Drone roof surveys in Lewisham
We are based in SE12, so Lewisham is on our doorstep. Close-up drone and thermal surveys of roofs, chimneys, gutters and facades across the borough, from single houses to schools and estates.
Buildings we inspect across Lewisham
Victorian and Edwardian terraces
Slate and tile roofs, chimneys, valleys and back additions across Lee, Hither Green, Brockley, Catford and Forest Hill.
Schools
Long pitched and flat roofs where leaks keep coming back and the whole roof needs recording before repairs are planned.
Estates and blocks
Flat roofs, outlets and parapets on housing blocks, checked without scaffold or roof access.
Houses with a leak
A quick drone check of tiles, flashings, chimney and gutters, so you know what the roofer is quoting for.
Recent work near Lewisham
Our school roof case study in Lee, SE12 is on the Lewisham and Greenwich border. Around 1,500 visual and thermal image pairs showed defects along most of the 61 m roof, not just where it had leaked, and about 290 m² of repair zones were measured from the imagery.
Airspace and permissions
We check every Lewisham address against the airspace map before we fly and arrange any permission needed, so the survey day runs to plan.
How a survey works
Send us the address and what you need to know. We check the airspace, plan the flight and confirm the day. On site we use a small take-off area, fly close overlapping runs over every roof plane and elevation, and capture thermal images where they help. AI defect detection runs across the imagery and an experienced inspector checks and grades every finding before it goes into your report.
Do you cover all of Lewisham?
Yes. We cover the whole borough, including Lee, Hither Green, Lewisham, Catford, Brockley, Deptford, New Cross, Sydenham and Forest Hill.
Can you just check one roof?
Yes. Single houses are welcome: a quick drone check of the roof, chimney and gutters with close-up photos and a short report.
Is it legal to fly a drone over buildings in London?
Yes, when it is done under the right authorisation. 901 Aerial Surveys flies under a CAA operational authorisation (PDRA01), which covers commercial flights close to people and buildings. Much of London sits inside controlled or restricted airspace, so we arrange any permissions needed before the day.
Do you need access to my property?
Usually only a small, controlled take-off area, such as a car park, garden or a quiet stretch of pavement. Nobody needs to go onto the roof or into the building for the inspection itself.
