Why the state of school roofs can no longer be ignored

Across the UK, ageing school roofs are becoming a growing risk, not just to buildings, but to the quality of education delivered within them. What we are seeing is not a series of isolated issues, but a systemic problem driven by ageing infrastructure, underinvestment and increasing pressure on buildings that were never designed to last this long.

The scale of the issue is significant. According to the National Audit Office, around 38% of school buildings in England - approximately 24,000 - have exceeded their original design life.

That statistic alone tells a powerful story. Many of these buildings were constructed between the 1950s and 1990s, often using materials and methods that were never intended to last beyond 30 to 40 years. Today, they are still in daily use, decades beyond their expected lifespan. The consequences are now becoming increasingly visible. More than 700,000 pupils are currently learning in schools that require major refurbishment or replacement.

Roofs are a central part of this deterioration. As one of the most exposed elements of any building, they are often the first to fail and when they do, the effects are immediate and disruptive.

The financial scale of the problem is equally stark. The Department for Education has estimated that around £7 billion per year is needed to properly maintain and repair the school estate, yet actual funding has been closer to £3.1 billion annually. This gap has led to a growing backlog of maintenance, with roofing issues frequently deferred until they become urgent.

What happen when school roofs fail?

A leaking roof is far more than a simple maintenance issue, it quickly becomes an operational problem for schools. What may begin as a minor defect can lead to classrooms being taken out of use, lessons disrupted or relocated and valuable equipment and teaching materials damaged. Over time, the presence of moisture also

increases the risk of damp and mould, creating an environment that is neither healthy nor conducive to learning.

Early intervention is critical, because leaking roofs remain one of the most common and disruptive issues affecting school buildings. Even relatively small problems, such as blocked gutters, damaged membranes or failing flashings, can escalate rapidly into internal water ingress if left unaddressed. Once water begins to penetrate the building, the impact spreads quickly, affecting not just the structure, but everything within it.

Ceilings become stained and weakened. Electrical systems can be compromised. Over time, damp conditions create an unhealthy environment for both staff and pupils. In the worst cases, areas of schools may need to be closed entirely.

There is also a wider human impact. The National Audit Office has further highlighted that poorly maintained school environments can negatively affect pupil engagement, attendance and teacher morale. Put simply, the condition of the building directly influences the quality of education.

The structural risk

The recent RAAC crisis has brought national attention to the risks associated with ageing school buildings, particularly roof structures. In some cases, the consequences have been dramatic. Several schools experienced sudden roof collapses linked to RAAC, prompting urgent closures and emergency works. Critically, experts have noted that water ingress significantly increases the risk of failure in these materials. This highlights an important point that roof condition is not just about keeping water out - it is directly linked to structural safety.

According to a recent article in Schools Week, other ageing materials used in school construction are showing similar vulnerabilities. Surveys have found that alternative systems, such as woodwool or “stramit”, can deteriorate rapidly when exposed to moisture, with some experts warning of potential collapse risks. In many cases, the roof is the first line of defence. When it fails, it accelerates the deterioration of everything beneath it.

However, delaying roof maintenance is often seen as a way to manage budgets in the short term. In reality, it tends to do the opposite. Small issues become large ones. Localised repairs turn into full replacements. Emergency works replace planned maintenance.

What are the options for schools?

Proteus Waterproofing is already working with schools across the UK to tackle these challenges, supporting headteachers and local authorities in understanding the true condition of their roofs and the most effective way forward. Through a free roof survey service, Proteus identifies early signs of failure, assesses risk and provides clear,

practical guidance on the most cost-effective solutions - often extending the life of existing roofs through targeted refurbishment rather than costly replacement.

Working across the education sector, Proteus focuses on early assessment, practical repair and long-term performance - identifying issues before they become critical, delivering refurbishment solutions that minimise disruption and where necessary, installing high-performance waterproofing systems designed for durability and efficiency. Crucially, this is done in close collaboration with schools and their estates teams, ensuring solutions are both technically robust and practical within a live learning environment.

This approach recognises a simple but important reality that schools are far more than buildings - they are environments where young people learn and develop. When a roof fails, it is not just a maintenance issue - it disrupts education, places pressure on staff and impacts pupils directly.

With the UK school estate continuing to age, these challenges will only become more urgent. Roofing sits at the centre of the issue and waiting for failure is no longer an option. Proactive management, early intervention and the right technical support are essential - because the condition of the roof is not just about the building, but everything that happens beneath it.
