We live in Ankeny and have a house that's just over 3 years old. Last year we had some hail and wind damage in the neighborhood. most everything got fixed. the deck is your standard deck wood, unstained and unpainted. It had some marks from the hail but no real damage, nothing that wouldn't go away with time. My wife wasn't happy about not getting it replaced even though it's structurally sound. A year later she's convinced that the screws are rusting because of either that hail or the incompetence of the builder. To me it looks more like a discoloration, like what happens to brass over time, not actual rusting but who knows. So, the question is should deck screws rust?
