What do dome rooflights in Greenwich involve?
Dome rooflights in Greenwich means polycarbonate and acrylic domes for flat roofs, new or replacement. We cover the SE10 district and the rest of Greater London, with a survey before any price is fixed.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. Dome rooflights suit older flat roofs with yellowed or leaking domes.
Greenwich sits about 2 km from Blackheath and 3 km from Lewisham, and we cover the whole SE10 postcode district and the roads in between.
Options we can specify in Greenwich
- Twin, triple or quad skin
- Polycarbonate or acrylic
- Fixed or hinged with vent
- Fall-through protection mesh

What to check first
- Fire classification matters on some roofs
- Old domes may be fragile — treat as fragile until checked
Rules and responsibilities in Greenwich
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. 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. Fragile-roof safety and access are planned before work starts.
Our planning guide covers each nation in more detail.

Questions about dome rooflights in Greenwich
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
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.
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
Do I need to be at home for the survey in Greenwich?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Greenwich?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
