Back in 2011, the Daily Telegraph ran a feature in their property section about the problem of flat roofs. They looked at some of the most common issues and tried to offer advice towards preventing damage to flat roofs in the future.
Although this article was written over two years ago, the same problems still remain across new flat roofs and older flat roofs, especially in the Yorkshire region. Many flat roofs are built too flat which leads to the materials sagging in the middle and inadequate support structures put in place. This then means that rain water pools as it does not run off the roof and after a period of time will permeate through any imperfections or gaps in the material.
A common misconception is that flat roofs should be flat. Flat roofs should actually be slightly raised in the middle to allow for water to run off. If there is no raised middle section, then it doesn’t matter how good the material used is; there will eventually be a leak.
A lack of maintenance can also be an issue on flat roofs in the Yorkshire area, with a harsh climate, especially in the North Yorkshire Moors, causing problems. Sun blistering and damage caused by wind are two of the more common problems, but there are many other reasons why your flat roof could be faulty.
Here at DPR, we have been repairing flat roofs in the area for a number of years, and are still amazed with the amount of flat roofs, especially new ones which do not have the correct infrastructure in place. Our team of roofers can repair leaks linked to many different causes but would always advice that a raised section and structural support is put in should it now already be there and you if you are experiencing a leak. This will add longevity to your roof and should prevent the constant pooling that you have already seen.
So although The Telegraph told us to look out for our flat roofs, it would appear that little has been done to correct the problems. Should you notice any problem with your flat roof, please do not hesitate to call DPR on the number at the top of the page.
