Dome rooflights for Tonbridge: the essentials
Our dome rooflights service in Tonbridge 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.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. In Tonbridge, as anywhere, dome rooflights are the usual choice for older flat roofs with yellowed or leaking domes.
Tonbridge is around 19 km from Maidstone, and we survey and fit throughout that part of Kent, including the TN9 district.
Options we can specify in Tonbridge
- Twin, triple or quad skin
- Insulated PVC or GRP upstands

Things we check at survey

Rules and responsibilities in Tonbridge
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about dome rooflights in Tonbridge
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Can domes open?
Hinged and vented domes are available, manual or electric.
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on it.
Do I need to be at home for the survey in Tonbridge?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Tonbridge?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
