Dome rooflights in Chippenham: what is involved?
Our dome rooflights service in Chippenham 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.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Think of dome rooflights for schools, flats and commercial flat roofs.
Jobs in Chippenham 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
- Clear, opal or tinted
- Fall-through protection mesh
- Insulated PVC or GRP upstands
- Twin, triple or quad skin
- Polycarbonate or acrylic
- Quick replacement on existing upstands
- Fixed, hinged or vented options
Before you order: points to check
- Fire classification matters on some roofs
- Plastic domes have a lower acoustic and thermal performance than glass
Building control and safety duties in Chippenham
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. 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.
Read the planning permission guide before you commit to a design.

Questions about dome rooflights in Chippenham
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on it.
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Do you fit dome rooflights in Chippenham?
Yes. We survey and fit dome rooflights in Chippenham and across Wiltshire. Send your postcode and we will offer a survey date when we reply.
Can you work alongside my builder in Chippenham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
