What do commercial & industrial rooflights in Bow involve?
We handle commercial & industrial rooflights across Greater London, including Bow. In short: rooflights for warehouses, schools, offices and retail units. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Typical uses for commercial & industrial rooflights include warehouses, schools, offices and retail units.
Jobs in Bow 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.
Specification options
- Smoke and natural ventilation vents
- Continuous barrel-vault rooflights
- Mesh or grilles under fragile areas
- GRP or polycarbonate in-plane rooflight sheets
- Modular glass rooflights
- Fall-protection planning included
- Replacement of discoloured or fragile sheets
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 Bow
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. Fire classification of rooflight materials near boundaries is checked at specification.
Read the planning permission guide before you commit to a design.

Common questions
Can rooflights double as smoke vents?
Some units are certified smoke ventilators. See our smoke-vent rooflights page.
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 you replace old warehouse rooflight sheets?
Yes. We match the roof profile, replace discoloured or damaged sheets and plan safe access while the building stays in use.
Do I need to be at home for the survey in Bow?
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 Bow?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
