Are Metal Roofs Cheaper Than Asphalt Shingles – Decoding Long-Term
No, metal roofs are not cheaper than asphalt shingles in terms of initial installation costs, typically costing 2 to 3 times more upfront. However, metal is significantly cheaper over a 50-year period because it lasts three times longer and requires far less maintenance than traditional shingles.
For DIYers and workshop owners, the choice depends on your budget today versus your desire to never replace the roof again during your lifetime.
Deciding on a new roof for your home or workshop is a massive undertaking that balances immediate budget constraints against long-term durability. You want a structure that protects your tools and family without draining your savings account every fifteen years.
When you start comparing quotes from local suppliers, the first question you’ll likely ask is, are metal roofs cheaper than asphalt shingles for your specific project? It is a common query because the marketing for both materials often focuses on different versions of “value.”
In this guide, I will break down the raw material costs, labor requirements, and the hidden “lifecycle” expenses of both options. By the end, you will know exactly which material fits your DIY capabilities and your long-term financial goals.
Analyzing the Upfront Costs: are metal roofs cheaper than asphalt shingles at the checkout?
If we look strictly at the receipt from the supply house, asphalt shingles win the price battle every single time. Asphalt is the most common roofing material in North America for a reason: it is massively affordable to manufacture and purchase in bulk.
Standard 3-tab shingles or even higher-quality architectural shingles usually cost between $100 and $200 per “square” (a 100-square-foot area). This makes it the go-to choice for homeowners who need a quick, budget-friendly solution for a leaking roof.
Metal roofing, on the other hand, starts at a much higher price point. Even basic corrugated steel panels can cost double what shingles do, and premium standing seam systems can be four times the price.
While many homeowners wonder if are metal roofs cheaper than asphalt shingles, the answer in the short term is a definitive no. You are paying for the specialized manufacturing and the high-grade coatings required to prevent rust and UV damage.
Material Grade Variations
Not all asphalt is created equal, and the same goes for metal. Basic 3-tab shingles are the cheapest, but they are thin and prone to wind damage. Architectural shingles are thicker and offer a better aesthetic profile but cost more.
With metal, you have options like Galvalume, aluminum, and even copper. Aluminum is excellent for coastal areas because it doesn’t rust, but it carries a higher price tag than steel panels.
The gauge of the metal also dictates the price. A thicker 24-gauge steel panel will cost more than a 29-gauge panel but will offer significantly better impact resistance against hail and falling branches.
The Longevity Factor: Why Metal Wins the Long Game
The real secret to understanding roofing costs is looking at the service life of the material. An asphalt roof is essentially a ticking clock, usually lasting between 15 and 25 years depending on your climate.
In areas with high heat or frequent storms, that lifespan can drop even further. You might find yourself paying for a full tear-off and replacement twice in a 40-year period.
Metal roofs are frequently rated for 50 to 70 years. When you calculate the cost per year of service, the question of are metal roofs cheaper than asphalt shingles starts to shift toward the metal side of the scale.
If you plan on staying in your home for several decades, a metal roof is a “one-and-done” investment. You avoid the repeated labor costs and the rising prices of petroleum-based shingles in the future.
Weather Resistance and Durability
Metal is naturally non-combustible, which can be a literal lifesaver in wildfire-prone areas. It also sheds snow and ice much more efficiently than shingles, preventing dangerous ice dams from forming.
Asphalt shingles can “scuff” in high heat or become brittle in extreme cold. Over time, the granules wash away into your gutters, leaving the underlying mat exposed to the sun’s degrading UV rays.
A high-quality metal roof with a Kynar 500 coating will retain its color and structural integrity for decades. This durability reduces the “hidden cost” of storm damage repairs that often plague shingle roofs.
Energy Efficiency and Insurance Savings
One area where metal roofs often pay for themselves is in your monthly utility bill. Metal is highly reflective, meaning it bounces solar radiation away from your home rather than absorbing it.
Asphalt shingles act like a thermal sponge, soaking up heat all day and radiating it into your attic long after the sun goes down. This forces your AC to work harder, increasing your energy consumption.
In the summer months, a “cool” metal roof can reduce cooling costs by as much as 25%. Over twenty years, these savings can bridge the gap between the initial price of metal and shingles.
Furthermore, many insurance companies offer discounts for homes with UL 2218 Class 4 impact-rated metal roofs. Because metal is less likely to leak after a hail storm, the insurer takes on less risk.
Environmental Impact and Sustainability
If you are a DIYer who cares about your carbon footprint, metal is the clear winner. Most metal roofing contains at least 25% recycled content and is 100% recyclable at the end of its life.
Asphalt shingles are a petroleum product. Every year, millions of tons of old shingles end up in landfills, where they take centuries to decompose.
Installing metal means you are contributing to a circular economy. Plus, metal roofs can often be installed directly over existing shingles, saving you the cost and mess of a total tear-off.
DIY Considerations for the Workshop Owner
For the “Jim BoSlice” crowd, the question of are metal roofs cheaper than asphalt shingles often comes down to labor. Can you do the work yourself to save on those high professional installation fees?
Asphalt shingles are relatively DIY-friendly. With a roofing nailer, a chalk line, and a sturdy ladder, a determined homeowner can shingle a simple gable roof over a weekend.
Metal roofing is more technically demanding. Working with large panels requires precision cutting with aviation snips or specialized shears, and you must account for thermal expansion and contraction.
If you mess up the flashing or the fastener tension on a metal roof, you risk significant leaks that are harder to track down than a simple shingle replacement. However, the satisfaction of a permanent metal install is hard to beat.
Tools and Safety Gear
Before you climb onto the roof, you need the right gear. For shingles, you’ll need a pneumatic coil nailer, a hook blade knife, and a roof bracket system for steep pitches.
For metal, you’ll need a high-torque impact driver, metal shears, and potentially a bending brake for custom flashing. Always use a safety harness and a dedicated anchor point regardless of the material.
Metal panels can be incredibly slippery, even when dry. Never attempt a metal roof installation without magnetic specialized footwear or high-traction boots designed for roofing work.
Maintenance and Repair Costs Over Time
Maintenance is the silent budget killer. Asphalt roofs require regular inspections to look for cracked, curled, or missing shingles after every major wind event.
If you have trees overhanging your shop, moss and algae can grow on shingles, holding moisture against the roof deck and causing premature rot. Cleaning shingles requires specialized chemicals and care.
Metal roofs are almost maintenance-free. An occasional wash to remove debris and a quick check of the fastener gaskets every ten years is usually all that is required.
If a metal roof does leak, it is often due to a backed-out screw or a failed sealant at a transition point. These are generally simple, low-cost fixes for a handy DIYer.
Dealing with Potential Noise
A common concern with metal is the noise during rainstorms. While some people love the sound of rain on a tin roof, it can be distracting in a home office or living area.
This is easily mitigated with proper solid decking and high-quality underlayment. In a workshop environment, the noise is rarely an issue, but it is a factor to consider for residential applications.
Asphalt shingles provide natural sound dampening due to their mass and texture. If quiet is your absolute priority, shingles have a slight edge, though modern metal installs are much quieter than old barns.
Comparing the Aesthetics: Curb Appeal vs. Function
In the past, metal roofs were reserved for commercial buildings or rural barns. Today, metal comes in a variety of styles, including some that mimic the look of slate, wood shakes, or even traditional shingles.
Asphalt shingles offer a classic look that fits into almost any neighborhood. They provide a textured, multi-dimensional appearance that many homeowners find visually appealing and “warm.”
However, metal provides a sleek, modern aesthetic that can significantly increase a home’s resale value. Prospective buyers often view a metal roof as a premium upgrade, much like granite countertops.
When you ask are metal roofs cheaper than asphalt shingles, you also have to consider the “value-add” to your property. A home that never needs a new roof is a much easier sell in a competitive market.
Frequently Asked Questions About Roofing Costs
Does a metal roof make my house hotter?
Actually, the opposite is true. Metal reflects solar heat, whereas asphalt shingles absorb it. A metal roof typically keeps your attic and living spaces cooler during the summer months.
Can I install metal over my old asphalt shingles?
In many jurisdictions, yes. This is called a “re-roof.” You will need to install furring strips (lathe) over the shingles to provide a flat surface and an air gap for the metal panels.
How much more does a metal roof cost than shingles?
On average, expect to pay $300 to $900 per square for metal, compared to $100 to $250 per square for asphalt shingles. This varies based on material type and roof complexity.
Is a metal roof more likely to be hit by lightning?
No. While metal is a conductor, lightning is attracted to the highest point, not the material. If hit, a metal roof is safer because it is non-combustible and won’t catch fire.
Do metal roofs rust over time?
Modern metal roofing is treated with zinc (galvanized) or a mix of aluminum and zinc (Galvalume). These coatings, combined with high-performance paint, prevent rust for decades.
Final Verdict: Which Should You Choose?
If you are on a tight budget and need to get a roof over your head today, asphalt shingles are the practical choice. They are cheap, easy to find, and simple to install for a beginner DIYer.
However, if you look at your home as a long-term investment, metal is the superior financial decision. It offers better protection, lower energy bills, and a lifespan that outlasts almost every other building material.
Think about your workshop goals. Do you want to spend your weekends in twenty years tearing off old shingles, or do you want to be inside your shop working on your next project under a roof that is still as good as the day you installed it?
Take the time to measure your roof, price out the materials at your local yard, and be honest about your skill level. Whether you go with the classic shingle or the modern metal panel, doing the job right the first time is the best way to save money.
