They are installed with larger 3 x 4 downspouts for better water management. Five-inch gutters can hold significantly less water than six-inch gutters. This can quickly cause gutters to overflow, especially if they are clogged. This can turn into water that returns to your home instead of being diverted from it.
Possible consequences include problems with the foundation, an overwatered lawn, and mud splashes against the coating. All of these elements detract from the curb appeal of your home. You might think that a 1-inch increase in channel size wouldn't make a big difference in performance. Surprisingly, 6-inch gutters can handle significantly more water.
In addition, larger gutters can better handle debris and are less likely to become clogged with leaves and other common items thrown into gutters. Before 5-inch gutters became omnipresent, smaller gutters generally had simple half-tube configurations. But the K-style profile has more depth. Of course, 5-inch K-type gutters outperform narrower models, as long as the drains and discharge pipes themselves allow as much unobstructed flow to the floor as possible.
A simple upgrade of 5″ to 6″ gutters can increase your rain collection considerably. If your gutters have struggled to withstand the water that comes out of the roof during a storm, it's time to improve them. This will protect your base by allowing the maximum amount of water to be redirected away from your home. It will also protect the plants below the canals and prevent channels from forming after the rain.
There are a lot of things to consider when it comes to choosing the right size gutter and, as a general rule, a 5″ gutter is usually acceptable for most residential applications. While larger gutters aren't always better, upgrading to a 6-inch gutter could definitely be a solution to frequent overflow problems. But cleaning gutters twice a year (at least) presents every homeowner with a dangerous and unpleasant task. You'll never feel pressured to buy larger gutters or high-end gutter protectors if they're not needed for your property.
If your home has this feature, the lower gutters would benefit from being upgraded to 6-inch gutters to prevent overflows. When it's time to clean the gutters, the 6-inch gutters will give you a big advantage because the mouth at the top is an inch wider and gives you more room for your hand. If the gutter can cause stormwater to flow quickly out of the roof, but finds a choke point in the downspouts, the width of the gutters won't make much difference. Before you get caught up in sales arguments about what size gutter is best for your home, you need to make sure you're sizing the gutters correctly for your downspouts.
In recent years, more and more homeowners are making the switch from the standard 5-inch gutter to the large or commercial 6-inch gutter. Moving from 5-inch gutters to 6-inch gutters could significantly improve your drain efficiency. Compared to other gutter sizes, having a six-inch gutter allows more water to accumulate inside the canal.
