Dome rooflights for Southampton: the essentials
Dome rooflights in Southampton means polycarbonate and acrylic domes for flat roofs, new or replacement. We cover the SO14 district and the rest of Hampshire, with a survey before any price is fixed.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. In Southampton, as anywhere, dome rooflights are the usual choice for older flat roofs with yellowed or leaking domes.
We cover all of Southampton and the SO14 district, and nearby Hythe and Totton.
Options we can specify in Southampton
- Twin, triple or quad skin
- Fall-through protection mesh
- Polycarbonate or acrylic
- Fixed or hinged with vent
- Insulated PVC or GRP upstands
- Smoke-vent versions available
- Quick replacement on existing upstands
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
Rules and responsibilities in Southampton
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. Fire classification of rooflight materials near boundaries is checked at specification.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
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.
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
Can domes open?
Hinged and vented domes are available, manual or electric.
