What do dome rooflights in Hailsham involve?
Thinking about dome rooflights in Hailsham? 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.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. In Hailsham, as anywhere, dome rooflights are the usual choice for older flat roofs with yellowed or leaking domes.
From Hailsham to Eastbourne, Seaford and Bexhill-on-Sea, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Hailsham
- Clear, opal or tinted
- Fall-through protection mesh
- Insulated PVC or GRP upstands
- Polycarbonate or acrylic
- Fixed or hinged with vent
- Smoke-vent versions available
- Fixed, hinged or vented options
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 Hailsham
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 Hailsham: 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.
How do I book a survey in Hailsham?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Hailsham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
