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.
How far apart are roof trusses normally placed.
I ve had roof truss manufacturers try to convince me it is impossible to place wood trusses at spacings of over every 4 feet.
Most are spaced between 18 26 inches apart.
Their defense is our engineers will not allow us to.
These standards are as follows.
Putting the trusses into place.
The bay is the space within the truss and the longitudinal joining members are purlins.
The same concept holds true for roof trusses.
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.
A 10 8 6 and 4 spacing between trusses has been the standard for most types of construction for years.
Once you ve calculated the number of trusses you will need you should purchase the lumber.
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.
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.
These are typically spaced at certain intervals to provide the necessary support for the roof.
