Dome rooflights for Swansea: the essentials
Our dome rooflights service in Swansea covers polycarbonate and acrylic domes for flat roofs, new or replacement. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. Typical uses for dome rooflights include older flat roofs with yellowed or leaking domes.
We cover all of Swansea and the SA1 district, and nearby Briton Ferry and Gorseinon.
Choices for your Swansea project
- Twin, triple or quad skin
- Fixed or hinged with vent
- Clear, opal or tinted
- Insulated PVC or GRP upstands
- Fall-through protection mesh
- Smoke-vent versions available
- Suits schools, flats and commercial roofs
What to check first
- Upstand condition decides whether you replace dome only or the whole unit
- Plastic domes have a lower acoustic and thermal performance than glass
Regulations for dome rooflights in Swansea
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. 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 Swansea?
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 Swansea?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
