Installation considerations
We check roof pitch and covering, the kerb or upstand, opening angle and access.
Every installation starts with a free survey. We confirm the specification, give you a written quote, install and commission the system, and hand over with test records and instructions.

Maintenance of roof smoke vents
Planned maintenance keeps roof smoke vents safe and reliable and gives you records for insurers and inspections. We service Ventlux and all other makes: we check fixings, wear, power and battery backup, controls and safety devices, adjust and lubricate where needed, test operation end to end and leave a written report with any recommended actions.
Repairs
If your roof smoke vents has stopped working, is noisy, is opening or closing on its own or is showing a fault, we fault-find on site and repair it, often on the first visit using parts from our shop. We repair systems we did not install and work on all common makes.

Servicing intervals depend on use and risk; most sites have a service at least once a year, busy or safety-critical systems more often. We can set up a service contract with reminders so it is never missed. Installation, maintenance, repair and service prices are POA after a free survey and quote.
