Roof windowRoof windowclose

If you would like to install a roof light or roof window, then Building Regulations are likely to apply for the following reasons:

  • to install a roof light the roof structure will generally need to be altered to create the opening

  • the roof will have to be able to carry the load (weight) of the new roof light, if the roof cannot do this, then it will need to be strengthened

  • any window that is installed will need to prove that it has sufficient insulation against heat loss (i.e. it is energy efficient).

Where a roof light is replaced, Building Regulations approval will be required.
