Commercial & industrial rooflights in Barnet: what is involved?
Thinking about commercial & industrial rooflights in Barnet? 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.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. Commercial & industrial rooflights suit industrial roofs with tired or fragile rooflight sheets.
Jobs in Barnet are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Choices for your Barnet project
- Smoke and natural ventilation vents
- Mesh or grilles under fragile areas
- GRP or polycarbonate in-plane rooflight sheets
- Modular glass rooflights
- Polycarbonate domes
- Replacement of discoloured or fragile sheets
- Barrel vaults, ridge lights and modular glass
Before you order: points to check
- Fragile rooflights are a known fall hazard — work at height must be planned
- Asbestos surveys may be needed on older roofs
Building control and safety duties in Barnet
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 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.
Our planning guide covers each nation in more detail.
