Asphalt shingle and Metal roof

Asphalt shingles and metal roofing are common materials used for covering residential roofs.[1] The choice between them often depends on budget, climate, and long-term goals.[1] Asphalt shingles have a lower initial installation cost, while metal roofing generally has a higher upfront expense but a longer lifespan.[2][3]

Comparison Table

Category Asphalt shingle Metal roof
Lifespan 15 to 30 years, depending on the type and environmental factors.[4] 40 to 70 years or longer, depending on the metal.[5]
Initial Cost Lower upfront cost, averaging between $5,400 to $9,800 for a typical installation. Higher upfront cost, typically ranging from $6,700 to $24,500 or more.
Durability More vulnerable to damage from high winds, hail, and temperature fluctuations. Granule loss from UV exposure can occur over time.[4] Highly resistant to wind, fire, and insects. Can be susceptible to denting from hail, depending on the material.[3]
Maintenance May require more frequent repairs, typically every 5-10 years for minor issues like replacing damaged shingles. Requires minimal maintenance, with inspections needed for signs of rust or other damage. Can go 15-20 years without needing repairs.[5]
Energy Efficiency Less energy-efficient, as darker shingles absorb more solar heat, which can be transferred into the attic. More energy-efficient, reflecting solar heat away from the building, which can reduce cooling costs.
Installation Simpler and faster to install, which contributes to lower labor costs.[4] More complex installation that requires specialized contractors, increasing labor costs.
Environmental Impact Composed of petroleum-based asphalt and fiberglass. An estimated 11 million tons are sent to landfills annually in the U.S.[4] Often contains recycled material and is 100% recyclable at the end of its service life.

Durability and Weather Resistance

Metal roofs are generally more durable than asphalt shingles. They are highly resistant to fire, rot, and insects. While asphalt shingles can be prone to wind uplift and damage from hail, metal roofs can withstand stronger winds and are less likely to be punctured. However, some metal materials, like aluminum, can be dented by severe hail.[3] Modern architectural asphalt shingles have improved durability, with some carrying a Class 4 impact rating similar to metal roofing.

Cost Considerations

The primary advantage of asphalt shingles is their lower initial cost.[3] A shingle roof replacement costs significantly less upfront than a metal roof. Over the long term, a metal roof may be more cost-effective because it can last two to three times longer than an asphalt shingle roof, reducing the need for multiple replacements. Repair costs for asphalt shingles are also typically lower than for metal panels, which require specialized labor.

Environmental and Energy Factors

Metal roofing is considered a more environmentally friendly option. It is often made with recycled content and can be fully recycled at the end of its life. In contrast, most old asphalt shingles are sent to landfills.

Metal roofs also offer better energy efficiency. Their surface reflects solar radiant heat, which helps to keep attics cooler and can reduce home cooling costs by up to 25%. Standard asphalt shingles, particularly in dark colors, tend to absorb heat. While some "cool" asphalt shingles with reflective granules exist, they are generally less reflective than coated metal panels.
