Control grease around the commercial exhaust fan
Grease that escapes around an exhaust fan can stain roofing, saturate pads, collect near the curb and create maintenance concerns for the building owner. A containment review should look at the source of the discharge, the position and condition of the containment system, and the surrounding roof area.
Containment products do not replace regular fan and exhaust-system cleaning. The quote should separate cleaning, containment replacement, fan repair and roof repair so each responsibility is clear.
What is included in the service request
The final scope depends on the system, condition and safe access. The written quote should identify every included component and any limitation before work is scheduled.
- ✓Visual review of existing grease containment
- ✓Removal and replacement of saturated pads when quoted
- ✓Cleanup of accessible grease around the fan base
- ✓Review of tray, frame or containment position
- ✓Notes about damaged, missing or undersized components
- ✓Coordination with exhaust fan cleaning
- ✓Photos of visible rooftop conditions when included
What your commercial kitchen gains
Catch routine discharge
A properly placed containment system can help capture grease that escapes around the fan during normal operation.
Reduce roof staining
Timely pad replacement and cleanup can limit the spread of grease around the curb and nearby roof surface.
Separate the real problem
Containment cannot fix a leaking fan, damaged curb or neglected exhaust system. Those concerns should be identified separately.
Make recurring care easier
Add containment checks to the hood and fan cleaning schedule so saturated pads are not overlooked.

Rooftop Grease Containment FAQs
Does grease containment replace exhaust fan cleaning?
No. Containment helps manage discharge around the fan, but the fan, duct and hood still require inspection and cleaning based on the kitchen operation and applicable requirements.
How often should containment pads be replaced?
Replacement depends on grease output, fan condition, pad capacity and weather exposure. Inspect the system during regular hood and fan service.
Can rooftop grease stains be completely removed?
The amount of cleanup depends on the roofing material, age of the staining and condition of the roof. The quote should state what cleanup is included and when a roofing company is needed.
What if grease keeps escaping after new pads are installed?
The fan, curb, drain, discharge pattern and cleaning frequency may need further evaluation. A new pad alone may not correct the source.
Can containment be added during hood cleaning?
Yes. Ask for fan cleaning and containment work to be listed separately in the same proposal.
What photos should I send?
Send wide and close-up photos of the fan, containment frame, pads, roof curb and the full visible grease path.
