Dome rooflights in Cirencester: what is involved?
Our dome rooflights service in Cirencester covers polycarbonate and acrylic domes for flat roofs, new or replacement. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. In Cirencester, as anywhere, dome rooflights are the usual choice for schools, flats and commercial flat roofs.
Cirencester sits about 16 km from Stroud and 21 km from Cheltenham, and we cover the whole GL7 postcode district and the roads in between.

- Insulated PVC or GRP upstands

What to check first

Building control and safety duties in Cirencester
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. 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.

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.
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.
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Can you work alongside my builder in Cirencester?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do you fit dome rooflights in Cirencester?
Yes. We survey and fit dome rooflights in Cirencester and across Gloucestershire. Send your postcode and we will offer a survey date when we reply.
