Aerial imagery: how insurers inspect roofs from the sky

Many insurers now look at your roof without sending anyone: they buy or capture high-resolution photographs from aircraft, satellites and drones, run software over them and score the roof's condition, material and surroundings. The images can support a discount, a repair request or a nonrenewal, and they are sometimes wrong. Regulators in several states have said an image alone is a weak basis for dropping a policy, and a homeowner who disputes one with evidence often wins.

How the images get used

Aerial imagery enters the insurance process at four points.

• Quoting and underwriting. The insurer pulls an image for your address to confirm roof shape, material and apparent condition, nearby trees and structures, and features such as a pool or trampoline. Data vendors package this as a property report. Moody's said in January 2025, when it agreed to acquire the property-analytics firm CAPE Analytics, that nearly half of the 50 largest U.S. property insurers used CAPE's tools in pricing and underwriting (Moody's).
• After binding. A new policy may be re-checked against imagery in the first weeks; see insurance inspections after you buy a policy.
• At renewal. Portfolio reviews rerun images across thousands of policies and flag roofs that look worn, patched or tarped, or houses with branches over the roof.
• After a storm. Insurers use imagery to see where damage is concentrated and to decide which claims need a field visit.

Software does the first pass. A person usually reviews flagged files, though how closely varies by company, and the NAIC and states are working on rules for automated decisions; see AI in home insurance: the rules on underwriting and claims.

What the pictures can and cannot tell

An image is a single moment, from above, at a resolution the vendor chose. It is good at some things and poor at others.

Roof age is the point many homeowners miss. The image cannot tell a 12-year-old roof from a 22-year-old one in similar condition, so the insurer relies on what you told it, permit records or a vendor's estimate. If any of those are wrong, the "old roof" label can follow you.

What states have done

The practice is legal, and regulators have mostly said so. What they have addressed is accuracy and process. The rules below come from bulletins and statutes of different strength. Check your own state's department of insurance, because this area is changing fast.

Pennsylvania's department said it did not intend to restrict aerial imagery broadly. The common thread across these states is that an image can start an inquiry but should not be the last word.

Signs your insurer used an image

You may never be told. Look for these:

• A nonrenewal or conditional renewal letter that cites "roof condition," "debris," "overhanging trees" or "unrepaired damage," and no one visited.
• A repair deadline with no inspection report attached.
• A request for a roof certification after years without one.
• A premium or deductible change at renewal tied to a "property condition" or roof-age field.

If an image is the reason

1. Read the letter for the specific finding and the date. "Roof condition" is not a finding. Ask which feature, on which slope.
2. Request the image and any report in writing, including the date captured and the vendor. In states that require disclosure you are entitled to it; elsewhere, ask anyway.
3. Photograph the roof yourself, every slope, with date stamps, plus close-ups of whatever the insurer cited. Do it from a safe vantage point or hire someone; do not climb a steep roof.
4. Get a written roof condition report from a licensed roofer. A line such as "no active leaks, shingles serviceable, estimated remaining life of X years" answers a condition finding more directly than photographs do. If the issue is moss or algae, a cleaning invoice helps.
5. Send everything before the deadline, by a method that leaves a record, and ask for the finding to be re-reviewed by a person and for a written decision.
6. Raise the rules. If your state has a bulletin or statute on imagery, cite it by number in your letter. See how to file a complaint with your state insurance department if the insurer does not respond.
7. Keep a replacement option open. nonrenewal vs cancellation of homeowners insurance: your rights explains the notice periods that apply, and the nonrenewal action plan lays out the shopping steps while the dispute runs.

A hypothetical dispute

Say your insurer mails a nonrenewal notice citing "roof deterioration visible in aerial imagery." You ask for the image and learn it was taken 20 months earlier, after a wet spring. A roofer inspects, finds algae streaking and no granule loss, writes a one-page condition report and cleans the north slope. You send the report, the invoice and dated photos with a letter asking that the nonrenewal be rescinded. The insurer reviews and withdraws it. You should not count on that result, which depends on the facts, the insurer's guidelines and your state's rules, but the documentation is what gives the request a chance.

Staying ahead of the camera

• Tell the insurer when you replace the roof. Send the invoice and permit so the file shows a new roof before the next image run, and so you qualify for any roof-age credit.
• Trim branches off the roof and keep valleys and gutters clear.
• Remove tarps promptly after a repair; a tarp in an image looks like unrepaired damage.
• Keep dated photos and invoices for the roof every year or two. See roof inspections: what insurance inspectors look for for what a proper roof inspection documents.
• Know your insurer's roof-age rules (roof age limits: when insurers won't cover an old roof) so a letter does not come as a surprise.

Key takeaways

• Insurers use aircraft, satellite and drone images to judge roof condition and surrounding hazards at quote, after binding, at renewal and after storms.
• Images cannot show roof age and often confuse algae, moss, shadows and debris with damage; a roofer's written report is the best rebuttal.
• Pennsylvania, West Virginia and Tennessee regulators have said imagery should not be the only basis for action, and Louisiana law limits reliance on images older than 24 months.
• Ask in writing for the image, its date and the specific finding, and respond before the deadline.
• Send your insurer the invoice when you replace a roof, and remove tarps and limbs so the next image shows the real condition.
