This problem is everywhere - mismatching materials. From this to using nails that last 20 years in slate tiles that last 150 and more. I do not understand it. I was thinking about these since they seemed like the logical choice, my roof is very simple and not very large, plus, I thought, I could paint it white-ish. The roofer immediately brought up the point you just made about the fasteners.
