Dome rooflights for Bow: the essentials
Thinking about dome rooflights in Bow? The short answer: polycarbonate and acrylic domes for flat roofs, new or replacement. The longer answer depends on your roof, which is why we survey before we price.
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. Think of dome rooflights for older flat roofs with yellowed or leaking domes.
Bow is around 8 km from central London, and we survey and fit throughout that part of Greater London, including the E3 district.
What you can choose
- Insulated PVC or GRP upstands
- Twin, triple or quad skin
- Clear, opal or tinted
- Fall-through protection mesh
- Polycarbonate or acrylic
- Light, impact-resistant domes
- Smoke-vent versions available
Things we check at survey
- Old domes may be fragile — treat as fragile until checked
- Fire classification matters on some roofs
Rules and responsibilities in Bow
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. Fragile-roof safety and access are planned before work starts.
Read the planning permission guide before you commit to a design.

Common questions
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes 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 Bow?
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 Bow?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
