If your house gets struck by lightning, the bolt can start fires inside your walls, destroy your electrical system, damage gas lines, and crack masonry, and your standard homeowners policy will generally pay to repair it. The urgent part is the next hour: get everyone to safety, call the fire department even if you see no flames, and stay away from plumbing and anything plugged into an outlet until the house has been checked.
The First Hour: Safety Steps
If anyone has been struck or injured, call 911. Cell phones are safe to use during and after a storm.1Centers for Disease Control and Prevention. Safety Guidelines: Lightning If you smell smoke or see fire, evacuate and call the fire department from a safe distance outside.
Call the fire department even if everything looks fine. Lightning routinely starts fires inside wall cavities, attic insulation, and other concealed spaces that smolder for hours before breaking through. Firefighters use thermal imaging to detect heat behind drywall, and that scan is the only reliable way to rule out a hidden fire.
While you wait, stay away from water and anything plugged in. Lightning travels through plumbing and electrical wiring, so do not shower, wash dishes, or touch appliances, even after the storm appears to have passed.1Centers for Disease Control and Prevention. Safety Guidelines: Lightning Corded phones are also unsafe. Cordless and cell phones are fine. If your main breaker is easy to reach, shutting it off helps stop further surge damage traveling through compromised wiring.
The Damage You Can See and the Damage You Can’t
Fire and Structural Damage
A direct strike produces enough heat to ignite combustibles anywhere the bolt’s energy travels, and the resulting fires often start in attic insulation, wall cavities, or along wiring runs where you can’t see them. The superheated air around the bolt also expands fast enough to create a shockwave. That shockwave can crack masonry, shatter windows, and blow shingles or siding off the exterior. Brick chimneys and concrete foundations are particularly vulnerable.
Electrical System Damage
Lightning sends a massive surge through the copper wiring and plumbing in your home. It destroys sensitive electronics, fries circuit boards in HVAC units and appliances, and can melt or fuse wiring together. Even without a fire, you may be looking at a complete rewiring job. Hardwired systems like water heaters, security alarms, and garage door openers are often damaged along with everything plugged into an outlet.
Gas Line Hazards
Homes with corrugated stainless steel tubing, the flexible yellow gas piping common in newer construction, face an extra risk. A nearby strike can energize improperly bonded CSST and burn a hole through the thin tubing, causing a leak or fire. The National Fuel Gas Code requires CSST to be bonded to the home’s electrical grounding system.2Lightning Protection Institute. NFPA 54 To Include Bonding Requirements If you have CSST and have not confirmed proper bonding, make a post-strike gas inspection part of your checklist.
What Homeowners Insurance Pays For
The standard HO-3 policy, which most U.S. homeowners carry, covers lightning damage to both the structure of your home and your personal belongings.3Insurance Information Institute. Homeowners 3 – Special Form Repairs to the dwelling itself, including wiring, roofing, and masonry, are paid at replacement cost, meaning the insurer covers what it takes to rebuild with similar materials without deducting for age or wear.
Personal property is treated differently. By default, items like televisions, appliances, and computers are paid at actual cash value, which subtracts depreciation. A five-year-old television that cost $1,200 new might only pay out $400. Many insurers sell a replacement cost endorsement for contents at an added premium. Check your declarations page to see which method applies before you need it.
If You Can’t Live in the House
If the damage makes your home uninhabitable, Coverage D (loss of use) pays the extra costs of living elsewhere during repairs. That usually includes hotel stays, restaurant meals above your normal grocery spending, pet boarding, additional commuting costs, and temporary storage. Coverage D typically equals 10 to 20 percent of your dwelling coverage, so a home insured for $300,000 might have $30,000 to $60,000 available. It lasts until the house is repaired or the limit is exhausted.
Your Deductible
Before the insurer pays anything, you pay the deductible you agreed to when you bought the policy. If repairs come to $15,000 and your deductible is $1,000, the insurer pays $14,000. If the damage is less than your deductible, filing may not be worth it. Look at your declarations page for the exact number.
Filing the Claim
Document Everything
Strong documentation is what makes a claim move. Photograph and video every affected area: the strike point on the roof, charred wiring, cracked masonry, damaged electronics, scorch marks on walls and ceilings. For personal property, make a detailed inventory with each item’s approximate age, original cost, and replacement value. Receipts, credit card statements, or bank records help establish value for the expensive items.
Professional reports carry weight. An electrician can produce an origin-and-cause report tying the electrical damage specifically to the lightning event, which heads off denials based on wear or pre-existing conditions. For cracks in a chimney or foundation, a structural engineer’s inspection, typically $100 to $1,000 depending on scope, documents the damage with professional authority.
Notify Your Insurer
Contact your insurance company as soon as you can. Most insurers take claims by phone, online portal, or mobile app. Reporting the claim triggers assignment of a field adjuster, who will schedule a physical inspection.
Walk the adjuster through every affected area during the visit and hand over copies of your photos, inventory, and professional reports. The insurer may also ask for a Proof of Loss form, a sworn, notarized document that states your total financial demand and summarizes your evidence.4Federal Emergency Management Agency. Proof of Loss Form Submit it by the deadline in your policy; missing that deadline can be grounds for denial. Keep copies of everything you send.
If You Have a Mortgage
Insurance checks for home damage are typically made out to both you and your mortgage lender. The lender has a financial interest in the repairs and must endorse the check before you can use the money. In many cases the lender holds the funds in escrow and releases them in installments as work progresses, sometimes with a final inspection before the last payment. Call your lender early so you aren’t surprised when the check arrives.
If You Disagree With the Insurer
Reservation of Rights Letters
During the investigation, you may receive a reservation of rights letter. It is a formal notice that the company is still investigating and has not decided whether the policy covers your loss. It is not a denial. It means the insurer has flagged a coverage question and is preserving its right to deny the claim later if the investigation supports that. Read it carefully to see which issues the insurer has identified, and consider talking to an attorney if a significant amount is in dispute.
Appraisal
If both sides agree the damage is covered but disagree on the dollar amount, most homeowners policies include an appraisal clause as an alternative to a lawsuit. Either party can invoke it in writing. Each side hires its own independent appraiser, and if the two can’t agree, they pick a neutral umpire. A decision supported by any two of the three is binding on both sides.
Public Adjusters
A public adjuster is a licensed professional who works for you, not the insurance company, to prepare and negotiate your claim. They are most useful on large or complex losses where the insurer’s first offer looks too low. Fees typically run 5 to 12 percent of the final settlement, with 10 percent standard, and come out of your recovery because your policy does not pay for them. Negotiate the fee before signing anything, and confirm the adjuster is licensed in your state.
Watch Out for Storm-Chasing Contractors
After any storm damage, unsolicited repair offers are common and often predatory. Warning signs include:
- Demands for large upfront payments or cash and wire-transfer-only terms. Legitimate contractors don’t require full payment or unusually large deposits before starting.
- No written contract, no proof of insurance, no valid local license.
- Pressure to sign immediately, often framed as supplies running out or losing your place in line.
- An offer to waive your deductible, which usually means the estimate is being inflated to cover it. That is insurance fraud.
Get at least two or three written estimates from licensed, insured contractors before committing. Your insurer may keep a list of vetted repair professionals in your area.
Reducing the Risk Next Time
A professionally installed lightning protection system is the most direct defense. Metal air terminals on the roof connect through heavy conductors to grounding rods in the earth, intercepting the bolt and giving it a safe path around the structure. The system does not prevent lightning from striking the house; it redirects the energy. To be effective, it must meet NFPA 780 and carry a UL Master Label. Some insurers offer premium discounts of 5 to 15 percent for homes with a certified system.
A whole-house surge protector installs at your main electrical panel and absorbs voltage spikes before they reach your wiring and appliances. These run roughly $70 to $700 installed and work well against indirect strikes and utility surges, though no surge protector can guarantee complete protection from a direct hit. Pair it with point-of-use strips on sensitive electronics. Proper grounding of the whole electrical system is what makes any of this work.
If your home has CSST gas piping, confirm it is bonded to your electrical grounding system as the code requires.2Lightning Protection Institute. NFPA 54 To Include Bonding Requirements Older installations may not meet current standards. A licensed electrician or plumber can verify the bonding and add it if needed, and the job is inexpensive compared to the risk it removes.
