Compatibility of Zinc and Galvanized Steel Roofing | Ask The Experts Forum

Guest User 10/21/2014	Is it safe for zinc roofing to drain onto a standing seam roof made from G90 steel painted panels? The fact that the steel is coated with zinc suggests that there should be no problem, but subtle effects sometimes arise. Any corrosion risk for the zinc or the G90 panels?

David Stermer 10/22/2014	Hi Fred, Thanks for your question about metal roofing. Zinc roofing and galvanized roofing are compatible. There is minimal potential for problems when zinc and galvanized steel are in contact or water runs from one onto the other.
