Roof windows are a popular choice for self-builders and extenders, and rightly so: they allow masses of natural daylight into your home and can transform lofts and other dark interiors into light-filled havens.

But should you install a roof window yourself? Generally, roof window manufacturers advise employing a professional installer – expect to pay between £200 and £500 for installation, depending on the size of the roof window. Only tackle this task if you are a very skilled DIYer.
