How Long Does a Metal Roof Last Compared to Asphalt Shingles?

March 28, 2025

When it comes to choosing a roofing material, longevity is one of the most important factors to consider. Investing in a roof is a significant expense, so understanding how long it will last can help you make a more informed decision and save money in the long run. Among the most popular options, metal roofs and asphalt shingles offer two very different lifespans, maintenance requirements, and aesthetic appeals.

This article compares the durability of metal roofs and asphalt shingles, looking at factors like lifespan, required upkeep, environmental considerations, and cost-effectiveness. Whether you’re building a new home or replacing an old roof, you’ll find all the insights you need here.

The Lifespan of Metal Roofs vs. Asphalt Shingles

Metal Roofs

Metal roofs are renowned for their durability and exceptional lifespan. Most metal roofing systems have a lifespan ranging from 40 to 70 years, depending on the material and installation quality. Some premium materials, such as copper or zinc, can last over a century if properly maintained.

The longevity of metal roofs is largely due to their resistance to environmental stressors, including:

  • Weather Resistance: Metal roofs can withstand high winds, heavy rain, and even hail. They are also fire-resistant, adding an extra layer of safety.
  • Corrosion Resistance (for treated metals): Steel roofs are often coated with protective layers of galvanization and paint to prevent rust and corrosion.

Key Considerations for Metal Roofing Longevity:

  • Material Selection: Aluminum and copper materials are naturally resistant to corrosion, while steel requires protective coatings like galvanization.
  • Proper Installation: A poorly installed roof may allow for water leaks, which can lead to structural issues over time.
  • Maintenance: While minimal, routine inspections and addressing minor damage promptly extend the roof’s lifespan.

Asphalt Shingles

On the other hand, asphalt shingles are the most common roofing material in residential construction, mostly due to their affordability and ease of installation. However, asphalt shingles typically last 15 to 30 years, depending on the type and quality of the shingles.

These shingles aren’t as resistant to weather damage as metal roofs, leading to a shorter lifespan. Harsh environmental conditions, such as extreme heat, heavy snowfall, or storms, can significantly shorten their durability. Asphalt shingles are also more prone to algae growth, curling, or cracking over time.

Key Considerations for Asphalt Roofing Longevity:

  • Shingle Quality: Architectural shingles tend to last longer (20–30 years) compared to cheaper 3-tab shingles, which may only last 10–15 years.
  • Climate: Shingles in areas with extreme weather conditions, such as frequent storms or intense UV exposure, tend to degrade faster.
  • Maintenance: Regular maintenance is essential to prevent issues like leaks or premature wear.

Maintenance Requirements for Both Roofing Options

One major difference between metal roofs and asphalt shingles is the level of maintenance required.

Metal Roofs

Metal roofing requires minimal upkeep. Routine inspections are typically enough to ensure the roof remains in excellent condition. Tasks may include:

  • Removing leaves or debris that could trap moisture.
  • Verifying flashings and seals around vents and chimneys are intact.
  • Touching up paint on coated metal roofs if there’s any chipping.

Because metal roofs are highly durable, they rarely need repairs unless damaged by severe weather or improper installation.

Asphalt Shingles

Compared to metal roofs, asphalt shingles demand more regular attention:

  • Inspecting for and replacing damaged or missing shingles after storms.
  • Cleaning moss, mold, or algae growth to maintain aesthetic appeal.
  • Fixing leaks or cracks promptly to avoid costly repairs.

While asphalt shingles are less durable than metal roofs, proper maintenance can prevent significant damage and extend their lifespan.

Cost and Value Considerations

Deciding between a metal roof and asphalt shingles also boils down to cost. Below is a breakdown of initial installation costs, repair expenses, and long-term value.

Initial Costs

  • Metal Roofs tend to have higher upfront costs, ranging from $8 to $16 per square foot. Premium materials like copper will cost even more.
  • Asphalt Shingles, however, are much more affordable to install, costing between $3 and $8 per square foot.

Although the initial price tag for a metal roof is steeper, many homeowners view it as an investment due to its long lifespan and minimal maintenance needs.

Long-Term Cost-Effectiveness

Over the long haul, metal roofs offer better value:

  • They require fewer repairs and replacements compared to asphalt shingles.
  • Their durability means once you install a metal roof, you may not need another roof replacement in your lifetime.

On the other hand, asphalt shingles will typically require replacement every 15 to 30 years, increasing your costs significantly over time.

Environmental Impact

Both options have different environmental footprints you may want to consider.

Metal Roofs

Metal roofs are highly sustainable:

  • Many are made from recyclable materials, and they can also be fully recycled at the end of their lifespan.
  • Their reflective nature enhances energy efficiency by reducing cooling costs in hot climates.

Asphalt Shingles

Unfortunately, asphalt shingles are less environmentally friendly:

  • They are typically made from petroleum-based materials, which are not renewable.
  • Most asphalt shingles end up in landfills after being replaced, contributing to waste.

For eco-conscious homeowners, metal roofs are the clear winner.

Aesthetic Appeal and Design Options

Both metal roofs and asphalt shingles come in various styles, but they cater to different design preferences:

  • Metal Roofs can provide a modern, sleek appearance and come in various colors, finishes, and profiles.
  • Asphalt Shingles are more traditional and often feature a textured look to resemble wood or slate.

Your choice will depend on your home’s architectural style and personal taste.

Final Thoughts — The Clear Winner Depends on Your Needs

When comparing metal roofs vs. asphalt shingles, the right choice ultimately depends on your priorities. If you’re looking for:

  • Longevity with minimal maintenance, go for a metal roof.
  • Affordability upfront, asphalt shingles are a better fit.

Regardless of which one you choose, proper installation and maintenance play a critical role in extending your roof’s lifespan and ensuring your investment pays off.

Why Gutter Guards Are a Smart Investment for Long-Term Roof Health

August 5, 2025
Douglas County Roofing – Douglasville When you think about protecting your home from water damage, mold, and premature roof wear, your gutters play a more critical role than you might realize. At Douglas County Roofing in Douglasville, we know that maintaining a strong and healthy roofing system starts with clean, functional gutters—and that’s where gutter guards make all the difference. Here’s why gutter guards are a smart investment for long-term roof health, and how they can save Douglasville homeowners time, money, and headaches down the line. 1. Prevent Water Damage and Roof Rot Your gutters are designed to direct rainwater safely away from your roof and home. But when they become clogged with leaves, twigs, and pine needles, water can back up onto the roof and seep beneath the shingles. This leads to: Roof rot Mold growth Damaged fascia and soffits Interior ceiling leaks Gutter guards keep debris out, ensuring consistent water flow through your downspouts and away from vulnerable roofing components. 2. Reduce the Risk of Ice Dams in Winter Here in Douglas County, winter storms can bring freezing temperatures that lead to ice dams. When gutters are clogged, melting snow refreezes at the roof edge, causing water to back up and damage shingles, insulation, and ceilings. Installing gutter guards reduces clogs, helping water drain properly—even in colder months—so your roof stays safer year-round. 3. Extend the Life of Your Roof Every roof has a lifespan, but clogs and water damage can accelerate wear and tear. With the protection of gutter guards, you: Reduce moisture buildup Minimize algae and mildew growth Prevent heavy debris from stressing your gutter system Protect your shingles from premature deterioration That means fewer repairs and a longer-lasting roof, which protects your home’s overall value. 4. Lower Long-Term Maintenance Costs Cleaning gutters is messy, time-consuming, and potentially dangerous. Most Douglasville homeowners need to clean their gutters at least twice a year—or more if they have overhanging trees. With gutter guards from Douglas County Roofing, you’ll: Cut back on the frequency of gutter cleanings Avoid costly water damage repairs Save money on long-term roofing maintenance A one-time installation leads to years of reduced upkeep and improved peace of mind. 5. Protect Your Foundation and Landscaping Overflowing gutters don’t just harm your roof—they also wreak havoc on your foundation and yard. When water spills over the sides, it can: Erode soil and flowerbeds Crack your home’s foundation Lead to basement leaks and structural damage Gutter guards ensure that water is channeled safely away from your home, preventing thousands of dollars in potential repair costs. 6. Keep Pests Out of Your Gutters Clogged gutters are a breeding ground for unwanted pests like mosquitoes, birds, squirrels, and rodents. Stagnant water is also a perfect place for insects and mold to thrive. Gutter guards create a physical barrier, deterring nesting and infestations—keeping your home and roofline safer and cleaner. 7. Boost Your Home’s Resale Value A home that’s well-maintained is more attractive to potential buyers. Gutter guards show that you’ve invested in your property’s protection. They signal less maintenance and better roof condition—making your home more appealing when it’s time to sell.

How to Maintain Your EPDM Roof for Long-Term Durability

July 22, 2025
When it comes to roofing materials, EPDM (Ethylene Propylene Diene Monomer) stands out for its affordability, flexibility, and resistance to weathering. But like any roofing system, it requires proper care to maximize its lifespan. Whether your EPDM roof protects a residential home or a commercial property, following a regular maintenance plan can help you get the most out of your investment. At Douglas County Roofing in Douglasville , we’ve seen firsthand how a little upkeep goes a long way. Here’s your go-to guide for maintaining your EPDM roof for long-term durability. 1. Schedule Routine Inspections Why it matters: Catching minor issues early can prevent expensive repairs or even premature roof replacement. What to do: Schedule a professional inspection at least twice a year , ideally in the spring and fall . After severe weather events, have your roof checked for damage from hail, debris, or standing water. Tip: Our roofing experts in Douglasville offer detailed roof inspections tailored to EPDM systems. 2. Keep the Roof Clean and Clear Why it matters: Leaves, dirt, and branches can trap moisture or puncture the membrane. What to do: Gently sweep off debris using a soft broom. Avoid pressure washers, which can damage the membrane. Clear nearby tree limbs to prevent overhanging branches from causing damage. Pro Tip: Always use non-abrasive cleaners designed for rubber roofs. 3. Check for Ponding Water Why it matters: EPDM is water-resistant but not designed to hold standing water for long periods. What to do: After rain, inspect for areas where water lingers more than 48 hours. Ensure drains and gutters are clear and functioning properly. Consult a roofing contractor if ponding persists—it may indicate drainage or structural issues. 4. Inspect Seams and Flashings Why it matters: Seams and flashings are common weak points where water can seep in. What to do: Look for lifting edges, bubbling, or cracks . Sealants may deteriorate over time and need reapplication. Pay special attention to penetrations like vents, pipes, and skylights. Need Help? Our Douglasville team can quickly repair worn or damaged flashing before it causes interior leaks. 5. Use the Right Materials for Repairs Why it matters: Using incompatible products can break down the membrane or void your warranty. What to do: Only use EPDM-compatible patches, adhesives, and sealants . For long-term reliability, professional repairs are strongly recommended. 6. Avoid Unnecessary Foot Traffic Why it matters: EPDM membranes are tough, but repeated or careless walking can cause punctures or scuffs. What to do: Limit access to maintenance crews or HVAC workers. Use protective mats or walkways if foot traffic is unavoidable. 7. Address Damage Immediately Why it matters: Small cracks or punctures can quickly escalate into major leaks and structural issues. What to do: Don’t wait— even a small tear needs immediate attention . Document any damage and call a trusted EPDM roofing specialist right away.
