Climate Nonprofits Take Responsibility for Terminated U.S. Databases

Leave a comment

By Lewis Nibbelin, Research Writer, Triple-I 

Amid federal funding and staffing cuts to major science agencies last year, various nonprofit organizations stepped up to maintain their essential climate and weather research. Such risks may become increasingly difficult to predict and prevent, however, as key agencies, such as the National Center for Atmospheric Research (NCAR), remain targets for disinvestment or termination.

Private sector takes charge

In the spring of 2025, the federal administration attempted to rescind tens of billions of dollars in research and hazard mitigation grants, leaving many programs – like FEMA’s Building Resilient Infrastructure and Communities (BRIC) program – in legal limbo as legislators continue to debate their futures. Alongside funding delays and cancellations, mass firings led to the shuttering of several climate and weather information resources – until private associations and researchers mobilized to revive them.

Former NOAA staffers, for instance, regrouped to rescue the organization’s climate.gov website, which attracted nearly one million visitors per month – including teachers, policymakers, and media outlets – before being dismantled last June. Under a new domain, the site will both restore deleted information and resume tracking and explaining the effects of climate risk to public audiences, relying exclusively on nonprofit funding, according to project director Rebecca Lindsey in an interview with NPR.

Similarly, nonprofit Climate Central recently released its first billion-dollar weather and climate disaster report since assuming responsibility for that dataset, which former NOAA climatologist Adam Smith continues to oversee. Beyond rebuilding NOAA’s database, the organization aims to expand upon it in the coming years to track smaller catastrophes, providing insurers and other stakeholders more reliable information to understand individual disasters.

An initiative spearheaded by the American Geophysical Union (AGU) and the American Meteorological Society (AMS) is now aiming to help fill research gaps left by the elimination of the National Climate Assessment (NCA), a series of congressionally mandated reports published since 2000 to inform climate risk mitigation strategies for municipalities and businesses. Though not intended to replace NCA, the new data collection “provides a critical pathway for a wide range of researchers to come together and provide the science needed” to “ensure our communities, our neighbors, our children are all protected and prepared,” said AGU president Brandon Jones.

Grassroots efforts to archive federal climate databases and tools before they disappear have also gained traction around the globe to ensure these resources remain publicly available. The nonprofit Open Environmental Data Project, for example, saved a now-deleted tool to identify communities disproportionately impacted by climate and weather risks through its Public Environmental Data Project.

Crucial agencies under scrutiny

While the latest government spending package has largely spared science funding from further reductions, the Trump administration had proposed cuts amounting to a 21 percent drop from fiscal 2025 levels. Other agencies face potential dissolution, particularly NCAR – widely considered the largest federal climate research program in the U.S.

Managed by the University Corporation for Atmospheric Research (UCAR) in collaboration with the National Science Foundation (NSF), NCAR houses advanced computing and modeling systems to support weather forecasts, mitigation planning, flood mapping, and other datasets needed across the transportation, engineering, utility, and risk and insurance industries.

Describing NCAR’s research as critical to “protecting lives and property, supporting the economy, and strengthening national security,” UCAR president Antonio Busalacchi said in a statement that “any plans to dismantle NSF NCAR would set back our nation’s ability to predict, prepare for, and respond to severe weather and other natural disasters.”

“NCAR datasets have been vital in improving our understanding of the atmosphere and ocean,” said Phil Klotzbach, lead author of Colorado State University’s seasonal hurricane forecasts and Triple-I Non-Resident Scholar. “These tools have been critical input to CSU’s seasonal hurricane forecasts for over 25 years.”

NCAR’s pending fate coincides with a recent study from the University of Florida that suggests the budget cuts in part reflect pervasive distrust in scientific institutions, necessitating stronger efforts to communicate the value of scientific work to the public. But as more independent groups take on the responsibilities once affiliated with federal organizations, building public relationships may prove even more challenging, posing uncertain implications for the future of climate and weather data as a whole.

Resilient U.S. P/C Market Performance Sets Stage for a Complex 2026

Leave a comment

By William Nibbelin, Senior Research Actuary, Triple-I 

The U.S. property/casualty insurance industry demonstrated notable resilience throughout 2025, navigating a landscape marked by significant regional catastrophes and shifting economic pressures, according to the latest Insurance Economics and Underwriting Projections: A Forward View report from Triple-I and Milliman.

As the industry moves into 2026, the report notes, it does so from a position of historical strength yet faces an increasingly nuanced outlook shaped by market softening and lingering macroeconomic uncertainties.

The Triple-I/Milliman report is based on data through the third quarter of 2025,

Industry-Wide Performance and Profitability

The P/C insurance industry is forecast to achieve its lowest net combined ratio (NCR) in over a decade for the full year 2025. This achievement is particularly significant, given the challenges faced early in the year, including the devastating Los Angeles wildfires in January 2025.

A key driver of this success was the first Atlantic hurricane season with no U.S. landfall in 10 years. However, while profitability reached peak levels, top-line growth began to moderate. Aggregate net premium growth across all lines for 2025 is expected to be 5.9 percent, reflecting a continued slowing of the growth rate compared to 2024.

“We’re on track to achieve the lowest net combined ratio in over a decade, thanks in part to a hurricane season that spared the U.S. and strong homeowners performance, even after the Los Angeles fires in Q1 2025,” said Patrick Schmid, Ph.D., chief insurance officer at Triple-I. “Growth in personal lines premiums remains solid, and the narrowing gap between personal and commercial lines performance points to a cautiously optimistic outlook for the industry.”

Economic Outlook: Stability Meets Vulnerability

While the broader U.S. economy and the P/C sector remain stable, economists are keeping a close watch on emerging risks. The industry’s ability to maintain its momentum in 2026 may be tested by rising political and geopolitical tensions, as well as potential shifts in the labor market.

“Overall, the P/C insurance industry and the broader U.S. economy remain stable,” said Michel Léonard, Ph.D., CBE, chief economist and data scientist at Triple-I. “However, despite stronger-than-expected GDP growth in the third quarter, a closer look at the data suggests the U.S. economy may be increasingly vulnerable to rising economic, political, and geopolitical uncertainty. In particular, P/C replacement costs could still see significant increases in 2026, weighing on overall P/C performance.”

Léonard further highlighted that the labor market serves as a critical indicator, noting that a rise in the unemployment rate toward 5.0% over the next six months could potentially trigger an economic contraction.

Underwriting Results by Line of Business

Personal lines continue to anchor the industry’s profitability. Personal auto remains a standout performer with a forecast 2025 NCR of 94.4, an improvement over 2024 results. However, premium growth in this sector has slowed significantly, with net written premium growth expected to land at 3.6 percent — its lowest level since 2020. Homeowners’ insurance also showed remarkable recovery. Despite the heavy losses from the Los Angeles fires in the first quarter, the line’s 2025 NCR is forecast at 99.6, placing it on par with 2024 performance.

Commercial lines continue to face ongoing challenges in liability. While most of the industry enjoys profitability, general liability and commercial auto remain the only major lines forecast to stay above a 100 NCR for 2025. General liability continues to struggle with the highest Q3 direct incurred loss ratio reported in over 15 years.

Jason B. Kurtz, FCAS, MAAA, principal and consulting actuary at Milliman, detailed these persistent hurdles.

“General liability faces continued challenges,” Kurtz said. “Our 2025 net combined ratio is forecast to be similar to 2024, among the worst in over a decade. Losses are high, with Q3 direct incurred loss ratios being the highest in at least 25 years.”

He added, “While conditions may improve in 2026-2027, profitability remains a hurdle. Our general liability’s NCR expectations have risen following a challenging Q3, reflecting ongoing pressure in the segment. While some coverages are experiencing soft market conditions, aggregate premiums have been growing, but not enough to keep pace with loss trends.  We anticipate additional premium growth will be needed to improve general liability profitability.”

Workers’ compensation remains the strongest performing major line, with NCRs forecast to stay in the high 80s to low 90s through 2027. This sustained success is attributed to disciplined risk management and favorable prior accident year development.

“NCCI’s latest loss ratio trends continue to show declines,” said Donna Glenn, NCCI chief actuary. “In the current environment, modest year-to-year decreases are still expected.” Glenn noted that “while there have been a few rate increases filed in NCCI states, every state has its own story, and based on the latest data, NCCI does not anticipate any imminent reversal of current trends.”

La. Auto Insurance Rates Benefit From Declines
in Frequency, Severity

Leave a comment

By Lewis Nibbelin, Research Writer, Triple-I

More than 20 requests for auto insurance rate decreases have been filed with Louisana’s Department of Insurance by insurers since mid-2025. According to the department, the decreases were driven by reductions in accident frequency and severity.

“I’m glad to see positive movement on auto rates in Louisiana for the first time in years,” said Louisiana Insurance Commissioner Tim Temple. “Because fewer accidents are contributing to these lower losses for insurers, we should not necessarily expect to see this level of decrease in future years unless we continue to pursue legal reform that addresses the foundational reasons our rates are the highest in the country.”

Temple said he hopes for further rate changes as the market continues to stabilize, citing Florida’s recent premium reductions after sweeping tort reform legislation in 2022 and 2023.

Longstanding affordability challenges

Among those who filed for rate decreases include Louisiana’s largest auto insurers, with the latest reductions impacting nearly 470,000 Progressive policyholders, or roughly 23.5 percent of the state’s auto market. More than one million State Farm policies also achieved lower average rates implemented this month.

While the statewide decreases can offer relief for drivers in one of the least affordable states for auto insurance, Temple cautioned that rates for individual policyholders will differ based on personal risk factors, urging consumers to shop among the “30 companies that have taken a rate decrease.”

The announcement arrives less than a year after Louisiana lawmakers passed a 2025 tort reform package to curb excessive lawsuits and a rate of bodily injury claims more than twice the national average. Beyond fueling higher insurance premiums in the state, such practices generate an annual $965 “tort tax” on every Louisianan and cost over 40,562 jobs per year, as highlighted by Triple-I’s consumer awareness campaign to build support for the reforms.

Other 2025 legislative measures, however, stipulate increased regulatory intervention in rate-setting, which can create further strain on an insurance market just beginning to recover. Another bill targeting nuclear verdicts (awards of $10 million or more) also failed to pass, playing a role in the state’s recurring spot on the American Tort Reform Foundation’s annual list of “judicial hellholes.”

Noting that reduced accident frequency contributed to the rate changes, Temple said in a statement that “we should not necessarily expect to see this level of decrease in future years unless we continue to pursue legal reform that addresses the foundational reasons our rates are the highest in the country.”

Lessons from Florida

Measurable benefits from Louisiana’s existing reforms may require a few more years to unfold, Temple added, based on the trajectory of similar legislation in Florida. In 2022, Florida accounted for over 70 percent of the nation’s homeowners claim-related litigation, despite representing only 15 percent of homeowners’ insurance claims, according to the state’s Office of Insurance Regulation (OIR). State legislators responded to the crisis with several tort laws that, among other things, eliminated one-way attorney fees and assignment of benefits (AOB) for property insurance claims.

Under the reforms, 17 new insurance companies have entered the Sunshine State and dozens of homeowners’ and auto insurers have filed for rate decreases, with Citizens Property Insurance – the state’s insurer of last resort – approved for major average rate cuts this spring, according to a recent announcement from Florida Gov. Ron DeSantis.

A 50 percent drop in Citizens policies in 2025 helped facilitate the cuts, reflecting the largest transition of policies back to the private market in a decade. Later that year, additional cost-savings achieved through the reforms helped state regulators secure nearly $1 billion in premium refunds for Progressive auto insurance policyholders in the state.

Though the specific policy levers may differ, Florida’s reforms continue to model the kinds of market improvements that states like Louisiana and Georgia can expect after successfully passing their own tort legislation. State government moves like these are essential to eradicating legal system abuse and keeping insurance affordable and available, especially as legislative challenges to legal reform persist.

“Premiums are lowering because we’ve enacted real reforms and withstood the pressure to reverse course,” DeSantis said. “We will hold firm in our commitment not to go back to the broken insurance market of the past.”

Few, High-Powered Storms Defined 2025 Hurricane Season

Leave a comment

By Lewis Nibbelin, Research Writer, Triple-I

Though producing no U.S. landfalls for the first time in a decade, the 2025 Atlantic hurricane season generated deadly tropical storms, above-average days of major hurricane activity, and millions in economic losses, underscoring the enduring community preparedness required against this evolving peril.

Among the five hurricanes that did form, four reached Category 3 strength or higher, including three Category 5 storms – marking only the second year on record that more than two such storms occurred in the Atlantic. A new Triple-I Issues Brief examines their impacts and how they align with emerging climate and weather trends, particularly within inland areas hit by flooding from remnants of the storms.

Flood exposure spreads inland

While not to the scale of U.S. hurricanes in 2024, the year’s tropical storms were similarly destructive, with remnant moisture from Tropical Storm Chantal contributing to $500 million in damage, Gallagher Re estimates. In many affected North Carolina counties, less than 1 percent of households were covered by the National Flood Insurance Program (NFIP), highlighting a growing flood protection gap in areas once considered low-risk.

Demographic shifts also play a crucial role in the devastation as more people move into harm’s way and build their homes bigger and more expensive than before. While various flood-prone areas along the coasts lost more residents than they gained in 2024 – for the first time since 2019 – it is critical to remind home and business owners about rising flood risks throughout the country and the importance of staying protected.

Stronger, wetter weather

Warming oceans also fuel “rapid intensification,” or an increase in maximum sustained winds by at least 35 mph in a 24-hour period. Since 1980, over 80 percent of landfalling U.S. hurricanes – altogether costing at least $5 billion in damages – underwent rapid intensification at some point during their lifecycle, according to a 2025 American Geophysical Union (AGU) study.

Describing rapid intensification events as “a pronounced increasing trend,” AGU study coauthor Dr. Phil Klotzbach – a senior research scientist in the Department of Atmospheric Science at Colorado State University and Triple-I non-resident scholar – said such storms “tend to weaken at a slower rate as they move inland,” compounding challenges for residents who “aren’t necessarily as prepared as they should be.”

Hurricane Melissa – 2025’s strongest and deadliest storm – showcased the toll from this mounting intensity. Claiming more than 100 lives across the Caribbean, Melissa rapidly intensified before hitting Jamaica as a Category 5 hurricane, becoming one of the fastest-intensifying Atlantic storms ever recorded and the most powerful hurricane to make landfall in the country’s history.

Cutting-edge analytics

As advances in computing power and data collection have improved traditional tools in recent years, forecasters and insurers have built up their arsenal to combat the unpredictability of climate and weather risks. For instance, barometric pressure – found both more accurate and easier to gauge than the wind speeds traditionally used to predict storm damage – served as the primary trigger for a  $150 million parametric policy for Jamaica which paid out in full after Hurricane Melissa.

“Displaying the kind of predictive power that can help insurers price risk and mitigate costly claims, these technologies can inform conversations at all levels to encourage investment in resilience,” the brief states.

Insurer-Backed Tech Leads Effort to Address Deferred Maintenance

Leave a comment

By Lewis Nibbelin, Research Writer, Triple-I

As property owners grapple with mounting repair and replacement costs, a backlog of needed upkeep continues to grow, with public buildings alone facing a deferred maintenance cost of nearly $100 billion across states, according to recent Pew estimates. Left unaddressed, these maintenance gaps can escalate into greater damages and more expensive repairs when catastrophes happen, leading to costlier claims.

Digital platform HelixIntel aims to bridge the gap by helping businesses and organizations create maintenance strategies in partnership with the insurers who protect them. Offering a “one-stop” approach to maintenance management, the platform can capture real-time risk data while streamlining maintenance organization and productivity, driving safer behaviors and preventative practices before facilities or equipment break down.

“What we’ve seen is that everyone wants to be involved and know what they can do to help,” said CEO and co-founder Jon DeWald, in an Executive Exchange interview with Triple-I CEO Sean Kevelighan. “What we’re working on is really showing that there’s two teams – both properties and insurers, who have the same mission in mind – and being able to provide tools that allow them to collaborate.”

Noting the unique maintenance required across various industries – from “large school districts with facility directors” to small businesses “where one person takes care of everything” – DeWald discussed how HelixIntel maximizes its impact by working directly with insurers, who then distribute the platform to their customers. The platform teamed up with Hartford Steam Boiler (HSB), for instance, to support policyholders with equipment breakdown coverage.

Beyond helping lower the cost of entry to new tech for consumers, such partnerships allow the platform to leverage the comprehensive data that insurance carriers have access to, facilitating predictive recommendations rather than purely reactive maintenance, DeWald explained.

“We’ve been saying for some time at Triple-I that the insurance industry is shifting from just detecting and repairing after a catastrophe to now predicting and preventing,” said Kevelighan, adding that, by quantifying maintenance, innovators like HelixIntel enable insurers and consumers to “really understand the return on their own investment.”

Quantifying the benefits of maintenance investments is also essential to inform effective risk mitigation and resource allocation for policymakers, who often lack insight into the impacts of deferred maintenance due to insufficient data collection and reporting. Tracking asset health, maintenance tasks, and other property-specific data through a centralized management system can help state facilities identify overdue repairs and develop long-term maintenance planning, fostering more resilient communities.

Though once regarded as a “cost center,” maintenance and other risk management initiatives are “moving more and more into the actual business strategy, so that businesses and the insurance companies that are focused on those businesses are able to prevent those losses and keep businesses open,” Kevelighan concluded.

Severe Winter Weather Ravages U.S. Communities

Leave a comment

By Lewis Nibbelin, Research Writer, Triple-I

Millions of Americans remain on alert for a severe weather outbreak across the country after devastating atmospheric rivers, tornadoes, and winter storms raged at the close of 2025, causing multiple deaths and significant property damage from coast to coast.

Southern California saw its wettest Christmas Eve and Day ever recorded, with more than 17 inches of rainfall in one area of Ventura County and 10 inches in parts of the San Gabriel Mountains in Los Angeles County. Downing trees and power lines, the heavy rains triggered flash flooding and mudflows that hit hundreds of homes, prompting road closures and power outages throughout the state.

Another unusual weather system spawned 13 tornadoes across the Great Lakes in late December, with six in Central Illinois alone, damaging numerous homes. Prior to last year, only five December tornadoes had been recorded in that forecast area, the last of which occurred in 2021. Frigid cold conditions followed the storm as a bomb cyclone – part of the same system that drenched California – swept from the Midwest to the East Coast.

Defined as a rapidly intensifying non-tropical storm in which pressure drops by at least 24 millibars over a 24-hour period, the bomb cyclone generated blizzard conditions resulting in power outages for more than 300,000 customers and a massive Interstate pile-up involving over 50 cars and multiple semi-trucks in Detroit, Mich. Several feet of snow buried Upstate New York, with the hardest-hit areas in the Lake Ontario snowbelt.

As conditions begin tapering off on the West Coast, the first cross-country storm of 2026 is expected to bring torrential rain and snow in the South and much of the Midwest later this week. Threats of flash flooding as well as hail, tornadoes, and damaging winds loom across both regions, with heavy rains possible in the Northeast.

As always, Triple-I urges residents to stay informed, be prepared, and follow the instructions of local authorities. Checking insurance coverage is critical to such preparation, especially as atmospheric rivers, severe convective storms, and inland flooding become increasingly common. Many noncoastal communities impacted by recent flood events lack sufficient flood protection, and Californians grappling with claims from the storms may also be unaware they need separate flood policies for flooding and mudflow.

PWC: A.I. Megadeals Spur Insurance M&A Growth

Leave a comment

By Lewis Nibbelin, Research Writer, Triple-I

Deals exceeding $1 billion drove insurance industry mergers and acquisitions (M&A) in 2025, aligning with a surge of artificial intelligence-based megadeals in the broader M&A market, according to PwC’s U.S. Deals 2026 Outlook. While total M&A deal value rose to $1.6 trillion through November 30 – the second-highest value ever recorded – the insurance sector remained consistent, though ongoing economic uncertainty could challenge this stability.

Upward trends emerge

Owing 93 percent of its value to megadeals, the insurance industry’s deal volume totaled $31.8 billion during the second half of 2025, compared to $30 billion during the previous six months. Heading into 2026, PwC projects that both improved loss ratios and rising pressure on property and casualty rates will facilitate further deals, as the industry’s performance can attract investors while also leading carriers to seek growth through more acquisitions.

“In coming months, expect interest rate developments and an industry-wide search for growth to strongly influence insurance deals activity,” said Mark Friedman, PwC U.S. insurance deals leader.

Conversely, total M&A market value increased by 45 percent from 2024, with more than 20 percent of its 74 deals valued at $5 billion or more relating to A.I. Such market activity suggests “A.I. is significantly accelerating software and consumer goods development” by boosting portfolio strategies, operational efficiencies, and other gains across various industries, the report notes.

Ramzi Ramsey, a senior managing director at Blackstone Growth, emphasized the increasing role of A.I. as a core driver of M&A growth, arguing that “companies who are viewed to benefit from AI tailwinds are seeing outsized multiples and deal activities,” whereas “companies where AI is viewed to be a detractor, or if the AI impact is cloudy, may have no bid.”

Middle-market lags

Though still the third-largest in the past decade, overall M&A market volume rose by only 2 percent from 2024, with middle-market deals between $100 million to $1 billion slumping to their lowest volume since at least 2013. Tariff policy shifts largely fueled these figures, reflecting greater caution among dealmakers – particularly smaller businesses – as supply-chain risks became more unpredictable.

While sudden policy changes and recent trade disputes could persist into the new year, PwC’s report found that “interest rate cuts this year have already helped mid-tier corporates, and further Federal Reserve Board action in 2026 could go a long way in relieving pressure on them,” especially as current tariff policies continue to stabilize.

In combination with declining interest rates, “products that can withstand declining consumer performance and confidence” should help the insurance sector remain active in 2026, the report adds, pointing to A.I. investments as essential to maintaining “solid ground” in the M&A market.

In a year marked by severe convective storm-induced damage across the United States, timely and accurate data is more essential than ever to understand, predict, and prevent these evolving weather perils. Though federal cuts to weather monitoring and modeling have raised concerns about the industry’s capacity for risk mitigation, a new research center backed by insurers and the U.S. National Science Foundation (NSF) aims to help bridge the gap.

Directed by Dr. Victor Gensini, a professor at Northern Illinois University and a Triple-I non-resident scholar, the Center for Interdisciplinary Research on Convective Storms (CIRCS) will leverage the expertise of nearly two dozen scientists to develop research focused on advancing resilience against severe convective storms, which range from thunderstorms with lightning to tornadoes, straight-line winds, and hail.

Northern Illinois University and the University of Wisconsin-Madison launched CIRCS with $1.5 million in funding from NSF, as part of a joint initiative with the National Oceanic and Atmospheric Administration (NOAA) to create an Industry-University Cooperative Research Center (IUCRC) that can support the insurance sector.

Beyond funds under the IUCRC model, CIRCS also receives “funding for research, students, and lab equipment” from private industry members, most of whom are “insurance and reinsurance companies interested in research on convective storms,” said Gensini, who teaches in NIU’s Department of Earth, Atmosphere, and Environment. He added that CIRCS includes actuarial scientists within its panel of experts to “approach this specific peril from multiple directions.”

Rising in both frequency and severity, convective storms accounted for $42 billion in global insured losses during the first half of 2024 alone, driven by 12 U.S. storms with $1 billion or more in losses each, according to a Swiss Re report. Later Gallagher Re data supports the trend, with large U.S. thunderstorms contributing to $46 billion in insured losses through the third quarter of 2025, the fourth-costliest year on record.

Paradigm-setting research

In addition to the center’s launch, Gensini recently celebrated a major data haul gathered during the largest hail study ever conducted, known as ICECHIP – short for In-situ Collaborative Experiment for Collection of Hail in the Plains. Funded with an $11 million grant from NSF, the field study sent Gensini and more than 100 other scientists and students across the Great Plains to chase and analyze hailstorms, which facilitate as much as 80 percent of severe convective storm claims in any one year.

Collecting more than 10,000 stones for study, the researchers hope to reduce hail risk through improved forecasting, enabling residents to better protect themselves and their belongings before a hailstorm hits. As the first field campaign dedicated to studying hail since the 1970s, ICECHIP’s participants expect their data to inform research analysis for years to come, NIU reported.

“We recovered tennis-ball-sized hail or greater in about half of our instrument deployments,” Gensini said. “You hope and dream for these kinds of observations in order to push forward hail science.”

By partnering academia with industry and government agencies, CIRCS and ICECHIP showcase the kinds of collaborative, data-driven solutions needed to address climate risks in ways that respect the unique needs of all affected groups, fostering risk management strategies that can build resilience at a community level.

Storm-Resistant Roof Efforts Gain Ground

Leave a comment

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.”

Commercial Lightning Losses: You Can’t Manage What You Don’t Measure

Lightning strikes costs homeowners more than $1 billion a year – but it’s unclear how much businesses lose through lightning-related damage. This is because many fires at commercial properties are recorded simply as “general fire damage”, making it hard to quantify lightning-specific losses or understand true commercial exposure.

In some jurisdictions, fire inspection forms lack a designated field for lightning. Further, inspectors may not be trained nor instructed to identify lightning as a cause. As a result, lightning-related fires often go unrecognized.

Insurers can help address these gaps by collaborating with fire service professionals.

Properly designed and installed lightning protection systems (LPS) significantly reduce risk and mitigate losses. To support accurate risk assessment, encourage mitigation, and appropriately value these systems, lightning must be identified as a distinct cause of loss in claims data.

Lightning damage also extends well beyond fire. Electrical surges can destroy wiring, controls, and electronic infrastructure, resulting in expensive business interruption. Illustrative cases reveal the scale of potential loss:

• A furniture manufacturer on the East Coast incurred over $1 million in insured damages from a single strike, including structural harm, inventory losses, production downtime, and lost revenue.
• A Midwestern apartment complex experienced over $50 million in claims for structural and electrical damage, as well as the displacement of residents.

These incidents demonstrate the high stakes of lightning events and the importance of mitigation. However, because consistent data across commercial properties is scarce, insurers, risk managers, and building owners lack a full picture of exposure, highlighting the need for better claims tracking to inform risk assessment and mitigation strategies.

A lightning protection system is far more than a single rod and cable. It is a coordinated network designed to intercept and safely redirect lightning energy away from structures and equipment. A compliant LPS includes five essential components:

  • Strike termination devices (air terminals/”rods”): metal rods that intercept a lightning strike.
  • Conductors: heavy braided cables that carry current toward the ground.
  • Grounding (earth termination): electrodes/loops that disperse energy into the earth.
  • Bonding / potential equalization: connecting metal and internal systems (ie. water, fire, security) so they rise/fall in voltage together, preventing side-flash.
  • Surge protective devices (SPDs): protect power/data/controls from transient over voltages.

Systems missing any of these elements, or not installed to national standards, are insufficient. Compliance with NFPA 780, UL 96A, andLPI 175 ensures thorough protection.

Proper installation, inspection, and maintenance are critical. Systems should be installed by certified lightning protection contractors and inspected/certified through independent third-party inspection programs. Ongoing maintenance and re-inspection, particularly after roof or structural changes or severe storms, helps ensure that the system continues to operate as intended.

Lightning protection systems, installed according to the standards, defend against both direct and indirect strikes. Direct strikes occur when a lightning bolt hits a building, potentially causing fire, structural damage, or electrical failure. Air terminals intercept the strike, and conductors safely route energy to the ground. Indirect strikes happen when nearby lightning induces surges through utility lines, piping, or the ground. SPDs, bonding, and grounding systems manage these surges, helping to protect life-safety systems, critical operations, and business continuity.

By addressing both direct and indirect risks, lightning protection systems protect property, minimize downtime, and reduce potential claims/costs.

Effective loss control begins with risk assessment. NFPA 780 provides a straightforward methodology that considers local lightning frequency, building height and footprint, occupancy, and operational continuity needs. Facilities where downtime carries high costs — or where electrical or operational systems are vital to the community — should be prioritized. When risk assessment is paired with certified installation, third-party inspection, and routine maintenance, the result is fewer and less severe claims, along with more resilient operations.

Lightning damage is preventable, but tracking is not as consistent as it is for other hazards, such as flooding. Standards-compliant lightning protection systems mitigate risks and improve resilience.

Insurers can reduce claims severity and gain better insights into lightning losses by tracking incidents, incentivizing mitigation and supporting standards-based protection. In addition, there is an opportunity to collaborate with fire service professionals to address gaps in fire inspection reporting and ensure lightning-related fires are accurately identified.
