This comprehensive seamless gutter guide includes gutter styles and sizes, materials, options, cost per linear foot and FAQ.

Quick Answer – What are Seamless Gutters?

They are gutters produced from rolls of material run through a forming machine to give them the shape you prefer. They are made in the exact length you need for each section of roof. Having no seams means they won’t leak or come apart in the middle of a gutter run.

The process: You hire a seamless gutter company, pick your material, gutter size, shape, and color. Guidance is offered, when needed. The crew shows up with a truck loaded with s roll-forming machine and sheet metal coils of material in a range of widths and colors.

Your gutters are measured and formed onsite and installed on your home. Ends are capped, and support brackets and downspouts are installed at appropriate locations.

Done – in less than a day for most jobs.

Cost per Linear Foot

Seamless gutters cost $9.00 to $22.00 per linear foot for most materials except for copper. This price range includes the cost of materials and professional labor to install new seamless gutters including any necessary downspouts, brackets, and endcaps.

Project Cost Factors

The main variables impacting the total cost of a project is your home’s location and local real estate market, accessibility, and overall complexity of the project. If old gutters are difficult to remove due to some project-specific constraints or if additional repairs like replacing any damaged or rotten fascia boards are needed before the new gutters can be installed, then your total project costs are going to be higher.

Did you know? The best time to install new gutters is right after re-roofing or re-siding project.

Can you DIY seamless gutters? No.

Installation – It’s part of all seamless gutter jobs. That’s what you’re buying – the gutters and installation. We’re not aware of a seamless gutter company that will make gutters and downspouts for you and let you install the gutters to save money.

Seamless Gutter Material Options

What are seamless gutters made from?

Painted aluminum and coated steel make up more than 80% of all residential gutters.

But the full range of options available in your area probably includes galvanized steel, stainless steel and copper in addition to aluminum and coated steel. Most will carry the last two materials – some will not have all the other choices available.

Here are the pros and cons of each seamless gutter material.

Aluminum – Painted: #1 Best Seller

This metal is light, so it is easy to work with, and quite durable. And aluminum doesn’t corrode. These traits make it the most popular gutter material.

Aluminum seamless gutters are painted – and the finish is a powder coat that is baked onto the metal. If the paint wears off or is scratched, the aluminum beneath will not rust. Aluminum gutter systems are strong enough to handle minor ice buildup and impact from thin branches and twigs falling onto them but can be damaged in more extreme conditions.

Your color options include white, black and 8 to 20+ other colors offered by most seamless gutter installers.

Durability: 20-25 years.

Steel – Coated: #2 Best Seller

Steel is stronger than aluminum, so it is a good choice where heavy ice and damage from larger branches are possibilities.

You have fewer color options with steel than with aluminum, but you should still be able to find something fitting for your home.

Coatings for steel seamless gutters include siliconized polyester ($-$$) and Kynar 500 / Hylar 5000 ($$-$$$) paint finishes like those used on metal roofs. They are very durable and don’t easily chip or scratch. Cheaper coatings may be available too, but they can be scratched more easily, allowing rust to begin to mar the appearance and performance of seamless steel gutters.

Durability: 15-25 years, but when rust appears, it must be immediately treated with a rust inhibiting paint if you want these gutters to last.

Steel – Galvanized: Affordable and Time Tested

Seamless galvanized steel gutters are bare galvanized steel, and as you can imagine, the “look” isn’t a good fit for every home – most designers suggest them for modern-style homes, if at all. You might like them on a rustic home with wood siding too.

Galvanized steel seamless gutters have a pure steel core. It is covered in layers of galvanized steel – steel treated with a mix of iron and zinc coating covered by a top layer of pure zinc. The process is called hot dipped galvanization.

If you want a specialty material, G-90 galvanized steel is typically the most affordable option when compared with Galvalume, stainless-steel, and copper. Galvanized steel won’t readily corrode/rust, and it is tough, so the material is resistant to scratches that could penetrate to the steel core. And it is stronger than other seamless gutter material options.

Durability: 15-20 years if you want the gutters looking “like new.” That’s not as long as aluminum – and about the same as painted steel. After about 15 years, you might begin to see corrosion developing where it has been scratched or damaged.

Steel – Galvalume: Better than Galvanized

Galvalume seamless gutters have a steel substrate that is coated with Galvalume, which is a mix of 55% aluminum and 45% zinc, two metals with proven resistance to corrosion and scratches. The coating handles temperature changes very well, so is a good choice where weather is extreme.

Durability: The durability of Galvalume gutters is 40+ years – 70 years is not out of the question. In fact, one gutter supply site that sells gutters made in both materials claims, “Galvalume coating, on average, will last 1.5 to 2 times longer than galvanized.” While that seems like exaggeration, there’s no doubt this is a more durable material with excellent long-term value.

Galvalume seamless gutters cost is second only to stainless steel and copper as the most expensive material option, but its durability makes it a good long-term value. The “lifetime” cost is quite low compared with coated steel or galvanized.

Steel – Stainless: Bright and Corrosion-free

This is a fitting choice for modern homes with an urban or industrial design, though it can be effectively used with other architectural styles.

Stainless isn’t cheap, but it is durable. Seamless stainless-steel gutters resist rust, and so they should look good for decades. Choose a thicker grade of stainless steel, so that its durability against dents and sagging will match its long-lasting good looks.

Durability: 20-35 years

Copper: Classic Elegance and Charm

Freshly installed seamless copper gutters are classic reddish gold and very bright. With time, unless it is cleaned, the copper develops a green-brown patina that gives it antique charm. Special sealers can be applied to delay the development of patina. Whether you prefer a bright copper or patina look is a matter of preference and your home’s overall style – it does not affect durability.

While expensive, copper gutters often prove the perfect finishing touch on upscale homes sided with wood, some brick colors, stucco, or a combination including stone.

Durability: Quality copper gutters can last 50-100 years when maintained.

What about vinyl?

Making seamless gutters requires a mobile unit with materials onboard to produce the gutters to exact lengths. This is easy to do with coils of metal that are run through a gutter machine to shape them. It isn’t currently feasible to do with vinyl, which is produced from granular material which is heated and extruded.

Long story short – seamless vinyl gutters are not available.

Gutter Profiles and Sizes

There are a few gutter shapes that account for the majority of all seamless gutters.

K-style gutters are most common by far. They have a flat side that is installed against the home’s fascia, the horizontal board at the eaves of your home.

The outward side of the gutter looks something like the letter K if you use a little imagination.

You’ll also see the term K-style Ogee seamless gutters, or simply Ogee gutters. The names are synonymous.

Half-round gutters are the second-most common profile, but it’s a distant second.

K-style seamless gutters are produced in 5” and 6” wide versions – with the measurement made at the top, or widest span, of the gutter – because those are the two sizes of gutter machines currently manufactured for producing seamless gutters.

If you need wider K-style gutters up to 8” or 10”, you’ll have to purchase them in prefab sections.

Half-round gutters are manufactured in 1-inch increments from 5” to 10”, but 5” and 6” are the most common sizes for residential installation.

Sizing Seamless Gutters

Your gutters must be the right size and have enough downspouts to handle the volume of water your roof is likely to experience.

For seamless gutters, the gutter contractor will make the determination of gutter size and the spacing of the downspouts. These decisions are based on:

The roof size/square footage to be drained

Maximum rainfall intensity, defined as the inches per hour of rain during the heaviest rainfalls of the year

Roof pitch – The steeper the roof, the faster the water is moving when it hits the gutters, so steeper roofs require wider gutters to prevent water from overrunning them

According to one experienced installer, “5-inch K-style gutters or 6-inch half-rounds, the most common residential sizes, are able to handle the rainfall on most houses in most parts of the country.”

If your roof is very large, quite steep or you get frequent heavy rains, your options are to choose a larger gutter size, add extra downspouts or raise the outer edge of the gutters, tipping them toward the roof, to prevent overflow from rapidly flowing water. A combination of those solutions might be used.

Because of these complexities, it makes sense to hire an experienced gutter contractor when any of the gutter size factors are a concern – large roof, steep slope, or heavy rains.

What are the advantages of seamless gutters?

Seams are where sectional gutters tend to leak or even come apart. Those issues are eliminated with seamless gutters.

What are the disadvantages of seamless gutters?

The main “con” of seamless gutters is that you can’t cut costs by DIY. They’re installed by local gutter companies that sell the whole package – the gutters and downspouts plus installation.

Which is better, steel or aluminum gutters?

They both have pros and cons. Aluminum won’t rust, so its appearance looks good longer. But aluminum is softer, so it is more susceptible to damage from falling debris, ice and even high winds.

Steel costs a little more and it can rust, but it is stronger than aluminum. It is a better choice in harsh climates, especially where heavy snow and ice are possible.

What colors are available?

Most seamless gutters made from aluminum and painted steel are produced in 10-20 colors.

Classic gutter colors

How do I know when it is time to replace gutters?

When their performance and/or appearance is failing. Issues signaling a need for gutter replacement include leaks caused by misshapen or sagging gutters, damaged end caps and downspouts that don’t fit and allow leaking, corrosion or appearance marred by age, mold, algae staining or corrosion.

Also, if the gutters are too small for your roof, then replacement is essential. Only properly sized gutters will effectively move water off the roof and away from your home’s foundation. Failing and undersized gutters are a major source of large amounts of water falling close to the home and leaking through the foundation.

What’s the warranty on seamless gutters?

Materials are typically covered by a warranty of 10-20 years. Workmanship warranties range from 1-10 years. These warranties cover issues caused by improper installation such as not effectively sealing caps and downspout connections.

Should I replace the fascia when replacing gutters?

The fascia board should be examined for signs of rot or warp. If it’s in good condition, it can stay. Otherwise, it’s a good idea to replace the fascia board when getting new gutters.

How long does it take to install seamless gutters?

A day or less for most homes. The work moves quickly with a crew of 2-4 people. Measurements are taken, and it requires one person to make the gutters and two people to install them.

K-style vs half-round gutters. Which is better?

K-style, or Ogee, gutters hold more water for the same size. One foot of 5″ K-Style gutters holds 1.2 gallons of water; a foot of 5” half-round gutter holds about .9 gallons. One foot of 6″ K-Style gutters holds 2.0 gallons of water while a 6” half-round gutter holds 1.6 gallons of water.

Half-round gutters are easier to clean.

The rest is about appearance. K-style Ogee gutters are the “norm,” so they’re accepted on homes of any style. Half-round gutters have a uniquely traditional look suitable for very traditional homes like classically designed wood-sided homes in historic districts.
