Dome rooflights for Farnworth: the essentials
For Farnworth homes and buildings we offer dome rooflights: polycarbonate and acrylic domes for flat roofs, new or replacement. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
The North West gets more rain than most of England, so upstand height, membrane detailing and rain sensors on opening units are not optional extras. Dome rooflights suit schools, flats and commercial flat roofs.
Neighbouring towns include Walkden (4 km) and Bolton (4 km). We offer a survey date when we reply to your enquiry.
Specification options
- Insulated PVC or GRP upstands
- Clear, opal or tinted
- Polycarbonate or acrylic
- Fall-through protection mesh
- Fixed or hinged with vent
- Low cost per unit
- Fixed, hinged or vented options
What to check first
- Upstand condition decides whether you replace dome only or the whole unit
- Old domes may be fragile — treat as fragile until checked
Regulations for dome rooflights in Farnworth
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.

Questions about dome rooflights in Farnworth
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
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.
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
Can you work alongside my builder in Farnworth?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Farnworth?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
