Commercial & industrial rooflights for Nelson: the essentials
Commercial & industrial rooflights in Nelson means rooflights for warehouses, schools, offices and retail units. We cover the BB9 district and the rest of Lancashire, with a survey before any price is fixed.
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 commercial & industrial rooflights include industrial roofs with tired or fragile rooflight sheets.
Nelson sits about 3 km from Colne and 4 km from Burnley, and we cover the whole BB9 postcode district and the roads in between.
Specification options
- GRP or polycarbonate in-plane rooflight sheets
- Smoke and natural ventilation vents
- Polycarbonate domes
- Modular glass rooflights
- Mesh or grilles under fragile areas
- Barrel vaults, ridge lights and modular glass
- Planned around working sites
Things we check at survey
- Asbestos surveys may be needed on older roofs
- Non-fragility classification should be confirmed for new products
Building control and safety duties in Nelson
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.

Common questions
Can you quote from drawings?
Yes, with a site survey to confirm.
Are old rooflights a safety risk?
Older plastic rooflight sheets can become brittle. Anyone working on the roof must treat them as fragile unless proven otherwise.
Can rooflights double as smoke vents?
Some units are certified smoke ventilators. See our smoke-vent rooflights page.
How do I book a survey in Nelson?
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 Nelson?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
