How we approach dome rooflights in Orpington
For Orpington 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.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Dome rooflights suit schools, flats and commercial flat roofs.
Orpington is around 21 km from central London, and we survey and fit throughout that part of Greater London, including the BR6 district.
What you can choose
- Insulated PVC or GRP upstands
- Polycarbonate or acrylic
- Twin, triple or quad skin
- Clear, opal or tinted
- Fall-through protection mesh
- Smoke-vent versions available
- Suits schools, flats and commercial roofs
What to check first
- Plastic domes have a lower acoustic and thermal performance than glass
- Upstand condition decides whether you replace dome only or the whole unit
Building control and safety duties in Orpington
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. Fragile-roof safety and access are planned before work starts.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
Can domes open?
Hinged and vented domes are available, manual or electric.
Do you fit dome rooflights in Orpington?
Yes. We survey and fit dome rooflights in Orpington and across Greater London. Send your postcode and we will offer a survey date when we reply.
Do I need to be at home for the survey in Orpington?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
