Dome rooflights in Dunstable: what is involved?
For Dunstable 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.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Think of dome rooflights for older flat roofs with yellowed or leaking domes.
From Dunstable to Luton, Leighton Buzzard and Flitwick, the same survey-first process applies: measure, specify, fix the price, then fit.
Choices for your Dunstable project
- Polycarbonate or acrylic
- Fixed or hinged with vent
- Twin, triple or quad skin
- Clear, opal or tinted
- Insulated PVC or GRP upstands
- Quick replacement on existing upstands
- Suits schools, flats and commercial roofs
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
Rules and responsibilities in Dunstable
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 Dunstable
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
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.
How do I book a survey in Dunstable?
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 Dunstable?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
