How Far Are Roof Trusses 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.

How far are roof trusses apart.

Once you ve calculated the number of trusses you will need you should purchase the lumber. This is traced back to building codes and structural design standards. 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. Engineers have since determined however that the physical design of a post frame building will allow for standard spacing as great as 12 feet from the center when using high quality metal connector plates and lumber.

These standards are as follows. Roof trusses were usually produced on site in the past. 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. Most are spaced between 18 26 inches apart.

Putting the trusses into place. I ve had roof truss manufacturers try to convince me it is impossible to place wood trusses at spacings of over every 4 feet. The same concept holds true for roof trusses. With traditional stick frame construction the trusses are usually spaced 2 feet apart.
