I am part of a homeowners association in Colorado. A person in our association is looking to use the new metal roofing that rust as siding. First what is the indistry name or a common name for this new trendy rusted roofing matterial. Second what is your oppinon of this matterial longevity and stability. Third, as a siding material it is my consern that this matterial will promote condinsation behind the walls. I do not know how it can be ventilated like a roof system can. Please send me your thoughts to my questions

They need a vapor barrier on the inside of the home to keep moisture out of the walls and some sort of housewrap on the outside. The term often used for this metal is "Corten". Its manufacturer (US Steel) does not recommend its use for architectural applications but folks do it anyway. I believe that their concerns are dealing with the run-off water and also the ultimate life expectancy of the material. Todd Miller

The proposed use of (Corten) siding will be at 10,000 feet in Colorado. In a normal winter, snow will accumulate 6 to 8 feet high agains this product (Corten). Winters at this elevation will also last for several months. How will snow and ice impact the seams and screws holding this product and how will the wall behind the (Corten) be impacted?

If you use a mechanically seamed standing seam, you should not have anything penetrate it. Otherwise, this should not be a whole lot different than a roof application. There is a product out called RainSlicker by Benjamin Obdyke Co that you may wish to use on the walls behind the metal panels. Todd Miller
