epdm or neoprene: "steel exposed fastener metal panel roof. use screws with epdm ..." - Paul M (6/9/2017) | Product Selection

steel exposed fastener metal panel roof. use screws with epdm or neoprene washers and why? If there is a clear advantage of one over the other, how should I feel about a metal roof maker that only supplies the other type? pa		Paul M 6/9/2017	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/22177/find/
I prefer the EPDM here myself in that comparison. I think they should hold up a bit better in the long term, but that is purely an opinion based on personal observations.
