How we approach dome rooflights in Wantage
We handle dome rooflights across Oxfordshire, including Wantage. In short: polycarbonate and acrylic domes for flat roofs, new or replacement. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. In Wantage, as anywhere, dome rooflights are the usual choice for older flat roofs with yellowed or leaking domes.
Jobs in Wantage are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Specification options
- Twin, triple or quad skin
- Polycarbonate or acrylic
- Insulated PVC or GRP upstands
- Clear, opal or tinted
- Fall-through protection mesh
- 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
- Old domes may be fragile — treat as fragile until checked
Rules and responsibilities in Wantage
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. 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
Can domes open?
Hinged and vented domes are available, manual or electric.
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Can you work alongside my builder in Wantage?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do you fit dome rooflights in Wantage?
Yes. We survey and fit dome rooflights in Wantage and across Oxfordshire. Send your postcode and we will offer a survey date when we reply.
