What do dome rooflights in Putney involve?
Our dome rooflights service in Putney 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.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Dome rooflights suit older flat roofs with yellowed or leaking domes.
From Putney to Barnes, Fulham and Wandsworth, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Fixed or hinged with vent
- Fall-through protection mesh
- Insulated PVC or GRP upstands
- Twin, triple or quad skin
- Clear, opal or tinted
- Light, impact-resistant domes
- Smoke-vent versions available
Things we check at survey
- Plastic domes have a lower acoustic and thermal performance than glass
- Fire classification matters on some roofs
Regulations for dome rooflights in Putney
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.

Common 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.
Do you fit dome rooflights in Putney?
Yes. We survey and fit dome rooflights in Putney and across Greater London. Send your postcode and we will offer a survey date when we reply.
Can you work alongside my builder in Putney?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
