If you’re considering a metal roof for your home or commercial building, you may be wondering, how long do metal roofs last? Metal roofing is known for its durability, energy efficiency, and low maintenance, making it a popular choice for Brockton property owners. Unlike traditional asphalt shingles, which may need replacing every 20 years, metal roofs offer exceptional longevity, often lasting 40 to 70 years or more with proper care.
In this guide, we’ll explore the factors that influence metal roof longevity, compare different types of metal roofing materials, and provide maintenance tips to ensure your metal roof stands the test of time.
Understanding Metal Roof Longevity: What to Expect
How Long Do Metal Roofs Last on Average?
Metal roofing is one of the most durable roofing materials available. Depending on the type of metal and installation quality, you can expect the following lifespans:
- Steel Roofing: 40–70 years
- Aluminum Roofing: 50+ years
- Copper Roofing: 70–100+ years
- Zinc Roofing: 80+ years
- Tin Roofing: 50+ years
Compared to asphalt shingles, which typically last 15–25 years, metal roofs offer superior longevity and long-term cost savings.
Why Metal Roofs Last Longer Than Other Roofing Materials
Metal roofs outlast asphalt and wood shingles because they are resistant to common roofing problems such as:
- Weather Damage: Unlike asphalt, metal roofs withstand harsh weather conditions, including heavy snow, strong winds, and hail.
- Fire Resistance: Most metal roofs have a Class A fire rating, making them highly resistant to fire damage.
- Mold and Mildew Resistance: Metal doesn’t absorb moisture, preventing mold, rot, and algae growth.
- Pest Resistance: Unlike wood shingles, metal roofs are not susceptible to termites or rodents.
With proper maintenance, metal roofs in Brockton can exceed their expected lifespan, providing long-term protection for homes and commercial buildings.
Factors That Affect Metal Roof Longevity
1. Type of Metal Used
Not all metal roofs are created equal. Different metals offer varying levels of durability:
- Steel: The most common choice, steel roofing is coated with zinc or aluminum to prevent rust and corrosion.
- Aluminum: Naturally resistant to corrosion, aluminum is ideal for coastal areas but slightly softer than steel.
- Copper & Zinc: Premium roofing materials that develop a protective patina over time, extending their lifespan beyond 80 years.
2. Coatings and Finishes
Protective coatings significantly impact metal roof longevity by preventing rust and UV damage. Look for:
- Galvanized Steel (Zinc Coating): Prevents rust and corrosion.
- Galvalume Steel (Aluminum-Zinc Coating): Offers superior corrosion resistance.
- Paint Finishes (Kynar 500 or SMP): Helps reflect sunlight and prevents fading.
3. Climate and Weather Conditions
Brockton experiences a range of weather conditions that can affect metal roof longevity:
- Heavy Snow & Ice: Metal roofs shed snow easily, reducing weight strain.
- High Winds: Properly installed metal roofs can withstand winds up to 140 mph.
- Salt Exposure: Coastal areas may require aluminum or treated steel to prevent corrosion.
4. Installation Quality
A professionally installed metal roof lasts significantly longer than a poorly installed one. Proper installation ensures:
- Secure fasteners and seams to prevent leaks
- Adequate ventilation to prevent moisture buildup
- Proper flashing to protect against water infiltration
Always choose an experienced roofing contractor to install your metal roof to avoid premature wear and tear.
5. Roof Maintenance and Care
While metal roofs require less maintenance than other materials, regular care extends their lifespan. Essential maintenance tasks include:
- Cleaning debris and leaves from the roof surface
- Inspecting and tightening fasteners and seams
- Checking for scratches or dents that may lead to rust
- Cleaning gutters to prevent water buildup
Comparing Metal Roof Longevity to Other Roofing Materials
If you’re deciding between a metal roof and other roofing options, here’s how they compare in terms of lifespan:
| Roofing Material | Lifespan |
| Asphalt Shingles | 15-25 years |
| Wood Shingles | 20-30 years |
| Clay Tiles | 50-100 years |
| Slate Roofing | 75-100 years |
| Metal Roofing | 40-70+ years |
While some materials like slate and clay tiles also offer long lifespans, they are significantly heavier and require more structural support than metal roofing.
Is a Metal Roof a Good Investment for Brockton Homes and Businesses?
1. Energy Efficiency and Cost Savings
Metal roofs reflect solar heat, keeping buildings cooler in the summer. According to the U.S. Department of Energy (energy.gov) (energy.gov), metal roofs can reduce cooling costs by up to 25%.
2. Environmental Benefits
Metal roofing is one of the most eco-friendly options available. Benefits include:
- Recyclability: Most metal roofing materials are 100% recyclable at the end of their lifespan.
- Energy Efficiency: Reflective coatings reduce heat absorption, lowering energy bills.
3. Insurance Savings
Many insurance companies offer discounts for metal roofs due to their fire resistance, durability, and impact resistance. This can help lower long-term costs for Brockton property owners.
4. Resale Value
Homes with metal roofs often have higher resale values because buyers recognize their long lifespan and low maintenance needs.
Maximizing the Lifespan of Your Metal Roof
To ensure your metal roof lasts as long as possible, follow these best practices:
- Schedule Annual Inspections – A professional roofer can identify minor issues before they become major problems.
- Clean Your Roof Regularly – Remove debris, leaves, and dirt buildup.
- Check Fasteners and Seams – Tighten any loose screws and replace worn-out sealants.
