Aerial and satellite imagery can make a thin property file easier to question. It can show that the visible building footprint, roof geometry, site access, or nearby exposure does not match the submitted description. It cannot, by itself, confirm every construction or condition detail.
Use imagery as review evidence and a source of follow-up questions, not as a substitute for an inspection.
Confirm that you are viewing the right property
Before interpreting the image, check the address match, parcel outline, building footprint, and surrounding roads. Corner lots, multi-building campuses, condominiums, rural parcels, and recently subdivided sites can all create mismatches.
If the property contains several structures, identify which building the submitted values describe. A parcel-level image may be correct while the assumed subject building is not.
Keep the provider, capture date, and image type with the review when available. A current basemap label does not mean the underlying image is current.
What imagery can help you review
Depending on resolution, angle, season, and obstruction, imagery may help with:
- visible building footprint and number of structures;
- broad roof shape and roof sections;
- roof-mounted equipment and some surface changes;
- additions, detached buildings, or site development;
- vegetation and defensible-space context;
- distance and orientation to nearby structures;
- access roads, parking, yard storage, and water adjacency; and
- apparent differences from older records or diagrams.
These observations can guide triage. They should be stated in terms of what is visible, not what the reviewer assumes from it.
What imagery usually cannot confirm
An overhead image generally cannot establish concealed construction, interior occupancy, structural integrity, sprinkler operation, electrical condition, exact roof assembly, or compliance with a code or maintenance standard.
Color alone is not a dependable basis for identifying roof-covering material. Shadows can distort height and distance. Trees, snow, cloud cover, image stitching, and low resolution can hide or alter features.
Street-level imagery can add facade and occupancy context, but its capture date and field of view still matter. Neither overhead nor street-level imagery proves that a visible feature remains unchanged today.
Review the roof without overreading it
Begin with features that can be described consistently: roof shape, number of planes, visible penetrations, rooftop equipment, drainage patterns, and apparent patching or section changes.
Then compare the image with submitted roof age, covering, and permit history. A visible color change may support a question about replacement or repair, but it does not establish the installation date or material. A permit record may add context, but it also needs its own status and scope reviewed.
If roof detail is important to the placement, seek inspection photographs, invoices, permits, or a roof report rather than treating the aerial view as conclusive.
Review nearby exposures in context
Measured distance is more useful when paired with an explanation of what was measured. Record whether the distance runs from wall to wall, footprint to footprint, parcel boundary to structure, or another reference point.
Look beyond the nearest building. Relevant context may include attached structures, shared walls, vegetation, outdoor storage, fuel tanks, rail lines, waterways, steep slopes, and access constraints. Which exposure matters depends on the occupancy and peril being reviewed.
An image can show spatial relationships. It does not establish another property’s operations, fire load, ownership, or hours of use.
Compare imagery with the rest of the file
Imagery becomes more useful when it is reviewed beside the SOV, assessor data, permits, inspection material, and property diagram.
Flag specific discrepancies, such as:
- the image appears to show two buildings while the SOV lists one;
- the visible footprint differs materially from the reported area;
- a roof section appears different from the submitted roof description;
- an addition appears in later imagery but not in the property record; or
- nearby structures or vegetation are absent from the submission narrative.
Avoid writing “data is wrong” when the evidence only shows a difference. The right next step is to identify what would resolve it.
Create a repeatable imagery note
A useful note records:
- the property or building reviewed;
- imagery provider and capture date, when available;
- visible observations;
- obstructions or quality limits;
- conflicts with submitted or sourced fields; and
- the recommended follow-up.
Use neutral language such as “appears,” “visible,” and “not visible in this image.” Those terms are not evasive. They accurately distinguish observation from confirmation.
Know when to escalate
Request better evidence when an observation could materially affect the underwriting review and the image cannot resolve it. Depending on the question, that may mean current ground-level photographs, an inspection, measurements, invoices, permit documents, or clarification from the insured.
For a field-level approach to conflicting evidence, see how to review property data sources, dates, and confidence. The objective is a clearer first read and a focused request for missing evidence, not a remote inspection disguised as certainty.
Keep imagery observations next to their source and capture date. The sample report reading guide explains how to carry source context and unavailable dates into a useful reviewer handoff.
The U.S. Geological Survey’s imagery guidance identifies capture date, season, resolution, and scale as factors that affect how useful imagery is for locating structures. Record the metadata that is available for the image you reviewed.
