Make sure your gutters are well secured to the home and are unobstructed by debris. See photo below.

Gutters can get clogged at just about any time of the year. Of course the spring and fall are going to be the worst times for this to happen. But that is not the only time you should be aware of the gutter's ability to control water. Throughout the summer there are storms that can do major damage to the trees near your home which will send green healthy leaves into your gutters.
