How we approach dome rooflights in Aberdare
We handle dome rooflights across Mid Glamorgan, including Aberdare. In short: polycarbonate and acrylic domes for flat roofs, new or replacement. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Dome rooflights suit schools, flats and commercial flat roofs.
Aberdare sits about 6 km from Rhondda and 6 km from Merthyr Tydfil, and we cover the whole CF44 postcode district and the roads in between.
Options we can specify in Aberdare
- Fall-through protection mesh
- Twin, triple or quad skin

Before you order: points to check
- Plastic domes have a lower acoustic and thermal performance than glass
- Old domes may be fragile — treat as fragile until checked
Building control and safety duties in Aberdare
For non-domestic buildings, planning depends on the building and its location; building regulations cover thermal performance and the fire classification of rooflights near boundaries. 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. Fragile-roof safety and access are planned before work starts.
Read the planning permission guide before you commit to a design.

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