Measure Any Roof.No Ladder Needed.
Measure any roof on aerial imagery right inside Drodat. Map each roof section and set its pitch, and Drodat calculates every section's area, the total roof area, and the total edge length, then saves the report to the property. No more waiting on third-party providers.

How Roof Measurements works
Measure the roof without leaving the claim
Open the property
High-resolution aerial imagery for the address loads automatically, with past capture dates you can switch between.
Create a dimension report
Choose Create New Report and map each roof section on the image, in a 2D or 3D view.
Set the pitch
Give every section its pitch, such as 4/12. Section areas and roof totals update as you work, with undo and a metric or imperial toggle.
Generate the report
Review the measurements and generate the report. It is saved under Dimension Reports on the property, next to every earlier version.
What's in every report
- Total roof area
- In square feet or square meters
- Roof sections
- Each section with its own area and pitch
- Total edge length
- Combined length of every roof edge
- Imagery
- Measured on the aerial imagery for that address
- Version history
- Every report kept on the property
- Where it lives
- On the property, with a Roof Report folder in its cloud drive
Check the estimate
Compare your measured roof area with the carrier estimate before you sign off on a number.
Compare estimates with Dex AIProve the roof before the loss
Step back through past capture dates to show the roof was intact before the storm.
See historical aerial imageryShow the roof’s real age
A re-roof permit shows when the roof was replaced, which sets the age the carrier can depreciate.

Frequently asked questions
Drodat Roof Measurements is a roof measuring tool built into the Drodat claims platform. You measure a roof on aerial imagery of the property, and Drodat calculates the area and pitch of each section, the total roof area, and the total edge length, then saves a measurement report to the property.
Open the property, choose Create New Report under Dimension Reports, map each roof section on the aerial image, and set its pitch. Drodat totals the area as you go. When the measurements look right, generate the report.
Each report includes the total roof area, every roof section with its own area and pitch, the number of sections, and the total edge length. Reports are saved on the property, so earlier versions stay available.
No. You create roof measurement reports yourself inside Drodat, from the aerial imagery of the property, so there is no outside order to wait on.
Yes. The measuring tool switches between imperial and metric units, so roof area can be shown in square feet or square meters.
Roof measurement reports are created in the Drodat web app, on the property page. Each report is saved to the property, alongside its aerial imagery, permits, and weather history.
