Dome rooflights in Bexley: what is involved?
Thinking about dome rooflights in Bexley? 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.
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. Think of dome rooflights for older flat roofs with yellowed or leaking domes.
From Bexley to Bexleyheath, Sidcup and Welling, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Bexley
- Clear, opal or tinted
- Polycarbonate or acrylic
- Fall-through protection mesh
- Fixed or hinged with vent
- Insulated PVC or GRP upstands
- 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
Regulations for dome rooflights in Bexley
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.

Dome rooflights in Bexley: questions
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on it.
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.
