I'm already on year 11 with my Decra stone coated metal "tile" roof. Year two with the PV array mounted above half of it. I'll certainly never install anything other than metal on either of my houses.

My PV array makes one penetration through the roof where the weatherhead I installed to run the wires comes through the peak of the roof. The 102 mounts that attach my PV array to the trusses are all installed just like they would be if I had a clay tile roof. The metal tile sheds the rain onto the next lower tile.
