What are commercial & industrial rooflights?
Across Mid Glamorgan, our commercial & industrial rooflights work covers rooflights for warehouses, schools, offices and retail units. Survey first, fixed price second, fitting third.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass.

Planning and building rules in Wales
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 non-domestic buildings in Wales, Approved Document L sets limiting U-values for rooflights and roof ventilators; we supply the manufacturer's data for the building control submission. Fragile-roof safety and access are planned before work starts.

Common questions
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 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.
Can rooflights double as smoke vents?
Some units are certified smoke ventilators. See our smoke-vent rooflights page.
Do you work out of hours?
For occupied buildings we can plan phased or out-of-hours working where access allows.
