I like to use scaffold and of course safety rail such that you are safe at the scaffold level. Scaffold needs to be tied off or braced to prevent toppling when ou place a ladder on to it. Even if you use a chicken ladder have a work platform underneath. the work using harness if so difficult you use all your strength just staying there. There are scaffold systems that are designed for latteral force check with your supplier. I find that working off a JLG is difficult also. </div>

<div>BTW there are at least three types of standing seam, most types can be handled using Snap-NRack hardware, but get the standing seam profile first. </div>
<div> </div>
<div>Remember you are to use every seam, to place clamps and use rails to tie the clamps to the modules. I find that this is easier than the rail-less system. </div>

<div>A ladder is not to be streched at 45 degrees. ground to roof. When tie off is used for fall protection remember swing fall and rescure plan. </div>
