What do dome rooflights in Swanley involve?
Dome rooflights in Swanley means polycarbonate and acrylic domes for flat roofs, new or replacement. We cover the BR8 district and the rest of Kent, with a survey before any price is fixed.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Think of dome rooflights for schools, flats and commercial flat roofs.
Jobs in Swanley 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.
Choices for your Swanley project
- Insulated PVC or GRP upstands
- Twin, triple or quad skin
- Polycarbonate or acrylic
- Clear, opal or tinted
- Fall-through protection mesh
- Fixed, hinged or vented options
- Smoke-vent versions available
Things we check at survey
- Old domes may be fragile — treat as fragile until checked
- Upstand condition decides whether you replace dome only or the whole unit
Building control and safety duties in Swanley
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. Fragile-roof safety and access are planned before work starts.
See our building regulations guide for U-values, glazing limits and self-certification.
