What do commercial & industrial rooflights in Hertford involve?
Our commercial & industrial rooflights service in Hertford covers rooflights for warehouses, schools, offices and retail units. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Typical uses for commercial & industrial rooflights include industrial roofs with tired or fragile rooflight sheets.
Jobs in Hertford are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
What you can choose
- Polycarbonate domes
- GRP or polycarbonate in-plane rooflight sheets
- Mesh or grilles under fragile areas
- Continuous barrel-vault rooflights
- Modular glass rooflights
- Barrel vaults, ridge lights and modular glass
- Planned around working sites
What to check first
- Non-fragility classification should be confirmed for new products
- Fragile rooflights are a known fall hazard — work at height must be planned
Building control and safety duties in Hertford
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.
Our planning guide covers each nation in more detail.

Common questions
Do you supply O&M information?
Yes — product data, manufacturer warranties and maintenance notes are handed over at completion.
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 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 you work alongside my builder in Hertford?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Hertford?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
