What do dome rooflights in Belfast involve?
Thinking about dome rooflights in Belfast? 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.
Many Northern Irish homes have later flat-roofed kitchen extensions where an old dome can be swapped for glass. Typical uses for dome rooflights include schools, flats and commercial flat roofs.
Belfast is the main town we list in County Antrim; we also cover nearby Castlereagh and Newtownabbey.
Specification options
- Insulated PVC or GRP upstands
- Fixed or hinged with vent
- Twin, triple or quad skin
- Polycarbonate or acrylic
- Clear, opal or tinted
- Smoke-vent versions available
- Suits schools, flats and commercial roofs
Things we check at survey
- Upstand condition decides whether you replace dome only or the whole unit
- Plastic domes have a lower acoustic and thermal performance than glass
Building control and safety duties in Belfast
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 Northern Ireland, Technical Booklet F2 covers energy performance; we supply the manufacturer's data for building control. Fragile-roof safety and access are planned before work starts.
Read the planning permission guide before you commit to a design.

Dome rooflights in Belfast: questions
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Can domes open?
Hinged and vented domes are available, manual or electric.
Can you work alongside my builder in Belfast?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Belfast?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
