Dome rooflights for Dulwich: the essentials
We handle dome rooflights across Greater London, including Dulwich. 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.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Dome rooflights suit older flat roofs with yellowed or leaking domes.
We work across Greater London, including Dulwich, and in neighbouring towns such as Brixton and Peckham. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Twin, triple or quad skin
- Clear, opal or tinted
- Fixed or hinged with vent
- Fall-through protection mesh
- Polycarbonate or acrylic
- Fixed, hinged or vented options
- Suits schools, flats and commercial roofs
Things we check at survey
- Old domes may be fragile — treat as fragile until checked
- Upstand condition decides whether you replace dome only or the whole unit
Regulations for dome rooflights in Dulwich
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Dome rooflights in Dulwich: 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.
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Do I need to be at home for the survey in Dulwich?
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 Dulwich?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
