I will have a standing seam roof installed within a month and would like to know if there is any substantial difference between a mechanical seamed one (with a special crimper) and the ones with a butyl caulking that are not mechanically fastened? I wonder if the caulking will not dry out and fail in 15 or 20 years? Is this inconsequential?

In my experience, because they are shielded from the weather by the metal itself, the butyl sealants used in products such as this perform very well. Todd Miller
