The Task
When water began leaking through a flat roof into one of the classrooms, the school contacted Thameside Roofing Ltd, a Langley Approved Contractor who then commissioned Langley to carry out a comprehensive survey to investigate the cause of the problem and to give a thorough report on the condition of all the school’s flat roofs.
The Outcome
The survey established that a synthetic membrane had been overlaid on four roofs a few years before in an attempt to cure the problem, but that this had failed. Langley identified that the main cause of the problem was a poor standard of workmanship and a defective cavity tray which allowed rain water to pour into the space under this membrane, on top of the original asphalt roof. The water was then finding its way through to the interior of the building, causing damage and disruption to classrooms.
