Hi Troy,
I don't know what to tell you, pretty scary to me to cut a big hole in
the metal roof.
I'm curious about any links you have to those mounting systems?
thanks,

You don't screw the roofing pans down through the pan, they are all
held down with some kind of clip system; there are no roof

I'm not talking about seam clamps at all. But using a boot flashed
stand-off foot.
We looked at S-5! clamps, but they aren't rated for many types of
metal roofs. So we are going to use a Unirac stand-off foot lagged
through the pan into the roof, with a rubber boot flashing. However,
I'm concerned about the impact of fixing the roof in the middle of
the pan with the lags on the foot constraining thermal expansion
after seeing a European mounting foot system that they use a grinder
to cut a hole in the metal roof, lag to the sheathing directly and
use an overlapping rubber seal so the roof can move independently of
the mounting foot.
Has anyone had problems with thermal expansion and mounting feet
lagged through the roofing pan?
