The Need for Roof Curbs for Exhaust Fans

by | Mar 17, 2023 | Roofing

If you are in the process of installing a new roof on your commercial building, it is important to ensure that roof curbs are installed for all of your exhaust fans. A roof curb is a metal frame that is installed around the perimeter of an exhaust fan, and it helps to provide support and stability for the fan.

In addition, roof curbs for exhaust fans help to seal the area around the fan so that air and moisture cannot enter the building through the fan.

Why You Need Roof Curbs for Exhaust Fans

There are several reasons why you need the best roof curbs for exhaust fans in your commercial building. First, exhaust fans can be weighty, and without proper support, they can cause the roof to collapse.

Second, exhaust fans must be properly sealed to prevent air and moisture from entering the building. If there is not a proper seal around the fan, you run the risk of mold and mildew growing inside your building.

Third, exhaust fans must be able to withstand high winds. If an exhaust fan is not properly secured, it can be blown off of the roof during a storm, which can cause serious damage to the building.

Installing Roof Curbs

Installing roof curbs for metal roofs is not a do-it-yourself project. It should be done by a professional who has experience installing roofing systems. In addition, you will need to have the proper permits in order to install roof curbs on your commercial building.

Once you have obtained the necessary permits, you will need to hire a contractor who specializes in installing metal roofs. The contractor will measure the area around each exhaust fan and custom-fabricate each metal frame to fit snugly around each fan.
