Dome rooflights in Bath: what is involved?
For Bath 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.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. In Bath, as anywhere, dome rooflights are the usual choice for schools, flats and commercial flat roofs.
Bath is the main town we list in Somerset; we also cover nearby Trowbridge and Kingswood.
What you can choose
- Twin, triple or quad skin
- Polycarbonate or acrylic
- Fall-through protection mesh
- Insulated PVC or GRP upstands
- Clear, opal or tinted
- Smoke-vent versions available
- Low cost per unit
Before you order: points to check
- Plastic domes have a lower acoustic and thermal performance than glass
- Upstand condition decides whether you replace dome only or the whole unit
Building control and safety duties in Bath
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. Fire classification of rooflight materials near boundaries is checked at specification.
See our building regulations guide for U-values, glazing limits and self-certification.

Dome rooflights in Bath: questions
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Can domes open?
Hinged and vented domes are available, manual or electric.
Do I need to be at home for the survey in Bath?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Bath?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
