How we approach commercial & industrial rooflights in Northolt
We handle commercial & industrial rooflights across Greater London, including Northolt. 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 industrial roofs with tired or fragile rooflight sheets.
We work across Greater London, including Northolt, and in neighbouring towns such as Greenford and Harrow. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Continuous barrel-vault rooflights
- Modular glass rooflights
- GRP or polycarbonate in-plane rooflight sheets
- Smoke and natural ventilation vents
- Polycarbonate domes
- Fall-protection planning included
- Planned around working sites
Things we check at survey
- Asbestos surveys may be needed on older roofs
- Fire performance of rooflight materials matters near boundaries
Regulations for commercial & industrial rooflights in Northolt
For non-domestic buildings, planning depends on the building and its location; building regulations cover thermal performance and the fire classification of rooflights near boundaries. 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.

Common questions
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.
Do you supply O&M information?
Yes — product data, manufacturer warranties and maintenance notes are handed over at completion.
Do you work out of hours?
For occupied buildings we can plan phased or out-of-hours working where access allows.
Do I need to be at home for the survey in Northolt?
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 Northolt?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
