What do commercial & industrial rooflights involve?
Our commercial & industrial rooflights service in Cheshire covers rooflights for warehouses, schools, offices and retail units. We survey every job before fixing the price.
Stone and brick terraces are typical across the North West, and roof windows in rear slopes are a common way to light attic rooms. Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed.

Planning and building rules in England
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. Fragile-roof safety and access are planned before work starts.

- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.
