How Might Winter Have Damaged Flat Roofs?

Daniel Bracewell • 8 March 2023

If you have a flat roof, the onset of spring in a few weeks could be the ideal time to get it checked out for signs of winter damage.


While the most vital time for flat roof repair in Stockport is at the start of autumn so that any vulnerability is addressed before the wind, rain, snow and icy conditions all arrive, you may also find it valuable to do so in spring precisely because the same harsh weather may have taken its toll. 


Although most of the snow this winter has come in two spells, one in Mid-December and another a month later, it is still worth knowing what kind of damage snow can do


If snow levels are very heavy, the weight can cause bowing and ponding. This means the surface becomes slightly concave as the weight presses down on it, allowing water to accumulate when the snow melts.


Another snow and ice issue is freeze-thaw. This is not as dramatic as the effects of water when it gets into cracks in stone or tarmac (which causes potholes), but if water does seep into cracks, the ice, which expands as it gets near freezing point, will widen them. This can also lead to leaks occurring.


Ice can also be a specific problem as it can form dams that prevent melting water from freezing. It can also freeze up guttering. All this can make problems of freeze-thaw, ponding and leaks worse.


If you see signs of any of these problems, that is your cue to call in the experts. We can inspect your flat roof and establish if there are indeed problems of this sort.


Not only can we mend any damage done over the winter and see that the roof is ready for the spring and summer of 2023, but also fix it up in a way that ensures it is copes far better with next winter.
