How we approach commercial & industrial rooflights in Lisburn
We handle commercial & industrial rooflights across County Antrim, including Lisburn. In short: rooflights for warehouses, schools, offices and retail units. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Conservation areas and listed buildings in Northern Ireland are excluded from householder permitted development, so we check before quoting. Typical uses for commercial & industrial rooflights include industrial roofs with tired or fragile rooflight sheets.
Jobs in Lisburn 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.
Options we can specify in Lisburn
- Continuous barrel-vault rooflights
- Mesh or grilles under fragile areas
- Polycarbonate domes
- Modular glass rooflights
- Smoke and natural ventilation vents
- Fall-protection planning included
- Barrel vaults, ridge lights and modular glass
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 Lisburn
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. We confirm the route for your building before ordering.
For non-domestic buildings in Northern Ireland, Technical Booklet F2 covers energy performance; we supply the manufacturer's data for building control. Fire classification of rooflight materials near boundaries is checked at specification.
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.
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 Lisburn?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Do I need to be at home for the survey in Lisburn?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
