Early-Stage Roof Condition Review for a Facilities Management Project in Worcester
Project background
A nationwide facilities management and maintenance company was responsible for assessing the condition of a complex roof arrangement on a property in central Worcester. The site formed part of a wider portfolio and required an initial condition review to support refurbishment pricing and maintenance planning.
The building presented several practical constraints. Roof areas were arranged across multiple levels, with parapet walls and edge details limiting visibility from ground level. The property was located in a built-up area, where temporary access solutions would have required additional coordination and oversight.
At this stage, the client did not require a full intrusive inspection. The immediate requirement was to obtain sufficient visual information to understand general roof condition and identify whether further investigation or access equipment would be justified.
Constraints and access considerations
Traditional inspection methods were reviewed but not progressed at this stage. Scaffolding would have introduced cost, programme implications, and disruption to the surrounding area. Mobile access equipment would still have provided limited coverage of certain roof sections and would have required on-site supervision.
The absence of an on-site facilities team also meant that any access solution would need to be carefully timed and managed. For an early-stage assessment, this level of coordination was not considered proportionate to the information required.
Survey approach
A non-intrusive drone survey was selected to capture visual information across the roof areas without physical access. The objective was not to carry out a detailed condition survey, but to obtain clear, high-resolution imagery of roof coverings and associated elements that could be reviewed remotely.
The flight was planned to achieve comprehensive visual coverage of the roof layout, including perimeter edges, changes in level, and interfaces between different roof sections. Particular attention was paid to areas that are typically difficult to assess from ground level or via limited access.
The survey was completed with minimal time on site, and no interruption to building operations.
Scope of imagery captured
The drone imagery provided visual records of the following elements, where visible:
Flat and pitched roof coverings and their general surface condition
Parapet walls, coping details, and roof edges
Junctions, upstands, and transitions between roof sections
Rainwater outlets, gutters, and visible drainage routes
Localised defects or areas of deterioration apparent at the time of survey
The imagery was reviewed as a visual reference only. No physical testing, opening up, or confirmation of concealed construction was undertaken.
Use of the survey information
Following completion of the survey, the imagery was issued to the client for internal review. This allowed facilities and maintenance teams to examine roof areas remotely and discuss condition without the need for a site visit.
The visual information was used to:
Support refurbishment and maintenance pricing exercises
Identify areas where further inspection might be required
Prioritise sections of the roof for future investigation
Decide whether access equipment or intrusive surveys were justified at a later stage
This approach allowed decisions to be made based on current visual evidence, rather than assumptions or incomplete views from ground level.
Outcome
The drone survey provided a practical overview of roof condition for this site, sufficient to inform early-stage planning and pricing decisions. By deferring physical access until it was clearly required, the client was able to reduce unnecessary preliminary costs and limit disruption at this stage of the project.
The survey outputs formed part of the client’s wider decision-making process and were used alongside existing records and maintenance information.

Limitations
This survey was limited to a visual assessment based on drone imagery captured at the time of flight. No comment is made on concealed elements, internal construction, or areas not visible due to access or line-of-sight constraints.
Where defects are suspected, or where refurbishment works are proposed, further investigation using appropriate access methods may be required.
