What do dome rooflights involve?
Dome rooflights in Oxfordshire means polycarbonate and acrylic domes for flat roofs, new or replacement. Every quote follows a survey of the roof and the room below.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice.

Planning and building rules in England
For non-domestic buildings, planning depends on the building and its location; building regulations cover thermal performance and the fire classification of rooflights near boundaries. 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.

- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common questions
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.
Should I replace a dome or switch to glass?
A dome is cheaper and quick; glass gives a clear view and better performance. On a tight budget, or a commercial roof with many units, domes remain sensible.
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
Do you fit dome rooflights across Oxfordshire?
Yes. We survey and fit dome rooflights across Oxfordshire, including Oxford, Banbury, Abingdon.
