At my home I have a standing seam steel roof. Snow slides off better and no visible screws.....totally maintenance free.
I think the prices are comparable but standing seam is a much better option.

So because the screws are not visible (but still there) you are saying that the effects of heat and cold does not make things expand and contract? I would respectfully, argue that point...the screws through the metal, even though "hidden" are still going to expand and contract...the difference is that they are not exposed to the elements so therefore do not allow water through their elongated holes. Maybe that's what you meant...all good!
