How we approach commercial & industrial rooflights in Denton
Our commercial & industrial rooflights service in Denton 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.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. Commercial & industrial rooflights suit warehouses, schools, offices and retail units.
From Denton to Hyde, Dukinfield and Droylsden, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Continuous barrel-vault rooflights
- Mesh or grilles under fragile areas
- Smoke and natural ventilation vents
- Polycarbonate domes
- GRP or polycarbonate in-plane rooflight sheets
- Barrel vaults, ridge lights and modular glass
- Planned around working sites
What to check first
- 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 Denton
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. 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.

Questions about commercial & industrial rooflights in Denton
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 work out of hours?
For occupied buildings we can plan phased or out-of-hours working where access allows.
How do I book a survey in Denton?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Denton?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
