Roof sheeting can be started while working safely from the interior scaffold walkways. Sheeting as much as possible provides sheer strength to the trusses and provides an area to work from once it is necessarily to get on the roof to finish the sheeting process.
The worker is protected from the fall hazard before getting onto the roof by attaching to the lifeline that was connected when the truss was rolled into place. As the sheet is handed up to the worker on the roof, the sheet is kept in front of him as a barrier to provide protection from the opening between the trusses. Once the sheet is in place, the sheet can be tacked or nailed to prevent movement. This safe work process minimizes fall exposures to the inside.
Once enough of the roof has been sheeted to allow an additional worker to tie off, a second worker can safely access the roof. One worker can safely place and tack sheets while the other completes the nailing. The stair stepping of sheeting should eliminate any fall exposure to the inside for the second worker.
Because of the different types of roofs pitches and styles, proper anchorages and fall protection are essential to protect workers from falls. There are a number of manufacturers of fall protection equipment. Your choice of fall protection equipment is quite extensive. Be sure to use the appropriate equipment for each job. Whatever equipment you use always refer to the manufacturer's instructions for installation and proper use.
