate of 10.5 percent from 2020 to 2024
  • A strong-to-moderate correlation exists between net underwriting losses and premium shortfalls within states and across time.
  • Filing process measures and market outcomes vary by regulatory systems.

During this same period from 2010 through 2024, the homeowners’ insurance industry experienced a net combined ratio over 100 in 10 of the 15 years. Combined ratio – calculated as losses and expenses divided by earned premium plus operating expenses divided by written premium – is a key measure of underwriting profitability. A combined ratio over 100 represents an underwriting loss.

The IRC report includes the determination of a strong correlation between underwriting loss and premium shortfalls, defined as the potential dollar difference between the effective filed rate impact and approved rate impact.

In California, for example, the time to approval exceeds that of the next highest state – New York – by more than four months. California also has the second-fastest-growing residual market share from 2.1 percent in 2019 to 8.2 percent in 2024 and the second-fastest-growing excess and surplus homeowners market share from 0.3 percent in 2010 to 6.3 percent in 2024. This means that, at most, only 85 percent of California homeowners’ insurance is covered by a standard policy.

Illinois Lawmakers
Reject Risk-Based
Pricing Challenge

By Lewis Nibbelin, Research Writer, Triple-I 

Illinois insurers narrowly avoided increased government involvement in insurance pricing as state legislators rejected “an extreme prior-approval system found nowhere else in the country,” according to a joint statement from the American Property Casualty Insurance Association, the National Association of Mutual Insurance Companies, and the Illinois Insurance Association.

If approved, the bill would have given regulators the authority to block rate change and order refunds from insurers for premiums deemed excessive, effectively generating “fewer choices and greater instability,” the statement continued.

While calls for the bill began in July, following homeowners’ insurance rate hikes, Illinois has a history of legislative challenges to actuarially sound pricing. Similar legislation in Louisiana passed that same month, amid record rate filing rejections in Pennsylvania and two California lawsuits accusing insurers of deliberately underinsuring policyholders to maximize profits.

Such trends underscore pervasive misunderstandings surrounding risk-based pricing, the practice under which insurers offer different prices for the same coverage based on risk factors specific to the insured. Without it, insurers could not adequately cover mounting natural catastrophe losses, inflationary pressures, and other rising costs, leading to an insufficient policyholder surplus to pay claims. When surplus falls below a certain threshold, insurers must raise premium rates, adjust their coverage availability, or, in extreme cases, become insolvent.

Under this pricing methodology, Illinois benefits from better coverage affordability compared to the national average and a competitive insurance market of more than 200 operating insurers.

“Illinois has a very stable insurance marketplace,” said Triple-I CEO Sean Kevelighan. “Restrictive legislation could lead to a California-like regulatory environment that would impact insurance affordability and availability in the state, rather than help consumers as intended.”

Rather than involve themselves in the complexity of insurance pricing, policymakers in Illinois and elsewhere would do a greater service to their constituents by exploring and investing in risk reduction through cost-saving mitigation and resilience investments. The property/casualty insurance industry can be a valuable partner in such beneficial approaches.

California Insurance Market at a Critical Juncture

Despite Headwinds,
P/C Insurance Industry Maintains Course in 2025

By William Nibbelin, Senior Research Actuary, Triple-I

The U.S. property/casualty (P/C) insurance industry is on track for a second consecutive year of underwriting profitability in 2025, and is projected to grow faster than the broader U.S. economy, according to the latest Insurance Economics and Underwriting Projections: A Forward View report from Triple-I and Milliman. The report, which is based on data through the first half of 2025, highlights continued progress despite persistent geopolitical and natural catastrophe uncertainties.

Positive Economic Signals and Lingering Concerns

The industry’s economic outlook remains cautiously optimistic. According to Michel Léonard, Ph.D., CBE, chief economist and data scientist at Triple-I, the industry has benefited from stronger-than-expected underlying growth. He also noted that P/C replacement costs continue to rise more slowly than overall inflation.

However, Léonard also pointed to factors that make the outlook for 2026 especially important to watch.

 “Ongoing risks, including tariffs, labor market softening and persistent inflation,” could pose challenges, he said. While the impact of tariffs has been less severe than initially anticipated, their long-term effect remains an open question.

Underwriting Performance: A Mixed Bag

Overall underwriting profitability for 2025 is expected to be a repeat of 2024, but to a lesser degree. The performance gap between personal lines and commercial lines is narrowing.  

“Favorable second-quarter results for homeowners helped narrow the anticipated 2025 gap between personal and commercial lines performance created by the Los Angeles fires in the first quarter,” said Patrick Schmid, Ph.D., Triple-I’s chief insurance officer.

Schmid also noted that personal lines premium growth is expected to remain higher than commercial lines by one point in 2025. That difference is projected to disappear by 2027.

Personal Lines

  • Personal Auto: The personal auto sector continues to be a highlight, with its forecast 2025 Net Combined Ratio (NCR) on track for continued profitability. The forecast has also slightly improved from prior estimates.
  • Homeowners: Despite favorable results in the second quarter, the homeowners’ NCR forecast for 2025 is still expected to be unprofitable for the year.

Commercial Lines

  • General Liability: This continues to be a line of concern. According to Jason B. Kurtz, FCAS, MAAA, a principal and consulting actuary at Milliman, “We see underwriting losses continuing in 2025, with the 2025 net combined ratio for GL forecast at 107.1.” He also said that, while slight improvement is expected in 2026-2027, “we estimate GL combined ratios to remain above 100.” Kurtz added, “Direct incurred loss ratios through mid-2025 have not improved relative to 2024’s poor result. Forecasted net written premium growth of 8.0 percent is 4.8 points above 2024 as premiums respond to recent performance.”
  • Workers Compensation: In contrast to general liability, workers’ compensation remains the strongest-performing major line in the P/C industry. Preliminary 2025 results from NCCI show calendar year combined ratios in the range of 85–93 percent. Donna Glenn, Chief Actuary at NCCI, noted, “If this holds, it will represent 12 consecutive years of combined ratios under 100% for private carriers.” For more details on the preliminary Workers Comp 2025 results, see NCCI’s full analysis in 2025 in Sight, 2024 in Review: The Latest Results for Workers Compensation.

Delving Deeper: A Members-Only View

For members who want to dig deeper into the projections, the full Insurance Economics and Underwriting Projections: A Forward View report offers a more granular analysis, including:

  • A detailed look at personal auto and commercial auto results, breaking down the quarterly experience between auto liability and physical damage.
  • A forecast of net combined ratio and net written premium growth specific to farmowners insurance.
  • A comparison of commercial property sub-lines.
  • A breakdown of commercial multiple peril results, differentiating between property and liability performance.

The next quarterly report will be presented at a members-only webinar in January 2026.

Study Supports Defensible Space, Home Hardening as Wildfire Resilience Tools

A recent paper published in Nature that  analyzes five major California wildfires confirms what insurers, fire scientists, and risk modelers have long asserted: Defensible space and home hardening help mitigate wildfire risk and improve resilience.

The study found that clearing vegetation and flammable materials within 1.5 meters of a structure — an area known as “Zone 0” — is one of the most effective actions a homeowner can take. When this is paired with home-hardening features like non-combustible siding, enclosed eaves, and vent screens, the results are staggering: predicted losses dropped by as much as 48 percent, according to the study.

Homes built after 1997, when California adopted stricter building codes, consistently outperformed older structures. These newer homes incorporated fire-resistant materials and design features that significantly improved survival rates.

From an insurance perspective, such steps – by leading to reduced losses and fewer, less-costly claims – can alleviate some of the upward pressure on premium rates in areas at higher risk for wildfire. In the long term, they can improve insurance affordability and availability in fire-vulnerable geographies.

Wildfire risk is strongly conditioned by geographic considerations that vary widely across and within states. A recent paper by Triple-I and Guidewire – a provider of software solutions to the insurance industry – used case studies from three California areas with very different geographic and demographic characteristics to go deeper into how such tools can be used to identify properties with attractive risk properties, despite their location in wildfire-prone areas. The use of such data-driven analysis can help insurers identify less risky properties within higher-risk geographies. 

The study in Nature examined five major fires from recent history in the wildland-urban interface (WUI) – Tubbs (2017), Thomas (2017), Camp (2018), Kincade (2019), and Glass (2020) – using machine learning to analyze on-the-ground post-fire data collection, remotely sensed data, and fire reconstruction modeling to assess patterns of loss and mitigation effectiveness.

Using a tool called an XGBoost classifier, the study found that “structure survivability can be predicted to 82 percent.” The study reported that “spacing between structures is a critical factor influencing fire risk…while fire exposure, the ignition resistance (hardening) of structures, and clearing around structures (defensible space) work in combination” to mitigate that risk.

“With the science-based information from this report, we can reduce risk and make our communities safer from wildfire,” said Janet Ruiz, Triple-I’s California-based director of strategic communication.  Accuracy of 82 percent on predictability of structures burning is a major improvement, and mitigation is the key.”

Coordinated community-wide strategies like vegetation management, building code enforcement, and distance between structures are essential. Triple-I and its members and partners are working to inform, educate, and drive behavioral change to reduce risk and build resilience.

Can a Fire-Prevention Device Be a “Gateway Drug” to Home Resilience?

By Lewis Nibbelin, Contributing Writer, Triple-I

Tying a fire-prevention IoT device to the distribution networks of major insurers may have cracked the code for modifying human behavior toward risk prediction and prevention, says the CEO of Whisker Labs, the producer of Ting.

Ting helps protect homes from electrical fires by using AI to detect arcing – the precursor to most electrical fires. Once connected to an outlet, Ting analyzes 30 million measurements per second to detect tiny electrical anomalies and power-quality problems. On average, Ting detects and mitigates fire hazards in 1 out of every 60 homes it protects.

Whisker Labs works with a growing community of insurers who provide Ting to their customers for free.  More than one million Tings are deployed in the United States, and approximately 50,000 are installed each month. In his second appearance on Triple-I’s Executive Exchange video series in two years, Whisker Labs founder and CEO Bob Marshall reported to Triple-I CEO Sean Kevelighan on the product’s results to date.

“One of the cool things we’ve learned over the last couple of years is that insurers have found that Ting is like the gateway drug,” Marshall said. “I mean, if you actually get Ting into your customer’s home and we deliver a great experience to them, they’re much more willing to engage in water-loss prevention after that. So, it’s really critical that the homeowners engage.”

Ease of use has been critical to Ting’s success, Marshall said, pointing out that earlier attempts at similar products were “too complicated for the customer, too complicated for the carrier, and that’s why they didn’t work. With Ting, you just plug it in and it does its thing.”

Recent research demonstrated the efficacy and value provided by Ting. In partnership with Triple-I and Octagram Analytics, Whisker Labs found that Ting resulted in 0.39 fewer electrical fire claims per 1,000 home years of experience, translating to a fire claims reduction benefit of $81 per customer per year by the third year after installation. As Whisker Labs works with its growing community of insurers to extend Ting’s reach, Marshall believes these figures could improve even further.

“What we see in that study is that the claims frequency drops dramatically in the days, weeks, and months after you plug in Ting,” Marshall said, noting that the source for this finding “is not our data – it’s data from all the carriers that we work with.”

Kevelighan agreed that “from a carrier perspective, getting more of these into the community will make the community more resilient and more insurable,” particularly within dense neighborhoods and cities where fires can spread quickly. Such settings highlight the collective responsibility of risk mitigation on consumers as well as insurers, who play a key role in disseminating prevention solutions, Kevelighan stressed.

Though more public education surrounding IoT is needed, Marshall noted that homeowners familiar with Ting’s success are often receptive to additional IoT solutions for other risks, potentially sending ripple effects of risk mitigation throughout the industry. His firm and their research collaborators aim for similar versatility with the Ting study, whose methodology has broad applicability for many types of prevention solutions.

“‘Predict and prevent’ – that’s a vision that, I think, rings true for everybody,” Marshall concluded, because “the best claim is the one that never happens. We just want to be a key part of it and help drive it.”

Calls for Insurance-Price Legislation Would Hurt Policyholders, Not Help

Increased legislative involvement in regulating homeowners’ insurance pricing and rates – as recently called for by some officials in Illinois – would hurt insurance affordability in the state, rather than helping consumers as intended, Triple-I says in its latest Issues Brief.

Rising premiums are a national issue. They reflect a combination of costly climate-related weather events, demographic trends, and rising material and labor costs to repair and replace damaged or destroyed property. Average insured catastrophe losses have been increasing for decades, fueled in part by natural disasters and population shifts into high-risk areas. More recently, these and other losses to which the property/casualty insurance industry is vulnerable were exacerbated by inflation related to the pandemic and Russia’s invasion of Ukraine. Tariffs and changes in U.S. economic policies have since put even more upward pressure on costs.

These increasing costs – if not addressed – threaten to erode the policyholder surplus insurers are required to keep on hand to pay claims. If surplus falls below a certain level, insurers have no choice but to increase premium rates or adjust their willingness to assume risks in certain areas.

To avoid this, many insurers have filed with state regulators for rate increases – requests that often meet with resistance from consumer advocacy groups and legislators. Illinois would not be the first state to try to ease consumers’ pain by constraining insurers’ ability to accurately set coverage prices to reflect increasing levels of risk and costs.

Practicality, not politics

Such efforts, while perhaps politically popular, confuse one symptom (higher premiums) of a growing risk crisis with its underlying cause (increasing losses and rising costs). Using the blunt instrument of legislation to address the complexities and sensitivities of underwriting and pricing would tend to disrupt the market and further hurt insurance affordability – and, in some areas, availability.

Rather than target insurers with misguided legislation, the brief says, states would be wiser to work with the industry to improve their risk profiles by investing in mitigation and resilience. The brief describes the causes of higher premium rates nationally and in Illinois and how other states have successfully collaborated to address those causes and reduce upward pressure on – and eventually bring down –premium rates.

“Triple-I welcomes the opportunity to collaborate with state policymakers to develop constructive approaches to risk mitigation and resilience that will benefit communities and consumers,” the brief says.
