Asphalt shingles are primarily made from a fiberglass mat saturated with asphalt, making them less durable against extreme temperatures compared to metal roofs, which are often made from steel or aluminum and can withstand harsher conditions.
Metal roofs can last between 40 to 70 years, while asphalt shingle roofs typically last about 20 to 30 years, making metal roofs a potentially more cost-effective option over time despite their higher initial price.
The reflective properties of metal roofs can significantly reduce heat absorption, which can lower cooling costs in warmer climates by minimizing the heat retained in a home.
In terms of weight, asphalt shingles weigh about 2 to 4 pounds per square foot, while metal roofs weigh only 1.5 to 3 pounds per square foot, which can be beneficial for homes that cannot support heavy roofing materials.
Noise is an important consideration; while metal roofs can be noisier during heavy rain or hail, additional insulation or underlayment can mitigate this effect, whereas asphalt shingles tend to absorb sound better.
Metal roofing can be recycled at the end of its life, making it a more environmentally friendly option compared to asphalt shingles, which are typically sent to landfills.
Installation of asphalt shingles is generally easier and can often be done by knowledgeable DIY homeowners, whereas metal roofing often requires professional installation due to its complexity.
In terms of fire resistance, metal roofs are non-combustible and often rated Class A for fire resistance, while asphalt shingles can be more susceptible to fire, especially in areas prone to wildfires.
Asphalt shingle roofs are more prone to damage from high winds, especially if they are older or have not been properly maintained, whereas metal roofs can withstand winds of up to 140 miles per hour.
Color options for metal roofs are extensive and can often be customized, while asphalt shingles typically come in a limited range of colors and styles but may also simulate the appearance of more expensive materials.
Thermal cycling, which refers to the expansion and contraction of materials with temperature changes, can degrade asphalt shingles over time, leading to cracking, while metal roofs are less affected by this phenomenon.
Metal roofs can be installed over existing shingles, which can save on removal costs and labor, while asphalt shingles typically need a solid deck for installation, which can add to the overall cost if repairs are needed.
The higher upfront cost of metal roofing can result in a lower overall cost of ownership due to reduced maintenance and replacement needs, making them potentially more economical in the long run.
In some regions, homeowners insurance premiums may be lower for homes with metal roofs due to their durability and fire resistance, whereas asphalt shingles may not offer the same benefit.
While asphalt shingles can fade and lose granules over time due to UV exposure, metal roofs often come with coatings that help prevent fading, maintaining their appearance longer.
Metal roofs can help with snow and ice management, as their smooth surface allows snow to slide off easily, reducing the risk of ice dams, which commonly occur with asphalt shingle roofs.
The installation time for a metal roof can be shorter than that of asphalt shingles because fewer materials are needed and they can often be installed in larger panels.
The color and finish of metal roofs can influence energy efficiency; lighter colors reflect sunlight and can reduce cooling costs, whereas darker colors may absorb heat.
Some metal roofs come with a warranty of up to 50 years or more, while traditional asphalt shingles typically come with a warranty of about 20 to 30 years, reflecting their differing life spans.
In terms of aesthetics, metal roofs can fit a modern or contemporary design while asphalt shingles are often associated with traditional architectural styles, providing distinct visual choices for homeowners.
