Exhaust Fan Cleaning
in Fort Lee, NJ
Exhaust fan cleaning in Fort Lee, NJ involves degreasing the rooftop fan unit that pulls contaminated air out of your commercial kitchen exhaust system. The fan accumulates grease on its blades, motor housing, and the curb it mounts to every time your kitchen runs. A grease-clogged fan loses suction, strains the motor, and can fail mid-service — leaving your kitchen without ventilation when you need it most. We access the rooftop unit, degrease every surface, and check the mechanical components before leaving the site.
What Exhaust Fan Cleaning Involves
We access the rooftop fan housing safely using equipment appropriate for your building type. Fan blades and the interior of the housing are scraped and degreased. The grease collection cup or hinge-down assembly is emptied and cleaned. We inspect the motor, drive belt, and mounting hardware for signs of wear or loosening. Airflow is confirmed before we come down from the roof.

When You Need Exhaust Fan Cleaning
Matches hood cleaning schedule — monthly or quarterly. Rooftop exhaust fan cleaning should happen on the same schedule as your hood cleaning — typically monthly or quarterly depending on cooking volume. Signs that the fan needs attention before the next scheduled service: reduced draw under the hood, unusual noise from the rooftop unit, or visible grease pooling on the roof surface around the fan base. Do not wait for the next scheduled clean if those conditions appear.
Why It Matters
The exhaust fan is the engine of your ventilation system. When it cannot move enough air, grease vapor and heat back up into the kitchen instead of being expelled. That accelerates grease buildup on the hood and duct, increases fire risk between services, and can trigger fire suppression systems during a busy service. Rooftop grease pooling is also a property damage issue — pooled grease degrades most commercial roofing materials and can void the roof warranty. Poor indoor air quality from an underperforming exhaust system is a documented health concern in commercial kitchens.
NFPA 96 requires the entire exhaust system — including the rooftop fan — to be cleaned on the same schedule as the hood.
EPA indoor air quality guidelines identify grease vapor and combustion byproducts from commercial cooking equipment as significant contributors to poor kitchen air quality.
New Jersey Division of Fire Safety inspects commercial kitchens and can cite non-compliant exhaust systems regardless of whether the issue originates at the hood or the rooftop fan.

Questions About Exhaust Fan Cleaning
- Can fan cleaning be done at the same time as hood cleaning?
- Yes, and it usually is. Combining both services means one visit and one certificate covering the full exhaust system. We can also schedule standalone fan visits if the hood was recently cleaned elsewhere.
- Do you need roof access for every visit?
- Yes. We need safe access to the rooftop or exterior fan housing for every cleaning. Most Fort Lee commercial buildings have roof hatches or permanent ladders. If access is unusual, let us know when booking so we can plan accordingly.
- What happens if the fan shows mechanical wear during the inspection?
- We document what we find and inform you before leaving the site. Fan repair or replacement is outside our scope, but we will describe the issue in writing so you know what to tell a mechanical contractor.
