What do dome rooflights in Flitwick involve?
Thinking about dome rooflights in Flitwick? 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. Typical uses for dome rooflights include older flat roofs with yellowed or leaking domes.
Flitwick is around 15 km from Luton, and we survey and fit throughout that part of Bedfordshire, including the MK45 district.
Options we can specify in Flitwick
- Clear, opal or tinted
- Fall-through protection mesh
- Polycarbonate or acrylic
- Fixed or hinged with vent
- Insulated PVC or GRP upstands
- Quick replacement on existing upstands
- Fixed, hinged or vented options
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
Building control and safety duties in Flitwick
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. 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.

Dome rooflights in Flitwick: 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.
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 Flitwick?
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 Flitwick?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
