Rainwater accumulates on your house's roof and runs down into your gutters, which are supposed to collect and drain it away from your home's foundation. Downspouts can be seen as an accessory that helps your gutters drain water as far away from your foundation as possible. Downspouts are channels or pipes that are connected to gutters and installed along the sides of your house to redirect rainwater and safely lead it to a drainage area. Draining water away from your home’s foundation decreases your chances of developing cracks and shifts due to water damage.
