Asphalt Roof vs. Metal Roof: Which One Lasts Longer?
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.
Comparison Table: Lifespan of Asphalt Roofs
Type of Asphalt Shingle | Average Lifespan |
---|---|
Three-Tab Shingles | 15-20 years |
Architectural Shingles | 25-30 years |
Premium Shingles | 30+ 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.
Comparison Table: Lifespan of Metal Roofs
Type of Metal Roof | Average Lifespan |
---|---|
Steel | 40-60 years |
Aluminum | 50 years |
Copper | 70+ 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 Material | Average 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 Material | Average Lifespan | Replacement Cost (every 30 years) | Total Cost Over 60 Years |
---|---|---|---|
Asphalt Shingles | 20 years | $8,000 – $12,000 | $16,000 – $24,000 |
Metal Roofing | 50 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.
