Commercial & industrial rooflights in Harrow: what is involved?
We handle commercial & industrial rooflights across Greater London, including Harrow. In short: rooflights for warehouses, schools, offices and retail units. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
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. Typical uses for commercial & industrial rooflights include warehouses, schools, offices and retail units.
Harrow is around 16 km from central London, and we survey and fit throughout that part of Greater London, including the HA2 district.
What you can choose
- GRP or polycarbonate in-plane rooflight sheets
- Modular glass rooflights
- Smoke and natural ventilation vents
- Continuous barrel-vault rooflights
- Mesh or grilles under fragile areas
- Replacement of discoloured or fragile sheets
- 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
Building control and safety duties in Harrow
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.
