Are the screws put in the groove or the ridge and what are the benifits?

In all cases you should follow manufacturer instructions. Most manufacturers seem to suggest they go on top of the ribs or in the wide flats of the panels. Again, though, always follow manufacturer instructions. Todd Miller

Definitely check with you panel manufacturer for the final decision, however, the groove is water pathway and should be avoided as fastener location. Eric Novotny

I have followed this question for quite a while, before I had a metal roof installed. The practice in N America and Europe is in the flats, but in New Zealand and Australia they will install in the ridges. If you check the New Zealand metal roofing code of practice they discourage flat installation of screws, and prohibit it in long panels, as the expansion of the metal will loosen the screws.
