screws

Are the screws put in the groove or the ridge and what are the benifits?		dan miller 7/20/2011	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/16159/find/
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 Isaiah Industries, Inc. 7/20/2011	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/16160/find/
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 An informed customer is the Best Customer! 7/22/2011	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/16161/find/
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.
