Commercial & industrial rooflights for Highgate: the essentials
For Highgate homes and buildings we offer commercial & industrial rooflights: rooflights for warehouses, schools, offices and retail units. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
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. Commercial & industrial rooflights suit industrial roofs with tired or fragile rooflight sheets.
From Highgate to Hampstead, Kilburn and Holloway, the same survey-first process applies: measure, specify, fix the price, then fit.
Choices for your Highgate project
- Smoke and natural ventilation vents
- GRP or polycarbonate in-plane rooflight sheets
- Modular glass rooflights
- Polycarbonate domes
- Mesh or grilles under fragile areas
- Smoke-vent options where needed
- Planned around working sites
What to check first
- Fire performance of rooflight materials matters near boundaries
- Fragile rooflights are a known fall hazard — work at height must be planned
Rules and responsibilities in Highgate
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.
See our building regulations guide for U-values, glazing limits and self-certification.
