What do commercial & industrial rooflights in St Austell involve?
For St Austell homes and buildings we offer commercial & industrial rooflights: rooflights for warehouses, schools, offices and retail units. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Commercial & industrial rooflights suit warehouses, schools, offices and retail units.
From St Austell to Bodmin, Truro and Newquay, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Modular glass rooflights
- Mesh or grilles under fragile areas
- Smoke and natural ventilation vents
- GRP or polycarbonate in-plane rooflight sheets
- Polycarbonate domes
- Replacement of discoloured or fragile sheets
- Barrel vaults, ridge lights and modular glass
Things we check at survey
- Fire performance of rooflight materials matters near boundaries
- Asbestos surveys may be needed on older roofs
Building control and safety duties in St Austell
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.
Read the planning permission guide before you commit to a design.

Questions about commercial & industrial rooflights in St Austell
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 work out of hours?
For occupied buildings we can plan phased or out-of-hours working where access allows.
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 St Austell?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in St Austell?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
