Roof windows, also called roof lights or skylights, are a popular way to get additional light into a home. They are relatively easy to install and come in a wide range of materials, styles and sizes to fit the needs of different homes and homeowners. The two main types of windows are pitched and flat roof windows. There is a lot more to choosing a roof light than picking one for your type of roof. We explore these nuances below.

Differences Between Flat and Pitched Roof Windows
The main difference between these two types of roof lights is their angles. Depending on the roof, a flat roof light is installed horizontally or at a very small angle. A pitched roof window is installed at an angle matching the roof’s pitch, typically 15-60 degrees.
Another difference is in their installation. The slanted glass on a pitched roof window means rainwater and debris slide off, making their installation easier. That said, some contractors will use flashing kits around pitched roof roof lights, especially when they are at a relatively low angle, to ensure water doesn’t seep in. Due to the potential for water and debris to enter beneath them, flat roof windows require a membrane that stops that from happening.
Both roof lights have changed in recent years, with some flat roof lights coming with electric switches that allow them to open. Conversely, some pitched roof lights cannot be opened, although most can.
Planning Permission
Installing a roof light does not require planning permission, as doing so is covered by the Permitted Development Scheme. You will not need it if you meet certain criteria, especially around roof extensions. Most flat skylights require that the roof be extended to accommodate them. You will need planning permission if the additional roof plan exceeds 1.5 metres.
Roof Lights for Loft Conversions
Pitched roof lights are the best option for a loft conversion. They can help you transform a log into a living space or home office. The best pitched roof windows for these conversions can be installed in about a day by an experienced contractor. When shopping for roof windows UK for a loft conversion, you have many options to choose from, making their selection much easier.
Using a pitched roof skylight during a loft conversation can also save you a lot of money compared to a “dormer” roof conversion, which takes more time and is more complicated.
Skylights Let More Light in
A similarity between a flat and pitched roof skylight is that they let in more light than traditional windows. This is because they are installed facing the sky. However, you need to think about placing them in optimal positions for them to provide you with the additional light you need.
Installing flat and pitched roof skylights is much easier than many think, and their benefits are immediately apparent. They both can let additional and light air into a room, making it airier and more welcoming. They are also installed differently due to the angle they are installed at.
