Flat roofs have a reputation for being problematic and prone to leaks. However the common problems with leaky flat roofs are usually as a result of one of these things:
In essence - a well designed, maintained and waterproofed flat roof shouldn’t be causing you problems or leak unless it’s old and needs replacing.
Is a flat roof really actually flat? Interestingly, no, they aren’t. Flat roofs actually have a very slight slope to allow rainwater to drain off the roof, but they do appear to be flat.
Why are flat roofs so popular? Really the truth is it all comes down to cost and energy efficiency. Flat roofs are very economical to construct. They also reduce the volume of the building thereby reducing energy and heating costs. They can also allow for the roof to be used for other activities like a patio or simply as a green roof.
How long are waterproofing membranes supposed to last for? Membranes used to cover and waterproof flat roofs usually last around 20 to 30 years. This is less than a traditionally built tiled roof. Building owners should plan to replace the membrane on their flat roof every 20 years or so.
What should I do to look after my flat roof? It’s a good idea to check over your flat roof every now and again to make sure the rainwater outlets aren’t blocked with debris or old leaves. Flat roofs are a lot less forgiving than steeply sloped ones so make sure you keep an eye to prevent any problems developing. Leaf guards can only cope with a small build up of leaves, so whilst it’s worth installing them, you can’t rely on them not becoming overwhelmed by the large amount of leaves blowing around in autumn.
