I have a flat roof garage which simply collects the rainwater on top whenever it rains - even a small amount of rain takes days to evaporate. I cannot see any drainage point on the roof at all. Is there anything I can hve done to rectify this?
Sorry if I have not explained this in a very technical way - I am a woman who knows nothing about roof design!
