Gutter Materials: Why Steel and Copper Outperform Aluminum

Get It Done Right the First Time

Choosing the right gutter materials can make the difference between a system that lasts decades and one that fails after a few harsh Minnesota winters. If you’re thinking about new gutters or replacing ones that didn’t hold up, this is where the decision really matters.

At Sheridan Sheet Metal, we fabricate and install gutters built for Minnesota weather. No shortcuts, no thin materials, no guesswork.

Comparing Gutter Materials for Minnesota Homes

Most homeowners, and even some contractors, start with one question: “What’s the cheapest option?”

That’s usually aluminum.

But the better question is:
“What’s going to perform for the next 20–30 years without failing?”

Because gutters aren’t just trim, they protect your roof, fascia, foundation, and everything below.

At Sheridan, we work with three primary gutter materials:

• Aluminum (most common, but often overused)
• Steel (our go-to recommendation)
• Copper (a premium, long-term solution)

Here’s how they actually compare in the real world.

Steel vs Aluminum Gutters

Minnesota isn’t easy on gutters. Snow load, ice, ladders, branches. It all adds up.

Steel gutters are built for that environment.

• Higher tensile strength than aluminum
• Significantly more resistant to bending and deformation
• Holds its shape through freeze-thaw cycles

Aluminum gutters, on the other hand:

• Dent easily
• Warp over time
• Commonly show damage after just a few seasons

Copper performs well long-term but is softer, meaning it can still take impact damage, especially from ladders or debris.

Bottom line: If you want gutters that stay straight and functional, steel is the clear winner.

Impact Resistance: Steel vs Aluminum Gutters

This is where most gutter systems fail early.

Real-world conditions:

• Hail
• Falling branches
• Ladder contact
• Ice buildup

Aluminum dents. Easily.
Once that happens, water flow can be compromised and the system starts to fail.

Steel resists impact.
That means:

• Fewer repairs
• Better performance
• Longer lifespan

For contractors, this also means fewer callbacks.

Copper Gutters vs Steel Gutters

Gutters are highly visible especially on modern homes.

Copper Gutters

• Start bright, age into a natural patina
• High-end architectural look
• Ideal for custom homes and historic properties

Steel Gutters

• Clean, consistent finish
• Holds color over time
• Doesn’t chalk or fade like aluminum

Aluminum Gutters

• Wide color options upfront
• More prone to fading and wear
• Often looks aged before its time

If curb appeal matters, steel and copper both outperform aluminum in different ways.

Coating Matters: Why Our Steel Gutters Last Longer

Not all steel gutters are created equal.

At Sheridan, we use full double-sided coated steel, not the standard “wash coat” you’ll find inside cheaper systems.

Why that matters:

• Interior coating protects against constant water exposure
• Exterior coating resists UV and weather
• Prevents premature rust and breakdown

This is one of the biggest differences between:

• A gutter system that lasts 10–15 years
• And one that performs for several decades

Maintenance & Lifespan

Let’s talk real expectations:

Steel Gutters

• 20–30+ year lifespan
• Minimal maintenance when properly installed
• Strong performance in harsh climates

Copper Gutters

• 40-50+ years
• Virtually maintenance-free
• Premium investment

Aluminum Gutters

• Shorter lifespan
• More frequent repairs and replacements
• Higher long-term cost than most people expect

Best Gutter Materials for Long-Term Performance

Yes, aluminum is cheaper upfront.

But here’s what usually happens:

• Repairs start early
• Sections get replaced
• Performance declines
• Full replacement comes sooner than expected

Steel hits the sweet spot:

• Moderate upfront investment
• Significantly longer lifespan
• Lower total cost over time

Copper is a premium choice, but for the right home, it’s a one-time investment.

For Contractors: How to Sell the Upgrade

If you’re a roofer or builder, this is an easy win with homeowners.

Position it like this:

• “We can install aluminum, but here’s why we don’t recommend it”
• Show real-world denting and failure examples
• Offer steel as the long-term solution

Homeowners understand value when it’s explained clearly.

And when the system performs, it reflects back on your work.

Common Gutter Myths (That Cost People Money)

“All gutters are basically the same.”
They’re not. Material thickness, coating, and fabrication make a huge difference.

“Aluminum is good enough.”
Sometimes, but not in high-stress environments like Minnesota.

“Copper is just for looks.”
Copper is one of the longest-lasting materials available.

What We Recommend at Sheridan Sheet Metal

For most homes:
– Steel gutters are the best overall investment

For high-end or architectural projects:
– Copper is unmatched

For short-term or budget-driven installs:
– Aluminum may work, but it comes with tradeoffs

Final Takeaway

If you’re going to replace your gutters, do it once and do it right.

The material you choose directly impacts:

• How long your system lasts
• How well it protects your home
• How much you’ll spend over time

At Sheridan Sheet Metal, we don’t install systems we know will fail early. We build and install gutters that hold up season after season.
