Everything the NFPA-96 standard touches — from the hood you see to the rooftop fan you don't. Every service is delivered by a vetted, insured network crew.
The core NFPA-96 job: stripping cooked-on grease from the hood, filters, and the full exhaust duct run up to the rooftop fan — bare-metal clean, not a wipe-down.
The rooftop fan is where grease collects and airflow dies. Cleaning the fan blades, housing, and belt keeps your hood actually pulling smoke — and keeps grease off your roof.
Grease on a roof voids warranties and starts fires. Containment systems catch fan discharge before it spreads — and most landlords and insurers now expect them.
NFPA-96 requires the whole duct to be cleanable. Where a run has no access, code-compliant panels are cut in so the duct can actually be reached and certified.
Not sure where you stand? A system inspection tells you your real cleaning interval and whether your hood, duct, and fan meet code — with paperwork your fire and health inspectors will accept.
