Commercial & industrial rooflights for Cardiff: the essentials
Thinking about commercial & industrial rooflights in Cardiff? The short answer: rooflights for warehouses, schools, offices and retail units. The longer answer depends on your roof, which is why we survey before we price.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. In Cardiff, as anywhere, commercial & industrial rooflights are the usual choice for warehouses, schools, offices and retail units.
Cardiff is the main town we list in South Glamorgan; we also cover nearby Penarth and Dinas Powys.
Choices for your Cardiff project
- Polycarbonate domes
- Smoke and natural ventilation vents
- GRP or polycarbonate in-plane rooflight sheets
- Modular glass rooflights
- Mesh or grilles under fragile areas
- Planned around working sites
- Smoke-vent options where needed
Things we check at survey
- Non-fragility classification should be confirmed for new products
- Asbestos surveys may be needed on older roofs
Regulations for commercial & industrial rooflights in Cardiff
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. 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. Fire classification of rooflight materials near boundaries is checked at specification.
See our building regulations guide for U-values, glazing limits and self-certification.

Commercial & industrial rooflights in Cardiff: 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.
Do you supply O&M information?
Yes — product data, manufacturer warranties and maintenance notes are handed over at completion.
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.
How do I book a survey in Cardiff?
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 Cardiff?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
