How we approach commercial & industrial rooflights in Leigh
For Leigh homes and buildings we offer commercial & industrial rooflights: rooflights for warehouses, schools, offices and retail units. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Exposed hillside towns in the North West need flashing and seal details that cope with wind-driven rain. In Leigh, as anywhere, commercial & industrial rooflights are the usual choice for industrial roofs with tired or fragile rooflight sheets.
Leigh is around 19 km from Manchester, and we survey and fit throughout that part of Greater Manchester, including the WN7 district.
Specification options
- Smoke and natural ventilation vents
- GRP or polycarbonate in-plane rooflight sheets
- Polycarbonate domes
- Mesh or grilles under fragile areas
- Continuous barrel-vault rooflights
- Replacement of discoloured or fragile sheets
- Fall-protection planning included
Before you order: points to check
- Fire performance of rooflight materials matters near boundaries
- Non-fragility classification should be confirmed for new products
Rules and responsibilities in Leigh
For non-domestic buildings, planning depends on the building and its location; building regulations cover thermal performance and the fire classification of rooflights near boundaries. 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. Fragile-roof safety and access are planned before work starts.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Can you replace old warehouse rooflight sheets?
Yes. We match the roof profile, replace discoloured or damaged sheets and plan safe access while the building stays in use.
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.
Can rooflights double as smoke vents?
Some units are certified smoke ventilators. See our smoke-vent rooflights page.
Do I need to be at home for the survey in Leigh?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
