Mounting system for metal sheet roof that screws in the batterns

[molle the man]

Hi, all. I have a costumer who have a new trapezoidal metal roof, in this situation I would normaly sugest a standard mounting system that only needs screws mounted in the actual metall sheet. Like renusol, novotegra, k2 and Schletter all have standard solutions for. but the costumer says i wouldent be able to sleep if the panels are not fastend in the underconstruction. To mount with stock screw/ hangebolt is not an option becouse the rafters are only 45 mm thick. I would like to have verical rails that can be screwed down in to the batterns ( witch are 60 cm apart) for horizontaly placed panels. Anyone who knows such mounting system in Europe? I am based in Sweden by the way

Is it a standing seam metal roof, or corrugated metal ?

There are special gripper clamps the clamp onto the Standing Seam (which is a very strong double thick section) of the roof, and they are certified to grip when applied properly.

Punching a hundred holes, each with the potential of a leak, into a watertight roof is a bad idea, it will void the warranty.

I had seen that article before, that snaprack solution seams to be close to what I am looking for, I emailed them to see if they have a distributor in Europe

" Is it a standing seam metal roof, or corrugated metal ?"
It is trapezodial metal sheet roof, before I have used the this rail, https://solar-distribution.baywa-re....-2-6-12-m.html witch is hollow in the middle to screw on top of the peaks of the metall sheet vertecly or horezontly. But acording to the instruction a screw that only screws down in to the metall itself should be used, so if I bring my own screw that is long enough to reach the battern I am not following the instructions and thus there is no warrenty...
