What do skylight repairs & leak fixes in Cowbridge involve?
Thinking about skylight repairs & leak fixes in Cowbridge? The short answer: leak tracing, resealing, actuator repairs and glass replacement. The longer answer depends on your roof, which is why we survey before we price.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. In Cowbridge, as anywhere, skylight repairs & leak fixes are the usual choice for leaks, condensation, misted units and failed actuators.
We work across South Glamorgan, including Cowbridge, and in neighbouring towns such as Llantwit Major and Bridgend. Access, parking and how the glass reaches the roof are all checked at the survey.

Do you need permission in Cowbridge?
Welsh householder permitted development (Class C) allows rooflights that project no more than 15 cm and sit no higher than the existing roof — but not in conservation areas, National Parks, AONBs or World Heritage Sites. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
Approved Document L in Wales (2022 edition) sets 2.2 W/m²K for rooflights, measured horizontally, and 1.4 W/m²K or Band B for roof windows in existing homes. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Is it condensation or a leak?
Condensation forms on the inside face on cold days and comes back in the same pattern. A leak appears when it rains and often tracks down the reveal.
Can you fix a misted rooflight?
A misted unit means the glass seal has failed. The sealed unit, or the whole rooflight, needs replacing.
Do you repair roof windows too?
Yes — flashings, seals, hinges and glass on pitched roof windows.
