Dome rooflights in Braintree: what is involved?
Our dome rooflights service in Braintree covers polycarbonate and acrylic domes for flat roofs, new or replacement. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Barn conversions and timber-framed homes across the East often call for conservation rooflights or bespoke glass. Dome rooflights suit older flat roofs with yellowed or leaking domes.
Jobs in Braintree 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.
What you can choose
- Insulated PVC or GRP upstands
- Fall-through protection mesh
- Twin, triple or quad skin
- Fixed or hinged with vent
- Clear, opal or tinted
- Smoke-vent versions available
- Fixed, hinged or vented options
What to check first
- Fire classification matters on some roofs
- Old domes may be fragile — treat as fragile until checked
Rules and responsibilities in Braintree
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.
See our building regulations guide for U-values, glazing limits and self-certification.
What do dome rooflights cost in Braintree?

Dome rooflights in Braintree: questions
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.
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
Do you fit dome rooflights in Braintree?
Yes. We survey and fit dome rooflights in Braintree and across Essex. Send your postcode and we will offer a survey date when we reply.
Can you work alongside my builder in Braintree?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
