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?		Guest User 8/25/2005	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/6533/find/
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 Isaiah Industries, Inc. 8/25/2005	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/6534/find/
