How long do copper gutters last?

Well-made copper gutters often last 50 years or more. Heavier sheet, soldered seams and allowances for expansion help them reach the top of that range.

Do copper gutters turn green?

Usually, eventually. They go brown first, then may develop a green patina over 10 to 30 years depending on climate. Coastal and humid areas green fastest.

Can I put copper gutters on a white house?

Yes, and it is a classic look. Bright copper darkens to brown within months, so expect a warm brown line against the white for many years before any green appears.

Are copper-look aluminum gutters a good option?

They are a good budget option for the look. They cost close to standard aluminum, but they will not patina and the paint can fade over time.

What is the copper gutter price per foot?

Copper costs several times as much per foot as aluminum. The cost per foot page gives the published ranges.

Copper Gutters: Patina, Weights, Soldering and Lookalikes

Copper is the gutter material people choose for looks and lifespan rather than price. It can outlast the roof and the people who paid for it, but it asks for skilled installers and a clear idea of how it will look in ten years.

Copper gutters show up on historic homes, high-end new builds and houses where the owner wants the roofline to be a feature. They are made from sheet copper formed into half-round or K-style troughs, joined with soldered seams rather than sealant, and hung on copper or brass hangers. Done well, a copper system can last half a century or longer with little more than cleaning.

Because copper costs several times as much as aluminum, it pays to understand what you are buying before asking for quotes. Copper pricing is covered on the copper section of the gutter cost per foot page; this page explains the material itself.

How copper ages

New copper is bright and pinkish-orange. Within weeks outdoors it begins to darken to a penny brown, then over several years to a deep chocolate. In most climates it eventually turns the familiar blue-green patina, called verdigris, though that can take 10 to 30 years and depends on rain, air pollution and salt. Near the coast it greens faster; in dry inland areas it may stay brown for decades.

The patina is a protective layer, not damage. It is the reason copper needs no paint. Some owners like the bright new color and ask for a clear lacquer to hold it, but lacquer wears and needs renewing. Others buy pre-patinated or aged copper so the gutters match an older roof from day one.

Copper weights and thickness

Copper sheet is described by weight per square foot in ounces. Residential gutters are usually made from 16-ounce or 20-ounce copper. The heavier sheet is stiffer and better for wide gutters, long runs and areas with heavy snow, and it is the usual choice for 6-inch half-round systems. Lighter copper is cheaper but can dent and wave. Ask for the weight on the quote, along with the hanger type and spacing.

Copper gutter installation: soldered seams instead of sealant

Copper gutters are joined by soldering: the overlapping pieces are cleaned, fluxed and heated, and solder flows into the seam to make a permanent watertight joint. A soldered joint does not dry out the way sealant does, which is part of why copper lasts. It also means the installer needs real sheet-metal skill. Poorly soldered joints crack, and patching them later is slower than replacing a sealant bead.

Long copper runs expand and contract more than people expect. A good installer allows for that movement with expansion joints on long straight runs and hangers that let the gutter slide slightly. Without them, soldered seams can crack after a few seasons of hot days and cold nights.

Half-round or K-style copper

Most copper gutters are half-round, because the simple curve suits the traditional homes where copper is most common and shows off the metal. Copper K-style exists and works well on colonial and modern homes that already have K-style elsewhere. Round copper downspouts usually pair with half-round gutters, and rectangular downspouts with K-style. The K-style versus half-round page goes deeper into the two shapes.

Copper and other metals

Keep aluminum away: aluminum touching copper, or downstream of it, corrodes quickly. Copper runoff onto an aluminum gutter below will eat it.
Use copper or brass hangers and fasteners: galvanized or steel fasteners rust and stain.
Watch the stains: copper runoff can leave blue-green streaks on light stone, concrete and siding. Splash blocks or extensions help.
Match the flashing: if the roof has copper flashing or valleys, copper gutters keep the metals consistent.

Copper colored gutters and faux copper aluminum

If the look matters more than the lifespan, copper-colored aluminum is a popular alternative. Coil makers offer copper penny, copper metallic and aged copper finishes painted onto standard aluminum. From the street, a copper-look gutter on a white house gives much of the same effect for a fraction of the price. It will not patina, and the finish is paint, so it may fade over time like any painted aluminum.

The trade-off is honest: faux copper gutters are an appearance choice, not a durability one. If the house will be sold in a few years, or the gutters will likely be replaced in a remodel, copper-look aluminum often makes more sense than solid copper.

Copper gutters cost: is copper worth it?

Copper tends to be worth the money on a house you plan to keep for a long time, on historic and high-end homes where it suits the architecture, and where the roof is also long-lived, such as slate, tile or standing-seam metal. Pairing a 60-year gutter with a 20-year shingle roof means the gutters may come down when the roof is replaced, which adds risk of damage.

It is harder to justify on a starter home, a rental or a house with heavy tree cover that will need frequent cleaning. Copper is also a theft target in some areas, especially downspouts within reach of the ground.

Looking after copper gutters

Clean copper gutters as often as any others; debris sitting in the trough holds moisture and acids that can pit the metal over many years. Do not use harsh cleaners on the outside unless you want to strip the patina. Check soldered seams after each winter and have any crack re-soldered before water gets behind the fascia. Contractors in our network who work with copper can quote both installation and seam repair.

Copper downspouts and accessories

A copper system is more than the trough. Round or rectangular copper downspouts, soldered outlets, decorative leader heads and copper rain chains all add to the look, and each one should be the same metal to avoid corrosion and mismatched aging. Ask whether the quote includes copper straps for the downspouts, because cheap steel straps will rust and streak within a few seasons.
