What are commercial & industrial rooflights?
Commercial rooflights cover the products used on non-domestic roofs: in-plane rooflight sheets in profiled metal roofs, continuous barrel-vault and ridge rooflights, modular flat-glass units and dome rooflights on flat roofs.
Good daylight cuts artificial lighting during the day and improves working conditions. On older buildings, discoloured or fragile rooflight sheets are a safety issue as well as a light issue.
We survey, specify and install for owners, facilities managers and contractors, and plan access and fall protection as part of the job.

What options are there?
- GRP or polycarbonate in-plane rooflight sheets
- Continuous barrel-vault rooflights
- Modular glass rooflights
- Polycarbonate domes
- Smoke and natural ventilation vents
- Mesh or grilles under fragile areas
What should you check before you order?
- Fragile rooflights are a known fall hazard — work at height must be planned
- Non-fragility classification should be confirmed for new products
- Fire performance of rooflight materials matters near boundaries
- Asbestos surveys may be needed on older roofs
Planning and building-regulation rules differ between England, Wales, Scotland and Northern Ireland. Our planning guide and building regulations guide set out each nation's position.

Commercial & industrial rooflights: common questions
Can you replace old warehouse rooflight sheets?
Yes. We match the roof profile, replace discoloured or damaged sheets and plan safe access while the building stays in use.
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.
Do you work out of hours?
For occupied buildings we can plan phased or out-of-hours working where access allows.
Can rooflights double as smoke vents?
Some units are certified smoke ventilators. See our smoke-vent rooflights page.
Do you supply O&M information?
Yes — product data, manufacturer warranties and maintenance notes are handed over at completion.
Can you quote from drawings?
Yes, with a site survey to confirm.
