What to Know About Roof Curb Installations

For commercial buildings, a roof is much more than just a protective covering. Large industrial and commercial roofs need to do more than provide a ceiling; they also must support heavy equipment that is critical to the function of the building. To handle this extra hardware, many commercial roofs should have one or several roof curbs.

What Is a Roof Curb?

A roof curb is an elevated platform on a roof that supports some piece of equipment or roof penetration. Because roof curbs are sometimes a part of a roof, they must be able to keep out moisture and debris, while providing a spot to anchor the equipment.

Most commercial buildings will require some type of roof curb. They are used with everything from exhaust fans and HVAC units to skylights and vents. Each type of equipment requires a different kind of curb, and each type of roof material carries different considerations.

Who Can Install a Roof Curb?

Installing rooftop equipment and roof curbs typically involves more specialists than other aspects of a building’s construction. The general contractor and the equipment manufacturer will likely do a great deal of the work, but to get the job done right, it’s also important to bring in a professional roofer. 

While other specialists may be more familiar with the product going on the roof, only a qualified roofer can ensure that the roof itself will still function as needed once the equipment is installed. Maintaining a weatherproof roofing surface is critical to the health and longevity of any commercial building.

Other Things to Consider with Roof Curb Installation

Some of the most common problems with roof curb installation occur when rooftop equipment is replaced. Rather than call a professional roofer, many facility managers will simply have the contractor use an after-market roof curb. While going this route may save some money up-front, after-market roof curbs can often create airflow and temperature issues once installed. 

To ensure the continued safety and functionality of the roof, it’s best to use a fully-welded and assembled custom roof curb. Though this may cost more money up front, a custom roof curb improves longevity and protects the investment in the roof and the roof-top equipment. Finding a roofer with its own fabrication department is the most cost-effective way to get a quality product.
