Commercial & industrial rooflights in Northampton: what is involved?
We handle commercial & industrial rooflights across Northamptonshire, including Northampton. In short: rooflights for warehouses, schools, offices and retail units. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Many Midlands semis have had a single-storey rear extension added, and a larger flat rooflight or lantern is often the change that makes it feel finished. Typical uses for commercial & industrial rooflights include warehouses, schools, offices and retail units.
We cover all of Northampton and the NN1 district, and nearby Wellingborough and Towcester.
Choices for your Northampton project
- Modular glass rooflights
- Continuous barrel-vault rooflights
- Mesh or grilles under fragile areas
- Smoke and natural ventilation vents
- GRP or polycarbonate in-plane rooflight sheets
- Planned around working sites
- Smoke-vent options where needed
What to check first
- Fragile rooflights are a known fall hazard — work at height must be planned
- Fire performance of rooflight materials matters near boundaries
Regulations for commercial & industrial rooflights in Northampton
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about commercial & industrial rooflights in Northampton
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 work out of hours?
For occupied buildings we can plan phased or out-of-hours working where access allows.
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.
How do I book a survey in Northampton?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Northampton?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
