Dome rooflights in Seaford: what is involved?
For Seaford 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.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Dome rooflights suit older flat roofs with yellowed or leaking domes.
Seaford sits about 12 km from Rottingdean and 13 km from Eastbourne, and we cover the whole BN25 postcode district and the roads in between.
What you can choose
- Twin, triple or quad skin
- Fall-through protection mesh
- Insulated PVC or GRP upstands
- Fixed or hinged with vent
- Polycarbonate or acrylic
- Suits schools, flats and commercial roofs
- Light, impact-resistant domes
Before you order: points to check
- 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 Seaford
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. Product data for building control is supplied with every quote.
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.
Our planning guide covers each nation in more detail.

Common questions
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.
Can domes open?
Hinged and vented domes are available, manual or electric.
How do I book a survey in Seaford?
