Dome rooflights for Purley: the essentials
Thinking about dome rooflights in Purley? 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.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. Dome rooflights suit schools, flats and commercial flat roofs.
Purley is around 19 km from central London, and we survey and fit throughout that part of Greater London, including the CR8 district.
Choices for your Purley project
- Polycarbonate or acrylic
- Fall-through protection mesh
- Twin, triple or quad skin
- Fixed or hinged with vent
- Insulated PVC or GRP upstands
- Light, impact-resistant domes
- Suits schools, flats and commercial roofs
Before you order: points to check
- Plastic domes have a lower acoustic and thermal performance than glass
- Old domes may be fragile — treat as fragile until checked
Building control and safety duties in Purley
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. 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.

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.

No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on it.
