How we approach dome rooflights in Hatfield
Dome rooflights in Hatfield means polycarbonate and acrylic domes for flat roofs, new or replacement. We cover the AL10 district and the rest of Hertfordshire, with a survey before any price is fixed.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Think of dome rooflights for schools, flats and commercial flat roofs.
Neighbouring towns include Welwyn Garden City (4 km) and St Albans (8 km). We offer a survey date when we reply to your enquiry.

Building control and safety duties in Hatfield
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.
Our planning guide covers each nation in more detail.

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.
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 I need to be at home for the survey in Hatfield?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Hatfield?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
