Why Choose Decra Metal Shake in Copper?
When homeowners seek a roofing material that combines old-world charm with modern engineering, the Decra Metal Shake in copper stands out as a premium choice. This product replicates the distinctive appearance of hand-split cedar shakes but delivers the resilience of stone-coated steel, with a copper finish that evolves over time. For those prioritizing Decra Metal Shake Shingles: Authentic Look with Metal Durability, the copper variant offers a unique blend of aesthetics and longevity that few other materials can match.
What Makes the Copper Finish Unique on Decra Metal Shake?
The copper finish on Decra Metal Shake is not a simple paint or coating—it’s a proprietary stone-coated surface that uses copper granules embedded in an acrylic resin. Unlike traditional copper roofing, which requires solid copper sheets, Decra’s method gives you the look of copper without the extreme cost or weight. The finish starts as a bright, warm copper tone that gradually patinas to a soft brown-green over several years, depending on local climate and exposure.
This patination process is natural and adds character, but it’s also predictable: in dry climates, the copper stays brighter longer; in humid or coastal areas, the patina develops faster. The stone coating protects the underlying Galvalume steel from corrosion, so the roof’s structural integrity remains intact even as the aesthetic evolves. Homeowners who enjoy a living roof that changes with the seasons often find this feature appealing.
- Initial color: warm copper, consistent across all shakes
- Patina timeline: 2–5 years for visible change, 10–15 years for full maturation
- Coating thickness: 0.5–0.7 mm protective stone layer
How Long Does Copper Decra Metal Shake Last Compared to Standard Copper?
Solid copper roofing can last 50–100 years, but it comes with a high material cost and requires specialized labor for installation. The Decra Metal Shake in copper offers a different value proposition: the Galvalume steel core provides structural durability for 40–60 years, and the copper coating is engineered to maintain its color integrity for at least 30 years before any significant fading. In practice, many installations in moderate climates show the copper finish lasting 35–40 years before needing a recoating.
What sets this apart is the maintenance profile. Solid copper needs periodic cleaning to prevent green stains on nearby surfaces, and it can be damaged by falling branches. The Decra version is more impact-resistant—it’s rated for Class 4 impact resistance (the highest rating per UL 2218)—and doesn’t require the same level of upkeep.

| Aspect | Solid Copper Roofing | Decra Metal Shake Copper |
|---|---|---|
| Lifespan | 50–100 years | 40–60 years |
| Impact resistance | Moderate (Class 2–3) | Class 4 (highest) |
| Weight per square foot | 1.5–2.5 lbs | 1.3–1.5 lbs |
| Color evolution | Natural patina, varies | Controlled patina process |
| Cost per square (100 sq ft) | £1,500–£3,000 | £800–£1,400 |
Does Copper Decra Metal Shake Require Special Installation?
Installation of Decra Metal Shake in copper follows the same basic procedure as other Decra products, but there are a few nuances worth noting. Because copper is a softer metal than steel, the shake panels need careful handling during installation to avoid scratching or denting. The manufacturer recommends using rubber-soled shoes on the roof and avoiding dragging panels across existing coverage.
The interlocking system is standard—each shake overlaps the one below it, and the panels are fastened with corrosion-resistant screws into the roof deck. The recommended fastener spacing is 12 inches on center along the battens, with additional screws at the eaves and ridges. The copper finish does not require any sealant or caulk on the visible surface, as the interlocking design sheds water naturally.
For those new to metal roofing, consulting Installing Decra Metal Shake: What to Expect provides a step-by-step guide, including underlayment requirements and flashing details. The copper variant may also need a slightly larger expansion gap at the eaves—about 1/8 inch more than standard—because copper expands and contracts slightly more than steel in temperature swings.
- Labor hours per square: 4–6 hours for experienced crew
- Special tools: shear cutter, rubber mallet, screw gun with depth stop
- Underlayment: high-temp synthetic felt (mandatory for copper finish)
How Does the Cost of Copper Decra Metal Shake Compare to Other Premium Roofing?
Pricing for Decra Metal Shake in copper typically ranges from £800 to £1,400 per square (100 square feet), including materials and basic installation. This is roughly 30–50% less than solid copper roofing, which runs £1,500–£3,000 per square, but about 20–30% more than standard Decra Metal Shake in other colors like charcoal or bronze. The premium over standard colors reflects the specialty copper pigment and the additional quality control in the coating process.
When you factor in the longer lifespan compared to asphalt shingles (15–20 years), the copper Decra option becomes cost-effective over time. Asphalt shingles cost £300–£500 per square but need replacement three times as often. Over a 60-year period, the Decra copper roof costs about 40% less than repeated asphalt replacements, assuming inflation-adjusted pricing.

What Maintenance Does a Copper Decra Metal Shake Roof Need?
One of the biggest selling points of Decra Metal Shake in copper is low maintenance. Unlike solid copper, which requires periodic acid cleaning to maintain a uniform patina, the Decra version is self-maintaining. The stone coating prevents the copper from staining adjacent surfaces, so you don’t get the green runoff that often plagues solid copper roofs on gutters and walkways.
Routine maintenance involves:
- Annual inspection for loose fasteners or chipped coatings
- Clearing debris from valleys and gutters twice a year
- Trimming overhanging branches to reduce lichen growth
If a stone chip exposes bare metal, touch-up paint is available from Decra, but it’s rarely needed unless a branch falls on the roof. The Class 4 impact rating means most hailstones bounce off without leaving dents. For coastal homeowners, the copper finish has better resistance to salt spray than standard colored coatings, but it still benefits from a freshwater rinse after severe storms.
What Owners Say About Decra Metal Shake in Copper
Homeowners who have installed Decra Metal Shake in copper often point to the aesthetic appreciation over time. “We chose the copper finish because we wanted something that felt timeless,” says a homeowner in Kent who installed it three years ago. “After two winters, the color is already shifting to a warm brown, and it looks exactly like the old copper roofs you see in historic villages.”
Another owner in Devon notes the practical benefits: “I was worried about the patina staining our white gutters, but there’s been no discoloration at all. The cleaning is minimal—just a hose-down once a year.” However, some owners mention that the initial copper color is brighter than they expected. “The sample looked accurate, but the full roof is definitely more vivid. It took about 18 months to mellow out,” reports a homeowner in Cornwall. Overall, satisfaction ratings are high, with most owners citing the unique appearance and low upkeep as the top advantages.
Frequently Asked Questions
- Is Decra Metal Shake in copper more expensive than standard colors? Yes, typically 20–30% more than finishes like charcoal or bronze, due to the copper pigment cost and quality control in the coating process.
- Does the copper finish need protective sealing? No—the stone coating and acrylic resin provide adequate protection. Sealing is not required and could interfere with the natural patina process.
- How long does the copper color last before patina changes? Visible patina typically begins in 2–3 years, with full color maturation occurring over 10–15 years, depending on sun and humidity exposure.
- Can I install Decra Metal Shake copper over an existing asphalt roof? Yes, but only if the deck is sound and meets load requirements. Most installations use a tear-off and new underlayment for best results.
- Does the copper finish void the warranty if it changes color? No—color change due to natural patina is considered normal aging and is covered under the aesthetic durability clause for at least 30 years.
- What is the wind rating for copper Decra Metal Shake? The product is tested to withstand winds up to 120 mph (190 km/h), with installation following manufacturer guidelines for high-wind zones.
