Guide to Gutter Splash Guards

By Britt Olizarowicz

A gutter splash guard is something you have likely seen installed on gutter systems in your area. As effective as gutters can be, there are times that gutter splash guards are necessary. In our gutter splash guards guide, we show you:

  • What gutter splash guards are
  • Who has the best gutter splash guards
  • How to tell if you need gutter splash guards

If you already have a gutter system in your home, a good portion of the work is done. The splash guards will help ensure that your gutter system is functioning to the best of its ability.

What are Gutter Splash Guards

Gutter splash guards are pieces of material attached to an existing gutter system that helps prevent overspilling. Many homeowners don’t realize that gutter systems on a home can be a bit like a road map. When water is pushed to one area of the roof, you will have issues with spillage. This typically happens in roof valleys.

The gutter valley splash guards stick up over the top of the gutter, and they push water back into the gutter as opposed to down to the ground. At the time of Gutter installation, your gutters should be checked to see if they will benefit from a diverter or splash guard to prevent gutter overflow.

However, over time and when the gutters are tested with a true heavy rainfall, you may notice areas where a gutter splash guard is necessary. It can then be installed after the fact. When gutter splash guards are added to the home, sometimes it’s worth looking into the best gutter guards as well. Here are a few ways to tell your current gutter system needs some attention.

Signs You Need Gutter Splash Guards

Splash guards on your rain gutter are mostly necessary in the corners and valleys; however, this is not always the case. Some homeowners have a steep pitch in their roof, and it requires an extra splash guard. Here are a few of the most common reasons to install splash guards on your gutter.

Overflowing Gutters

The most telling sign that gutter splash guards are necessary is overflowing gutters. If water pours over the gutter’s side, chances are the gutter system needs some attention. Overflowing gutters could lead to you having to install a leaf guard, a downspout diverter, or even gutter downspout extensions; however, gutters should not be overflowing.

Take a look at the corners of the gutter system; this is where you tend to see the most trouble with overshoots. The inside corner especially is an area where water tends to flow fast and make runoff more apparent.

Roof Leaks

Roof leaks can show that water is pooling in certain areas on the roof of your home. Over time, the sealant on the roof will start to deteriorate, and water will seep in under the building materials. Roof leaks can be prevented if water is pushed back into the gutter system the correct way, as opposed to letting it sit on the roof of the home.

Spotting Foundation or Siding Damage

Foundation damage is not always easy to see, but if you see it, the splash shield is undoubtedly necessary. The entire reason behind installing gutters and even gutter covers is to ensure that your foundation stays in great shape long term. Foundation damage occurs quickly when water flow is directed to the foundation of the home.

Landscape Damage

Do you notice that in certain areas around your home, your plants look as though they were trampled? Maybe there is even fungus or mushrooms growing in one small section. This likely has to do with the gutters not being able to manage the amount of rain coming off the house, and it is instead pushed to the ground in one area. If you are not outside during a rain storm and can’t watch the functionality of the gutter system, landscape damage is a great inside look into the problem.

Gutter System Damage

Check out the gutter system and look for signs of damage, water markers, mold, and mildew. You may also see certain gutter areas starting to separate, even with heavy-duty stainless steel gutters. If your gutter system can’t hold up, the splash guards may help to divert water and make this a much more effective system.

How To Attach Gutter Splash Guards

Gutter splash guards, or as some people call them, gusher guards, are very easy to install. This is something that you can do as a DIY project if you do not want to spend the money on a professional installation. The only thing to check here is whether or not you have a warranty on your gutter system that could be voided by you installing a splash guard. Talk to the professional that installed your gutters to confirm.

Gutter guard costs should not be high. The gutter splash guards are sold with pre-drilled holes. Typically a splash guard will have between three and four screws that will go directly into the gutter system itself. Once in place, use a bit of caulk to seal any edges, so you don’t see water spilling out under the splash guard.

This video is a helpful visual, but remember that your gutter splash guard installation will vary depending on the products used and the area of the home where the splash guards are necessary.

Professional Installation

Professional installation of splash guards, downspout diverters, and downspout extenders seem to be favored by most homeowners. When you notice that you need a gutter splash guard, chances are the gutter system is not functioning the way it should.

If gutters are clear of debris and this is not an issue caused by leaf or organic material buildup in the gutter system, then it may make sense to give the company that installed your gutters a call.

The best gutter installation companies will install splash guards in a few areas of the home to ensure that overflow is not an issue. In addition, they are looking to ensure your gutter protection system holds up for years to come.

Professional installation of a gutter splash guard is simple and may be covered under the warranty of your project if your gutters were just installed.

What is a Downspout Splash Block?

When searching for gutter splash guards, you may also see the gutter splash block come up as an option to help with overflow issues from the roof of your home. The gutter splash block is installed at the end of a downspout to ensure water is pushed away from the house and not towards the home. Downspouts on homes that experience heavy rain will often have a puddle of water around them continually. This puddle of water ends up flowing back towards the house, creating long term foundation issues.

Benefits of Splash Blocks

There are a few important benefits of splash blacks that all homeowners should consider. Remember that splash blocks and splash guards may both be necessary for a proper home gutter system.

Can Prevent Basement Flooding

When water collects at the bottom of a downspout, it needs somewhere to go. The downspout does a great job of getting water off the roof and pushing it away from the home, but if the water pools at the bottom of the downspout, it can make its way into your basement. Use a splash block to prevent water issues in your basement.

Easily Installed

Most of the time, the splash block takes minimal effort to install. The only thing to be careful of here is the placement of the block to ensure it is appropriately pushing water away from the home. A professional is sometimes needed if the splash block does not seem like it is doing enough to push water away.

Come In Several Materials

Splash blocks come in several different materials to make it easier to find something within your budget and will work to make your gutter system more efficient. Concrete and plastic are two common types of splash blocks.

Can Decrease Plant and Landscape Damage

When water pools at the bottom of a downspout, expect there to be plant and landscape damage to deal with. Luckily, the splash blocks can divert some of the water and allow for better growing conditions for plants, grass, and other plant material.

Splash Blocks vs. Downspout Extension

A splash block and a downspout extension are not the same things. Downspout extensions are used to extend a downspout and ensure it comes further away from the house. However, depending on the amount of rain you typically get, the extension may still pool with water at the end. The combination of the splash blocks with the downspout extension tends to be a good option for many homeowners.

Are gutter splash guards necessary?

Splash gutter guards are necessary for most homes, but it is highly dependent on the type of roof you have and the type of gutters that were installed. Some homes prepared for larger amounts of rain and installed wider gutters that allow for better water flow.

Other homeowners have installed LeafFilter gutter guards to ensure that there are never any blockages that stop the proper flow of water. If you notice any of the common issues that are caused by poor water flow off the roof, then the gutter splash guards are necessary.

We hope you now have a better understanding of the gutter slash guard, why it is necessary and how your home can benefit from having them properly installed. Remember that LeafFilter is an excellent gutter splash guard installer that can work out any of the issues you are having with your home’s gutter system. Proper water flow from the roof will save you thousands of dollars in home foundation repair; it makes sense to invest in these types of products for your home.

Frequently Asked Questions

Do downspout splash guards work?

Downspout splash guards are typically called splash blocks, and they can work well if positioned correctly. The idea here is to move water further away from the foundation of the home. As the water flows out of the downspout, the splash block ensures that it does not flow back towards the foundation of the home.

How do I stop my gutter from splashing?

If your gutter is splashing water over the side, then a gutter splash guard can make a big difference. This small piece of aluminum is installed to push water back into the gutters and divert it through other areas. In addition, if your downspout is splashing, you can put a gutter splash block in place.

How do you install a gutter splash block?

Gutter splash blocks are installed with the open end away from the house and the closed end on the foundation side of the home. The idea here is to push water into the yard and block it from pooling up and damaging the home’s foundation.
