200 slates were replaced. Original nails were copper. The repairers did not use hooks but non-stainless, ordinary non-galvanized iron nails hidden with coated bibs of aluminum with black vinyl or paint. What is the preferred choice of nails to prevent galvanic action? Thanks.

The type nails used to replace slates during repairs depends on the age of the roof and the expected remaining life of the existing slates, among other things. Hot-dipped galvanized nails will last 100 years, so if the expected life of the roof is less than this, such nails are suitable. If the slates are quite thick, then longer nails are required. They should also be hot dipped or copper. Having said this, however, many old slate roofs were installed with iron cut-nails, un-galvanized, and the nails have shown admirable durability *if* the slate was a hard long-lasting slate.
