Trussed rafters, or roof trusses, can vary in size and weight depending on your project requirements. Therefore, this can make them unstable and a potential risk if not stored correctly.

To reduce potential injuries onsite, trussed rafters must be supported and/or restrained to prevent them toppling over. Here are a few tips on how you can safely store your trussed rafters.

  1. Store them vertically or horizontally. Trussed rafters can be safely stored in a vertical or horizontal position, at ground level, or on a temporary storage platform above ground level. If stored vertically, bearers need to be positioned to provide a firm and safe support. Alternatively, if stored horizontally bearers need to be positioned between each truss node. This is to prevent any distortion.
  2. Trusses should not make direct contact with the ground. It is important the trussed rafters are stored so they are not touching the ground or any vegetation and are arranged to prevent distortion. Also, this is to avoid timber members getting damp or damaged.
  3. Minimise storage onsite. If possible, it is highly recommended trussed rafters are not stored for long periods of time onsite and therefore, delivery should be arranged as close to the installation date as possible. Ideally, trussed rafters should be unloaded directly from the vehicle to the roof erection. However, if longer periods of storage are necessary then the trusses should be protected with covers and fixed to allow proper ventilation around them.

It is important that the above advice is followed. No other methods of storing trussed rafters are considered suitable, with the exception of where specific provision has been made in the design with an alternative temporary load case.
