4K drone roof inspections for commercial buildings across London and the South East. Detailed defect reports without scaffolding costs or working at height risks — delivered within 48 hours.
Drone Surveys
A drone roof survey gives you a complete, high-resolution view of your commercial roof without scaffolding, cherry pickers or any disruption to your operations. For large industrial roofs, multi-bay warehouses and buildings where physical access is difficult or expensive, it's the fastest and most cost-effective way to get an accurate picture of the roof's condition.
Exall Group operate CAA-compliant drone surveys across London, Essex, Surrey, Kent and Hertfordshire. Our pilot handles all flight planning, airspace permissions and risk assessments before arriving on site — there's nothing for you to arrange. We capture 4K aerial footage and high-resolution photography of every section of the roof, identifying cracking, ponding, failed flashings, damaged membranes and sealant failures that would be difficult to spot from ground level.
The survey report includes annotated 4K imagery, a condition summary for each roof area and prioritised recommendations for any works required. Reports are delivered within 48 hours of the site visit.
Drone surveys work particularly well alongside our condition surveys — combining aerial coverage with a physical inspection for a complete roof assessment. Where active leaks are suspected, we can also pair a drone survey with our electronic leak detection service to pinpoint the source precisely.

Frequently Asked Questions
Most commercial drone surveys are completed within 2-4 hours depending on the size of the building. You'll receive your full report with annotated 4K imagery within 48 hours.
In many cases it's more accurate. Our 4K cameras capture detail that's difficult to spot from scaffolding or cherry pickers. We can identify cracking, ponding water, failed sealant, damaged flashing and membrane defects from the imagery.
No — that's the main advantage. Drone surveys eliminate the need for scaffolding, cherry pickers or roof ladders, removing both the cost and the health and safety risk of working at height.
We hold all necessary CAA permissions for commercial drone flights. We handle all flight planning, risk assessments and airspace permissions before attending site. Some locations near airports or in restricted zones may require additional clearance, which we manage for you.

Drone surveys are excellent for identifying areas of ponding water, damaged membranes and failed sealant joints that are common causes of leaks. For pinpointing active leaks beneath the membrane, we recommend pairing a drone survey with our electronic leak detection service.
It's helpful but not essential. We just need access to the property and a safe area to operate from. We'll coordinate everything with you or your facilities team in advance.
