How we approach dome rooflights in Thetford
For Thetford 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.
Coastal towns in the East of England see salty air, so we specify frame finishes and fixings with exposure in mind. Typical uses for dome rooflights include schools, flats and commercial flat roofs.
Jobs in Thetford 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.
Options we can specify in Thetford
- Fixed or hinged with vent
- Twin, triple or quad skin
- Clear, opal or tinted
- Polycarbonate or acrylic
- Fall-through protection mesh
- Fixed, hinged or vented options
- Light, impact-resistant domes
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 Thetford
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.

Dome rooflights in Thetford: questions
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
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.
Do I need to be at home for the survey in Thetford?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Thetford?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
