What are roof windows?
Roof windows, also known as skylights or rooflights, are windows that are incorporated into the design of a roof with the purpose of allowing natural light into the building. They are mostly outward opening, however, some roof windows are designed not to open, as the only purpose is to allow natural light to shine through the roof rather than natural air. Roof windows can be installed during the new build stage of a property or added later on.
Why should I install a roof window?
Roof windows can maximise the benefits of natural light to create a natural light source during the daytime. This is especially useful for areas that would otherwise be dark such as corridors and rooms that are not on the outer edge of a building and, as a result, are unable to make use of normal wall windows.
According to a study on the ‘Impact of Windows and Daylight Exposure on Overall Health and Sleep Quality of Office Workers’, workers in windowless environments experienced poorer scores in terms of subjective well-being and sleep quality. Workers with windows had more light exposure during the work week, which resulted in a trend toward more physical activity and longer sleep duration.
It’s fair to suggest that, as a result, the quality of work they could produce would benefit from their increased energy and concentration levels. This could also translate over to homes with more exposure to natural daylight. The occupants of the home would also benefit from better sleep and a healthier lifestyle.
Roof windows can provide additional ventilation for a building if it’s possible to open the window. Ventilation is important for any building as it can reduce the levels of airborne pollutants and moisture. It can help remove odours and just make the building feel more comfortable with fresh air coming in.
Triple glazed roof domes can provide a sound barrier to reduce the amount of noise you can hear from outside the building and the amount of noise that escapes the building. This is because of the additional thickness of the glass, which increases the mass of the window and more mass means less noise can get through it.
Triple glazed roof windows also make a building more energy efficient as it offers more insulation than single or double glazing. STORM Building Products’ Galaxy range includes single, double and triple skin roof domes.
Building restrictions can affect the type of windows that can be used to retain the style and look of the building or the area that the building is situated. In this scenario, sometimes it is possible to install a roof window instead of a regular window, which would be allowed even with building restrictions.

Roof windows aren’t just used for practical purposes, they also add a really stylish feature to a property and can increase its value.

Are roof windows a permitted development?
According to Planning Portal: “You do not normally need to apply for planning permission to re-roof your house or to insert roof lights or skylights as the permitted development rules allow for roof alterations subject to the following limits and conditions:
- Any alteration to project no more than 150 millimetres from the existing roof plane.
- No alteration to be higher than the highest part of the roof.
- Side facing windows to be obscure-glazed; any opening to be 1.7m above the floor.”
How many roof windows do I need? And what size roof window do I need?
As many as you want and however big you want! However, if you are looking to maximise the amount of natural light in a building without spending a huge amount, a good starting point would be making the total size (cm2) of your windows around 20% of the total size of the walls in the room.
