How we approach dome rooflights in Monmouth
Thinking about dome rooflights in Monmouth? 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.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Dome rooflights suit older flat roofs with yellowed or leaking domes.
Jobs in Monmouth 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.
Options we can specify in Monmouth
- Twin, triple or quad skin
- Insulated PVC or GRP upstands
- Polycarbonate or acrylic
- Fixed or hinged with vent
- Fall-through protection mesh
- Low cost per unit
- Light, impact-resistant domes
Things we check at survey
- Plastic domes have a lower acoustic and thermal performance than glass
- Upstand condition decides whether you replace dome only or the whole unit
Regulations for dome rooflights in Monmouth

For non-domestic buildings in Wales, Approved Document L sets limiting U-values for rooflights and roof ventilators; we supply the manufacturer's data for the building control submission. Fragile-roof safety and access are planned before work starts.

Questions about dome rooflights in Monmouth
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
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.
Can you work alongside my builder in Monmouth?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Monmouth?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
