Dome rooflights for Brecon: the essentials
We handle dome rooflights across Powys, including Brecon. 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.
Slate roofs, stone cottages and terraced valleys are typical across Wales, and slim rooflights that sit low in the slates suit them best. Dome rooflights suit schools, flats and commercial flat roofs.
Neighbouring towns include Merthyr Tydfil (22 km) and Ebbw Vale (23 km). We offer a survey date when we reply to your enquiry.
Specification options

Things we check at survey
- Old domes may be fragile — treat as fragile until checked
- Upstand condition decides whether you replace dome only or the whole unit
Regulations for dome rooflights in Brecon
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. Fragile-roof safety and access are planned before work starts.
Read the planning permission guide before you commit to a design.

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 you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Should I replace a dome or switch to glass?
A dome is cheaper and quick; glass gives a clear view and better performance. On a tight budget, or a commercial roof with many units, domes remain sensible.
Do I need to be at home for the survey in Brecon?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Brecon?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
