Leak detection and inspection solutions for roofs and façades, single ply, felt, flat, green, metal, pitched, cladded, tall or challenging to access in London, Birmingham, Manchester, Brighton and across the UK.

Building Transformation offers flexible leak detection services for commercial and residential properties. Hidden leaks left untreated develop into serious structural issues down the line, requiring expensive and disruptive repairs.
Therefore, it’s recommended to conduct regular leak detection processes in a property to ensure there are no hidden leaks. We offer cost-effective roof leak detection services to determine if there is a leak in your property. Should we find one, we offer appropriate solutions for how to best fix the problem.
Using a team of experienced technicians equipped with the latest leak detection equipment, our process aims to detect leaks before they cause significant damage. We also offer dry run testing to determine the integrity of newly built flat roofs.

Why You Need a Roof Leak Detection

Whether a commercial or domestic property, the roof of a building plays a vital structural role. It keeps out precipitation and moisture, ensuring there are no leaks or damp developing inside the roof and building.
However, as roofs are at the constant mercy of the elements, there are naturally going to deteriorate over time. This could be minor cracks and splits on the roof membrane or serious structural damage causing huge leakages inside the roof and building.
In either case, a roof leak detection is designed to detect the presence of leaks, allowing quick and efficient solutions to be made. For example, flat roof leak detection typically finds damage to roof membrane materials as the main cause of the leaks, with repairs or replacements being the necessary solution.
Moreover, roof leak detection services are great for preventative maintenance. By scheduling regular roof leak surveys, minor issues can be detected before leaks appear. This allows you to avoid more costly repairs from hidden leaks that develop into huge problems down the line.

Our Roof Leak Detection Process

We use a dry run testing method for flat and low pitched roofs. This electronic equipment quickly identifies any damage or imperfections to the membrane material – the most common cause of leaks.
Because the equipment is fast and efficient at detecting leaks, we identify minor imperfections long before they develop into a serious structural leak. Small punctures and splits that can normally be missed during an inspection are easily identified, allowing fast action to avoid leaks.
Our technicians come with full accreditation and licencing, ensuring compliance with all current on-site health and safety regulations. The process is quick and non-disruptive, while being suitable flat roofs new and old.
The process does not require any removal or disruption of the current roof membrane, so if we don’t find any leaks, no repairs to the membrane are required.
Once the dry run roof inspection is complete, we provide a detailed report on our findings. These are forthright about the exact conditions of the roof, including any possible risks and recommended solutions.

    Beautifully designed and intelligently engineered building façades fail over time. Roofs and façades life-span cycles are not always fully understood, poor maintenance often leads to material failure. Leaks arise typically as a result of poor maintenance, previous poor repairs or incorrect investigation methods.

    We provide a wide variety of specialist roof and façade leak detection solutions, utilising different non-intrusive and non-destructive leak testing methods such as electronic leak integrity testing, dry testing, dec scanning, moisture mapping, vacuum dewatering and thermographic surveys. With full MOD security clearance we can be trusted to access problems securely and quickly.


    Leak detection methods will be adapted to the materials type and leak location. No matter the material we have a solution to help you isolate, repair, and maintain your façade or roof for the future. We specialise in constructed buildings where materials have failed, corroded, shrunk, moved, or loosened during the weathering process and require detailed inspections. Modern, listed, tall, or difficult to access building, we can support you with a detailed leak investigations, roof corrosion treatment, repair, and ongoing roof maintenance plans.
