Can You Have a Skylight on a Flat Roof?

It is possible to install a skylight on a flat roof and you can trust it will look stunning. However, like with any building project, planning permission may be required, and this will depend heavily on your chosen product.

A low profile project means less input from your local planning authority and vice versa. If your rooflight complies with the legal building regulations, you’re all set to start your project. To help you make an informed decision, we’ve listed below three flat roof skylights that are unlikely to require planning permission.

What are the Different Types of Flat Roof Skylights?

Fixed Skylight


This is considered to be the most popular type of rooflight system across the UK. The main plus is that it is completely sealed, providing optimal thermal efficiency to help you save on bills. If you have an area that would benefit from floods of natural daylight, look no further than afixed flat skylight. It will help you create a pleasant environment and add a contemporary touch to your home.

Furthermore, you can choose between a standard fixed rooflight or a walk on should you need it to withstand the weight of foot traffic.

Ventilated Skylight

This type of rooflight system maximises daylight whilst creating a steady airflow for ventilation. It can be manually or automatically open by around 360mm to create an airy and light living space. Most frequently installed in kitchens and toilets, ventilated skylights remove excessive moisture and are an eco-friendly alternative to Air Conditioners.

Egress Skylight

For quick access to the roof, you’ll want to go for an egress rooflight system. As the name suggests, this type of skylight opens up to a 70 degree angle, serving as an egress window. This is especially useful for maintenance and inspection purposes without compromising on safety.
