Dome rooflights for Blackheath: the essentials
For Blackheath homes and buildings we offer dome rooflights: polycarbonate and acrylic domes for flat roofs, new or replacement. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Think of dome rooflights for older flat roofs with yellowed or leaking domes.
Jobs in Blackheath 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 Blackheath project
- Clear, opal or tinted
- Insulated PVC or GRP upstands
- Twin, triple or quad skin
- Fall-through protection mesh
- Fixed or hinged with vent
- Quick replacement on existing upstands
- Fixed, hinged or vented options
Before you order: points to check
- Plastic domes have a lower acoustic and thermal performance than glass
- Fire classification matters on some roofs
Rules and responsibilities in Blackheath
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.
Read the planning permission guide before you commit to a design.

Dome rooflights in Blackheath: questions
Can domes open?
Hinged and vented domes are available, manual or electric.
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
How do I book a survey in Blackheath?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Do I need to be at home for the survey in Blackheath?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
