When you buy roof lights, it is possible to install them yourself rather than paying a professional to do this for you. This can help to save you some money on the cost of buying roof lights as it will probably not be cheap to hire someone who knows their way around fitting a roof light.
If you do decide to fit your roof light or skylight yourself, you should have previous experience in construction and, specifically, roofs. Just bear in mind that the work will not be guaranteed if you do it yourself, so if you have any problems in future, you will have to fix them yourself or pay somebody to come out and look at them.
If you don’t have prior experience, you will need to hire someone to fit your roof light for you. It is a complicated process and if something goes wrong, you could end up with problems like leaks and poor insulation.
