Standing Seam Roofs

Looking for comments on Butlers MR-24 Standing seam metal roofs. Good or bad comments welcome.

Hey Frankie,

I went to look at a repair of such a roof. It was installed over a small strip-mall.
Any way, the one i looked at was a 9-10 yrs. old, mill-finnish - no paint, and where the panels met, the locks that were crimped together began to rust.

What is the purpose of the roof you are looking at? This one is strictly commercial aplication, and is made for low pitch roofs - like a space metal bldg, etc. Bear in mind that all through-roof penetrations are dependant on sealant, and the once i saw on that mall were also rusty.
