Commercial & industrial rooflights in Hertfordshire: the essentials
Across Hertfordshire, our commercial & industrial rooflights work covers rooflights for warehouses, schools, offices and retail units. Survey first, fixed price second, fitting third.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens.

Planning and building rules in England
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. 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. Fire classification of rooflight materials near boundaries is checked at specification.

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 quote from drawings?
Yes, with a site survey to confirm.
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.
Can rooflights double as smoke vents?
Some units are certified smoke ventilators. See our smoke-vent rooflights page.
Do I need to be at home for the survey in Hertfordshire?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
