Roof Trusts Spacing

This is important to consider and measure exactly because if you are few millimeters out away from your actual place for truss it will put immense pressure on that truss.

Roof trusts spacing.

These are typically spaced at certain intervals to provide the necessary support for the roof. As most building these days are using those pre made trusses on the roof 24 inches become the main size for any roofing construction when it comes to its truss installation. Roof truss spacing another factor that will have its impact on truss spacing is the width of building. These standards are as follows.

The bay is the space within the truss and the longitudinal joining members are purlins. But in general it doesn t matter if the truss spacing is at 12 16 or 24 inches. Most are spaced between 18 26 inches apart. Once you ve calculated the number of trusses you will need you should purchase the lumber.

What dictates the truss design is the roof design snow load typically 20 or 30 psf in most of the u s. 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. Typical standard the typical standard for the spacing on the roof trusses is 24 inches. 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.
