I installed perforated z closures many years ago. I crammed pieces paper towel behind a few z closures in a few high wind areas (2 1/2” in 12 pitch). I am able to access them from the attic. After numerous windy storms I inspected for moisture. Never the slightest evidence of water.
Check out the layover hip and ridge detail @ 6:47/11:10 Wow nice job to whom ever put that together. layover double locked valleys as well. Looks great !!!!!!!!!
These guys never put a roof in their life. These conversations need to be had with real roofers who have actual knowledge on what works and what doesn’t
What keeps the exposed fastener screw from backing out due to thermal movement of the two pieces of metal? Seems to me like greater danger of your ridge cap eventually blowing off.
Our supplier sent us foam closures and is saying to screw the ridge cap on top of the standing seam which is a snap system and the female end has a width of maybe 3/16 and isn’t flat. This can’t be the right way to do this especially when we get hurricane force winds of over 110 mph with rain or snow. The ridge is not vented is there another way to do this?

I drill my own z closers, We use tile flash one way venting to keep it water tight.

Wow these guys are definitely sales people and not actual installers....I don't know that I have ever seen a worse system than that
