How we approach dome rooflights in Kingston upon Thames
For Kingston upon 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.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. Think of dome rooflights for older flat roofs with yellowed or leaking domes.
We work across Greater London, including Kingston upon Thames, and in neighbouring towns such as Twickenham and Richmond. Access, parking and how the glass reaches the roof are all checked at the survey.

What to check first

Rules and responsibilities in Kingston upon Thames
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.

Dome rooflights in Kingston upon Thames: questions
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on it.
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
Do I need to be at home for the survey in Kingston upon Thames?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Kingston upon Thames?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
