Service Process
A systematic approach to professional rooftop exhaust fan service, from rooftop access preparation through final visual inspection.
Pre-Service Rooftop Safety & Access Preparation
Our technicians conduct rooftop safety assessment and establish safe access to the exhaust fan unit. Equipment is prepared for service, and surrounding rooftop areas are protected to prevent contamination from grease runoff during cleaning.
Mechanical Scraping & Degreasing of Fan Components
Fan blades, housing interior, and accessible motor components are cleaned using mechanical scraping and commercial-grade degreasing agents. Grease buildup that affects airflow, fan balance, and fire safety is thoroughly removed.
Grease Containment System Cleaning
Grease cups, drip pans, and containment systems are emptied, cleaned, and inspected. Proper grease containment prevents rooftop contamination and supports compliance with environmental and fire safety requirements.
Visual Inspection of Fan Condition
A thorough visual inspection is performed to assess fan blade condition, belt wear (where applicable), grease accumulation levels, and any airflow obstructions. Findings are documented for your records and inspector review.
Documentation
- JSR Post-Cleaning Report
- NFPA 96 Inspection Sticker
Fan components are reassembled, and the unit is restored to operational condition. A final visual inspection confirms cleanliness and proper reassembly. Documentation is provided including before/after photos where applicable.
Why Rooftop Exhaust Fan Service Is Critical
Fire Risk Reduction
Grease accumulation on rooftop exhaust fans creates significant fire hazards. Regular cleaning removes combustible deposits from fan blades, housings, and grease containment systems.
Ventilation Performance
Grease buildup on fan blades reduces airflow efficiency and can cause fan imbalance. Clean fans operate at designed capacity, supporting proper kitchen ventilation.
NFPA 96 Compliance Support
NFPA 96 requires the entire exhaust system—including rooftop fans—to be cleaned at prescribed intervals. Service documentation supports compliance during inspections.
Extended Equipment Life
Routine cleaning and service reduces wear on fan motors, bearings, and belts. Proper maintenance extends equipment lifespan and reduces unexpected repair costs.
NFPA 96 Compliance Context
Rooftop Fans Under NFPA 96
NFPA 96 requires the entire exhaust system to be maintained, including rooftop exhaust fans. Fan blades, housings, and grease containment systems are included in the scope of required cleaning and inspection.
Role of the Authority Having Jurisdiction (AHJ)
The AHJ—typically a fire marshal or code enforcement official—may inspect rooftop exhaust fans during compliance checks. They evaluate grease accumulation, containment system condition, and service documentation.
How Proper Fan Service Supports Inspections
Documented rooftop fan cleaning demonstrates compliance with NFPA 96 requirements. Service records, before/after photos, and stickers provide verifiable evidence of maintenance during AHJ inspections.
Limitations and Documentation
Where access panels or full disassembly are not present, limitations are noted in service documentation. We provide clear records of work performed and recommendations where additional access is required.
