Traditional K Style Gutters vs Box Gutters Comparison (2024)

When picking out a new gutter system you want to be sure that you are getting one that will work well with your building, whether it be a commercial or residential property. This guide will help you determine what style of gutters are better suited for you, so read on to find out what the difference between K-style gutters and box gutters is!

K-style Gutters

This type of gutter is popular due to its appearance being similar to crown molding and comes in a variety of materials. However, you can find this gutter usually is made from copper, vinyl, steel, or aluminum. This style is most popular in aluminum gutters.

K-style gutters also come in 5 and 6-inch sizes, making them suitable for residential buildings. They can handle a good amount of water and will be able to easily transport the runoff from a home into the ground.

Their unique shape makes them the most durable style of gutter, plus, they can manage the extra weight of debris without pulling away from your roof. This style can also be seamless and we have plenty of customization options with them for you to decide from.

However, because of their sharp angles and corners, K-style gutters are harder to clean- they have a lot of places for debris to hide. Plus, they might hold onto water longer in their crevices, which can cause debris to rot and build up.

Pros and Cons


  • Strong and durable
  • Can hold a lot of water
  • Popular style and pleasant to look at
  • Easy installation
  • Can be made from many different materials
  • Seamless


  • Harder to clean
  • Retain water longer
    • Can lead to issues

Box Gutters

If you want large gutters, you are probably going to want to look into box gutters. They are wider and much deeper than the K-style gutters. They also lack the hard to clean edges that the K-style has. This makes them less decorative, but much easier to clean.

This style is used more often in commercial properties, although you could still use a smaller size on your home. The straight-edged look is appealing to businesses as they outline them well and make them stand out to customers- something about that finished and polished look box gutters give a building makes it look so nice.

If your building experiences a large amount of water runoff, then you are probably going to want box gutters. They are designed to handle much more water than the k-style gutters and are very sturdy. They have few problems, meaning there are no cons to getting them- as long as you want function over appearance.

Custom Box Gutters

With our box gutters, we also have much more customization to offer you. You can choose from a variety of sizes, which is excellent if you need to transport a lot of water.

For example, if buying for a large, commercial property you might want 7 or 8-inch sized gutters. They handle a ton of water. 5 or 6-inch box style gutters would be better suited to a home.

At Storm Master Gutters we also have many different colors and materials for you to choose from for your gutter system. With box gutters, we have noticed that aluminum gutters are the most popular- this style looks nice, is affordable, works efficiently, and can easily match the appearance of your home.

Pros and Cons


  • Large gutters for big homes or commercial buildings
  • Tons of customization options
  • Transport more water than K-style
  • Can be made from many different materials
  • Durable and long-lasting
  • Easy to clean
  • Seamless


  • Not as intricate-looking as K-style

How They Compare

When deciding what kind of gutters you want, you are going to need to be thinking about a few things- do you want large gutters? What material and color will suit your home best? And finally- what style do you want?

The answer to the last question is going to depend on your needs and what you think looks good on your house. If you want function over form, then box gutters are more for you. On the other hand, if you want gutters that look beautiful and do not mind them being harder to clean, then you would be fine with the K-style gutters.

You might be under the impression that box gutters are only for businesses. The box style, while marketed towards commercial properties, actually still works wonders on keeping residential homes dry. Do not let that deter you from trying them out on your home.

Finally, do you want custom box gutters or K-style ones? With the customizable options, you can make either style appear exactly how you want. We have a lot of color choices and different sizing available- all things to think about.

Seamless Gutters

Both of these styles of gutters come in customizable seamless designs. We cut them right at your home using our truck-mounted machinery- meaning you do not need to leave your property to come pick up your gutters for installation.

Seamless designs are also a huge benefit to both types of gutters. Without the extra seams and gaps, there is nowhere for the water to escape. This means less leaking and sagging at the joints!

Since both our box and k-style gutters come with this feature, you can be sure that your water drainage system is going to be sturdy, durable, and leak-free. This goes for whichever style you decide on.


Both styles of rain gutter work well at keeping your property dry and free from water damage. If you have a commercial building you will likely want to consider box gutters over the other types, since box gutters were designed to handle a lot of runoff from flat roofs.

On the other hand, residential buildings have more freedom to choose between the two. It will mainly come down to this- does putting in the extra work to clean your gutters bother you if they look nice?
