How we approach dome rooflights in Northwich
We handle dome rooflights across Cheshire, including Northwich. In short: polycarbonate and acrylic domes for flat roofs, new or replacement. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Stone and brick terraces are typical across the North West, and roof windows in rear slopes are a common way to light attic rooms. Typical uses for dome rooflights include schools, flats and commercial flat roofs.
Northwich sits about 7 km from Winsford and 15 km from Warrington, and we cover the whole CW9 postcode district and the roads in between.
Options we can specify in Northwich
- Clear, opal or tinted
- Fixed or hinged with vent
- Fall-through protection mesh
- Twin, triple or quad skin
- Insulated PVC or GRP upstands
- Low cost per unit
- Smoke-vent versions available
Things we check at survey
- Old domes may be fragile — treat as fragile until checked
- Plastic domes have a lower acoustic and thermal performance than glass
Regulations for dome rooflights in Northwich
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.
Read the planning permission guide before you commit to a design.

Common questions
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.
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
Do I need to be at home for the survey in Northwich?
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 Northwich?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
