Homeowners insurance covers lightning-related damage, including fires, fallen trees, and the electrical surges behind most lightning claims. And those claims add up. U.S. insurers paid $1.65 billion in lightning-related homeowners claims in 2025, the highest total since 2020, according to the Insurance Information Institute (Triple-I). The average claim has grown sharply too, rising nearly 147% since 2017 as homes fill with more electronics and repair costs climb.

Some lightning damage is simply beyond your control, and that’s where your homeowners policy comes in, covering everything from structural damage to your belongings. But you can cut your risk before a storm ever hits. Install a whole-house surge protector to guard against the surges behind most claims, unplug valuable electronics when a storm is coming, and consider a full lightning protection system if you live somewhere strikes are common. A little prevention can save you a costly claim, and the deductible and rate increase that follow it.

How to protect your home and family from lightning

Lightning protection works best in layers, so combine a few of these rather than relying on any single one.

Guard your electronics

Add a whole-house surge protector at your electrical panel, around $200 to $300 installed, to blunt surges before they spread through your wiring.
Back it up with point-of-use surge strips rated for a high joule count (2,000+) on your most valuable devices, since a whole-house unit alone won’t stop everything.
Replace surge protectors every few years, as they degrade with each surge they absorb and stop working without any visible sign.
When a storm is in the forecast, unplug your most expensive electronics entirely. It’s the only guaranteed protection against a surge.

Protect the structure

If you live where strikes are common, a professionally installed lightning protection system gives a strike a safe path to the ground and is the strongest defense for the building itself.
Keep trees near your home trimmed, since a struck tree can fall or send current into your house.

Keep people safe

When thunder roars, go indoors, and stay off corded phones and away from plumbing and windows during the storm.
Wait 30 minutes after the last thunder before heading back outside.

Does homeowners insurance cover lightning damage?

Standard homeowners insurance covers lightning-related damage, subject to your deductible. Lightning can cause a wide range of losses, from house fires to fallen trees to power surges that fry expensive electronics, and most of these scenarios are covered under a typical policy.

After a lightning strike, you can file a claim with your insurer for the damage. You’ll need to pay your deductible before your insurance company covers the rest.

Coverage type	What it covers
Dwelling coverage	Damage to the structure of your home or attached structures, like a deck
Other structures coverage	Damage to structures not attached to your home, like a shed
Personal property coverage	Damage to your personal belongings
Additional living expenses coverage	Living costs if lightning damage forces you out of your home temporarily

How to guard against power surges

Installing a whole-house surge protector is one of the most cost-effective ways to guard against lightning damage. It’s far cheaper than a full lightning protection system and can prevent the electrical surges responsible for most lightning-related claims.

What lightning damage isn’t covered?

Even though lightning itself is a covered peril, a few related losses may fall outside a standard policy. Knowing the gaps ahead of time helps you avoid a surprise at claim time.

Power surges not caused by lightning. Many policies cover surges only when they’re the direct result of a lightning strike. A surge from a utility problem or faulty wiring may not qualify.
Older or high-value electronics at full value. Personal property is often paid out at actual cash value, meaning depreciation is subtracted. A ten-year-old TV won’t be reimbursed at what a new one costs unless you carry replacement cost coverage.
Damage beyond your coverage limits. High-value items like a home office full of equipment can exceed standard personal property caps. Scheduling those items or adding an endorsement closes the gap.
Flooding from a lightning-related storm. Wind and lightning are covered, but if the same storm causes flooding, that damage requires a separate flood policy through the National Flood Insurance Program or a private insurer.
Wear and tear or neglect. Damage an insurer traces to poor maintenance rather than the strike itself may be reduced or denied.

How do you file a homeowners insurance claim after a lightning strike?

Filing a claim after a lightning strike starts with documenting the damage and contacting your insurer as soon as possible. Here’s how to work through the process:

Ensure safety first. Before anything else, check for fire risk, exposed wiring, or other hazards, and evacuate if needed. Call 911 if there’s an active fire.
Document the damage. Take photos and videos of everything affected, from structural damage to fried electronics, before you move or repair anything.
Contact your insurer. Report the claim as soon as possible. Most insurers have a claims hotline or app you can use to start the process right away.
Save all receipts. Keep records of any temporary repairs, emergency supplies, or additional living expenses like a hotel stay, since these may be reimbursable.
Make a list of damaged items. For personal property claims, list out damaged belongings along with their approximate value and, if possible, proof of purchase.
Meet with the claims adjuster. Your insurer will send an adjuster to assess the damage. Walk them through everything and provide your documentation and receipts.
Review the settlement offer. Once the adjuster completes their assessment, your insurer will provide a settlement offer. Review it carefully, and ask questions if anything seems unclear or too low.

Will a lightning claim raise your insurance rate?

Filing a lightning claim can raise your premium, though weather-related claims like lightning tend to have a smaller impact than claims within your control, such as theft or liability. Because lightning is beyond your control, a single claim may not move your rate much, but a pattern of claims can.

Before you file, it’s worth weighing the repair cost against your deductible. If the damage is minor and close to what you’d pay out of pocket anyway, covering it yourself may cost less over time than a claim, especially if you’d lose a claims-free discount. For a major loss like a house fire or destroyed electronics, filing is almost always the right call, since that’s exactly what your coverage is for.

Do the math before you file

Compare the repair cost to your deductible first. Small claims can cost you more in higher premiums and a lost claims-free discount than you’d get back, so save your coverage for the losses big enough to make a claim worth it.

How can you protect your home from lightning damage?

The most effective way to protect your home from lightning is installing a lightning protection system, though there are also budget-friendly options that can meaningfully reduce your risk.

A lightning protection system gives lightning current a designated path to the ground. It doesn’t attract or repel a strike, it simply intercepts it and safely redirects it away from your home. These systems typically cost $2,000 to $4,500 to install on a private home, and up to $70,000 for a high-rise building, and need to be installed by specially trained professionals.

If a full system isn’t in your budget, there are still several steps that can lower your risk:

Install surge protectors, either whole-house or at the point of use, to guard against damage from power surges during a strike
Unplug electronics before a storm hits or if you’ll be away during storm season, since unplugged devices can’t be damaged by a surge
Add a grounding system outside your home to help direct any electrical charge safely into the ground

Combining a few of these lower-cost measures with basic storm preparedness can go a long way in reducing your risk, even without a full lightning protection system in place.

Frequently asked questions

Does home insurance cover lightning damage to electronics?

Damage to electronics from a lightning strike is generally covered under your personal property coverage. Keep in mind that many policies pay out at actual cash value, so older devices may be reimbursed for less than the cost of replacing them, unless you carry replacement cost coverage.

Does insurance cover a power surge from lightning?

Many homeowners policies cover power surges when they’re the direct result of a lightning strike. Surges from other causes, like a utility issue, may not be covered, so it’s worth checking your policy for the specifics.

How much does lightning damage cost to repair?

It varies widely depending on what’s affected, from a few hundred dollars for a fried appliance to tens of thousands for a fire. The national average lightning claim has climbed in recent years, reaching $26,616 in 2025, driven by rising repair costs and the growing value of electronics inside homes.

Is lightning damage common where I live?

Lightning claims cluster in a handful of states. In 2025, Florida led the nation in the number of lightning claims, while Texas saw the highest average cost per claim. Even so, no home is immune, and standard coverage applies wherever you live.
