I am specifying a cor-ten 2.67 x 1/2 corrugated panel system for a residence at alt. 8400 ft. in a snow load area. I am using a compatible Grace products ice and water shield underlayment. I am obtaining the product through Corrugated Metals Inc. They have recomended that I contact you as a reliable source. Iam looking for architectural details and installation methods; specifically, rake flashing, edge metal, ridge cap, hip cap, valley metal and fastening methods. As the profile is quite common I am hoping source information for corrugated installations is universal. Does a source reference for your industry exist similar to the reference manual Archetectural standards and Details for the design industry.

I guess we should be flatterer that we are now considered an industry resourse. I would be firstly concerned in buying a product from a manufacturer that does not have installatio instructions. This is even more important with Corten as it will drip red rust in moist anvironments. It relys on the oxidation to protect itself. If the oxidation layer is removed it will oxidize again. Use in snow country is one of the worst environments that it can be used in and not recommended. Having said all that I would contact the Wheeling Corrigated comapny and let them know we recommended that you contact them.

I agree with Al's reply. Ultimately, you want to make sure that you are adhering to the installation instructions put forth by whoever fabricates the roofing. However, I will also let you in on a resource I use for flashing details ... www.mtlsales.com They have flashing details for many of their profiles available online in .pdf format.

Al, Could you list out some of the reasons why you are indicating that a snow environment is one of the worst environments in which to use Cor-ten metal roofing? Does roof slope make any difference?	Guest User 2/4/2003	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/1221/find/
I sit on many industry committes with representatives of US Steel who have made Cortan and they are currently serving notice on their web site not to do it. Anyways Cortan relies on the oxidising of the surface to protect itself. This works great in AZ however when the snow and ice get on it it removes the oxsidation and then the steel starts to rust all over again. Meanwhile the runoff stains the fascia, siding and sidewalks not to mention killing some plants. They look good and perform well in the dessert, but not in a lot of the other areas. Hope you understand.	Allan Reid Dura-Loc Roofing Systems, Inc. 2/6/2003	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/1222/find/
