How we approach dome rooflights in Gorseinon
For Gorseinon homes and buildings we offer dome rooflights: polycarbonate and acrylic domes for flat roofs, new or replacement. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. Typical uses for dome rooflights include older flat roofs with yellowed or leaking domes.
Gorseinon is around 9 km from Swansea, and we survey and fit throughout that part of West Glamorgan, including the SA4 district.
Specification options
- Twin, triple or quad skin
- Insulated PVC or GRP upstands
- Clear, opal or tinted
- Fixed or hinged with vent
- Polycarbonate or acrylic
- Quick replacement on existing upstands
- Light, impact-resistant domes
Before you order: points to check
- Fire classification matters on some roofs
- Old domes may be fragile — treat as fragile until checked
Rules and responsibilities in Gorseinon
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. 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 Gorseinon
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.
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.
