What do commercial & industrial rooflights in Chiswick involve?
Commercial & industrial rooflights in Chiswick means rooflights for warehouses, schools, offices and retail units. We cover the W4 district and the rest of Greater London, with a survey before any price is fixed.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Think of commercial & industrial rooflights for industrial roofs with tired or fragile rooflight sheets.
We work across Greater London, including Chiswick, and in neighbouring towns such as Hammersmith and Acton. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Polycarbonate domes
- GRP or polycarbonate in-plane rooflight sheets
- Mesh or grilles under fragile areas
- Modular glass rooflights
- Continuous barrel-vault rooflights
- Replacement of discoloured or fragile sheets
- Planned around working sites
Before you order: points to check
- Asbestos surveys may be needed on older roofs
- Fire performance of rooflight materials matters near boundaries
Building control and safety duties in Chiswick
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.
