What is a post typically used for in roofing construction?

In roofing construction, a post is primarily used to carry a beam. This structural element plays a crucial role in transferring loads from the roof down to the foundation by providing vertical support. Posts are typically installed in various spacing configurations depending on the design requirements of the structure and the load they need to support.

While supporting roof sheathing is important, sheathing is usually supported by rafters or trusses rather than by posts directly. Sealing roof edges involves application techniques and materials that do not involve the structural function of posts, and insulating attic space typically utilizes insulation materials rather than structural elements like posts. Thus, the significance of posts in carrying a beam distinguishes their primary purpose in roofing construction.
