Flat roofs in large buildings are often prone to leaks, presenting a significant challenge for property owners and facility managers. As an independent test house, Thornton Consulting offers a highly professional and specialised flat roof leak detection and consultancy service for clients throughout the UK and Ireland. The test method applied will be dependent on the initial survey and determined by the membrane material or roof system. For example, although electronic testing has become a valuable aid in accurately locating the source of water ingress, not all waterproofing systems are compatible and alternative methods can also be implemented. This bespoke service provides a considerable benefit for both newly installed and aged roofs, ensuring the integrity of commercial and industrial buildings, hospitals, municipal car parks and residential apartment blocks.
Several factors contribute to a flat roof’s vulnerability, making it more susceptible to water infiltration than their sloped counterparts. One key factor is the lack of natural water drainage on the roof area. Unlike pitched roofs that naturally guide rainwater away, flat roofs rely on artificial drainage systems such as gutters and drains. These systems require careful maintenance to remain effective, and any neglect or blockage can lead to ponding – the accumulation of water on the roof surface. Prolonged ponding exposes the roof to increased pressure and the risk of water seepage through seams and joints.
Another contributing issue responsible for leaks in these flat areas is the materials used in their construction. Flat roofs commonly employ materials like asphalt or rubber membranes, which are prone to wear and tear over time. Exposure to the elements, temperature fluctuations, and UV radiation can cause these materials to degrade, leading to cracks, splits, or membrane shrinkage. Such deterioration compromises the roof's stability, allowing water to penetrate and damage the building structure and interior contents.
Furthermore, the expansion and contraction of building materials due to temperature variations play a role in their susceptibility to water ingress. This constant movement can create stress on seams, flashings, and other vulnerable points, ultimately resulting in gaps where water can infiltrate.
Regular inspections, pro-active maintenance, and the use of high-quality roofing materials correctly installed, can mitigate these risks and prolong the lifespan of flat roofs, ensuring their functionality and preventing costly water damage.
