Keep fan discharge off your roof
Every exhaust fan discharges grease, and without containment it lands on the roof membrane. That is a slip hazard for anyone working up there, a code problem, and eventually a five-figure roof repair.
What a containment setup does
- Containment system fitted around the exhaust fan discharge
- Grease captured before it reaches the roof membrane
- Collection media serviced and changed on your regular cleaning schedule
- Existing rooftop grease staining assessed honestly, with photos
- Documented as part of your system's compliance record
The roof is the part of the system everyone forgets
Out of sight until the roofer, the fire marshal, or the building owner sees it. Then it is very much your problem.
Roof damage is expensive
Grease degrades roofing membranes. Replacement sections cost far more than years of containment.
It is a compliance item
NFPA 96 calls for a closed, rainproof grease collection container at rooftop terminations. Grease pooled on the roof is a violation waiting for an inspection.
Landlords care
If you lease, rooftop grease damage lands on your bill sooner or later. Containment and the photo record end that conversation.
Maintained with your cleanings
Containment media gets checked and changed on the schedule you already have with us.
Where the grease goes when nothing catches it
A fan bowl before and after. Everything that used to be in the bowl on the left was on its way to the roof.
Grease containment questions
How do I know if I have a rooftop grease problem?
Dark staining around the fan curb is the tell. We check the rooftop on every hood cleaning and will show you photos.
Does containment need maintenance?
Yes, the collection media has to be serviced regularly. We fold it into your existing cleaning schedule.
My building owner is asking about roof grease. Can you help?
This is exactly the situation containment solves, and the documentation helps with the landlord conversation.
Protect the roof before it costs you
We photograph the roof on every visit. Ask for the pictures.
