Protect the fan and roof
Confirm safe roof access, weather conditions, fan shutdown, hinge or lifting method, wiring protection and grease-containment cleanup.
Photograph before and after
Images should cover blades, housing, duct opening, curb and surrounding roof—not only the polished hood downstairs.
Separate cleaning from repair
Loose belts, damaged wiring, failed hinges, vibration and roof damage require written follow-up and the appropriate trade.
Operations FAQ
Useful answers before the service window.
Does every fan need a hinge kit?+
Requirements depend on the system and current standard. Safe access without damaging wiring or ductwork is the objective; confirm deficiencies with the relevant professional.
Can cleaning stop roof leaks?+
No. Cleaning may reveal grease or water pathways, but roofing and mechanical defects need separate diagnosis.
