Managing clogged gutters and downspouts Small or insufficient gutters can cause a water overflow because they cannot handle the volume of water.
If you suspect that undersized gutters are to blame, contact a roofing or gutter professional in your area to assess the size and quantity of the gutters. As rain accumulates in the gutters, you should run towards the downspout, since the gutters are installed with a slight inclination in that direction.
