Gutter Downspout Basics
Your home’s gutter is the channel that’s installed near the roofline of your home, where the roof slopes downward. This drainage system is usually made from aluminum, vinyl, stainless steel, or copper. Gutter systems are set at a minor downward pitch toward the corners of your home. This design encourages the flow of water or snowmelt to flow downhill, where it eventually reaches the downspouts.
The downspouts are the pipes that run vertically along the side of your house. It connects near the top of the gutter channel through a hole, but the other end bends away from the home and sits several inches above the ground. This system permits water to flow away from your home and landscaping before exiting the pipe.
How Many Downspouts are Required?
The general rule of thumb that most gutter professionals follow is that there should be one downspout per 20 feet of the gutter system. However, depending on the size of your home and the local weather, you may need more gutter downspouts.
Gutters and downspouts that are poorly designed and installed can lead to water runoff pooling near the base of your home. Even worse, it can cause the water to back up into your gutters, which can lead to serious damage to your home’s exterior and interior.
Gutter & Downspout Maintenance
Homeowners should aim to have their gutters and downspouts cleaned and inspected at least two times per year. However, the truth is that gutter cleaning may be required up to six times per year, depending on where you live.
Getting on a good gutter cleaning schedule will help you locate drainage issues and leaks before they turn into costly problems. In general, if you need to repair cracks or leaks in gutters, simply use a bit of sealant or caulk. However, if you have drainage problems, installing splash blocks or downspout extensions can help.
The key to keeping your home’s gutters and downspouts in good shape year-round is to have a good gutter maintenance program in place.
