If I remember correct, Zinc roofing does oxidize, naturally this protects it. Welding or brazing zinc is really not a good idea, and extremely poisonous. All roofing tiles, and sheets are generally bonded together with a special glue, or are rivetted. Zinc is Compatable with Stainless, Aluminum, and I think White Pine wood. Everything else corrodes the zinc quite rapidly. If it's a patch your after, then the best course of action would be the rivet an seal a fresh piece of zinc over the hole.
