Without gutters, water has nowhere to go but down, directly to the foundation. Accumulating around this area can cause very serious problems, such as water damage, cracks, arches and possible flooding in the basement. The purpose of having gutters and downspouts is to prevent rain from spreading all over the place. Without them, heavy downpours would bathe the entire exterior of your house uncontrollably.
That's not going to end well because unrestrained water would cause soil erosion. In turn, expect damaged lawns, backyard pools, and muddy gardens. The problem starts with excess water. Without gutters, too much water comes out of the roof and falls through the house to the floor.
Over time, excess water causes problems such as fascial decay, rotting pruning, soil erosion, or foundation damage. When the materials that make up your home rot or become worn out by water, they become an easier target for animals eager to break through and settle inside. Chances are you've invested a lot of money and time in your gardening. If your water drainage system isn't properly constructed or if it's completely missing, water buildup can be disastrous for flowers and shrubs.
Overwatered gardens can detract from the curb appeal and the value of your home. If you want to prevent these six harmful effects from occurring in your home, it is absolutely necessary to have rain gutters. Those who don't have rain gutters in their house may have noticed a line running parallel to the base of their house on the ground. This is one of the main reasons why gutters exist to prevent water from damaging your home by diverting rainwater from your home.
