sheathing under metal roofing: "I am building a porch and want a metal roof ..." - Guest User (6/8/2007) | General Discussion | Archive

I am building a porch and want a metal roof on it. I was wondering about the sheathing under the metal. Should I just use OSB with felt over it? Or could I use high density foam with felt and then strap the roof and install the metal over it? Or what about high density foam then OSB felt and then metal. Would strapping over the OSB be required if I just used OSB?		Guest User 6/8/2007	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/9669/find/
Most products do not require strapping. Some products may have some limitation in their ability to be installed over foam, or over strapping. You need to choose a product and then work with the manufacturer of that product to determine correct installation.
