Roof Curb & Adapter FAQs

A roof curb is a raised frame installed on roof surfaces for the purpose of elevating mechanical equipment, such as an HVAC unit.

Roof curb adapters are custom-made to fit the brand and size of your new HVAC unit, when the unit does not identically match your existing roof curb. 

Installing a roof curb adapter will save you time and money because you won’t need to remove and install a new roof curb, when nothing is wrong with the one you currently use.

A fan curb is similar to a roof curb adapter, but with a simpler design. Fan curbs have only one opening in order to move air in one direction or the other.

Our roof curb adapters are custom welded to fit any size, brand, or weight of equipment.

We offer a short lead time and delivery, where your installation occurs in hours, rather than days.

It is important that your HVAC unit is not running prior to installation. We ask that you have a crane ready to remove the existing unit so the original roof curb is visible, and that you outline it with gasket material.

No. We custom design and manufacture your curb adapter to fit seamlessly into both your roof curb and HVAC unit. This allows for efficient air circulation and remains air and watertight from the outdoor elements.

When filling out our Order Form, please include the specific dimensions of your roof curb and new HVAC unit. This will ensure accuracy on your new roof curb adapter.

Yes, we offer a one year warranty on all of our roof curb products.
