Commercial & industrial rooflights in Dyfed: the essentials
Our commercial & industrial rooflights service in Dyfed covers rooflights for warehouses, schools, offices and retail units. We survey every job before fixing the price.
Slate roofs, stone cottages and terraced valleys are typical across Wales, and slim rooflights that sit low in the slates suit them best. Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass.

Planning and building rules in Wales
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.

How the job runs
- Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
- Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common questions
Can you quote from drawings?
Yes, with a site survey to confirm.
Do you supply O&M information?
Yes — product data, manufacturer warranties and maintenance notes are handed over at completion.
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.
Do I need to be at home for the survey in Dyfed?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
