How Drone Technology Is Changing Building Surveys

Roofs, chimneys, parapets and high-level guttering can be impossible to inspect properly from the ground. Traditionally, gaining access often meant scaffolding, cherry pickers or working at height – all of which take time, add cost and introduce additional risk.

For building surveyors, drones have become a genuinely useful tool. They allow us to inspect parts of buildings quickly, safely and in impressive detail. High-resolution photographs and video can be captured in minutes, providing a clear visual record of areas that might otherwise remain unseen.

The results are not just helpful for surveyors. They are valuable for property owners too, giving them a much clearer understanding of the condition of their building.

Why Drones Work So Well for Building Inspections

Every building is different, and not all of them are easy to inspect.

Industrial premises often have complex roof layouts, with multiple levels, plant equipment, skylights and service runs. Access points can be restricted, and some areas simply can’t be viewed from ground level.

Similarly, many modern residential developments are now constructed over three storeys, often with flat roofs at the highest level. Without specialist access equipment, inspecting those areas thoroughly can be extremely difficult.

This is where a drone comes into its own.

From the air, we can capture detailed images of things like:

• roofing materials
• flashing
• chimneys
• gutters

Those images can then be reviewed carefully as part of the survey process, stored on file, as well as shared with clients.

Seeing a defect clearly rather than reading about it in a report is really helpful.

Recent Projects Where Drone Surveys Made a Real Impact

Our drones have been used on a wide range of projects recently, helping us inspect buildings that would otherwise have been difficult to assess properly.

Supporting a Local School with Long-Term Maintenance Planning

One recent instruction involved working with a school in Beaconsfield that wanted a clearer picture of the condition of its buildings.

Schools often have large roof areas and multiple structures spread across a site, making access challenging. Using the drone, we were able to carry out detailed inspections of roofs and chimneys across the property.

The imagery gathered during the inspection allowed us to assess the condition of key elements and identify areas needing attention. That information then formed the basis of a planned maintenance schedule we put together, helping the school prioritise works and budget more effectively for the future.

Inspecting Industrial Buildings with Limited Access

Industrial units present their own challenges. Roofs are frequently large and difficult to access safely.

On several recent instructions in Amersham, drones allowed us to inspect industrial properties where the building design and restricted access points meant that ground-level inspection alone would have left important areas unseen.

With the drone footage, we could review roofing materials, check the condition of gutters and flashings, and identify defects without the need for costly access equipment.

Surveying Modern Residential Developments

Another common use is inspecting modern residential buildings constructed over three storeys.

Many of these developments have flat roofs at the highest level, and the design often makes physical access impractical. Without a drone, surveying these areas properly would require specialist equipment or scaffolding.

The drone allows us to review those roofs quickly and safely, capturing detailed images that can be analysed later as part of the survey.

Discovering Hidden Chimney Problems

On one project, we were asked to inspect a pitched roof following concerns about the condition of the roof tiles and mortar. The drone allowed us to examine these areas closely, but the higher vantage point revealed something else entirely.

From the ground, the chimneys had appeared to be in reasonable condition. However, the drone footage showed extensive disrepair to the chimney stacks that was not visible from below.

Without that aerial inspection, the issue might easily have gone unnoticed until it developed into a more serious problem.

A Clearer Understanding of a Building’s Condition

As Building Surveyor Philip Pearcey explains:

“Having the drone means I can inspect areas of a building that were previously very difficult to access. The high-quality images and video we capture give us – and our clients – a much clearer understanding of the building’s condition and help identify any issues.”

Clients can see exactly what we are seeing.

Instead of relying solely on written descriptions, they have a visual record of the building’s condition. That makes it easier to understand the issues, plan repairs and prioritise maintenance work.

A Practical Tool That Improves Safety and Efficiency

Drones are not a replacement for traditional surveying skills. But we are finding that they are an excellent addition to our team’s toolkit.

They improve safety by reducing the need for working at height. They make inspections more efficient. They provide clear, detailed imagery that supports better decision-making.

For our surveyors, that means more thorough inspections. For property owners, both commercial and residential, it means better information about the buildings they are responsible for.
