OSB decking

I'm building a new addition to my house. My plan is to place 26 ga PBR panel on the roof over 7/16" OSB decking. Going to use a synthetic underlayment on top of the decking, between the decking and metal panels. I keep hearing horror stories about the screws used to attach the metal panels not holding in 7/16" OSB....eventually backing out. Ever heard of this issue? Is 7/16" OSB thick enough or should I go thicker? Maybe 1 X 4 or 2 X 4 furring? Looking for suggestions and input.

Screws do hold in OSB. Some folks think that the holding power of nails is OSB is questionable, but I see no issues with screws.		Eric Novotny An informed customer is the Best Customer! 10/15/2015	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/20745/find/
Sounds good. Thanks for the reply.		Guest User 10/15/2015	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/20746/find/
I plan on doing this as well. I've read that since I'm going to be using 7/16 OSB I need to use #14 screws. My question is, what length screws to use? The shortest I've found are 1" and would then penetrate all the way through the sheathing. Is that correct?

That is completely fine in that case. I prefer Plywood to be honest if you can use that instead, but either will work.		Eric Novotny An informed customer is the Best Customer! 8/21/2017	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/20748/find/
