How Far Are Roof Trusses Apart

It was perkins who pioneered roof purlins being placed on edge.

How far are roof trusses apart.

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. Putting the trusses into place. Roof trusses were usually produced on site in the past. 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.

The same concept holds true for roof trusses. 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. This is traced back to building codes and structural design standards. 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.

These standards are as follows. I ve had roof truss manufacturers try to convince me it is impossible to place wood trusses at spacings of over every 4 feet. Typical roof truss spacing means that they are usually about 24 inches from centre which means at the centre of one truss there will be a two foot gap or twenty four inch gap until the centre of the next truss. Once you ve calculated the number of trusses you will need you should purchase the lumber.
