For roofing installations, or walling installations not on the ground level, on large building projects you can reduce handling time by lifting bundles with a crane direct from the delivery truck onto the roof frame. Use a spreader bar for long sheets. For small to medium size projects, without mechanical handling facilities, you can unload sheets by hand and pass them up to the roof one at a time.
It is recommended that heavy-duty cut-resistant gloves and appropriate manual handling techniques or a lifting plan be used when handling material.
Handle materials carefully to avoid damage: don’t drag materials over rough surfaces or each other; carry tools, don’t drag them; protect from swarf.
