Roof inspections & maintenance · A focused guide
What can drone photographs leave unanswered about a roof?
Published by Big Ben Roofing Ltd
Overhead images can show visible roof areas, but they do not independently explain every cause or concealed condition. Ask what specific question the images address, who interprets them and whether internal evidence or closer inspection is also needed. RICS stresses the role of professional interpretation alongside survey technology. A large photo folder should therefore be accompanied by located observations and clear limitations, rather than being treated as a diagnosis because it contains detailed aerial views.
Define the evidence you actually need
A picture of a missing tile may help locate a defect, while recurring indoor water may need additional information about the roof space and junctions. Ask the provider which areas could not be viewed clearly and whether the chosen method suits the property. If aerial photography is proposed, confirm who provides it, what interpretation is included and whether relevant internal observations also form part of the agreed service.
Request an interpreted record
Ask for labels connecting significant images to elevations or roof sections, with findings separated from possibilities requiring investigation. Retain original images where provided, but use an organised summary when comparing repair scopes. A marked image can explain the work boundary; it cannot demonstrate concealed layer condition by itself. If further access is recommended, ask what unresolved question it is intended to answer before commissioning a second stage.
Useful details to record
- State which roof question the images should answer.
- Ask who interprets and labels significant observations.
- Record unclear views and concealed inspection limits.
- Link any further visit to an unresolved finding.
Use information already available from indoors or ground level. Do not climb onto the roof or disturb materials to complete this checklist.
Does a high-resolution aerial photograph establish why a tile moved?
It may show displacement without revealing the fixing or support behind it. Ask which evidence supports the proposed cause and whether additional inspection is required, rather than treating image detail alone as confirmation of the underlying defect.
Background reading
General guidance helps frame the questions. The cause, suitable materials and scope depend on inspection of the particular roof.
