The function of Teco in a roofing system primarily involves securing roof rafters and trusses. Teco is a type of connector, often used in roof framing, that helps to stabilize the structural elements of the roof by providing critical support and alignment. By ensuring that the rafters and trusses are firmly connected, Teco components contribute to the overall integrity and durability of the roofing structure. This is vital for maintaining the roof's performance under various weather conditions and loads.

In contrast, options that imply solely decorative or aesthetic functions do not capture the structural importance that Teco connections provide. Similarly, while insulation can be critical in roofing systems to manage thermal performance, it is unrelated to the direct function of Teco connectors, which focus on structural support rather than thermal properties. Understanding the role of Teco clarifies its significance in achieving a safe and effective roofing system.
