Our Roof Exhaust Fan Services in Long Island City
Emergency and scheduled repair for roof-mounted exhaust fans — restoring code-compliant airflow across LIC's commercial buildings.
Emergency Roof Fan Repair
A seized or failed roof exhaust fan traps heat, humidity, or odor inside your building fast. Certified technicians reach LIC sites typically within 4 hours.
Belt, Bearing & Motor Replacement
The most common causes of roof fan failure repaired with same-day parts in most cases, restoring rated airflow rather than a temporary patch.
Curb & Flashing Repair
A fan can run fine while its curb or flashing leaks. We inspect and repair mounting hardware and roof penetrations to stop water intrusion at the source.
Control & Interlock Repair
Roof fans are often interlocked with exhaust or makeup air systems. We diagnose and repair controls faults that throw the whole system out of balance.
Seasonal Fan Maintenance
Scheduled inspections ahead of LIC's high-demand seasons catch worn belts and failing bearings before they become an emergency call.
Airflow Verification & Reporting
Post-repair testing confirms your roof exhaust fan is delivering the airflow your space requires by code, with a documented report on file.
