my new boss says that since we use actual plywood as opposed to osb, that we no longer need to hit studs, even for butt joints, ie; cut a 12',8',4' set and just let it end up where ever? this seems flakie to me, comment... he also nails it on w/1 1/4" inch roofing nails. i swear i heard(years ago) that w/ out a 2 3/8 nail the warranty is not valid, comment or correction?

According to James Hardie's website...you can blind nail with the 1-1/4" roofing nails. They also state that you can nail directly to OSB using 1-1/5" non-corrosive nails at 12" O.C.

Ya the whole not nailing into studs at butt joints is something that almost has to be ok, mainly because the 2 nails in both pieces only have 1 1/2" of stud to share, meaning you would have to angle you nail into it as if you're too close to the edge you'll blow the corner off. I mark and hit the studs but don't care all that much about joints.

Just use lots of nails, I use the 2" hot dipped galvi and I'm not afraid to use them... When I can't find many studs I add more nails. As Atlantic said Hardie says you can nail through sheeting as long as nails are no more than 12" OC.
