What do commercial & industrial rooflights in Streatham involve?
Thinking about commercial & industrial rooflights in Streatham? 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. In Streatham, as anywhere, commercial & industrial rooflights are the usual choice for warehouses, schools, offices and retail units.
Neighbouring towns include Balham (2 km) and Clapham (4 km). We offer a survey date when we reply to your enquiry.
What you can choose
- Mesh or grilles under fragile areas
- Smoke and natural ventilation vents
- Continuous barrel-vault rooflights
- Modular glass rooflights
- Polycarbonate domes
- Smoke-vent options where needed
- Daylight that reduces daytime lighting
Things we check at survey
- Fragile rooflights are a known fall hazard — work at height must be planned
- Fire performance of rooflight materials matters near boundaries
Regulations for commercial & industrial rooflights in Streatham
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.
See our building regulations guide for U-values, glazing limits and self-certification.
