Foldbak, I simply cannot imagine either of two things coming true that you have on your Christmas wish list: Keystone replacing the roof membrane because of a few staples working their way up is number one, and number two is covering the staple problem under structural problems.
I'm not saying it shouldn't be irritating, but ain't gonna happen in my opinion. I had a new Chevy 2500 in about 2009 and the camshaft wore two lobes flat at about 12K miles. Not only did they not give me a new engine (which I certainly didn't expect) but they were not going to change the oil and filter. When I insisted, it came up on my bill until the service writer calmed me down and removed it.
Don't look for a new roof.
