A roof window is the quickest way to bring daylight into a loft, landing or vaulted room, and usually doesn't need planning permission. We fit genuine Velux and equivalent roof windows with the correct flashing kits, so they stay watertight for decades.
We also replace old, drafty or leaking roof windows like for like, often from inside without scaffolding, and repair flashings that have started to let water in.

Do I need planning permission for a roof window?
Usually not, as long as it doesn't stick out more than 150mm and isn't on a roof facing the road in a conservation area. Listed buildings always need consent.
Can you replace a Velux from inside?
In most cases, yes. Like-for-like replacements are often done from inside the room without scaffolding.
Why is my roof window leaking?
Usually a failed or poorly fitted flashing kit, slipped tiles around the frame, or a perished seal. We'll show you which with photos.
