Commercial & industrial rooflights in Lewisham: what is involved?
Our commercial & industrial rooflights service in Lewisham 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.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Commercial & industrial rooflights suit industrial roofs with tired or fragile rooflight sheets.
Lewisham is around 8 km from central London, and we survey and fit throughout that part of Greater London, including the SE13 district.
Choices for your Lewisham project
- Mesh or grilles under fragile areas
- Modular glass rooflights
- Polycarbonate domes
- Continuous barrel-vault rooflights
- Smoke and natural ventilation vents
- Barrel vaults, ridge lights and modular glass
- Planned around working sites
Before you order: points to check
- Non-fragility classification should be confirmed for new products
- Fragile rooflights are a known fall hazard — work at height must be planned
Rules and responsibilities in Lewisham
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. Fragile-roof safety and access are planned before work starts.
Our planning guide covers each nation in more detail.

Common questions
Do you supply O&M information?
Yes — product data, manufacturer warranties and maintenance notes are handed over at completion.
Are old rooflights a safety risk?
Older plastic rooflight sheets can become brittle. Anyone working on the roof must treat them as fragile unless proven otherwise.
Can rooflights double as smoke vents?
Some units are certified smoke ventilators. See our smoke-vent rooflights page.
Do I need to be at home for the survey in Lewisham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Lewisham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
