Metal roofs cost more upfront but last longer, so the total cost over time depends on how long you stay in the house

A metal roof typically costs between $8 and $15 per square foot installed, while asphalt shingles run $3 to $5 per square foot. On a 2,000-square-foot roof, that means metal could cost $16,000 to $30,000 versus $6,000 to $10,000 for shingles — a difference of $10,000 to $20,000 upfront. But metal roofs last 40 to 70 years, while shingles last 15 to 25 years. If you plan to stay in the house long enough to avoid replacing shingles twice, metal becomes cheaper over time.

The actual price you pay depends on the metal type (aluminum, steel, or copper), your roof's pitch and complexity, local labor rates, and whether you need structural reinforcement. Copper is the most expensive; aluminum and steel are closer to each other. A straightforward, low-pitch roof costs less to install than a steep or heavily angled one, regardless of material.

Key Takeaways

  • Metal roofs cost two to four times more to install than asphalt shingles, but they last three times longer.
  • The break-even point is usually between 20 and 30 years — if you plan to stay that long, metal becomes the cheaper choice over the roof's lifetime.
  • Metal roofs may reduce cooling costs in hot climates and may have access to for some insurance discounts, which can offset part of the higher upfront cost.
  • Shingles are cheaper to replace when damage occurs, but metal roofs rarely need replacement and have lower maintenance costs overall.
  • Installation quality matters more with metal than shingles — poor installation can lead to leaks and rust, so contractor experience is worth the cost.

How long each roof lasts and what that means for total cost

Asphalt shingles typically need replacement every 15 to 25 years, depending on climate and maintenance. In hot, sunny regions they degrade faster; in cooler areas they last longer. Metal roofs last 40 to 70 years with minimal maintenance — some manufacturers warranty them for 50 years. That means a homeowner who stays 30 years will replace shingles once and pay for two installations, while a metal roof requires only one.

To compare true cost, add the price of replacement. If shingles cost $8,000 to install and need replacement in 20 years, you pay $16,000 total over 40 years (plus inflation). A metal roof costing $20,000 upfront and lasting 50 years costs $20,000 total. The longer you stay, the more metal saves. If you plan to sell in 10 years, shingles are cheaper; if you plan to stay 25 years or more, metal usually wins.

What affects the price of each material

Metal roof cost varies by the type of metal. Aluminum and steel cost roughly the same — $8 to $12 per square foot installed. Copper costs $15 to $25 per square foot and lasts even longer (60 to 100 years), but few homeowners choose it for residential roofs because of the price. Standing seam metal (panels that run vertically) costs more than metal shingles (which look like traditional shingles) because standing seam requires more precision installation.

Asphalt shingle cost depends mainly on grade. Three-tab shingles (the cheapest) run $3 to $5 per square foot. Architectural or laminated shingles (thicker, more durable-looking) run $5 to $8 per square foot. Both are installed the same way, so labor cost is similar. The main variable is how many shingles you need and how complex your roof shape is.

Installation labor is often the largest cost difference. Metal roofs require more skill to install correctly — improper sealing or fastening causes leaks and rust. Shingle installation is more standardized, so labor rates are lower and more contractors can do it. In areas where few roofers work with metal, you may pay a premium for the informed.

Maintenance costs and what can go wrong

Asphalt shingles need regular maintenance to last their full lifespan. You should have the roof inspected every 3 to 5 years, clear debris from gutters and valleys, and replace individual damaged shingles as they crack or curl. A single shingle replacement costs $100 to $300. Moss or algae growth in damp climates may require cleaning. Over 20 years, maintenance can add $500 to $2,000 depending on climate and how often problems occur.

Metal roofs need less maintenance but require different care. You should inspect seams and fasteners every 5 to 10 years, clear debris, and check for rust (especially at cut edges or where two panels meet). Rust can be treated with a brush-on coating if caught early. Dents from hail or falling branches are cosmetic and do not affect function, though they may bother you visually. Maintenance costs are usually $200 to $500 over the roof's life, much lower than shingles.

Repair costs differ sharply. A shingle leak might require replacing a section of shingles ($300 to $800). A metal roof leak usually requires resealing a seam or fastener ($100 to $400). Metal roofs are less likely to leak overall, so you may never need a repair. Shingles are more prone to leaks as they age, especially around flashing and valleys.

Energy savings and insurance discounts

Metal roofs reflect sunlight better than dark shingles, which can reduce cooling costs in hot climates. Studies show energy savings of 10 to 25 percent in air-conditioned homes in hot regions, though savings are smaller in cooler climates or if your roof is shaded by trees. The savings depend on your local electricity rates and how much you run air conditioning. In a hot climate with high cooling costs, metal could save $200 to $400 per year, which adds up over decades.

Some insurance companies offer discounts for metal roofs because they are more fire-resistant and less likely to leak. Discounts range from 5 to 15 percent of your annual premium, depending on the insurer and your location. In areas prone to hail or wildfires, the discount may be larger. Ask your insurance company what discount they offer before deciding — it can offset $500 to $1,500 of the upfront cost over time.

When shingles make more sense financially

If you plan to sell the house within 10 to 15 years, shingles are almost always the cheaper choice. You pay less upfront, and you will not need replacement before you leave. A new roof (of either type) adds value at resale, but buyers do not typically pay extra for a metal roof that costs twice as much — they pay for a roof that works. So if you are financing the roof through a mortgage, shingles lower your monthly payment.

Shingles also make sense if your roof is in poor condition and needs replacement soon. Replacing shingles now and metal in 20 years spreads the cost across two decades. If you replace with metal now, you commit to a large expense upfront even if you might move before the payoff period.

In regions where metal roofs are uncommon, finding a may have access to installer can be difficult and expensive. If local roofers have little metal experience, labor costs rise and quality risk increases. In that case, shingles may be the practical choice straightforward because the infrastructure exists to support them.

Financing and resale value

A metal roof adds to your home's resale value, but not dollar-for-dollar with its cost. Buyers see it as a long-term benefit (no replacement needed for decades), but they do not typically pay an extra $15,000 for a roof that cost $20,000 to install. Most appraisers add 1 to 5 percent to home value for a metal roof, depending on the market. In a $300,000 home, that might be $3,000 to $15,000 — less than the cost difference between metal and shingles.

If you are financing the roof, a metal roof increases your monthly payment significantly. A $15,000 metal roof financed over 15 years at 7 percent interest costs roughly $140 per month. Shingles at $8,000 cost roughly $75 per month. That $65 monthly difference matters if you are on a tight budget, even if metal saves money over 30 years.

Frequently Asked Questions

Do metal roofs really last 50 years?

Most metal roofs last 40 to 70 years with normal maintenance. The exact lifespan depends on the metal type, climate, and installation quality. Aluminum and steel roofs in moderate climates typically reach 50 years. Coastal areas with salt air may shorten lifespan due to rust. Check the manufacturer's warranty — most offer 30 to 50 year coverage.

Will a metal roof make my house cooler?

Metal roofs reflect more sunlight than dark shingles, which can reduce cooling costs by 10 to 25 percent in hot climates. The savings depend on your roof color (lighter colors reflect more), how much sun your roof gets, and your local electricity rates. In cooler climates or shaded roofs, savings are minimal. Energy savings alone rarely justify the upfront cost difference, but they help offset it over time.

Can I install a metal roof over my existing shingles?

Yes, in most cases. Installing metal over shingles costs less than removing shingles first, though it adds weight to your roof structure. Check with a local roofer and your building department — some areas require shingle removal, and some roof structures cannot support the added weight. Removal adds $1,000 to $3,000 to the project but ensures better long-term performance.

What happens to a metal roof in a hailstorm?

Metal roofs dent in large hail but rarely leak from hail damage alone. Dents are cosmetic and do not affect the roof's function. Shingles are more likely to crack or lose granules in hail, which can lead to leaks. If hail damage bothers you visually, you can have dents repaired, though the cost ($500 to $2,000) may not be worth it for cosmetic damage.

Is metal noisier than shingles when it rains?

Modern metal roofs with proper insulation and attic ventilation are not noticeably noisier than shingles. Older metal roofs or those installed directly over rafters without insulation can sound louder. Ask your installer about sound dampening — most modern installations include it as standard. If noise is a concern, discuss it with your roofer before installation.
