Once you ve calculated the number of trusses you will need you should purchase the lumber.
How far are roofing trusses from each other.
Almost all residential trusses use this spacing.
Typically the contractor sets most or all of the trusses on the side of the roof opposite the location of truss number one.
Trusses decrease the possibility of material shortage delays because roof framing is supplied in one material package.
On a standard house roof trusses are 24 inches on center meaning there is a roof truss every two feet from one end of your home to the other.
Just as there are many types of roofs with many roof parts there are many different types of roof trusses.
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.
There is a little misconception about truss spacing and strength.
If the overhang is longer than about 2 feet we will need to use a 2 6 top cord or larger for the overhang depending on how long it is.
A few customers prefer installing the trusses every 16 on center because they believe this will be stronger then every 2.
The distance between trusses.

Putting the trusses into place.
Pilferage on the job site lessens because engineered trusses generally can not easily be used on other projects.
This makes the roof ready for decking or sheetrock.
To determine how far apart to set rafters measure the width of the metal panel and then the width of the first hill and valley of the panel.
The standard spacing is 2.
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.
A metal roof must also allow for some overlap on each side of the panels which will reduce the effective width of the panel.
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.
