Flat roofs have grown tremendously in popularity throughout the UK, and we’re still catching up with other countries where they are more common place. The development of flat roofs has been plagued by a number of different issues, such as how flat roof systems aren’t supported in the same way as gable and pitched roofs.
It is often times impossible to simply replace a pitched roof or other type of roofing system with a flat roof, because buildings need to be built in such a way as to be able to support a flat roof. In order to convert a building to a flat roofed building you’d need to either reconstruct the walls to be able to bare more stress or you’d need to add support columns underneath the roof to spread the burden further.
