Whether you’re building a brand-new home or you’re looking to update an existing office building, having a bit of knowledge about the different types of roofing products is beneficial.

This blog will give you a brief overview of pre manufactured roof curbs and how they are an essential part of keeping you safe and comfortable in your home or office.

Roof Curbs 

Roof curbs are frames used to secure mechanical equipment such as air conditioning units, skylights, or exhaust fans to your roof. A roof curb helps support the weight of the mechanical unit and allows for contractors to gain more convenient access to the ductwork.


When an office or other building is under construction, professional contractors will install roof curbs to help accommodate the HVAC system or other roofing equipment. In order to install roof curbs, contractors must cut a hole in the roof, secure the roof curbs in place, and then place the roofing materials around the sides of the roof curb.

Once the roof curbs are installed, the supply and return ductwork for the building is connected to the curb’s openings, secured in place, and then sealed to ensure an air-tight seal.
