What do commercial & industrial rooflights in Stevenage involve?
Thinking about commercial & industrial rooflights in Stevenage? The short answer: rooflights for warehouses, schools, offices and retail units. The longer answer depends on your roof, which is why we survey before we price.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Commercial & industrial rooflights suit warehouses, schools, offices and retail units.
We work across Hertfordshire, including Stevenage, and in neighbouring towns such as Hitchin and Letchworth Garden City. Access, parking and how the glass reaches the roof are all checked at the survey.
Options we can specify in Stevenage
- Smoke and natural ventilation vents
- Mesh or grilles under fragile areas
- Continuous barrel-vault rooflights
- Polycarbonate domes
- GRP or polycarbonate in-plane rooflight sheets
- Replacement of discoloured or fragile sheets
- Barrel vaults, ridge lights and modular glass
What to check first
- Fragile rooflights are a known fall hazard — work at height must be planned
- Fire performance of rooflight materials matters near boundaries
Regulations for commercial & industrial rooflights in Stevenage
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. Fragile-roof safety and access are planned before work starts.
See our building regulations guide for U-values, glazing limits and self-certification.
