Commercial & industrial rooflights for Portishead: the essentials
Our commercial & industrial rooflights service in Portishead 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.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. In Portishead, as anywhere, commercial & industrial rooflights are the usual choice for warehouses, schools, offices and retail units.
Jobs in Portishead 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.
Choices for your Portishead project
- Polycarbonate domes
- GRP or polycarbonate in-plane rooflight sheets
- Continuous barrel-vault rooflights
- Modular glass rooflights
- Mesh or grilles under fragile areas
- Barrel vaults, ridge lights and modular glass
- Daylight that reduces daytime lighting
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 Portishead
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.
See our building regulations guide for U-values, glazing limits and self-certification.
