How we approach dome rooflights in Cwmbran
Our dome rooflights service in Cwmbran covers polycarbonate and acrylic domes for flat roofs, new or replacement. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Think of dome rooflights for older flat roofs with yellowed or leaking domes.
Cwmbran sits about 5 km from Pontypool and 7 km from Risca, and we cover the whole NP44 postcode district and the roads in between.
Specification options

What to check first
- Fire classification matters on some roofs

Regulations for dome rooflights in Cwmbran
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. We confirm the route for your building before ordering.
For non-domestic buildings in Wales, Approved Document L sets limiting U-values for rooflights and roof ventilators; we supply the manufacturer's data for the building control submission. Fire classification of rooflight materials near boundaries is checked at specification.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on it.
Do you fit dome rooflights in Cwmbran?
Yes. We survey and fit dome rooflights in Cwmbran and across Gwent. Send your postcode and we will offer a survey date when we reply.
Can you work alongside my builder in Cwmbran?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
