What is the primary function of headers in framing?

The primary function of headers in framing is to provide structural support above openings such as doors and windows. When an opening is created in a structure, it can weaken the wall's integrity, so headers are installed to bear the loads that the wall above would ordinarily carry. They transfer the weight from the roof and any upper floors down to the adjacent framing, ensuring that the structure remains stable and secure. This is crucial in maintaining the overall integrity of the framing and preventing sagging or other structural issues over time.

While flooring weight support and roof support are significant considerations in construction, they pertain to different framing elements such as joists and rafters, not headers. Furthermore, headers do not serve a function related to enhancing airflow in buildings; that responsibility falls to other elements such as vents and ductwork. Understanding the specific role of headers can enhance a contractor's ability to create durable structures that comply with building codes and safety standards.
