Commercial & industrial rooflights in Watford: what is involved?
For Watford homes and buildings we offer commercial & industrial rooflights: rooflights for warehouses, schools, offices and retail units. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. In Watford, as anywhere, commercial & industrial rooflights are the usual choice for warehouses, schools, offices and retail units.
We cover all of Watford and the WD17 district, and nearby Bushey and Rickmansworth.
What you can choose
- Polycarbonate domes
- Smoke and natural ventilation vents
- Continuous barrel-vault rooflights
- Mesh or grilles under fragile areas
- Modular glass rooflights
- Smoke-vent options where needed
- Fall-protection planning included
Things we check at survey
- Non-fragility classification should be confirmed for new products
- Asbestos surveys may be needed on older roofs
Rules and responsibilities in Watford
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.
