Rooftop grease containment collects grease that drains from the exhaust fan. When containment units fill up or are missing entirely, grease spreads across the roof, damaging membranes and creating a slick, flammable surface.
We clean the area around the fan curb and service accessible containment units during exhaust cleaning, and we note when containment is full, damaged, or absent.
What this service covers
- Grease boxes and absorbent containment
- Fan drain spouts
- Curb and surrounding roof area
Common problems we address
- Overflowing grease boxes
- Stained or blistered roofing
- Grease runoff toward drains
Safety and NFPA 96
For rooftop grease containment cleaning, NFPA 96 (the National Fire Protection Association standard for commercial cooking operations) is the usual reference for inspection, cleaning access, and documentation. The edition in force and how it is enforced depend on your local authority having jurisdiction. We clean thoroughly and document our work, but no contractor can guarantee an inspection result. Learn more about NFPA 96.
