How we approach commercial & industrial rooflights in Chester-le-Street
We handle commercial & industrial rooflights across Durham, including Chester-le-Street. In short: rooflights for warehouses, schools, offices and retail units. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Older flat-roofed extensions in the North East are often due a new roof covering — the right time to upgrade the rooflight too. Typical uses for commercial & industrial rooflights include warehouses, schools, offices and retail units.
Neighbouring towns include Washington (6 km) and Houghton-le-Spring (7 km). We offer a survey date when we reply to your enquiry.

- Non-fragility classification should be confirmed for new products
Rules and responsibilities in Chester-le-Street
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. We confirm the route for your building before ordering.
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.
