Most restaurant exhaust systems end in an upblast fan on the roof. It is out of sight, so it is often the dirtiest part of the system. Grease builds on the fan wheel, overflows the drain, and soaks into roofing material around the curb.
We open, clean, and rinse rooftop fans, clean the curb and surrounding area, and report the condition of containment, hinges, and visible fan components.
What this service covers
- Upblast fan wheel and housing
- Fan curb
- Grease drain spout

- Roof membrane stained or softened by grease

Safety and NFPA 96
For rooftop exhaust fan 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.
