Understanding Roof Windows


Reading time: 6 minutes

Finding ways of brightening up a room and changing the character of a home can take many different forms, from redecorating to bigger projects like converting a loft or building an extension. One way of changing parts of the home is the introduction of roof windows.


Are roof windows a good idea?

Installing roof windows will add more natural light giving a particular room a whole new lease of life. A dark room with no windows, or even only one window, can still feel unwelcoming even with electric light. Bringing in natural light can make a room more of a working space, or a place to enjoy hobbies. Adding a more liveable space to a home is incredibly practical and may even improve a property’s value.


Are roof windows good for saving money?

By adding more natural light to a room, this can greatly reduce the need to use artificial light. This in itself is a money-saving benefit, even reducing energy bills a little can make a big difference in the long run. Also, a properly installed roof light is designed to be well insulated, so shouldn’t lead to further heat loss in the home. 


Planning a roof window

There are still a few things to take into consideration when installing roof windows:

  • Planning Permission
  • Hole in the Roof
  • Placement
  • U-value
  • Taking Up Space

What’s the difference between a roof window and a skylight?

While the terms ‘roof window’ and ‘skylight’ (sometimes known as a rooflight) are used interchangeably, and referred to as the same thing, there is a difference. Roof windows are set at the same plane as the roof it’s installed on, which means if the angle of the roof is at 45 degrees, the roof window will be too. The roof must also be at a pitch of at least 15 degrees to qualify as a roof window. A skylight can be fitted to let light into flat roofs and designed to be horizontal or at an orientation of under 15 degrees.


What type of roof window should I get?

To find the right kind of roof window, or skylight, we can split this into various types that are available. Each has their own pros and cons that are dependent on your needs.

  • Top Hung Roof Windows
  • Centre Pivot Roof Windows
  • Opening or Fixed Skylights
  • Roof Lanterns
  • Walk On Skylights
  • Roof Domes
  • Sun Tunnels
