FAQ
Why should I choose a roof window over a traditional dormer?
Roof windows are generally more cost-effective and faster to install than dormer extensions. Because they follow the natural pitch of your roof, they don’t usually require structural changes to your roofline. They also provide significantly more natural light—up to twice as much as a vertical window of the same size—and offer superior ventilation by allowing hot air to escape through the highest point of the room.
What is the difference between Center-Pivot and Top-Hung windows?
Center-pivot windows are the most common; they rotate 180 degrees, making them incredibly easy to clean from the inside. They are ideal when the window is placed at a lower height. Top-hung windows open outward from the top, providing an unobstructed view and a feeling of extra space—these are perfect if your window is installed at eye level or above a desk or seating area.
Do I need planning permission to add a roof window?
In most cases, installing roof windows falls under Permitted Development, meaning you don’t need formal planning permission as long as the windows don’t protrude more than 150mm from the roof plane. However, if you live in a listed building or a conservation area, you will likely need approval. We always recommend checking with your local authority, and we can help ensure your installation meets all necessary building regulations for thermal performance.
How do I know if my old roof window needs replacing?
The most common sign of failure is condensation between the glass panes, which means the vacuum seal has broken and the window is no longer insulating your home. You should also look for water staining on the internal timber frame or draughts coming from the edges. Modern replacement windows are significantly more energy-efficient than those made 20 years ago, often fitting into the same structural opening with minimal mess.
Are roof windows noisy when it rains?
Many homeowners worry about the “drumming” sound of rain on the glass. Modern roof windows come with laminated safety glass and toughened outer panes that significantly dampen exterior noise. If you are particularly sensitive to sound, we can install specialized “acoustic glazing” designed specifically to reduce rain noise by up to 50% compared to standard double glazing.
How do I prevent my room from getting too hot in the summer?
Because roof windows face the sky, they can catch a lot of direct sunlight. To prevent the “greenhouse effect,” we recommend installing anti-heat blackout blinds or external heat-protection awnings. These can block up to 70% of solar heat before it even hits the glass, keeping your room cool in July without sacrificing the view. Many modern units can even be fitted with solar-powered motors to open and close automatically based on the temperature.
