Commercial & industrial rooflights for Carmarthen: the essentials
Our commercial & industrial rooflights service in Carmarthen covers rooflights for warehouses, schools, offices and retail units. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Slate roofs, stone cottages and terraced valleys are typical across Wales, and slim rooflights that sit low in the slates suit them best. In Carmarthen, as anywhere, commercial & industrial rooflights are the usual choice for industrial roofs with tired or fragile rooflight sheets.
We work across Dyfed, including Carmarthen, and in neighbouring towns such as Llanelli and Ammanford. Access, parking and how the glass reaches the roof are all checked at the survey.
Choices for your Carmarthen project
- Polycarbonate domes
- Continuous barrel-vault rooflights
- GRP or polycarbonate in-plane rooflight sheets
- Mesh or grilles under fragile areas
- Smoke and natural ventilation vents
- Planned around working sites
- Daylight that reduces daytime lighting
What to check first
- Asbestos surveys may be needed on older roofs
- Non-fragility classification should be confirmed for new products
Rules and responsibilities in Carmarthen
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. Fire classification of rooflight materials near boundaries is checked at specification.

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.
Do you work out of hours?
For occupied buildings we can plan phased or out-of-hours working where access allows.
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 fit commercial & industrial rooflights in Carmarthen?
Yes. We survey and fit commercial & industrial rooflights in Carmarthen and across Dyfed. Send your postcode and we will offer a survey date when we reply.
Do I need to be at home for the survey in Carmarthen?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
