Commercial & industrial rooflights for Portsmouth: the essentials
We handle commercial & industrial rooflights across Hampshire, including Portsmouth. In short: rooflights for warehouses, schools, offices and retail units. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Think of commercial & industrial rooflights for industrial roofs with tired or fragile rooflight sheets.
We work across Hampshire, including Portsmouth, and in neighbouring towns such as Gosport and Fareham. Access, parking and how the glass reaches the roof are all checked at the survey.
Options we can specify in Portsmouth
- Modular glass rooflights
- Continuous barrel-vault rooflights
- Mesh or grilles under fragile areas
- Polycarbonate domes
- GRP or polycarbonate in-plane rooflight sheets
- Fall-protection planning included
- Planned around working sites
What to check first
- Fire performance of rooflight materials matters near boundaries
- Non-fragility classification should be confirmed for new products
Building control and safety duties in Portsmouth
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. Fire classification of rooflight materials near boundaries is checked at specification.
Read the planning permission guide before you commit to a design.
