The shape of the roof window you choose should fit in with the overall design of your home. Also, think about the amount of light that you want to let into your space. Some kinds of skylights may provide more natural light than others.
Determine the type of skylight you need

The pyramid-shaped roof windows can also be an ideal choice if you want to give a more modern look to your property. Round-shaped roof windows might be suitable for larger spaces that need more natural light. Tubular skylights, on the other hand, can fit well into small areas such as hallways or closets.
The shape of your replacement skylight should be selected based on the specific needs of your property as well as your personal preferences.

If you want to avoid heat loss and improve your home's energy efficiency, you must choose a high-quality material and type of glass. You should also look for a skylight with a high insulation value. Choosing double-glazed windows, for example, will help provide adequate insulation and result in lower energy costs due to the barrier of the three layers of glass and gas.
