How we approach dome rooflights in Dover
For Dover 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.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Typical uses for dome rooflights include schools, flats and commercial flat roofs.
Jobs in Dover are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
What you can choose
- Insulated PVC or GRP upstands
- Clear, opal or tinted
- Fall-through protection mesh
- Polycarbonate or acrylic
- Twin, triple or quad skin
- Smoke-vent versions available
- Light, impact-resistant domes
Things we check at survey
- Fire classification matters on some roofs
- Upstand condition decides whether you replace dome only or the whole unit
Building control and safety duties in Dover
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 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.
Read the planning permission guide before you commit to a design.

Dome rooflights in Dover: 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.
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 work alongside my builder in Dover?
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 Dover?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
