How we approach dome rooflights in Christchurch
Dome rooflights in Christchurch means polycarbonate and acrylic domes for flat roofs, new or replacement. We cover the BH23 district and the rest of Dorset, with a survey before any price is fixed.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. In Christchurch, as anywhere, dome rooflights are the usual choice for older flat roofs with yellowed or leaking domes.
Neighbouring towns include Bournemouth (7 km) and New Milton (8 km). We offer a survey date when we reply to your enquiry.

Building control and safety duties in Christchurch
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
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
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.
