How we approach commercial & industrial rooflights in Carshalton
Thinking about commercial & industrial rooflights in Carshalton? 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.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Think of commercial & industrial rooflights for industrial roofs with tired or fragile rooflight sheets.
Carshalton sits about 1 km from Wallington and 1 km from Sutton, and we cover the whole SM5 postcode district and the roads in between.
What you can choose
- GRP or polycarbonate in-plane rooflight sheets
- Smoke and natural ventilation vents
- Continuous barrel-vault rooflights
- Mesh or grilles under fragile areas
- Polycarbonate domes
- Planned around working sites
- Daylight that reduces daytime lighting
What to check first
- Fragile rooflights are a known fall hazard — work at height must be planned
- Asbestos surveys may be needed on older roofs

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. Fragile-roof safety and access are planned before work starts.
