Dome rooflights in Leigh: what is involved?
Thinking about dome rooflights in Leigh? 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.
Converted mills and warehouses in the North West often have large rooflights or glass roofs that need specialist replacement. Dome rooflights suit older flat roofs with yellowed or leaking domes.
Leigh sits about 3 km from Atherton and 4 km from Tyldesley, and we cover the whole WN7 postcode district and the roads in between.
Specification options
- Fixed or hinged with vent
- Fall-through protection mesh
- Clear, opal or tinted
- Polycarbonate or acrylic
- Twin, triple or quad skin
- Smoke-vent versions available
- Fixed, hinged or vented options
What to check first
- Upstand condition decides whether you replace dome only or the whole unit
- Fire classification matters on some roofs
Regulations for dome rooflights in Leigh
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
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 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.
How do I book a survey in Leigh?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Leigh?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
