The rooflight market is enormous and it isn’t enough to simply know that you want a rooflight. You need to know the kind that you want, the style, and the specifications if you are going to order it for yourself. This means choosing a rooflight that will suit your home and will fit in with what you already have.
If you have never bought a rooflight before, it is best to be led by the installer. Find someone who is a builder and can recommend types of rooflights to you. They will be able to show you different styles, so you can then look them up and choose the look that is going to be right for you. A flat glass rooflight will look very different to a domed polycarbonate rooflights, for example, so you need to understand the aesthetic differences. An installer can also advise you on the right sizes, so you can choose the right one.
