How we approach dome rooflights in Sunbury-on-Thames
For Sunbury-on-Thames 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.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Typical uses for dome rooflights include schools, flats and commercial flat roofs.
Neighbouring towns include Walton-on-Thames (2 km) and Hampton (4 km). We offer a survey date when we reply to your enquiry.
Specification options
- Insulated PVC or GRP upstands
- Fall-through protection mesh
- Clear, opal or tinted
- Polycarbonate or acrylic
- Twin, triple or quad skin
- Fixed, hinged or vented options
- Low cost per unit
Before you order: points to check
- Fire classification matters on some roofs
- Upstand condition decides whether you replace dome only or the whole unit
Building control and safety duties in Sunbury-on-Thames
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.

Common questions
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
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 domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
