What do commercial & industrial rooflights involve?
Commercial & industrial rooflights in Wiltshire means rooflights for warehouses, schools, offices and retail units. Every quote follows a survey of the roof and the room below.
Many South West towns mix Georgian and Victorian terraces with modern estates, so the right product differs street by street. Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs.

Planning and building rules in England
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 buildings other than dwellings, Approved Document L Volume 2 sets limiting U-values of 2.2 W/m²K for rooflights and 3.0 W/m²K for roof ventilators, including smoke vents. 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
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.
Do I need to be at home for the survey in Wiltshire?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
