Often the problem is linked to the roof covering; it may be old with dried-out patches that crack or bubble and allow water ingress in these areas. Sometimes these problems can be easily overcome with minor roof repairs, but if left too long can result in the necessity of a complete roof cover replacement. In extreme circumstances the roof structure can become damaged and this leads to the harsh reality of a complete roof replacement.
Currently, UK regulations specify insulation layers within the roof space. Fitted correctly, insulation can prevent condensation, which leads to premature wood-rot in the structure of the flat roof.
One of the most common misconceptions concerned with flat roofing is that it is not consistently flat. An incorrectly placed roof can lead to pooling and water ingress in delicate areas, such as joins in felt or membrane covering. A slight gradient of roughly 1 in 80 should be adhered to to allow adequate run off.
Regular visual inspections of your flat roof, even just once or twice a year, particularly after rainfall can alert you to potential problems at the earliest outset, giving you a much better chance of correcting issues before they grow into big headaches.
