Know what the data means

Satellite measurements show size. An onsite inspection shows condition.

Learn what satellite roof measurements can estimate, what they cannot reveal, and why an onsite inspection is needed for roof condition findings.

Short answer

Satellite imagery can help estimate roof dimensions, surface area, pitch, and geometry when data is available. It cannot confirm leaks, concealed damage, fastening, underlayment, or every field condition. GenRoof uses satellite data to improve quoting and preparation, then relies on the onsite inspection for condition observations.

What satellite data may provide.

  • Property match and roof outline
  • Estimated surface area and footprint
  • Estimated pitch or geometry
  • Image date or quality indicators when supplied by the provider

What it cannot establish.

  • Whether a ceiling stain is actively leaking
  • The condition of concealed underlayment or decking
  • Fastening, attachment, or hidden installation details
  • Every crack, lifted edge, puncture, sealant condition, or drainage issue
  • Code compliance, engineering adequacy, or insurer acceptance

Why a property may need manual review.

Trees, shadows, old imagery, additions, multiple structures, unusual geometry, and provider coverage can limit the estimate. If the data is not good enough, the property should be reviewed before a price is accepted.

How GenRoof uses the estimate.

The estimate helps select a preliminary price tier and prepare the field visit. It is not presented as the inspection itself. The onsite professional confirms the property, access, visible conditions, and any measurement needed within the booked scope.

Common questions

Straight answers before you book.

Is a satellite roof measurement exact?

No. It is an estimate affected by source imagery, roof geometry, obstruction, and provider coverage.

How recent is the imagery?

The available image date should be shown when the provider supplies it. It may not represent the roof today.

Can trees block the roof?

Yes. Heavy tree cover and shadows can reduce measurement confidence or require manual review.

Can satellite data detect a leak?

No. A satellite measurement does not diagnose a roof leak or concealed moisture.

What happens when no satellite data is available?

GenRoof can route the property for manual review before confirming the scope or price.

Will the report show the measured roof?

The final report format and included measurement exhibits are confirmed as part of the booked scope.
