How we approach dome rooflights in Didcot
Thinking about dome rooflights in Didcot? The short answer: polycarbonate and acrylic domes for flat roofs, new or replacement. The longer answer depends on your roof, which is why we survey before we price.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Think of dome rooflights for schools, flats and commercial flat roofs.
Neighbouring towns include Abingdon (7 km) and Wantage (13 km). We offer a survey date when we reply to your enquiry.

Rules and responsibilities in Didcot
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.
Read the planning permission guide before you commit to a design.

Dome rooflights in Didcot: questions
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Can domes open?
Hinged and vented domes are available, manual or electric.
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on it.
Can you work alongside my builder in Didcot?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Didcot?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
