In this regard, do galvanized nails rust?
Galvanized steel nails will eventually rust (use stainless steel nails to completely prevent rust), but the galvanization (zinc coat) will prolong the nail's lifespan - as compared to non-coated alternatives.
Subsequently, question is, how do I stop my nails from rusting? Before you begin the paint job, caulk each nail with a water-based acrylic caulk. This should before any priming or painting is done. A rust inhibitive primer can be applied to both the surface and the nails before the paint job begins. The primer contains materials that counter the nail's capacity to develop rust.
Thereof, what kind of nails should be used for roofing?
Stainless steel nails are also good for fastening tiles and slate, or you can work with copper nails for standard roofing purposes. Galvanized roofing nails are steel nails that are zinc-coated. They hold up better against rust, and they can also be used for asphalt shingles.
Do roof sheathing nails need to be galvanized?
Assuming you are hand nailing, the APA suggests 6d for =/< 1/2" wall sheathing and 8d for roof sheathing. 6" OC on panel edges and 12" in the field. I'd recommend hot dipped galvanized. Your roll roofing should be applied with hot dipped galvanized nails, 1" long (electro-galvanized is fine if using a roofing gun).
