How we approach commercial & industrial rooflights in Belfast
We handle commercial & industrial rooflights across County Antrim, including Belfast. 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.
Belfast is the main town we list in County Antrim; we also cover nearby Castlereagh and Newtownabbey.
Specification options
- GRP or polycarbonate in-plane rooflight sheets
- Polycarbonate domes
- Modular glass rooflights
- Continuous barrel-vault rooflights
- Smoke and natural ventilation vents
- Planned around working sites
- Fall-protection planning included
What to check first
- Asbestos surveys may be needed on older roofs
- Non-fragility classification should be confirmed for new products
Regulations for commercial & industrial rooflights in Belfast
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.
