Selecting the proper seismic roof curb isn’t simply a matter of matching dimensions—it’s about protecting life, property, and ensuring full compliance with local and national building codes. A rooftop curb that does not meet seismic requirements can put your project, your equipment, and your reputation at risk. This guide explains how seismic roof curbs are specified, what information you must gather, and how to verify your design meets all applicable standards.
Why Seismic Roof Curb Specifications Matter
It’s the responsibility of the project’s design team to ensure every component meets the safety, function, and budget requirements of a building. Rooftop curbs—often overlooked—are part of that responsibility.
Your curb’s seismic requirements may appear:
- In the mechanical schedule
- In written specifications
- In accompanying structural documents
Submitting an incorrect curb can result in costly rework, delays, or rejection during inspection.
