Dome rooflights in Witham: what is involved?
For Witham 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. Typical uses for dome rooflights include schools, flats and commercial flat roofs.
Witham sits about 8 km from Maldon and 11 km from Braintree, and we cover the whole CM8 postcode district and the roads in between.
Choices for your Witham project
- Polycarbonate or acrylic
- Insulated PVC or GRP upstands
- Twin, triple or quad skin
- Fixed or hinged with vent
- Fall-through protection mesh
- Smoke-vent versions available
- Fixed, hinged or vented options
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
Rules and responsibilities in Witham
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about dome rooflights in Witham
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.
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 domes open?
Hinged and vented domes are available, manual or electric.
How do I book a survey in Witham?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Do I need to be at home for the survey in Witham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
