On the roof of nearly every multi-family and commercial building sits a row of exhaust fans, each one the endpoint of a riser serving washrooms, laundry, garbage rooms or corridors below. They run more or less continuously, in the weather, unseen — and it’s common to find one that stopped turning months ago without anyone noticing anything except a vague staleness on the floors it serves.
We clean fan wheels and housings (a loaded fan wheel moves dramatically less air), clear bird screens and curb connections, visually check belts and bearings, verify each fan actually operates, and inspect the riser connections where accessible. Everything is documented with photos — useful for councils and managers who will likely never stand on that roof themselves.
Scheduled with the systems below
Rooftop fans are the top end of the building’s exhaust paths, so it makes sense to service them alongside the systems they serve: dryer exhaust risers, bathroom exhaust ducts, and make-up air units sharing the same roof. One mobilization, one access coordination, one report.
Rooftop work is performed where access is safe and permitted, and coordinated with building management as part of scheduling.
