Matt Risinger says that most American houses have one to four-foot overhangs but lack gutters. And although overhangs do a good job, they let the water fall on your home like an umbrella and form a dripline around. The dripline exposes pebbles around the house, and the water creates a lot of splashback, throwing dirt onto the lower part of the walls.
The situation becomes even worse if your house is made of lumber because, over time, the splashback will cause the wood to rot and open doors for all kinds of pests.
To avoid getting the outside of your house dirty or rotting the timber, gutters are of the essence.
Gutters come in different styles and sizes. For example, the US has two main kinds: K-style and half-round profile. The type you choose will depend on your roof style. After style, you can get anything from a 5 to 7-inch size. Whichever option you pick, ensure that the size of your gutters does not overwhelm your roof.
