Replacing a flat roof might be an unnecessary expense if you are able to fix it instead. You might be able to save yourself precious time and money, by making do with what you have and just carrying out some repair work instead. Whilst flat roofs will definitely need to be replaced fairly regularly, there is no point replacing them sooner than needed and reducing their lifespan.
So what are the alternatives? There are now some very good paint-like solutions, that can be painted directly onto the roof. This will patch it up if it is damaged, and will make it fully waterproof again. It is very easy to apply, so it shouldn’t cost too much for a roofing contractor to do it for you. It will help to prevent leaking and will fill in any holes that might have developed, so if you do notice a leak, call a roofing contractor straight away.
