What do dome rooflights in Cowbridge involve?
Thinking about dome rooflights in Cowbridge? The short answer: polycarbonate and acrylic domes for flat roofs, new or replacement. The longer answer depends on your roof, which is why we survey before we price.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. Dome rooflights suit older flat roofs with yellowed or leaking domes.
We work across South Glamorgan, including Cowbridge, and in neighbouring towns such as Llantwit Major and Bridgend. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Fall-through protection mesh
- Insulated PVC or GRP upstands
- Fixed or hinged with vent
- Polycarbonate or acrylic
- Twin, triple or quad skin
- Fixed, hinged or vented options
- Light, impact-resistant domes
What to check first
- Fire classification matters on some roofs
- Upstand condition decides whether you replace dome only or the whole unit
Rules and responsibilities in Cowbridge
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. Product data for building control is supplied with every quote.
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.
Read the planning permission guide before you commit to a design.

Common questions
Can domes open?
Hinged and vented domes are available, manual or electric.
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.
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 I need to be at home for the survey in Cowbridge?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Cowbridge?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
