Dome rooflights for Tottenham: the essentials
For Tottenham 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.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. In Tottenham, as anywhere, dome rooflights are the usual choice for older flat roofs with yellowed or leaking domes.
Jobs in Tottenham 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
- Fall-through protection mesh
- Polycarbonate or acrylic
- Clear, opal or tinted
- Fixed or hinged with vent
- Twin, triple or quad skin
- Fixed, hinged or vented options
- Quick replacement on existing upstands
Things we check at survey
- Upstand condition decides whether you replace dome only or the whole unit
- Fire classification matters on some roofs
Building control and safety duties in Tottenham
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.
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
Can you work alongside my builder in Tottenham?
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 Tottenham?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
