Why roof window work needs the whole opening checked
Window and roof assessed together
We look at the unit, the covering and the flashing so no part of the opening is ignored.
Pitch guides the installation
The roof angle affects the window and flashing arrangement needed for a sound fit.
Repairs don't stop at the frame
If the surrounding roof detail is failing, we'll identify that instead of blaming the window.
More daylight is great. A dry roof matters more.
A roof window can transform a dark roof space, but only if the installation keeps the roof envelope sound. We carry out new Velux window installation, repairs to existing roof windows and replacement of worn units in Alford. The window itself is only part of the job. The roof pitch, the surrounding tiles or slates, and the matching flashing arrangement all need to work together so water keeps moving away from the opening instead of finding the tiniest invitation indoors.


We separate window faults from roof faults
Not every leak around a roof window means the unit has failed. Sometimes the trouble sits in the flashing or the surrounding roof covering. We assess the window, the adjoining materials and the adjustments needed around the opening before we scope the work. That helps us decide whether the right answer is a repair, a full replacement, or attention to the roof detail around the window. It's a much better approach than changing the unit and leaving the real problem in place.
Frequently asked questions
Can you repair an existing Velux window?
Yes, depending on the fault. We assess the condition of the unit, the flashing and the surrounding roof covering before advising. Sometimes the window needs attention. Sometimes the leak or draught comes from the way the opening connects into the roof around it.
Why does the roof pitch matter for a roof window?
The pitch affects how water moves around the opening and which flashing arrangement suits the installation. A sound roof window isn't just dropped into the roof and hoped for. It needs to be matched to the slope and the covering that sits around it.
Do you replace worn roof windows as well as fit new ones?
Yes. We can assess worn or outdated roof windows for replacement where that makes more sense than repair. We also look at the surrounding roof detail at the same time, because a new unit still depends on the roof around it being properly adjusted and weatherproof.
