Advantages and Disadvantages of Asphalt Shingles: A Comprehensive Analysis
Asphalt shingles are a popular choice for roofing due to their affordability and wide availability. However, like any other material, they come with their own set of advantages and disadvantages. In this article, we will explore the benefits and drawbacks of using asphalt shingles as a roofing material.
Advantages of Asphalt Shingles
Cost-Effectiveness: One of the main advantages of asphalt shingles is their cost-effectiveness. They are generally cheaper than other roofing materials such as metal or tile, making them a favorable choice for homeowners on a budget.
Wide Availability and Style: Asphalt shingles are easily obtained and come in a variety of colors and styles, making them a versatile option for enhancing the curb appeal of any home.
Durability and Weather Resistance: These shingles are designed to withstand various weather conditions, including heavy rain, snow, and hail. With proper maintenance, they can last anywhere from 20 to 30 years, providing long-term protection for your home.
Easy Installation and Repair: Asphalt shingles are straightforward to install and repair, which reduces labor costs. This simplicity makes them a popular choice for both new installations and roof repairs.
Fire Resistance and Sound Insulation: Asphalt shingles offer good fire resistance, which is crucial for safety. Additionally, they provide excellent sound insulation, contributing to a comfortable living environment.
Disadvantages of Asphalt Shingles
While asphalt shingles have their advantages, they also come with certain drawbacks:
Vulnerability to Weather Damage: Despite their weather resistance, asphalt shingles can become brittle and crack with prolonged exposure to the elements, especially in extreme climates or repeated weather events.
Shorter Life Expectancy: Recent findings indicate that even high-quality asphalt shingles are lasting significantly shorter than their expected lifespan. This is due to the use of less petroleum in the production process, leading to premature failure.
Lack of Energy Efficiency: Unlike more energy-efficient materials such as metal, asphalt shingles can increase the overall energy consumption of a home, especially in warmer climates.
Susceptibility to Moss and Mildew: The organic matter often found in the composition of asphalt shingles can make them vulnerable to moss and mildew growth, which can further damage the structure over time.
Current State of Asphalt Shingles
Based on our experience over the past 50 years, we have observed a significant decline in the quality of asphalt shingles. Even high-end products are now failing within 9 to 12 years, despite boasting 25 to 35-year warranties. These warranties are often prorated, meaning the longer you have the shingles, the less money you get for the warranty. Moreover, these warranties do not cover the labor costs associated with removing and replacing failed shingles.
Our belief is that these warranties are more of a sales tactic than a genuine promise of quality. Therefore, we no longer install asphalt shingles. Instead, we recommend metal roofs, which offer real, reliable warranties and can last much longer with minimal maintenance.
Comparison with Metal Roofs
Cost-Effectiveness: While asphalt shingles are initially cheaper, metal roofs can cost only 20% more and offer significantly longer durability.
Warranties: Metal roof warranties are genuine and often guaranteed for 40 to 50 years, providing long-term peace of mind.
Fire Safety: Metal roofs offer superior fire safety compared to asphalt shingles, with metal being non-combustible.
Wind, Hail, and Storm Damage: Metal roofs are less prone to wind, hail, and storm damage, providing better protection for your home.
Environmental Impact: Metal roofs cause significantly less environmental damage over their lifetime due to their long-lasting nature.
Conclusion
As we have witnessed, the advantages of asphalt shingles are mainly in their initial cost and ease of installation. However, the disadvantages, particularly in terms of durability and maintenance, outweigh these benefits. For homeowners seeking a reliable and long-lasting roof, metal roofs may be the better choice.
