How we approach dome rooflights in Rochester
We handle dome rooflights across Kent, including Rochester. In short: polycarbonate and acrylic domes for flat roofs, new or replacement. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. In Rochester, as anywhere, dome rooflights are the usual choice for schools, flats and commercial flat roofs.
Neighbouring towns include Chatham (2 km) and Strood (2 km). We offer a survey date when we reply to your enquiry.
Specification options
- Fixed or hinged with vent
- Polycarbonate or acrylic
- Clear, opal or tinted
- Twin, triple or quad skin
- Fall-through protection mesh
- Light, impact-resistant domes
- Quick replacement on existing upstands
Things we check at survey
- Upstand condition decides whether you replace dome only or the whole unit
- Plastic domes have a lower acoustic and thermal performance than glass
Regulations for dome rooflights in Rochester
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.

Dome rooflights in Rochester: questions
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
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.
Can you work alongside my builder in Rochester?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Rochester?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
