It definitely started on underside of the aluminum sheets. In some areas the exterior surface of the aluminum looks fine, while the underside is starting to corrode.
If you look carefully at the two photos, you will notice moisture discoloration on the wood. Some of the discolored areas were under corrosion that had not penetrated all the way through. Others were under areas that had pinholes in the aluminum, but I had patched them with Eternabond tape. In other words, the cause was not the roof leaking from the top. Water was wicking in from the edges of the roof.
The sad part is that Hi-Lo did not prime or paint the underside of the aluminum. If they had I would be fixing water seepage at the edges instead of replacing the roof.
