The duration of an RAAC survey varies based on the size and complexity of the building, as well as how accessible the roof or ceiling areas are. It can often be completed in a single visit for smaller properties, while larger or multi-block sites may need extra time to properly assess the entire structure.

We aim to use non-intrusive inspection methods wherever possible; however, if key structural elements are concealed, it may sometimes be necessary to perform small opening-up works or drilling to verify panel bearing or reinforcement. When this happens, we carry out only the minimum work required and ensure all health and safety protocols are followed.

Our assessment method involves inspecting for signs of water ingress (current or historic), checking bearing lengths, looking for cracking or deflection, and assessing structural safety. We use these indicators to provide a risk classification and advise on appropriate remedies; whenever possible, we integrate roofing-grade protective or waterproofing solutions as a first line of maintenance.

Commissioning a RAAC inspection usually involves individuals responsible for building safety, maintenance or strategic oversight, including facilities managers, estates teams, senior leaders or property managers, and we can advise on who should be involved during the initial consultation to ensure the process runs smoothly.

Most buildings can remain operational during surveys or roofing-led remediation works, as these processes are planned to minimise disruption, and where temporary closures, restricted access or safety measures are required we provide clear guidance and help arrange the safest approach around day-to-day activities.

Buildings constructed during the RAAC era frequently contain asbestos or other legacy materials. When these are encountered during an inspection, we follow the correct safety procedures, advise on the appropriate next steps and help coordinate any additional specialist investigations required before remediation can progress.

Assessment reports typically outline the confirmed presence and condition of RAAC, the associated level of risk, and the recommended options for managing or remediating affected areas, and where appropriate these options may include roofing-based protection measures, stabilisation plans or the early stages of removal preparation.

Liquid-applied roofing systems can be used to protect RAAC roof structures when the surface is stable enough to accept the application, as these systems form a seamless waterproof barrier that limits moisture ingress, supports structural stability and extends the usable life of affected roofs.

If the roof structure is assessed as too unstable for liquid-applied systems, the safest approach is to avoid surface works until the underlying panels have been secured. In these situations, temporary protection, stabilisation measures or controlled access arrangements are used while a more suitable remediation plan is developed.

Our services are designed to support schools, academies, NHS facilities, councils and commercial estates, and we understand the operational pressures of these environments, which is why our inspections and remediation work are carried out with careful consideration of safety, scheduling and disruption management.
