How Far Apart Are Roof Trusses Normally Placed

Once you ve calculated the number of trusses you will need you should purchase the lumber.

How far apart are roof trusses normally placed.

A 10 8 6 and 4 spacing between trusses has been the standard for most types of construction for years. The same concept holds true for roof trusses. The trusses should be a little longer than the exact width to allow for overhang and you will need sufficient trusses to mount across the length. For many traditional stick frame builders trusses spaced 8 feet apart seems unnatural but thanks to the ingenuity of modern engineering it is a very common building design.

Putting the trusses into place. The bay is the space within the truss and the longitudinal joining members are purlins. These are typically spaced at certain intervals to provide the necessary support for the roof. This is traced back to building codes and structural design standards.

Their defense is our engineers will not allow us to. Common spacing for trusses on this type of building is often between 2 and 4 feet but trusses built with advanced designs may allow spacing as great as 8 or 12 feet. With traditional stick frame construction the trusses are usually spaced 2 feet apart. With this design change roof trusses could be placed 12 feet apart making it possible for roofs to support the loads to which they would be subjected.

Most are spaced between 18 26 inches apart.
