Roof Trusses Distance Apart

The bay is the space within the truss and the longitudinal joining members are purlins.

Roof trusses distance apart.

The same concept holds true for roof trusses. Putting the trusses into place. A 10 8 6 and 4 spacing between trusses has been the standard for most types of construction for years. These are typically spaced at certain intervals to provide the necessary support for the roof.

Once you ve calculated the number of trusses you will need you should purchase the lumber. Also important to note here is that a two inch in a two by four or two by six is only one and a half inches in actual weight. 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. Their defense is our engineers will not allow us to.

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. This is traced back to building codes and structural design standards. In addition each roofing truss will be made of a two by four piece of lumber or in areas with expected or usual heavy snow fall there will be trusses which are two inches by six inches. 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.

I ve had roof truss manufacturers try to convince me it is impossible to place wood trusses at spacings of over every 4 feet. With traditional stick frame construction the trusses are usually spaced 2 feet 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. So the space between rafters can be greater without reducing the maximum span.
