How we approach commercial & industrial rooflights in Balham
Thinking about commercial & industrial rooflights in Balham? 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.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Commercial & industrial rooflights suit warehouses, schools, offices and retail units.
From Balham to Clapham, Streatham and Brixton, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Balham
- Mesh or grilles under fragile areas
- Modular glass rooflights
- Smoke and natural ventilation vents
- GRP or polycarbonate in-plane rooflight sheets
- Polycarbonate domes
- Smoke-vent options where needed
- Daylight that reduces daytime lighting
Things we check at survey
- Non-fragility classification should be confirmed for new products
- Fire performance of rooflight materials matters near boundaries
Regulations for commercial & industrial rooflights in Balham
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.
