Seamless Gutter Sizes

At All Season Gutters, all of our seamless gutter systems are custom designed to fit your needs in an effort to eliminate all future problems when properly maintained. Each section of our Seamless Gutter Systems is measured and run out on site to ensure a perfect fit for every part of your home. For lifetime, worry-free gutters, we use the thickest aluminum, and the best-hidden hangers on the market to stand up to tough winters and strong storms.

All of our seamless gutter systems run anywhere from a few inches to 100 feet. We offer both the standard 5” K style gutter and the larger 6” K style gutter for larger homes, steep roofs, and problem areas.

Standard 5″ K Style Gutters: The 5” K-style gutter is the most common size and style that you see on homes and might also be referred to as an ogee style. They are the residential industry’s standard, with a water collection opening of 4.25” and can hold 2 ½ quarts of water per foot. The standard downspout size for this application is the 2×3, however, we can also add larger 3×4 downspouts to the standard 5” gutter.

Larger 6″ K Style Gutters: The 6” K-style gutter is an excellent option for problem areas such as steep valleys, roofs, or long runs of gutter without adequate downspouts. These can be installed on any home from ranch style to micro-mansion without affecting the look of the home. One foot of 6″ K-Style gutter holds 2.0 gallons of water and will prevent damage from heavy rainfalls and large amounts of snow. The standard downspout for the 6” gutters is a 3×4 downspout which allows for water to move away from the home at a much faster rate preventing erosion and foundation damage.

Determining the Size of Your Gutters

No two homes are alike! Whether it is a large estate or residential home, every gutter project has their specific needs. Though 5″ and 6″ gutters are the standard gutter dimensions, there are multiple factors, such as architecture and geography, that determine the gutter size you need. Here are some factors to help you choose the correct gutter size for your home.

Gutter Drainage Area: In order to figure out what size gutter you need, you will need to calculate the square footage of the gutter’s drainage area. The bigger the square footage, the bigger gutter you will need. Once you figure out the square footage, you can adjust your calculation for your roof’s slope and rainfall intensity in your area.

Roof Size: When determining gutter size, it is important to look at the number of shingle squares. This will give you an estimate of how many gallons of water comes off the roof during a storm. The bigger your roof, the more water it will generate.

Slope: The slope of your roof is also another factor. The steeper your roof is, the faster water will come down from it. Therefore, we recommend you choose a bigger gutter.

Geography: Location is another important factor when choosing the right gutter size for your home. When choosing between 5″ and 6″ gutters, it is important to ask yourself, “Am I in an area like Florida that gets frequent downpours? Or in an area such as the Northeast who get a few rainstorms in a year?” The more rainfall in your area, the bigger your gutter system should be.

They replaced our gutters with larger gutters and made sure all connections and elbows were correctly connected and secure. They also worked without being on their phones. Well-mannered and, before starting any work, rang the bell and introduced themselves. I asked them to push the screen corner into place, and they did this with a smile. Very happy and pleased with this entire process of replacement. They cleaned up afterward, including any stray nails. Fully recommend this team of Sean and Chris with All Season Gutters. Well done! I can’t remember the last time I have been able to say this about a company or staff.

I never pictured myself writing a review for a gutter installation, but Chris and Sean did a truly outstanding job. They were upbeat, pleasant, worked quickly and efficiently and the quality of the installation is incredible. I would give them more than 5 stars if possible! All Seasons Gutters is where it’s at!

In 2014, I found Jeff and Amy and All Season Gutters. They have become friends over the years. Wonderful people running a fantastic business. A veteran-owned local business. I have seen them do numerous jobs and their crews take care of the job like it was their own house. They do the details I wouldn’t do to my own house! This week they did a three-day job on our house and helped transform it. We can’t thank them enough. I will never go elsewhere and haven’t for 8 years. New siding, gutters, and metal work for the whole house. Some small things to finish up like replacing the lighting, doorbell, etc ahead but we LOVE it. Thank you, Jeff and Amy and the All Season Gutters Crew!

Would definitely recommend All Season Gutters to my family and friends! They took off our old gutters and replaced them with new ones; they look beautiful! They showed up on time, even on a cold, snowy, morning. They even helped me take up my garbage cans! They were super friendly, efficient, and cleaned up afterward. We are thrilled with how it all looks.

The entire crew of All Season Gutters worked hard in extreme wind conditions. They ensured that quality work would be performed and it was! Jeff and Amy (owners) are FABULOUS and a pleasure to work with! We originally requested gutters and downspouts but ended up adding all-new facia and soffit because of the team’s hard work, great pricing, and dedication to the job and customer. We couldn’t be happier and highly recommend All Season Gutters!
