Unless you have no other way to get water away from your house, IMO, gutters are nothing but a pain. In any state. On any house. They clog in the winter with ice, they clog in the fall with leaves, you have to clean them every year, longer spouts at the bottom get knocked about. Eventually they start to fall apart, especially if you don't clean them and maintain the woodwork on which they're mounted.

Grade your land accordingly or install drainage around the house. Life is better without gutters.
