Roof trusses should be secured to the wall primarily using metal tie down straps because these straps are specifically designed to provide strong connections that help resist lateral forces, such as those from wind. This is particularly important in areas susceptible to hurricanes or severe weather, where the structural integrity of the roof is critical.

Metal tie down straps enhance the overall stability of the roof system by securing the trusses to the top plate of the wall framing. This method helps distribute the load more evenly and provides resistance against uplift forces. Additionally, the use of metal straps contributes to the longevity of the connection, as they are less prone to damage from moisture and other environmental factors compared to nails.

While the other options, such as using nails as methods of securing roof trusses, may also provide some degree of fastening, they do not offer the same level of structural support as metal straps. In practice, metal tie downs are often the preferred method for ensuring strong and resilient connections in roofing applications. Their widespread usage is supported by building codes and best practices in construction.
