How we approach dome rooflights in Richmond
We handle dome rooflights across Greater London, including Richmond. 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.
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. Typical uses for dome rooflights include older flat roofs with yellowed or leaking domes.
Richmond sits about 2 km from Twickenham and 3 km from Isleworth, and we cover the whole TW9 postcode district and the roads in between.
What you can choose
- Twin, triple or quad skin
- Polycarbonate or acrylic
- Clear, opal or tinted
- Fall-through protection mesh
- Fixed or hinged with vent
- Low cost per unit
- Smoke-vent versions available
Things we check at survey
- Fire classification matters on some roofs
- Plastic domes have a lower acoustic and thermal performance than glass
Building control and safety duties in Richmond
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. 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.

Questions about dome rooflights in Richmond
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.
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
Can domes open?
Hinged and vented domes are available, manual or electric.
Do I need to be at home for the survey in Richmond?
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 Richmond?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
