[RE-wrenches] mounting to a foam roof

[jay]

Hi All,

I have a job that the customer just told me they are going to get their roof foamed which fortunately I found out before I was installing the mounts/panels. 

It’s currently a metal roof, low pitch 5-10 degrees.  
Metal over battens over plywood.  

They want more insulation, it’s not clear how much but 4-8” probably and then probably some kind of covering on top of that, not sure what type yet.  

How are people mounting to this?  It’s only going to be 4 panels in landscape so as to keep it as low a profile as possible.  

And no mounting on the ground isn’t an option.  

thanks in advance,

jay
