We get it. Chances are, you already know that gutters are important for protecting your home from water damage. Gutters keep rainwater flowing off your roof and away from your home, preventing foundation erosion, basement moisture, siding damage, landscape washout, and many other problems. So why do some homes need additional downspouts?

Downspouts are an extension of your gutter system. Simply put, downspouts carry water from your gutters down and away from your home. However, older homes sometimes don’t have enough downspouts to adequately drain the amount of water their roofs receive. Read on to learn why some homes need additional downspouts and how York County Gutters can help.

Why Do Gutters Overflow If They Aren’t Clogged?

Believe it or not, when people see their gutters overflowing during rainstorms, they automatically assume the gutters must be clogged. And while gutter clogs are certainly one of the most common reasons for overflowing gutters, insufficient downspout size can create the same issue even when your gutters are sparkling clean!

What Do Downspouts Do?

Your downspouts are where rainwater exits your gutter system. Rain flows through your gutters into a downspout, which channels water away from your home. Ideally, that water will get tossed past your home’s foundation via splash blocks, extensions, underground drains, or proper grading.

However, without sufficient downspout capacity, your gutters can overflow during heavy rainfall. Even if your gutter system is large, it won’t do its job if the water has nowhere to go!

Do Large Roofs Need More Downspouts? 

Typically, roof size is the most important factor when determining how many downspouts you need. This is because large roofs accumulate many more gallons of rainwater than their smaller counterparts. During a rainstorm, your gutters can handle thousands of gallons of water in a matter of hours.

With too few downspouts, water cannot exit the gutter quickly enough. As water builds up, your gutters can overflow even if they aren’t clogged.

Sizeable roof sections often benefit from additional downspouts.

Roof designs also play a part in drainage. Some roofs send large amounts of water into small sections of your gutter system. Roof valleys, dormers, multiple roof planes, and steep-slope roofs can all create more runoff than other areas of your roof.

During heavy rainstorms, these concentrated areas can produce more water than your downspouts can handle. By adding additional downspouts, you can spread water flow more evenly and minimize stress on your gutters.

We Can Help You Identify Roof Areas Sending Too Much Water Into Your Gutters!

Your gutters overflow when it rains. Do you notice water flowing over the sides of your gutters when it rains? Or maybe your gutters only overflow when it rains exceptionally hard. While gutter overflow is commonly caused by debris buildup, several overflow incidents may indicate that your downspouts are not large enough to handle the volume of water.

Your gutters spill over even though they’re clean. As mentioned before, many homeowners chalk up gutter overflow to gutter clogs. However, if you clean your gutters and still notice water overflowing, you may need to add a downspout.

You notice pooling or runoff near the foundation of your home. Ideally, water should be completely diverted away from your home. However, if your downspouts aren’t up to par, you might start to notice pooling water near the foundation of your home.

You see erosion around landscaping beds. Along those same lines, if there is runoff near your foundation, you may begin to see erosion around landscaping beds or any other places where water rolls through your yard.

Water stains on siding. One place you may notice excess water is on your siding. Large volumes of water exiting your downspouts may leave your home vulnerable to water staining.

Basement moisture is a common problem. We covered some of the effects overflowing gutters can have on your foundation above. However, excess water can also cause issues in your basement. By adding additional downspouts, you can keep that water where it belongs — outside!

Rain Comes Heavy in Your Area

Heavy rainstorms are no match for homes that aren’t equipped with enough downspouts. Just because your gutter system handled drainage well in the past does not mean it will continue to do so during severe storms in your area. The same is true if your home was built with only a couple of downspouts.

As weather patterns change, many homeowners are finding their current gutter systems don’t provide enough drainage coverage. Adding a couple of extra downspouts can improve your gutter system’s ability to handle large amounts of water and minimize overflow problems.

Your Gutter Sections Are Long

Another issue we see is long gutter runs. When water has to travel far distances in a gutter before reaching a downspout, overflow can occur. If you have long gutter runs, your gutters can easily get overwhelmed if all of the water is forced to drain from only one or two downspouts.

Adding an extra downspout can reduce the distance water has to travel before it is drained away from your home. Quite often, this simple modification can make all the difference in your gutter system’s drainage ability.

Downspouts Protect Your Foundation

The last thing we want to mention is why you should care about excess water around your home. Downspouts, like your gutter system as a whole, are there to protect your home’s foundation. Water that isn’t carried away from your home can pool around the perimeter. Eventually, this could lead to soil erosion, settling, basement leaks, and crawlspace moisture issues.

Any water damage near your foundation can be one of the most expensive issues to fix. Additional downspouts allow you to direct water away from these problem areas, reducing your risk of long-term issues.

Additional Downspouts Can Lengthen The Life Of Your Gutters

Your gutters work best when they can easily move water through the system. When your gutters constantly back up because your downspouts can’t handle the volume of water, it can cause extra stress to your gutters. Eventually, backup water may cause sagging or pulled-away gutters and premature gutter wear and tear.

By increasing your drainage capacity with additional downspouts, you can help improve the longevity of your gutters. A gutter system that doesn’t experience excessive stress will last longer and typically performs better.
