Roof Deck over Standing Seam Roof?

Guest User

I'd like to replace an asphalt roof on my shallow-pitch gable coastal house with a standing seam metal roof, and then place a new wooden roof deck over part of that new metal roof (spending time on a new roof deck means we'd like a much more attractive roof around us, thus the metal roof idea). I have an architect/builder for the deck and new roof hatch access. Any opinions or ideas on how to maximize the integrity of the metal roof - how should the wooden deck be attached to it, etc? Many thanks.

Honestly, this depends upon what type of metal roof you choose. As you have seen on this website, there are countless profiles and no such thing as a "generic" metal roof> Once you find a roof you like and an experienced contractor, they should be able to make recommendations pertaining to your deck. If not, have them work with the manufacturer of the roofing to arrive at a solution. I'm sorry I cannot be of more definitive help. You will wnat to avoid direct contact between the metal and any treated lumber. There are steel and aluminum decking options you may wish to look at too.

Todd, thank you for the response. I didn't know I could actully "name names", but obviously I can. The standing seam roof roof I like best is the Follensbee Dutch Seam "Klassic Kolor" roof, if that helps you give me any additional advice about mounting a roof deck on it. I do appreciate the information that direct contact should be avoided between the metal and any treated lumber. Is that because of discoloration? Thanks!

Actually, the chemicals used in treated lumber can be very corrosive to metal. It looks to me as though, for that profile, you may want to contact a company called S5! Systems regarding their clip attachments for attaching things to standing seam roofing. I would also consult with the engineers at Follansbee. They are good people and will be glad to work with you on this.
