Dome rooflights in West Glamorgan: the essentials
Across West Glamorgan, our dome rooflights work covers polycarbonate and acrylic domes for flat roofs, new or replacement. Survey first, fixed price second, fitting third.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. Slate roofs, stone cottages and terraced valleys are typical across Wales, and slim rooflights that sit low in the slates suit them best.

Planning and building rules in Wales
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.

How the job runs
- Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
- Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common questions
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 domes open?
Hinged and vented domes are available, manual or electric.
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
Do I need to be at home for the survey in West Glamorgan?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
