How we approach dome rooflights in Folkestone
For Folkestone 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.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. In Folkestone, as anywhere, dome rooflights are the usual choice for older flat roofs with yellowed or leaking domes.
From Folkestone to Dover, Ashford, Kent and Deal, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Twin, triple or quad skin
- Polycarbonate or acrylic
- Insulated PVC or GRP upstands
- Fixed or hinged with vent
- Fall-through protection mesh
- Light, impact-resistant domes
- Suits schools, flats and commercial roofs
Things we check at survey
- Upstand condition decides whether you replace dome only or the whole unit
- Old domes may be fragile — treat as fragile until checked
Rules and responsibilities in Folkestone
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.
Read the planning permission guide before you commit to a design.

Common questions
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on it.
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.
Can you work alongside my builder in Folkestone?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Folkestone?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
