What drives copper pricing
Profile: half-round copper costs more than K-style. Gauge: 16 oz is standard; 20 oz costs more and lasts longer. Fittings: ornamental leaderheads, custom miters, and copper downspouts add up fast. Commodity price: copper is a traded metal — quotes move with the market, unlike aluminum. Craft: copper is soldered, not sealed with caulk, so it takes a genuinely skilled installer.
The patina question
New copper is bright; within a year it darkens to bronze; over roughly 10–20 years of NJ weather it develops the classic green patina. That layer protects the metal underneath — it's why copper outlives everything else. If you want lasting shine, a clear sealer can hold it back for a few years, but it needs re-application and most owners eventually let it patina.
Where copper actually pays off in New Jersey
Historic districts and estate properties — think Saddle River, Short Hills, Mendham, Montclair's Victorians, Morristown's older colonials. On these homes copper is often the architecturally correct choice, and buyers notice. Aluminum on a slate-roofed 1890s home looks exactly as wrong as it sounds.
One warning
Never let copper contact aluminum or galvanized steel directly — dissimilar metals in contact with rainwater cause galvanic corrosion that eats the lesser metal. A proper copper job uses copper hangers, copper downspouts, and copper or stainless fasteners throughout. If a bid mixes metals, that installer doesn't know copper.

FAQ
How much do copper gutters cost in NJ?
Installed copper gutters run about $25–$45 per linear foot in New Jersey, or roughly $5,000–$11,000 for a typical single-family home — about 3–4x the cost of aluminum. Half-round copper and ornate leaderheads push the top end higher.
How long do copper gutters last?
Copper gutters commonly last 50–100 years, versus 20–30 for aluminum. Many century-old New Jersey homes still have their original copper. On a long time horizon the annualized cost is competitive with aluminum.
Do copper gutters turn green?
Yes. Copper oxidizes from bright penny-brown to dark brown, then to a green patina over roughly 10–20 years depending on exposure. The patina is protective, not damage. If you want to keep the shine, it must be sealed and periodically re-treated.
Are copper gutters worth it?
They make sense on historic, high-value, or architecturally significant homes — common in towns like Saddle River, Short Hills, Mendham, and Montclair — where lifespan, appearance, and resale value justify the premium. On an average home you plan to sell in under a decade, aluminum is the smarter buy.
