What do dome rooflights in Bexleyheath involve?
We handle dome rooflights across Greater London, including Bexleyheath. 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.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Think of dome rooflights for older flat roofs with yellowed or leaking domes.
Jobs in Bexleyheath 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
- Clear, opal or tinted
- Twin, triple or quad skin
- Polycarbonate or acrylic
- Insulated PVC or GRP upstands
- Light, impact-resistant domes
- Low cost per unit
Before you order: points to check
- Fire classification matters on some roofs
- Plastic domes have a lower acoustic and thermal performance than glass
Rules and responsibilities in Bexleyheath
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. 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.

Questions about dome rooflights in Bexleyheath
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes 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.
Can domes open?
Hinged and vented domes are available, manual or electric.
Can you work alongside my builder in Bexleyheath?
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 Bexleyheath?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
