A home insurance application asks about a roof's age and material, but many insurers no longer rely on the application alone. Understanding how insurers use aerial imagery to assess your home helps explain why a renewal can arrive with a question about a roof that nobody has visited in person.
This article covers one topic: aerial imagery in home insurance, meaning what it is, what it can and cannot show, and how it can factor into underwriting and renewals. It is general information about industry practice, not a description of how any specific insurer uses it.
What Is Aerial Imagery in Home Insurance?
Aerial imagery in home insurance is the use of high-resolution photographs taken from aircraft, drones, or satellites to review the exterior of a property as part of assessing it for insurance. The images are often analyzed automatically by software that looks for features such as roof shape, material, and visible wear.
Property analytics providers now offer this at scale. CAPE Analytics, for example, reports roof condition ratings available for more than 120 million homes and commercial properties across the United States and Canada. For insurers, imagery offers a view of a property's exterior without sending an inspector to every address. Images are typically refreshed on a cycle, so the picture an insurer sees may be months or even a few years old, depending on the provider and the area.
What Aerial Images Can Show an Insurer
Depending on resolution and how recently they were captured, aerial images can show a range of exterior features:
- Roof characteristics. Shape, approximate material, and visible condition, such as staining, patching, debris, or missing shingles.
- Trees and vegetation. Branches overhanging the roof or dense vegetation close to the structure.
- Structures on the property. Detached garages, sheds, decks, and pools.
- Surroundings. Nearby hazards or features that can matter for property risk.
Many analytics tools translate these observations into a structured output, such as a roof condition score, that an underwriter can review alongside the application.
How Aerial Imagery Can Factor Into Underwriting and Renewals
Imagery is generally one input among several rather than a decision on its own. Insurers combine it with the information on an application, claims history, and other data when assessing a home, as described in how home insurance premiums are calculated in Canada.
When an image suggests a roof may be older or worn, an insurer may respond in different ways depending on its guidelines: asking for more information, requesting photos or an inspection, adjusting a deductible, or setting a condition at renewal. For homeowners, a renewal question about a roof is often the first sign that imagery was part of the review. Roof material matters in other ways too, as covered in how hail-resistant roofing can affect home insurance premiums.
What Aerial Imagery Cannot Show
Imagery has real limits. It shows only the exterior, and only as of the day the image was captured. It cannot show a home's wiring, plumbing, heating system, or interior condition, and an image taken before a roof replacement can make a new roof look old.
Shadows, snow cover, and tree canopy can also affect what an image appears to show. Consumer advocates and some regulators outside Canada have raised concerns about decisions based on outdated or misread images, which is why dated evidence of recent work, such as invoices and photos, is often useful context for an insurer.
How Imagery Questions Are Commonly Handled
When an insurer raises a question based on imagery, the conversation usually follows a familiar pattern. The insurer describes what it saw or what information it needs, such as the roof's age, material, or condition. The homeowner, often through their broker, then provides information the image may not reflect.
Information that is commonly useful in these conversations includes:
- Invoices and permits for a roof replacement or repair, showing the date and scope of the work.
- Dated photos of the roof and exterior, especially after recent work.
- Contractor details, such as the installer and the materials used.
- Maintenance records, such as tree trimming near the roof or gutter repairs.
Some insurers also arrange their own inspection, either in person or through photos submitted by the homeowner. How an insurer weighs this information is set by its own underwriting guidelines, and a licensed broker can explain what a specific insurer is asking for and why.
Benefits of Understanding Aerial Imagery
Understanding that insurers may review a home from above helps a homeowner make sense of renewal questions that would otherwise seem to come from nowhere. It also highlights the value of keeping records: invoices, permits, and dated photos of a new roof or other exterior work give an insurer information an image cannot.
Imagery can also work as an early warning. A question about a roof's condition can prompt a homeowner to look at a problem before it turns into water damage inside the home, which is generally far more disruptive and costly to repair than roof maintenance.
Finally, knowing that imagery is one input among many puts it in perspective. An image is a starting point for a conversation between the homeowner, the broker, and the insurer, not a final judgment about the home.
Where You'll Come Across Aerial Imagery
Aerial imagery tends to come up at a few predictable moments: when applying for a new home insurance policy, at renewal when an insurer asks about a roof's age or condition, after replacing a roof when the insurer's records may not yet reflect the change, and when an insurer requests photos or an inspection of the exterior.
Talk to a Licensed Broker About Your Home
Every insurer uses imagery and other data in its own way, and only a licensed broker working with actual policies can speak to a specific home. A licensed MyBrokers broker can explain a renewal question about a roof and help share the right information with an insurer. Start a home insurance quote to talk it through.
Coverage details vary by insurer and by policy, and only the wording of an actual policy and a licensed broker can confirm what applies to a specific situation.
