A flat roof in itself isn’t a bad thing but it does present more possible problems when it’s about carpet water damage compared to other roofing types. The prime risk here is that water can accumulate on top of the roof over time. Obviously flat roofs are made to prevent this & for that reason boast a slight slope to attempt & redirect the stream of water. Nonetheless though, if your flat roof has been around for a long time then it may have started to become bowl-shaped. Furthermore, if ice should form in your roof or it should collect plenty of wreckage in the form of leaves and branches, then this may form a type of ‘dam’ and then stop the waters from streaming naturally off the roof into the gutters.
