Pros and cons of a power seal installation: "We are in the process of installing a metal roof. ..." - Denise DiGennaro (3/6/2015) | I Have An Existing Metal Roof and Have A Question | Ask The Experts Forum

We are in the process of installing a metal roof. The men installing the roof are telling us that it is not necessary to use the power seal procedure on the seams of the roof, that it will make the seams crooked, and that in the event of a storm, a regular seal will be fine, and that the regular seal will save us a few thousand of dollars. Does anyone know if this is true, and if so why, and if not why. Thank you. They will be completing the roof on Monday and Tuesday, so a prompt answer would be appreciated. Today is Friday March 6th, 2015.	Denise DiGennaro 3/6/2015	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/20186/find/
Are you referring to the difference between a mechanical (double) lock and a clip lock? Both are quite good. They are really application specific but if the panel is made or formed for a clip lock, it should be installed as such.

Like Eric said ... the panels that need to be crimped and the panels that don't need to be crimped are not the same. It has to be one or the other. If you wish, send me a picture of what has been installed.
