What do dome rooflights in Witney involve?
Thinking about dome rooflights in Witney? 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.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Think of dome rooflights for older flat roofs with yellowed or leaking domes.
Jobs in Witney 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
- Fixed or hinged with vent
- Fall-through protection mesh
- Twin, triple or quad skin
- Clear, opal or tinted
- Polycarbonate or acrylic
- Suits schools, flats and commercial roofs
- Smoke-vent versions available
What to check first
- Upstand condition decides whether you replace dome only or the whole unit
- Plastic domes have a lower acoustic and thermal performance than glass
Building control and safety duties in Witney
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.

Common questions
Can domes open?
Hinged and vented domes are available, manual or electric.
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
How do I book a survey in Witney?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Witney?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
