Though many houses have gutters, it can be tough to tell what role they play in maintaining your home’s exterior. You may even find yourself wondering if gutters are necessary. A gutter system directs water away from your home, helping prevent mold, mildew, dangerous water buildup and other water damage around your home’s foundation over time.
Our team has conducted in-depth research to understand the ins and outs of rain gutter systems and determine the best gutter guard companies. This guide explains what makes gutters necessary and how you can optimize your home’s gutter system for maximum safety and stability.
How Gutters Work
Gutters hang off your roof and catch rainwater as it streams down the surface. Your gutter system then channels that water toward the edges of your roof and into vertical sectionals called downspouts. Downspouts direct water away from the home into a storage receptacle (such as a tank or barrel), into an irrigation system, or onto a plastic tray (called a splash block) that disperses it on your lawn.
When Are Gutters Necessary?
Gutters are not required by law in most states, nor are they required in the majority of building codes. However, gutters are an important part of your home’s drainage system. Gutters direct water away from the home, protecting essential structures from water damage, erosion, mold, and other expensive problems.
Gutters provide protection to the following parts of your home:
- Foundation: Without a gutter system, water will pool around the base of your home. Over time, this soil saturation can cause serious problems such as shifting, cracks, erosion, and flooding in your basement or crawl space.
- Lawn: When water pools around your home, it affects more than just the foundation. The soil itself can become badly damaged. Pooling water can lead to increased pest activity (such as mosquitoes, lawn grubs, and termites), root rot, dead grass, mold growth, and soil erosion.
- Walls: Gutters prevent water from pouring down your walls. This system keeps your siding, internal walls, window and door frames, and utility entry points free of flowing water.
While most homes will benefit from gutters, some require them more than others. For example, homeowners in regions with frequent rainfall, such as the Pacific Northwest, should invest in gutters. Homes that experience downpours would also benefit from wider gutters to handle the increased rainfall. Here are some situations in which gutters are essential to keep your home in working order:
- Upward slopes: You’ll want a gutter system if your home sits at the bottom of a hill or other upward slope. Without one, rainwater from these slopes could build up around your home’s foundation rather than moving away from it.
- Clay-rich soil: You should invest in rain gutters if your home is near a lot of clay-rich soil. Clay-rich soil absorbs, disperses, and drains water more slowly. Because of this, soils with high concentrations of clay can be prone to standing water or heavy saturation issues. Gutters help prevent this by dispersing water more evenly throughout your lawn or draining it into a tank or underground basin.
- Basement foundation: Without gutters, water can enter your home and cause basement flooding. This could be especially bad if you have a finished basement, as there could be water damage to your belongings that could be easily avoided with a simple gutter installation.
- Little to no overhang: If your roof’s overhang fits close to your home’s siding, frequent rain will cause trenches to form where the water builds up. Often, that rainwater remains close to the foundation once it’s absorbed into the ground, causing severe and costly damage over time. Without gutters, you may also experience water damage to your siding.
When Are Gutters Optional?
Though gutters are usually required or highly encouraged, there are some situations in which gutters are optional. We’ve listed them below.
- Climate: A dry, arid climate means less rainwater and puddling. Therefore, homes in regions with a drier climate do not require gutters as much as homes in wetter climates.
- Downward slopes: If your home sits on top of a hill, you may have to worry less about gutters. Water is more likely to naturally move away from your home if your landscaping and property feature a lot of downward slopes that point away from your home.
- Long overhang: If your home’s overhang is between six to 10 inches long, you may be able to avoid installing a gutter system depending on other factors, such as landscaping and your local climate.
Gutter Problems and Solutions
Though gutters help you prevent significant homeowner headaches and problems, they can also create a few problems. However, these can easily be avoided and addressed. Read over the most common gutter problems and their solutions below.
- Clogging: Because gutters feature large openings, debris like leaves, twigs, pine needles, shingle grit, and pollen can build up over time. Birds and other animals can also build nests inside your gutters. These issues cause water clogs and water damage. However, you can combat this problem with routine cleaning and maintenance or investing in a gutter guard system.
- Ice dams: Many people believe gutters cause ice dams, but this is actually because of your roof and attic. When the snow melts and gets into the eaves of a sloped roof, it can freeze there. This results in an ice dam, or a buildup of ice. Because gutters are next to your eaves, it appears that your gutters are causing the ice dam. Like clogs, routine maintenance of your attic’s ventilation and insulation helps you avoid this issue. Gutter guards with heating elements can also help you combat ice dams.
How To Improve Gutters
You can improve your gutters by adding additional structures or installing new gutters made from higher-quality materials. Additional structures can include the following:
- Drainage systems such as French drains, rain chains, and underground water storage tanks
- Gutter guard system
- Irrigation hookups
- Rain collection systems
- Splash blocks
If you want to improve your gutter system by upgrading its materials, you must remove your old gutters and install new ones. The installation cost for your new system will depend on the material you choose and the total linear feet of guttering you need.
Vinyl and aluminum are the most common materials, which can cost between $1,700 and $2,400 for materials and labor. Higher-end materials, such as steel or copper, can range from $2,800 to $9,400.

How To Maintain Gutters
Gutter maintenance requires numerous tools, such as gloves, a ladder, a gutter scoop, an electric drill, and a stabilizer. You need to be experienced and comfortable working on ladders or roofs. If you don’t have the right tools or skills, we recommend hiring a professional gutter company.
Gutters are necessary in most cases. However, if you want to know whether or not your new construction or home improvement project requires gutters, consider the property’s landscaping features, the climate, the overhang, and the foundation type. If you find that you do need gutters, we recommend that you get at least three quotes from three gutter installers to compare pricing and offerings.
We also encourage you to consider investing in a gutter guard system. Gutter guards block debris from entering your gutters and push it out. Then, you can rake up the fallen debris or knock off standing debris with a broom. We have listed some of our top gutter guard recommendations below.
