A drone roof survey uses aerial photography or video to inspect roofs, chimneys, guttering and other high-level areas that may be difficult to view clearly from the ground. The imagery can reveal visible defects and provide useful evidence without immediately requiring scaffolding or roof access.

Subject to suitable flying conditions, a drone may be used to inspect roof tiles or slates, flat roof coverings, ridges, valleys, verges, lead flashing, chimney stacks, parapets, guttering, roof junctions and high external walls. It is a visual inspection, so concealed defects may require further investigation.

A drone survey can help identify visible external defects that may be contributing to penetrating damp or rainwater ingress. The aerial imagery should be considered alongside internal staining, moisture patterns and other inspection findings. A photograph of an external defect alone may not confirm the complete cause.

Scaffolding is not normally required for the initial drone inspection. This can make it easier to obtain a detailed view of high-level areas before arranging more extensive access. Scaffolding, ladders or other equipment may still be required if a defect needs physical examination or repair.

No. A drone survey provides detailed visual evidence, but it cannot lift roof coverings, test fixings or inspect concealed construction. If the imagery identifies a possible defect, closer physical access or targeted opening-up may still be recommended.

No. A flight depends on suitable weather, visibility, airspace, surrounding people and property, and a safe area for operating the drone. The property and site conditions should be checked before flying. If conditions are unsuitable, the survey may need to be rearranged or an alternative inspection method considered.

The photographs or video are reviewed for visible defects affecting the roof, chimney, guttering or other high-level areas. Where the survey forms part of a damp investigation, the aerial findings are compared with the symptoms inside the property. Damp Doctor Sussex then explains the findings and recommends an appropriate next step.

Yes. Drone surveys may be suitable for houses, flats, residential blocks, commercial buildings and older properties with difficult-to-reach roofs or elevations. Suitability depends on the building, location, surrounding area, access and flight conditions.
