Dome rooflights in Brentwood: what is involved?
For Brentwood 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.
In the East of England, bungalows and chalet bungalows with large flat-roofed extensions are common, and they often suit a long run of rooflights. In Brentwood, as anywhere, dome rooflights are the usual choice for older flat roofs with yellowed or leaking domes.
Jobs in Brentwood 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.
Specification options
- Polycarbonate or acrylic
- Twin, triple or quad skin
- Clear, opal or tinted
- Insulated PVC or GRP upstands
- Fall-through protection mesh
- Fixed, hinged or vented options
- Smoke-vent versions available
Things we check at survey
- Upstand condition decides whether you replace dome only or the whole unit
- Plastic domes have a lower acoustic and thermal performance than glass
Regulations for dome rooflights in Brentwood
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. Fire classification of rooflight materials near boundaries is checked at specification.
Read the planning permission guide before you commit to a design.

Questions about dome rooflights in Brentwood
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.
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on it.
Can you work alongside my builder in Brentwood?
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 Brentwood?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
