Copper vs aluminum gutters comes down to price against lifespan: copper costs $15 to $40 per linear foot installed and is rated at 50+ years by NAHB and InterNACHI, while seamless aluminum costs $6 to $12 per linear foot installed and averages about 20 years per NAHB (20 to 40+ years on InterNACHI’s chart). The copper range is from HomeGuide’s copper gutter cost guide (November 2025) and the aluminum range from HomeGuide’s aluminum gutter guide, with HomeWyse putting basic seamless installs at $6.29 to $10.45 per foot (May 2026). Copper wins on lifespan and soldered, caulk-free joints; aluminum wins on upfront price and color choice. The deciding inputs are your hold time, your budget per foot, and whether the gutters will touch other metals on the roof.
Copper vs aluminum gutters: side-by-side comparison
The table compares the two materials on the figures that move a buying decision, with the source for each row. Prices are U.S. installed figures for standard 5 in and 6 in residential profiles; seamless copper and two-story work sit at the top of each range.

What are copper gutters?
Copper gutters are troughs formed from cold-rolled copper sheet to ASTM B370, with joints soldered rather than sealed with caulk. The Copper Development Association’s guide specification calls for 16 oz per sq ft (0.0216 in) copper on hung gutters and downspouts and 20 oz (0.0270 in) on built-in gutters. Copper does not rust. It forms a patina that shifts from bright penny-brown to darker browns and, in most climates, to blue-green; CDA’s patina finishes page puts the green stage at five to seven years in coastal or industrial air, longer in rural areas, and says it may never develop in some climates. Copper is common in half-round profiles on historic homes. Buyers weighing other premium metals can compare our copper vs zinc roof comparison. For the build details, see our copper gutters guide (weights, seams, and install specs).
What are aluminum gutters?
Aluminum gutters are troughs roll-formed from prefinished aluminum coil. HomeGuide says contractors typically use 0.027 in stock in moderate climates and 0.032 in to 0.040 in where ice is common, and HomeWyse’s seamless estimate assumes prefinished K-style stock 0.031 in thick with a 20-year limited finish warranty. Aluminum will not rust, comes in baked-on colors, and can be run seamless from a truck-mounted machine. The trade-offs are lower dent resistance and shorter life: NAHB averages aluminum gutters at 20 years. Aluminum also competes with cheaper vinyl and heavier steel, which we break down in our vinyl vs aluminum gutters guide and steel vs aluminum gutters comparison.
Copper-look aluminum: Copper Penny and other coppertone gutters
Coppertone aluminum gutters are standard aluminum coil with a copper-colored painted finish, not copper. Lynch Aluminum lists Copper Penny Metallic among 21 colors for its 0.032 in x 15 in gutter coil, and Gutter Supply sells complete Copper Penny Aluminum and Designer Copper Aluminum gutter systems. They cost aluminum prices and carry aluminum’s lifespan, and the paint does not weather to brown or green, so the look stays new-penny bright while real copper darkens within months.
| Option | What it is | Installed cost per foot | Ages to patina? | Source |
|---|---|---|---|---|
| Solid copper, sectional | 16 oz copper, soldered seams | $15 to $30 | Yes | HomeGuide, Nov 2025 |
| Solid copper, seamless | Roll-formed copper | $30 to $50 | Yes | HomeGuide, Nov 2025 |
| Copper Penny or Designer Copper aluminum | Painted aluminum coil | Aluminum pricing, $6 to $12 seamless | No, finish stays as painted | Gutter Supply; HomeGuide |
| Standard aluminum, painted to order | Painting existing gutters | $1 to $4 added for paint | No | HomeGuide aluminum guide |
How much do copper and aluminum gutters cost?
Aluminum is the budget pick and copper the premium pick. At the midpoints of HomeGuide’s installed ranges, copper ($27.50 per foot) costs about 3 times seamless aluminum ($9 per foot); at the extremes the gap runs from about 1.3 times to 6.7 times. Copper materials alone run $12 to $30 per linear foot with downspouts, and labor adds $3 to $10 per foot, per HomeGuide’s November 2025 copper guide.
| Gutter length | Seamless aluminum at $6 to $12 / ft | Copper, HomeGuide totals | Source |
|---|---|---|---|
| 100 linear ft | $600 to $1,200 | $1,500 to $4,000 | HomeGuide (copper table; aluminum rate x length) |
| 150 linear ft | $900 to $1,800 | $2,200 to $6,000 | HomeGuide |
| 200 linear ft | $1,200 to $2,400 | $3,000 to $8,000 | HomeGuide |
HomeGuide’s material table also shows what moves copper prices: a 6 in copper gutter runs $10 to $15 per foot in 16 oz and $14 to $19 in 20 oz, and a 7 in gutter $13 to $23 in 16 oz and $25 to $38 in 20 oz, before labor. Copper downspouts add $14 to $34 per foot, and HomeGuide plans one downspout per 30 to 40 feet of gutter. For a full breakdown by profile and gauge, see our aluminum gutters cost guide and the average cost of gutters by home size.
Cost per year of service
Upfront price hides the real gap. Dividing installed cost by a published lifespan gives a rough annual figure. This is a Roofing Brief calculation using the midpoints of HomeGuide’s installed ranges and the NAHB and InterNACHI lifespans, not a quoted price.
- Aluminum: $9 per linear foot installed over 20 years (NAHB average) is $0.45 per foot per year, or about $0.23 over 40 years (the top of InterNACHI’s range).
- Copper: $27.50 per linear foot installed over 50 years (the NAHB and InterNACHI floor) is $0.55 per foot per year, or about $0.28 over 100 years (the top of HomeGuide’s 50 to 100 year range).
At the published figures the two land in the same $0.23 to $0.55 per foot per year band, so copper only comes out ahead if it outlasts the aluminum system it replaces by decades and you or later owners keep the house long enough to bank them. Over a 10-year hold, aluminum is cheaper: a 200 ft seamless aluminum job at $9 per foot is $1,800 against $5,500 for copper at $27.50.
Which lasts longer and holds up better?
Copper lasts longer in nearly every climate. NAHB’s 2007 Study of Life Expectancy of Home Components rates copper gutters at more than 50 years and copper downspouts at 100 years, against 20 years for aluminum gutters and 30 years for aluminum downspouts. InterNACHI’s chart lists copper gutters at 50+ and aluminum gutters, downspouts, soffit and fascia at 20 to 40+. Copper sheet at 0.0216 in is thinner than 0.027 in aluminum coil but about 3.3 times denser (8.96 vs 2.70 g per cubic cm), which is why HomeGuide lists copper gutters at 0.80 to 1.50 lb per foot and CDA specifies brackets no more than 30 in on center to carry them.
Aluminum still performs well for the money. It will not rust, handles freeze-thaw cycles, and the top of InterNACHI’s 20 to 40+ year range shows a well-installed system can last well past 20 years. HomeGuide recommends 0.032 in to 0.040 in stock where ice is common, which is the cheapest durability upgrade available. Its weak points are cut edges, sealed seams that can leak over time, and a soft body that dents. Copper’s soldered joints have no sealant to fail. For the published numbers on every material, including coastal figures, see our breakdown of gutter lifespan by material, per NAHB and InterNACHI.
Installation differences that affect cost and longevity
Installation method is where these two diverge most. Aluminum is usually run seamless on site, so a 40 ft run has no joints between its end caps. Copper is cut and soldered by hand, which is why HomeGuide puts copper labor at $3 to $10 per foot, and CDA calls for expansion joints no more than 24 ft from an inside or outside corner on copper runs.
- Confirm the profile. Aluminum favors K-style; copper is common in both K-style and half-round, and HomeGuide prices copper gutters in 5 in, 6 in and 7 in widths. Compare shapes in our gutter dimensions spec sheet, and weigh trough shapes in our box gutters vs K-style gutters comparison.
- Choose seamless or sectional. Seamless aluminum costs $6 to $12 per foot against $4 to $8 sectional in HomeGuide’s guide; seamless copper runs $30 to $50. See how roll-forming works in our seamless gutter systems guide.
- Match the hangers and fasteners to the metal. CDA specifies copper, brass or bronze brackets for copper gutters, spaced no more than 30 in on center for most climates.
- Hire for soldering skill on copper. CDA’s guide specification calls for ASTM B32 solder (50-50 tin/lead or a lead-free alternative of similar strength); ask the crew which solder and flux they use and whether every joint is soldered rather than sealed.
The mixed-metal problem most guides skip
Copper cannot safely touch aluminum or zinc. The CDA Design Handbook ranks common construction metals by nobility in Table 1.3A, with aluminum lowest and copper above every metal except passive stainless steel, and says the metal with the lower number deteriorates when the two touch in the presence of rainwater. CDA names aluminum and zinc as the principal metals of concern; iron and steel are generally a problem only when their mass is similar to or smaller than the copper’s.
Two practical consequences follow. First, copper gutters need copper, brass, bronze or stainless fasteners and hangers; CDA says isolating copper from stainless steel, lead or tin is not necessary in most cases. Second, the CDA Design Handbook warns that wash from copper surfaces should not drain onto exposed aluminum, because traces of copper salts accelerate aluminum corrosion, so a copper gutter draining onto an aluminum roof or awning is a poor pairing. Where the metals must meet, CDA lists bituminous or zinc chromate primers, or taping and gasketing with nonabsorptive materials, as separators.
Which gutter should you choose?
Use the thresholds below rather than a single winner; the break points are hold time, price per foot and metal contact.
| If | Choose | Why (source) |
|---|---|---|
| You will own the house fewer than 20 years | Seamless aluminum | 20-year NAHB average; $6 to $12 per ft (HomeGuide) |
| You will own it 50+ years, or it is a historic home with half-round gutters | Copper | 50+ year rating (NAHB, InterNACHI) |
| Budget is under about $2,500 for 200 ft | Aluminum | Copper starts at $3,000 for 200 ft (HomeGuide) |
| You want the copper color at aluminum cost | Copper Penny or Designer Copper aluminum | Painted coil; no patina (Gutter Supply) |
| Ice dams are common | 0.032 in to 0.040 in aluminum, or copper | HomeGuide gauge guidance |
| Roof has aluminum or zinc flashing, panels or an awning below the gutter line | Aluminum, or copper only with isolation and rerouted runoff | CDA Table 1.3A and runoff warning |
| You need a specific trim color | Aluminum | 21 colors on one supplier’s coil (Lynch Aluminum) |
A hybrid, with copper on a visible front elevation and aluminum elsewhere, can work if the metals never touch and copper never drains onto aluminum, which is the runoff rule in section 1 of the CDA Design Handbook. If neither fits the budget or the roof, see our rundown of gutter alternatives and when they work before committing.
Copper vs aluminum gutters: frequently asked questions
Are copper gutters worth the extra cost?
Copper gutters can be worth it if you plan to stay 50 years or own a historic home with half-round gutters. HomeGuide puts copper at $15 to $40 per linear foot installed against $6 to $12 for seamless aluminum, but NAHB and InterNACHI rate copper gutters at 50+ years, with soldered joints and no repainting. Over a 10-year hold, aluminum is the cheaper choice.
Do copper gutters last longer than aluminum?
Yes. NAHB and InterNACHI both rate copper gutters at 50+ years, while NAHB puts the aluminum average at 20 years and InterNACHI rates aluminum at 20 to 40+. NAHB rates copper downspouts at 100 years against 30 for aluminum. Copper forms a protective patina and uses soldered seams with no sealant to fail, while aluminum dents more easily.
Can you install copper gutters next to aluminum?
Not directly. The Copper Development Association ranks aluminum lowest in nobility, so copper touching aluminum corrodes the aluminum. Copper gutters need copper, brass, bronze or stainless fasteners, and CDA says copper runoff should not drain onto exposed aluminum. Where the metals must meet, CDA lists bituminous or zinc chromate primers or nonabsorptive tape and gaskets as separators.
Do copper gutters turn green?
Yes, in most climates. Copper gutters darken from bright brown to deeper browns within months, and the Copper Development Association says the blue-green patina takes five to seven years in coastal or industrial air, longer in rural areas, and may never develop in some climates. The CDA guide specification lists paraffin oil or a clear lacquer coat to retard natural weathering.
Which is cheaper, copper or aluminum gutters?
Aluminum is cheaper upfront, at $6 to $12 per linear foot installed for seamless versus $15 to $40 for copper in HomeGuide’s guides. On a cost-per-year basis the two land in the same $0.23 to $0.55 per foot band at published lifespans, so copper only pays off over a multi-decade hold.
What are coppertone aluminum gutters?
Coppertone aluminum gutters are aluminum coil with a copper-colored paint finish, sold under names such as Copper Penny Metallic and Designer Copper. They cost the same as other aluminum gutters, about $6 to $12 per foot installed seamless, and the finish does not weather to brown or green like real copper.
Can you paint copper gutters?
You can, but it is uncommon. Copper is chosen for its bare metal look and natural patina, so painting hides its main advantage and adds a coating that can peel. Aluminum is the better pick if you need a specific color: one coil supplier, Lynch Aluminum, lists 21 baked-on colors.
