Metal Roofing: is it Really Worth It in Wisconsin?

Metal roofing is having a moment.

It's trendy and advertised as ultra-durable. You may have seen it featured on new builds or remodels in Wisconsin, and you’ve certainly seen it plastered all over social media. So when homeowners ask us, 'Do you install metal roofs?' we understand why.

But the honest answer is: no, we don’t.

At Sun Vault Roofing, we believe in offering roofing systems that provide the best value, performance, and fit for most Wisconsin homes. That’s why we specialize in premium asphalt roofing and integrated solar shingle solutions.

In this blog, we’ll break down the pros and cons of metal vs asphalt roofs, explain why metal roofing is often oversold, and help you determine what roofing system truly delivers the best return on your investment. We’re not here to bash metal roofing. It has its place! But for most homes in Wisconsin, it’s not the smartest investment, and at Sun Vault Roofing, we don't try to upsell you something that doesn’t make financial sense.

Metal vs. Asphalt Roof Costs over time

Let’s run the numbers. Metal roofs are durable, can look sharp, and may last a long time. But they just don’t make financial sense for most Wisconsin homeowners.

Let’s compare two hypothetical options:

Roof Type	Cost	Lifespan
Asphalt	$20k	30 years
Metal	$45k	70 years

At first glance, a metal roof seems like a “buy it once” solution. But here’s the catch: a metal roof usually costs more than twice as much up front.

Now imagine you stayed in your home for 70 years. You might need two or three asphalt roofs during that time, which could total around $47,000 over the decades. That’s just a little more than the one-time cost of a metal roof.

So is metal the better deal? Sorry. Still no.

Because when you spread those asphalt replacement costs out over 60+ years, they’re way less painful. A roof you pay for in 2055 costs a lot less in today’s dollars than one you pay for right now. In economics, this is called the time value of money, and it makes a big difference.

We even ran the math (see our chart below). Once you factor in inflation and basic economics, asphalt comes out ahead. That’s why at Sun Vault Roofing, we stick with what makes the most sense for our customers: high-quality asphalt roofing that’s affordable, proven, and built to last.

Over 70 years, asphalt roofs cost less than metal roofs, even after multiple replacements. This is because money is worth more right now than in several decades.

Asphalt roofs have a predictable lifecycle in Wisconsin, which makes it easy to plan ahead for maintenance or replacement costs instead of shelling out one large sum upfront for a 70-year metal roof.

Metal Roofs Require Snow Guards, Increasing their Cost

There’s another cold reality homeowners often overlook with metal roofs.

They’re slick . . . dangerously slick.

Because they are so slippery, snow and ice can build up and then slide off in heavy sheets without warning, flattening whatever (or whomever) is below. That’s why most metal roofs in Wisconsin need snow guards or snow rail systems to prevent sudden avalanches.

These usually aren’t optional. Without them, snow sliding off your roof can damage landscaping, crush gutters, or injure someone you care about. Even with guards installed, they’re not foolproof. Poorly-installed systems or cheap materials can still fail, putting more than your wallet at risk.

Snow management systems also add to the already steep price tag of a metal roof. Depending on your setup:

• Individual snow guards can run up to $15 per piece. And you may need dozens or hundreds.

• Bar or rail-style snow retention systems can cost up to $40 per linear foot

  
  

For many homes, that’s an extra $2,000 to $8,000, just to make your already-pricey metal roof as safe as a standard asphalt roof.

Asphalt roofs handle snow differently. Shingles are textured, high-friction, and designed to slow snow movement naturally. Snow retention is built right into the product, with no expensive add-ons required. It’s another reason why asphalt makes more sense for most Wisconsin homes.

Metal Roofs: What You’ve Heard (and What to Know)

Yes, metal roofs can last 40–70 years.

That’s the headline that grabs attention. But there’s a lot homeowners don’t hear upfront. There are a few caveats we think you should know.

Metal roof sticker shock is real.

Metal roofing costs 2–3 times more than a high-quality asphalt system. That’s not a small difference. It’s tens of thousands of dollars more, upfront.

A Metal Roof Might Outlast Your Time in the Home

Sure, a metal roof may last 70 years . . . but will you be in your house that long?

Most people move or refinance before then, meaning you may never fully benefit from that lifespan.

Not All Metal Roofs Are Created Equal

There are two main types of metal roofs:

• Standing seam (great, but expensive)

• Metal Panel / R-panel (cheaper, but prone to leaks)

If a metal roof quote comes in at a price that is close to your asphalt quote, it’s almost certainly an R-panel. These have exposed fasteners which are prone to rust and leaking. We strongly recommend avoiding these for residential homes in Wisconsin.

Installation Is Specialized (and Easy to Mess Up)

Metal roof systems require special equipment and training. When done right, they perform well. But poor installation can lead to:

• Leaks at seams

• Noise from rain and thermal expansion

• Costly fixes down the road

Metal Roofs Dent . . . Easily

Metal roofs are tough, but they're not immune to impact damage.

Hail, acorns, and other falling debris can leave visible dents and dings, even high-end standing seam metal roofs. Those impacts chip away at protective coatings, leaving bare metal exposed to the elements and vulnerable to rust or corrosion.

In fact, metal roofs are vulnerable to hail stones of much smaller sizes than typical Class 3 asphalt shingles (the basic quality used by most reputable asphalt roofers). Class 3 shingles must withstand 20-foot drops from 1.75-inch steel balls. But hail stones as small as ¾ inches in diameter can dent metal roofs.

Because southern Wisconsin regularly sees hail in the ¾-inch range, even premium metal roofs can pick up visible dents from storms that would leave most high-quality asphalt roofs unscathed.

Let's not forget that while it's hailing outside, you are probably seeking refuge inside. And if "inside" for you means a home covered in metal, congratulations! You've just procured free, front-row seats to the UW Badgers percussion drumline.

Best of luck sleeping through that.

Yes, Metal Roofs Can Rust

Even steel roofs with protective coatings can develop rust in 10–20 years, especially if they’re not maintained or installed perfectly.

Dented metal roofs are at even higher risk. Impacts from hail or debris can break through protective coatings, exposing the raw metal underneath. Those dents also create shallow low spots where water can collect. Standing water is the enemy of all roof types. It accelerates rust and wear.

Once rust takes hold, it weakens the roof and can eventually lead to leaks. That’s a big reason we don’t recommend metal roofs for storm-prone areas like southern Wisconsin.

Metal Roofing Warranties Often Look Better Than They Are

Many metal roof warranties are prorated and may not cover:

• Cosmetic damage (fading, dents, rust)

• Improper installation (which is common)

It’s worth reading the fine print before committing to a metal roof, especially if you live in a storm-prone area of Wisconsin where hail and debris damage is common.

Metal Roofs are Not Necessarily More Sustainable than Asphalt Roofs

Metal roofs are easy to recycle and sometimes made from recycled material. And yes, replacing them less often reduces waste and material footprints.

But asphalt shingles are recyclable too! Dane County recycles old shingles, turning them into pavement for local roads. Asphalt shingles are the number 1 recycled material in Dane County and in the United States.

Plus, in Wisconsin the energy savings don’t always pencil out. Reflective metal roofs can actually increase heating costs in winter, which outweighs any cooling benefit. Though this is only likely to be a problem if you lack proper insulation or ventilation. In temperate regions like Wisconsin, as long as your attic is properly insulated and ventilated, your roof color and material don't typically impact your annual energy usage.

Asphalt shingles are the most cost-effective and reliable roofing material for Wisconsin homes

Here's why:

• Excellent value: Modern asphalt roofs last 20–30+ years at a fraction of the cost of metal. Thanks to technological innovations, standard manufacturer product warranties have recently increased to 50 years suggesting that this newer generation of technology will last even longer.

• Aesthetic variety: Options like architectural and designer shingles offer curb appeal and enhanced durability without metal’s industrial look.

• High performance: Asphalt performs well against snow and temperature swings, especially in the cold-to-temperate climate of Wisconsin. They are resistant to larger hail sizes than metal roofs.

• Easier repairs and better warranties: Easier to patch and widely supported by major manufacturers like CertainTeed.

• Domestic manufacturing: because most asphalt shingles are manufactured here in the USA, they are less exposed to price and availability fluctuations than metal which is often imported (and therefore subject to tariffs).

• Quieter: No rain ping or expansion noise.

At Sun Vault Roofing, we install CertainTeed asphalt roofing systems backed by their SureStart™ PLUS warranty, offering up to 50 years of non-prorated coverage.

What About Solar Compatibility?

Many homeowners exploring metal are also interested in solar energy. But here’s the catch: most solar products don’t mount easily on metal without specialized hardware. This adds complexity, cost, and potential for roof penetration issues.

Instead, we recommend CertainTeed Solstice Shingles, a sleek, integrated system that replaces a portion of your asphalt shingles with solar-generating ones. Beautiful aesthetics, lower maintenance.

Still Curious About Metal Roofing?

We get it. Metal roofing has its place and in certain cases (e.g., barns, cabins, rural outbuildings, some businesses), it may make sense. But if you’re a Wisconsin homeowner looking for real-world performance, flexible styling, and a smart long-term investment, asphalt (or solar + asphalt) is likely your best choice.
