What do flat rooflights in Cwmbran involve?
We handle flat rooflights across Gwent, including Cwmbran. In short: fixed double or triple glazed rooflights for flat roofs and extensions. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. Flat rooflights suit landings, bathrooms and rear extensions with flat roofs.
Neighbouring towns include Pontypool (5 km) and Risca (7 km). We offer a survey date when we reply to your enquiry.
Options we can specify in Cwmbran

What to check first
- Rooflights count toward glazing in an extension, which matters for Building Regulations energy and overheating rules
- The roof membrane must be dressed up the upstand before the unit goes on
Consents for flat rooflights in Cwmbran
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.
Welsh Building Regulations expect new or replacement rooflights to reach 2.2 W/m²K and roof windows 1.4 W/m²K or a Band B rating. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.

Questions about flat rooflights in Cwmbran
Do flat rooflights leak?
A well-fitted flat rooflight should not leak. Leaks almost always come from the upstand or membrane detailing, not the glass unit, which is why the upstand height and the way the roof covering is dressed up and under the frame matter more than the brand.
How long does it take?
Fitting into a prepared upstand usually takes a day. Forming a new opening in an existing roof, including making good inside, is often two to three days.
Can you fit into my existing flat roof?
Yes. We form a new opening, trim the joists, build and waterproof an upstand and make good the ceiling. A survey confirms the joist direction and roof build-up first.
Is the survey in Cwmbran free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
