Are Gutters Necessary?

Although the legal answer to this question is no, gutters are still necessary for the vast majority of homes looking to avoid long-term water damage. 

We’ll explain in greater detail in the sections below, but here are the quick bullets as to why gutters are necessary:

  • Foundation protection: By channeling water away from the base of your home, gutters are key to protecting your home’s foundation from leaks and water damage.
  • Basement protection: If you have a basement, you’ll require gutters. Without gutters, your basement is far more susceptible to leaks and flooding from stormwater that will pool around your house.
  • Roof protection: Gutters prevent water from dripping onto the overhang of your roof. Since the eaves, soffits and fascias of your roof are typically made of wood, gutters help prevent rotting and mold formation that would occur from water damage.

How Do Gutters Work?

Gutter systems consist of two parts — the actual gutters, which are responsible for catching rainwater off the edge of your roof — and the downspouts, which bring the collected water down to the ground for proper disposal. 

The gutters themselves attach to your fascia, the vertical board running under the shingles at the edge of your roof. Many systems also include downspout extenders to move the runoff to a desired and safe location on your property.

When runoff from heavy rain or melting snow makes its way down to the roof edge, the water falls into the gutter rather than down to the ground. The gutters are sloped so that the runoff travels to the corners of the property, where downspouts divert it to the ground for safer drainage away from your home.

In some cases, homeowners opt to collect rainwater from downspouts. This is an eco-friendly home improvement project that can be especially important in drought-prone areas.

What Do Gutters Do?

While the function of your gutter system is quite simple, relocating water away from your home is crucial for many reasons.

Gutters Prevent Soffit and Fascia Damage

First, gutters prevent water from dripping onto your fascia and soffits. 

Since these portions of your roof are typically made of wood, gutters help prevent rotting and mold formation, both of which can be expensive to repair and can detract from your home’s curb appeal.

Gutters Prevent Foundation Damage

Second, gutters divert water away from your home’s foundation, which is the primary reason gutters are so useful.

If water is left to fall to the ground next to your foundation, the soil can quickly become saturated. If you live in an area with clayey soil, the soil will expand in response to moisture, which adds pressure on your concrete foundation.

Over time, the expansion and contraction can lead to:

  • Cracking in your foundation
  • An increased risk of water intrusion
  • Structural damage in your home
  • Increased indoor humidity

If you live in an area with sandy soil, the runoff can cause erosion, which can leave portions of your foundation unsupported by the ground around it. This, too, can lead to instability and foundation cracks, as well as structural issues over time.

Gutters Prevent Foundation Leaks

While concrete is a strong and durable building material that’s ideal for foundations, it’s also porous. If water collects in the soil around your foundation and gets trapped against the concrete, it can soak in through the pores and evaporate into your home.

Increased moisture in your home can lead to pest infestation and mold and mildew issues. It also makes the air in your living area feel hotter in the summer and colder in the winter, which means you’ll likely drive up your energy bills as well as you call on heating and AC systems to compensate.

If you have foundation cracks from natural house settling or soil shifting, the water will also have an easier time getting in. If runoff comes in through cracks, you could be looking at actual leaks leading to water damage, destroyed building material and hazardous mold growth.

In worst-case scenarios, leaks can lead to puddles in your home or full-on basement flooding. Water leaking in can also be a fire hazard if it comes in contact with your electrical system.

In the best-case scenario, failing to install gutters can lead to manageable issues, like moisture problems in your crawlspace or basement. However, the risk of far more severe problems is high.

You could experience foundation cracks, which can be structural in nature or just cosmetic. In either case, you can expect to spend money to repair them and prevent leaking, and the most extreme foundation repairs can cost thousands of dollars.

Not having gutters on your home also means you’re more prone to pest infestations, which again, can cost you unnecessarily for pest control services.

If you have a deck or other landscaping features, runoff from a roof without gutters can also cause soil erosion and deterioration. 

If exposed to concentrated water falling from your roof, your deck sealant could wear away and begin peeling, pavers could become discolored and garden beds can get washed out.

Are Gutters Ever Optional?

Gutters aren’t always strictly necessary, and there are circumstances where you can get away without having gutters installed on your home. These include:

  • If the ground around your home is naturally protected
  • If the ground around your home is already drained properly
  • If there is a low risk of soil saturation on your property

For example, if your home naturally has a large roof overhang — 10 inches — you could probably get away without needing gutters, but only if you’re in an area that doesn’t see excessive rainfall.

If you have naturally good drainage on your property, like land sloping away from your foundation or manufactured drainage like a French drain, you might not need gutters.

Finally, if you live in an arid state — like Arizona, Nevada or parts of California — then gutters might not be a requirement.

Wrapping Up: Why Gutters Are So Important

Gutters are common not just because of their looks, but also because of how they protect your home from costly damage to your foundation. They also help protect your landscaping features, and they prevent the rotting and molding of your exterior trim, like your fascia boards and soffits.

Installing new gutters and maintaining them can be expensive, depending on the type of gutter. However, the cost pales in comparison to what you’d pay for damages caused by not having them in most cases.

There are some instances where gutters aren’t absolutely necessary — like if you live in arid states or have other drainage installed on your property — but they’re usually a good idea for most homeowners.

The best way to find out if gutters are really necessary for your home is to consult with a specialist. If you’re ready to connect with a vetted gutter provider near you, follow the link below.
