Discover for yourself.

After a wet spell, call the service department at one of the heavily advertised gutter guard companies. Tell them you’re a customer with an overshoot problem. Ask how soon they can get to you. (It can be weeks.) Then tell them, “Thanks, but overshoot is a problem I don’t have to live with. I’m going with The Real Gutter Protector.”
