Commercial & industrial rooflights for Dulwich: the essentials
Our commercial & industrial rooflights service in Dulwich covers rooflights for warehouses, schools, offices and retail units. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. Commercial & industrial rooflights suit industrial roofs with tired or fragile rooflight sheets.
Dulwich sits about 2 km from Brixton and 3 km from Peckham, and we cover the whole SE21 postcode district and the roads in between.
Specification options
- Mesh or grilles under fragile areas
- GRP or polycarbonate in-plane rooflight sheets
- Continuous barrel-vault rooflights
- Modular glass rooflights
- Smoke and natural ventilation vents
- Barrel vaults, ridge lights and modular glass
- Daylight that reduces daytime lighting
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 Dulwich
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. Product data for building control is supplied with every quote.
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.
