What do commercial & industrial rooflights involve?
Our commercial & industrial rooflights service in Norfolk covers rooflights for warehouses, schools, offices and retail units. We survey every job before fixing the price.
In the East of England, bungalows and chalet bungalows with large flat-roofed extensions are common, and they often suit a long run of rooflights. Flat, open landscape in much of the East means roofs take the wind, so upstand and seal details matter more than the brand of glass.

Planning and building rules in England
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.

How the job runs
- Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
- Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common questions
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.
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 rooflights double as smoke vents?
Some units are certified smoke ventilators. See our smoke-vent rooflights page.
