  1. Roof Curbs for Exhaust Fans: A Complete Guide

    A roof curb might look simple, but it plays a critical role in your commercial kitchen ventilation system. If you’re installing an upblast exhaust fan, choosing the right roof curb for an exhaust fan ensures proper support, weather protection, and code compliance. Here’s a quick cheat sheet from the ventilation experts at HoodMart on how it works and how to get it right!

    What Is a Roof Curb for an Exhaust Fan?

    A roof curb for an exhaust fan is a raised, metal mounting frame installed on the roof that:

    • Supports the exhaust fan
    • Elevates the fan above the roof surface
    • Protects ductwork and fan components from weather
    • Helps meet clearance and code requirements

    Without a properly sized curb, your exhaust fan cannot be securely or safely installed.

    Do You Need a Roof Curb?

    You will need a roof curb if:

    • You’re installing an upblast (rooftop) exhaust fan
    • Your system vents through the roof
    • You need to meet NFPA and local code requirements

    You may not need a curb if:

    • You’re using a wall-mounted exhaust fan (a mounting bracket may be used instead)
