In 2025, U.S. insurers paid out $1.65 billion in lightning-related claims — a 59% year-over-year, according to a report by the Insurance Information Institute (III) and The Zebra published in June 2026. At the same time, the average cost per claim jumped 42.8%, now reaching more than $26,000 per claim.
These American figures reflect a global trend. Indeed, European and French statistics follow the same curve: damage caused by lightning increases every year, driven by the intensification of storm events linked to climate change. Yet, the vast majority of homeowners remain without lightning rods.
So, what insurers don't tell you — or not enough — is that appropriate lightning protection can significantly reduce your financial exposure.
Why do the ominous lightning strikes explode in 2025?
The answer is primarily climatic. According to Vaisala data, the frequency of severe thunderstorms increases in the Northern Hemisphere as surface temperatures rise. Consequently, more lightning strikes built structures, particularly in suburban and rural areas where homes are less protected.
Furthermore, the value of electronic equipment in homes has increased considerably over the last ten years. Thus, a single lightning strike can now simultaneously damage equipment worth easily between 10,000 and 30,000 euros: home automation equipment, electric charging stations, heat pumps, NAS servers, and video surveillance systems.
In addition, the number of claims has grown by 11.6% in 2025 — from 55,537 to 61,986 cases in the United States — which illustrates not only an increase in frequency, but also a better consideration of lightning risk by the insured themselves (III / The Zebra, 2026).
What exactly does a lightning strike cover?
Lightning damage is damage caused directly or indirectly by a lightning strike on a building or electrical installation. This can include structural damage (fire, partial roof destruction), electrical damage (fried appliances, destroyed electrical panel), or intangible damage (data loss, business interruption).
However, insurance coverage varies considerably depending on the chosen guarantees. While most comprehensive home insurance policies include basic lightning protection, deductibles can be high, and some sensitive equipment may only be partially covered—or not at all.
- Direct damages : fire started by lightning, structural collapse
- Indirect damage : power surge causing the destruction of electronic devices
- Not systematically covered : damage related to poorly protected cables, undeclared equipment, outdoor installations (pool pump, etc.)
Ultimately, even with good insurance coverage, lightning damage generates considerable delays, deductibles and administrative stress for the owners concerned.
Lightning protection: an investment, not an expense
An early streamer emission (ESE) lightning rod, conforming to standard NF C 17-102, offers active protection against direct lightning strikes. Contrary to popular belief, it does not "attract" lightning: it captures the upward leader to direct the strike towards a controlled down conductor, thus preventing the energy from passing through the structure.
Therefore, installing a certified ESE allows you to:
- Drastically reduce the risk of fire from direct impact
- Protect the structure and its occupants according to the protection levels defined by IEC 62305
- Increase the property's value and potentially reduce insurance premiums
- Documenting the installation's compliance for insurance purposes
In addition, an AtmoGuard surge protector associated with the system protects electronic equipment against induced surges — the most frequent damage and often the least well covered by insurance.
How to calculate the lightning risk to your property?
The international standard IEC 62305-2 defines the method for calculating lightning risk. This calculation takes into account several parameters, including:
- Ground lightning strike density (Ng) of the geographical area, expressed in impacts/km²/year
- The dimensions and location of the building
- The type of construction (materials, presence of protruding points)
- The use of the building and the value of the internal equipment
Therefore, a rigorous risk assessment determines whether active protection (ESE) is necessary, and what level of protection (NPT I to IV) should be implemented. This is precisely what LPS France certified installers perform before each solution deployment.
Furthermore, once installed, LPS Manager allows you to manage and schedule maintenance for the entire system—a key advantage for maintaining long-term compliance and facilitating insurance audits. Discover LPS Manager at lpsmanager.io.
What the 2025 figures reveal about your risk profile
The data from III for 2025 are particularly telling for owners without equipment:
- Average cost of a lightning strike: $26,622 (approximately €24,500) — an increase of 42.8% in one year (III, 2026)
- Cumulative probability of being struck by lightning over 30 years of ownership: significantly higher in areas with Ng ≥ 2 strikes/km²/year
- Average repair time after a roof fire caused by lightning: 3 to 6 months
However, the cost of installing a ESE in a detached house is generally between €1,500 and €4,000 (equipment + installation), depending on the building's characteristics. Therefore, the return on investment becomes clear when considering the risk over the property's lifespan.
However, the decision to invest in lightning protection should not be based solely on financial calculations. It also concerns the safety of the people living in the home—an aspect that insurance figures never fully reflect.
What concrete steps can you take to protect your home?
Here are the recommended steps for effective and compliant protection:
- Have a lightning risk assessment carried out : a certified professional evaluates the risk according to the IEC 62305-2 standard and determines the required level of protection.
- Choose a ESE certified to NF C 17-102 : the Paraton@ir and Ellips from LPS France are approved and offer protection radii adapted to all residential configurations.
- Install a certified surge protector : to protect electronic equipment against induced power surges
- Ensuring traceability of the installation : a documented installation simplifies procedures in the event of a claim and can favorably influence the terms of your insurance contract.
In conclusion, the projected 59% increase in lightning claims by 2025 is not a statistical anomaly; it confirms a structural trend linked to climate change and the proliferation of sensitive equipment in our homes. Therefore, investing in appropriate lightning protection—a certified surge protector and surge arrester—is one of the most rational decisions a homeowner can make today. Ultimately, prevention is better than cure.
