Asphalt Roof vs. Metal Roof: Which One Lasts Longer?

When choosing between asphalt roofing and metal roofing, one of the primary considerations is longevity. Both materials offer unique benefits and drawbacks, which can significantly influence your decision. In this article, we will explore the key factors in the debate of asphalt roof vs. metal roof and determine which one lasts longer.

Longevity of Asphalt Roofs

Asphalt roofs, particularly those made from asphalt shingles, typically last between 15 to 30 years. The lifespan depends on several factors, including:

  • Quality of Materials: Higher-quality asphalt shingles tend to have longer lifespans. Architectural shingles often last longer than three-tab shingles.
  • Climate: Regions with extreme weather conditions can shorten the lifespan of asphalt roofs.
  • Installation: Proper installation is crucial for maximizing longevity. Poorly installed roofs may fail prematurely.

Type of Asphalt ShingleAverage Lifespan
Three-Tab Shingles15-20 years
Architectural Shingles25-30 years
Premium Shingles30+ years

Longevity of Metal Roofs

In contrast, metal roofs can last anywhere from 40 to 70 years, with some premium metal roofing systems exceeding this range. Factors influencing the lifespan of metal roofs include:

  • Material Type: Aluminum, steel, and copper all have different longevity profiles. For example, copper can last over 70 years, while galvanized steel typically lasts around 40 years.
  • Maintenance: Regular maintenance, such as cleaning and repainting, can enhance the lifespan of metal roofs.
  • Installation Quality: Like asphalt roofs, the quality of installation plays a vital role in longevity.

Aluminum50 years
Copper70+ years

Cost Comparison: Asphalt vs. Metal Roofing

When evaluating asphalt roof vs. metal roof, cost is a significant factor. Here’s a breakdown of the typical costs associated with each roofing type:

Installation Costs

The installation costs can vary widely depending on local labor rates and specific materials used. Here’s a general overview:

Roofing MaterialAverage Installation Cost per Square (100 sq ft)
Asphalt Shingles$90 – $100
Metal Roofing$120 – $900

Long-Term Cost Considerations

While the upfront costs for metal roofing are generally higher than asphalt, their longevity and durability may offset these initial expenses over time. Here’s a summary of long-term costs:

Roofing MaterialAverage LifespanReplacement Cost (every 30 years)Total Cost Over 60 Years
Asphalt Shingles20 years$8,000 – $12,000$16,000 – $24,000
Metal Roofing50 years$12,000 – $20,000$12,000 – $20,000

Durability Factors: Asphalt vs. Metal

Weather Resistance

Metal roofs generally offer superior resistance to severe weather conditions, such as high winds, hail, and snow. Here’s how they compare:

  • Wind: Metal roofs can withstand winds of up to 140 mph, while asphalt shingles are rated for winds up to 60-80 mph.
  • Hail: Metal roofs are less likely to be dented or damaged by hail, while asphalt shingles can crack or become dislodged.

Fire Resistance

In terms of fire resistance, metal roofs are considered non-combustible and are typically rated Class A, while asphalt shingles can vary in their fire ratings. This makes metal roofs a safer option in fire-prone areas.

Maintenance Requirements

Asphalt roofs require more maintenance than metal roofs. Homeowners must regularly inspect and replace damaged shingles, which can be time-consuming and costly. Metal roofs, on the other hand, often require less frequent maintenance, primarily focused on checking for rust or loose fasteners.

Aesthetic Considerations: Asphalt vs. Metal

Design Versatility

Asphalt roofing offers a wide range of styles, colors, and textures, making it a popular choice for residential properties. Homeowners can easily match asphalt shingles to the style of their home.

Metal roofing has also evolved significantly, with many options that mimic traditional materials like slate or shingles. However, some homeowners may still perceive metal roofing as industrial or less aesthetically pleasing.

Resale Value

While both roofing types can enhance a home’s value, metal roofs may offer a better return on investment due to their longevity and energy efficiency. Prospective buyers often see metal roofs as a more reliable investment, particularly in regions prone to severe weather.

Environmental Impact: Asphalt vs. Metal

Sustainability

When considering the asphalt roof vs. metal roof debate, sustainability is an important factor. Asphalt shingles are petroleum-based products and can contribute to environmental concerns regarding oil extraction and carbon emissions. In contrast, many metal roofing options are made from recycled materials, making them a more eco-friendly choice.

Energy Efficiency

Metal roofs are also known for their energy efficiency. They reflect solar heat, which can help reduce cooling costs in warmer climates. While asphalt roofs can be treated to improve their energy efficiency, they generally absorb heat, leading to higher energy consumption.

Conclusion on Longevity and Other Factors

In the battle of asphalt roof vs. metal roof, it’s clear that metal roofs generally outlast asphalt roofs, with an average lifespan of 40 to 70 years compared to 15 to 30 years for asphalt. Additionally, metal roofs offer superior durability, weather resistance, and lower long-term maintenance costs.

The choice ultimately depends on your specific needs, budget, and aesthetic preferences. Understanding the differences in lifespan, cost, and overall benefits of asphalt roofing vs. metal roofing can help you make an informed decision that best suits your home and lifestyle.
