Commercial & industrial rooflights in Chelmsford: what is involved?
Our commercial & industrial rooflights service in Chelmsford 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.
Flat, open landscape in much of the East means roofs take the wind, so upstand and seal details matter more than the brand of glass. In Chelmsford, as anywhere, commercial & industrial rooflights are the usual choice for industrial roofs with tired or fragile rooflight sheets.
Jobs in Chelmsford 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 Chelmsford
- Polycarbonate domes
- Mesh or grilles under fragile areas
- GRP or polycarbonate in-plane rooflight sheets
- Modular glass rooflights
- Smoke and natural ventilation vents
- Daylight that reduces daytime lighting
- Planned around working sites
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 Chelmsford
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. 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.
