The question of pitched roof windows vs flat roof windows really boils down to what you can physically have in your property. For example, if you already have a flat roof, you won’t physically be able to put pitched roof windows in!
So if you are at the initial planning stages of a house extension, a loft conversion or any other kind of building works such as an outbuilding that you need to choose a roof for, you are better off knowing the pros and cons of pitched vs flat roof windows before you decide on what roof to have put in.

Flat roof windows
If you have a flat roof, you will need to have a different type of window to a pitched roof. It only needs to be able to suit an incline of 0 – 15 degrees which is vastly different from that of a pitched roof.
You will have various options available for your flat roof, such as:
Flat glass roof lights: These are one of the more popular choices as they are many different standard sizes and finishes to choose from. They are also designed to prevent water from pooling which is one of the major issues with a flat roof and can cause damage.
Walkable roof lights: If you require access to your roof then you might need to have reinforced windows in the roof. That way you’ll get all the benefits of the roof window plus access to the room below.
Glass-domed roof lights: a combination of glass and polycarbonate creates a strong exterior that will allow rainwater to run off and limits the build-up of condensation. Full polycarbonate domes are almost unbreakable, which is perfect if you are concerned about security.
Pitched roof windows
A pitched roof is likely to have an incline between 15 and 90 degrees, so you will need a specific type of window to suit it.
Room type: The type of pitched roof window you choose will depend on the room beneath the roof. If, for example, the window is in a bathroom, privacy will be one of the considerations. You can opt for obscured glass to ensure your modesty is preserved and you can select options that handle condensation better than others which will maintain the life of your window on such a humid roof. Also, if you are inserting the roof window in a room where there is a stunning view, you can choose a top hung window that won’t restrict your view.
Shatterproof: Laminated windows are an option in pitched roofs too, and this provides additional security from shattering. If they are struck, they will not shower glass shards down into the room beneath.
Frame options: There are several available which will suit different house styles. The key ones you can choose as standard is –
- uPVC comes with a lot of low maintenance benefits that should be extremely durable
- White polyurethane (PU) windows are similar to uPVC options but also have a timber core. These are increasingly popular and are low maintenance once installed too
- Pine frames offer a more traditional look and give a classic finish
In terms of which is better, pitched roof windows have many different options and can provide ventilation, sound insulation, and beautiful vistas too. But of course, if you have a flat roof already, you’ll need to select an option right for that!
