How to safely store roof trusses onsite
The safe onsite storage of roof trusses, also known as trussed rafters, is key to ensuring the quality and maintenance of these roof components. It is also essential for health and safety, protecting anybody who accesses the site.
Delivery of roof trusses
The delivery of roof trusses should be arranged as close to the installation date as possible to minimise storage onsite. However, if longer periods of time are required, the following steps must take place:
Site storage of roof trusses
Roof trusses must be stored safely to minimise injury onsite and to prevent any damage to the trusses. Roof trusses can be stored vertically or horizontally at ground level, or, alternatively, on a secure storage platform above ground level. In either case, the roof trusses must not make direct contact with the ground or any vegetation.
They must be arranged to avoid distortion and restrained securely to avoid collapse. Roof trusses should also be protected with covers and stacked correctly to allow proper ventilation.
Storing roof trusses vertically
If you choose to store roof trusses vertically, bearers should be positioned to provide a firm and safe support with suitable props.
Storing roof trusses horizontally
If you choose to store roof trusses horizontally, level bearers should be positioned between each truss node to prevent any distortion.
Please note, no other method of storing roof trusses is suitable, except for specific provision being included in the design for an alternative temporary load case.
At Scotts Timber Engineering we ensure your roof trusses are delivered to site as close as possible to the installation date to reduce storage time on site. Safe unloading and installation guidance is provided as standard.
