Dome rooflights in Brighton: what is involved?
We handle dome rooflights across East Sussex, including Brighton. 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.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Dome rooflights suit schools, flats and commercial flat roofs.
Brighton is the main town we list in East Sussex; we also cover nearby Hove and Portslade.
What you can choose
- Fixed or hinged with vent
- Clear, opal or tinted
- Insulated PVC or GRP upstands
- Twin, triple or quad skin
- Fall-through protection mesh
- Quick replacement on existing upstands
- Light, impact-resistant domes
Things we check at survey
- Old domes may be fragile — treat as fragile until checked
- Plastic domes have a lower acoustic and thermal performance than glass
Regulations for dome rooflights in Brighton
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 buildings other than dwellings, Approved Document L Volume 2 sets limiting U-values of 2.2 W/m²K for rooflights and 3.0 W/m²K for roof ventilators, including smoke vents. Fire classification of rooflight materials near boundaries is checked at specification.
See our building regulations guide for U-values, glazing limits and self-certification.

Dome rooflights in Brighton: questions
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on it.
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 work alongside my builder in Brighton?
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 Brighton?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
