Gutter materials

By Gutter Report Editorial. Last reviewed August 2026. How we research this.

In brief

Five materials are worth a look. One of them is right for most houses. Aluminum costs $10 to $20 a foot installed and lasts 20 to 30 years. That is the default. Vinyl is cheaper at $8 to $12 a foot, but it only lasts 10 to 20 years. Galvanized steel is stronger. It also rusts once the coating wears through. Copper runs $25 to $40 a foot and lasts 50 to 100 years. Zinc costs the most at $35 to $45. It acts like copper without the color. That is the whole material decision. Shape is a separate question, and so is seamless against sectional, because most of these metals come both ways. The figures here come from HomeGuide, Fixr, Angi and This Old House, all read in August 2026. Where they disagree, this page prints every figure instead of picking one.

Five gutter profiles stood end-on and backlit, so each cross-section reads as a solid dark shape: ogee, half-round, square, fluted and deep box.

1.0The comparison

Material	Installed	Service life	The short verdict
	USD per ft	Years
Aluminum	$10 to $20	20 to 30 years	The default, and the right answer for most houses.
Vinyl	$8 to $12	10 to 20 years	The cheapest install and the shortest life. A short-term answer.
Galvanized steel	$5 to $20	20 to 50 years	Stronger than aluminum, and it rusts once the coating is through.
Copper	$25 to $40	50 to 100 years	The one that outlives the roof, at four times the price.
Zinc	$35 to $45	30 to 80 or more years	Copper economics without the color. Rare in the US.

Installed rates come from HomeGuide. The one exception is galvanized steel, which HomeGuide does not price and Fixr does. Service life is the first published figure in each row. The other publishers are on each material's own page, because they do not all agree.

2.0Where the publishers disagree on service life

A gutter's life is the number most likely to decide a purchase, and it is the number the publishers agree on least. Here is every figure we found, by publisher.

Material	Published service lives
Aluminum	20 to 30 years (HomeGuide); around 25 years (Angi); 20 years or more (This Old House)
Vinyl	10 to 20 years (HomeGuide); 10 to 15 years (Angi); around 10 to 20 years (This Old House)
Galvanized steel	20 to 50 years (HomeGuide, for steel generally); 15 to 20 years (Angi, for galvanized specifically); generally 20 years or longer (This Old House); 15 to 25 years (This Old House, in its half-round comparison)
Copper	50 to 100 years (HomeGuide); 50 to 100 years (Angi, grouped with zinc); up to 100 years (This Old House)
Zinc	30 to 80 or more years (HomeGuide); 50 to 100 years (Angi, grouped with copper); 80 years or more (This Old House)

Aluminum and copper are close enough across publishers to plan around. Galvanized steel is not. Angi says 15 to 20 years. HomeGuide says 20 to 50 for steel in general. That spread is wide enough to be two claims about two different products.

The one non-commercial source, and what it says

Every figure above comes from a company that sells advertising to contractors. One source does not. The National Association of Home Builders, with Bank of America, published a Study of Life Expectancy of Home Components in 2007. It gives aluminum gutters a flat 20 years, aluminum downspouts 30, galvanized steel a flat 20, and copper 50 or more, with copper downspouts around 100.

It is the low end on aluminum, where the cost guides say 20 to 30 and it says 20. On copper it agrees with everyone. It is old, and it does not cover zinc or vinyl at all. We name it separately rather than blending it in, because a study and a cost guide are not the same kind of thing.

3.0Pick the material, then the profile

Shape or spec	What it is	What it costs against the baseline
K-style	The ogee front face on most American houses. The default	The baseline every table prices against
Half round	A semicircle. The older profile, and the one on period houses	$1 to $2 a foot more, per HomeGuide
Box and built-in	Two things: a historic trough inside the roof, or a deep commercial profile	$15 to $50 a foot, depending on the publisher
Seamless	Rolled to length on site, so the straight runs have no joints	$3 to $5 a foot more than sectional, per HomeGuide
6 inch instead of 5	About 40 percent more water, per Englert	About 30 to 40 percent more metal, and the same labor

These are separate decisions and people run them together. K-style and half round are both made in aluminum, steel and copper. Vinyl is the exception, sold in molded sections in one profile. Seamless gutter is rolled on site from a coil of metal, and we found no vinyl sold that way.

HomeGuide prices the half-round profile at $1 to $2 a foot above K-style in the same material. That is the profile premium, and it is small next to the gap between materials.

4.0You may not need to change material

Most people reading a materials comparison have aluminum gutters and a specific problem: a leak, a sag, or overflow in heavy rain. None of those is a material fault. A leak is a seam, a sag is a hanger, and overflow is usually slope or too few downspouts.

Aluminum at 20 to 30 years outlives most reasons to replace it. If your gutters are 12 years old and one section drips, upgrading the whole system to copper is a $25 to $40 a foot answer to a problem that a repair at a national average of $275 solves. We can say that plainly because we do not sell gutters and we do not install them.

Common questions

How long do gutters last?

It depends on the material, and the publishers disagree. HomeGuide gives vinyl 10 to 20 years, aluminum 20 to 30, steel 20 to 50, zinc 30 to 80 and copper 50 to 100. Angi is shorter on steel at 15 to 20. The National Association of Home Builders, the only non-commercial source we found, is more conservative: a flat 20 years for aluminum gutters and for galvanized steel, 30 for aluminum downspouts, and 50 or more for copper, with copper downspouts near 100.

Is copper worth it?

Only if you are keeping the house or selling it on appearance. Copper runs $25 to $40 a foot installed against aluminum at $10 to $20, so it costs roughly twice to four times as much. It buys 50 to 100 years instead of 20 to 30, which is real, but the payback is longer than most people own a house.

Does the material change the profile I can get?

Mostly no. K-style and half round are both sold in aluminum, steel and copper. Vinyl is the exception. It comes in molded sections in one profile, and seamless gutter is roll formed on site from metal coil, which is not how vinyl is made. We found no seamless vinyl sold.
