How we approach commercial & industrial rooflights in Runcorn
We handle commercial & industrial rooflights across Cheshire, including Runcorn. In short: rooflights for warehouses, schools, offices and retail units. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. In Runcorn, as anywhere, commercial & industrial rooflights are the usual choice for industrial roofs with tired or fragile rooflight sheets.
Runcorn is around 12 km from Warrington, and we survey and fit throughout that part of Cheshire, including the WA7 district.
Options we can specify in Runcorn
- GRP or polycarbonate in-plane rooflight sheets
- Mesh or grilles under fragile areas
- Continuous barrel-vault rooflights
- Polycarbonate domes
- Modular glass rooflights
- Daylight that reduces daytime lighting
- Fall-protection planning included
Things we check at survey
- Fire performance of rooflight materials matters near boundaries
- Fragile rooflights are a known fall hazard — work at height must be planned
Rules and responsibilities in Runcorn
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.

Common questions
Can rooflights double as smoke vents?
Some units are certified smoke ventilators. See our smoke-vent rooflights page.
Are old rooflights a safety risk?
Older plastic rooflight sheets can become brittle. Anyone working on the roof must treat them as fragile unless proven otherwise.
Do you supply O&M information?
Yes — product data, manufacturer warranties and maintenance notes are handed over at completion.
Can you work alongside my builder in Runcorn?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Runcorn?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
