Copper gutters cost roughly $18 to $40 per linear foot installed and last 50 to 100 years, while aluminum gutters run about $8 to $14 per linear foot installed and last 20 to 30 years. Copper wins on lifespan, corrosion resistance, and curb appeal. Aluminum wins on upfront price and color choice. For most single-family homes the deciding factors are budget, how long you plan to own the house, and whether the gutters will touch other metals on the roof.
Copper vs aluminum gutters: side-by-side comparison
The table below compares the two materials on the factors that actually move a buying decision. Figures reflect 2026 U.S. pricing for standard 5-inch and 6-inch profiles and vary by region, profile, and whether the run is seamless or sectional.
| Factor | Copper gutters | Aluminum gutters |
|---|---|---|
| Installed cost (per linear foot) | $18 to $40 | $8 to $14 |
| Typical lifespan | 50 to 100 years | 20 to 30 years |
| Material thickness | 16 oz to 20 oz sheet | 0.027 in to 0.032 in |
| Corrosion resistance | Excellent, self-protecting patina | Good, but corrodes at cut edges |
| Joint method | Soldered (watertight) | Sealed, riveted, or seamless |
| Color options | Bare metal, ages to green patina | Paintable, 25-plus factory colors |
| Dent and impact resistance | High (about 40% higher tensile strength) | Lower, dents from ladders and ice |
| Maintenance | Annual cleaning, no repainting | Cleaning plus repaint every 10 to 15 years |
| Recyclable | Yes, high scrap value | Yes |
| Best for | Historic homes, long-term owners, half-round runs | Budget builds, rentals, color matching |
What are copper gutters?
Copper gutters are troughs formed from solid copper sheet, usually 16 oz or 20 oz weight, with joints soldered rather than sealed with caulk. Copper does not rust. Instead it forms a protective patina that shifts from bright penny-brown to brown to blue-green over 6 months to several years, and that oxide layer shields the metal underneath. Copper is common in half-round profiles on historic and high-end homes because the material and the soldered seams can outlast the roof itself.
What are aluminum gutters?
Aluminum gutters are lightweight troughs roll-formed from coated aluminum coil, most often 0.027-inch or thicker 0.032-inch stock. They are the most installed residential gutter in the United States because they are inexpensive, will not rust, come in dozens of baked-on colors, and can be run seamless from a truck-mounted machine. The trade-offs are lower dent resistance and a shorter service life, since aluminum can corrode at cut edges and its finish fades over decades.
How much do copper and aluminum gutters cost?
Aluminum is the budget pick and copper is the premium pick, with copper typically costing two to four times more installed. Aluminum runs about $8 to $14 per linear foot installed, while copper runs about $18 to $40 per linear foot depending on profile, gauge, and the amount of soldering the job requires.
On a typical 150 to 200 linear foot house, that puts a full aluminum system near $1,200 to $2,800 and a copper system near $2,700 to $8,000 installed. Half-round copper and heavier 20 oz stock sit at the top of that range. 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 expected lifespan gives a rough annual figure. This is a Roofing Brief calculation using the ranges above, not a quoted price.
- Aluminum: about $11 per linear foot installed over 25 years is roughly $0.44 per foot per year.
- Copper: about $28 per linear foot installed over 75 years is roughly $0.37 per foot per year.
On a strict cost-per-year basis copper can come out ahead, but only if you or later owners keep the house long enough to bank the extra decades. Over a 10-year hold, aluminum is almost always the cheaper choice.
Which lasts longer and holds up better?
Copper lasts longer in nearly every climate. A soldered copper system commonly reaches 50 to 100 years, while aluminum typically reaches 20 to 30 years before edge corrosion, finish failure, or dents force replacement. Copper carries roughly 40% higher tensile strength than aluminum, so it resists ladder dents, ice-dam pressure, and falling-limb impact better.
Aluminum still performs well for the money. It will not rust, handles freeze-thaw cycles, and in a mild climate a well-installed 0.032-inch system can push past 30 years. 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, which is a large part of why it lasts.
Installation differences that affect cost and longevity
Installation method is where these two diverge most. Aluminum is usually run seamless on site, so a long run has few joints. Copper is cut and soldered by hand, which takes skill and drives labor cost, but produces watertight seams with no caulk to degrade.
- Confirm the profile. Aluminum favors K-style; copper is common in both K-style and half-round. Compare shapes in our gutter dimensions spec sheet.
- Choose seamless or sectional. Aluminum can be extruded seamless on site, which cuts leak points. See how that works in our seamless gutter systems guide.
- Match the hangers and fasteners to the metal. Copper needs copper or stainless hangers and screws to avoid galvanic corrosion.
- Hire for soldering skill on copper. A cold or sloppy solder joint is the most common copper failure point, so verify the crew solders rather than seals.
The mixed-metal problem most guides skip
Copper cannot safely touch aluminum, bare steel, or galvanized metal, because the two dissimilar metals set up galvanic corrosion that eats the less-noble metal. This is the detail that trips up homeowners who try to mix a copper accent with existing aluminum, and most comparison articles never mention it.
Two practical consequences follow. First, copper gutters must use copper or stainless steel fasteners, hangers, and downspout straps, never aluminum or plain steel. Second, copper runoff carries dissolved metal that can stain and slowly corrode aluminum, zinc, or galvanized surfaces below it, so a copper gutter draining onto an aluminum roof or a steel awning is a poor pairing. Aluminum gutters have the mirror caution near copper flashing or copper roofing. When metals must meet, isolate them with a non-conductive barrier or route water so it does not run metal-to-metal.
Which gutter should you choose?
Use this decision framework rather than a single winner, since the right answer depends on budget, hold time, and the look you want.
- Choose copper if you own a historic or high-value home, plan to stay 15-plus years, want a soldered system that may outlast the roof, or you are running half-round gutters where copper is the classic match.
- Choose aluminum if you need the lowest upfront cost, want a specific paint color to match trim, are outfitting a rental or a home you may sell within a decade, or you want a fast seamless install.
- Consider a hybrid only with care: copper on a visible front elevation and aluminum elsewhere can work, but keep the metals physically separated and never let copper drain onto aluminum.
- Weigh resale. Copper can lift curb appeal on a home where buyers expect premium materials, but on a mid-market house the premium may not return at sale.
If neither fits the budget or the roof, gutterless options exist too. See our rundown of gutter alternatives and when they work before committing.
