All roof curbs are not created equal. Choose a roof curb system designed with high quality components selected to withstand severe weather conditions, and will stand the test of time.

It is important that a roof curb be designed for a specific type of roof. Roof curbs that are effective for flat built up or flat single ply roofs can be a disaster when used with standing seam metal roof panels. In fact, even when working with standing seam metal roofing, a roof curb should be designed for the manufacturer’s specific roof profile.  Choosing a roof curb specially designed for a specific metal roof profile is critical, and one curb fits all metal roofs can be a prescription for disaster. NBS roof curbs are designed specifically for our roof profiles.
