Bumpy Plywood – Will It Cause Issue For Metal Roof – GreenBuildingAdvisor

I’m working on a roofing project where I’ll be putting in a new deck with 19/32 plywood. This particular plywood pictured is Plytanium brand that I purchased from Lowes. I bought about 30 sheets of this all from a brand new pallet they brought from out back. Because it was only 10 minutes to closing time when I pulled these I rushed somewhat and with the lighting in the store did not notice the surface finish and bumpiness.

I’m putting a 26ga standing seam metal roof over the top of this (black color), with a peel and stick membrane under it. I’m worried that because of the black color that this bumpiness could show thru in places on the metal roof panels. I’m planning on taking it back to Lowes to exchange for sheets without bumps. As regular wall sheathing or under a shingle roof I don’t think this would matter, but in my case I’m hesitant to use this.

Anyone else ever seen sheets bumpy like this before? I searched the internet and couldn’t find anything like this anywhere. I don’t know what would cause this other than some manufacturing issue as I’ve handled a fair amount of plywood in my life and I’ve never seen this before.
