When a drone is useful
A drone is most useful where a roof is high or hard to reach, where scaffolding is not in place, and where a client needs visual documentation of roof coverings and high-level details. It allows detailed imagery of areas that would otherwise be difficult or impossible to see safely from a single visit.
We use drone imagery as one tool within a broader inspection. It is not a substitute for physically assessing what can be reached, and we are clear in the report about which findings come from aerial imagery and which from physical inspection.
What a drone can assess
- Roof coverings — slates, tiles and membranes — and their general condition and alignment.
- Ridge lines, hips and valleys.
- Chimney stacks, pots, pointing and flaunching.
- Flashings and leadwork at junctions and abutments.
- Parapets, gutters and flat-roof areas.
- Overall roof form and any visible defects or displacement.
What a drone cannot do
A camera cannot probe beneath surfaces, test the integrity of fixings, lift coverings, or assess the roof structure from within. It documents what is visible from the air. Where these limits matter — for example where a defect may be hidden beneath a covering — we combine drone imagery with a physical inspection of accessible areas and, where relevant, the loft space.
Weather, airspace and safety
Drone flights are subject to weather conditions, legal airspace restrictions, and safety considerations. High winds, rain and poor light can prevent a useful flight, and parts of London fall within restricted airspace or close to it. Some locations cannot be flown safely or legally. We assess this for each property and will tell you in advance if a drone is not suitable for your address.
Privacy considerations
Drone flights capture imagery of the surrounding area as well as the subject property. We operate with regard to privacy, focus imagery on the property being inspected, and do not publish or share imagery beyond the report. Neighbouring properties are not the subject of the survey.
Drone inspection versus physical inspection
The two are complementary. A drone gives excellent visual coverage; a physical inspection gives depth — testing, probing and internal access. For most surveys we use both where appropriate. See also our roof condition survey and pre-purchase roof survey pages.
