Metal Vs Asphalt Roof Installation Which one is Best for you

Choosing the right roof for your home is important. You might be thinking about metal vs asphalt roof installation for your home. Each has its own good and bad points.

Metal roofs last a long time but can cost more to put up. In hot places, metal roofs are good because they keep houses cooler. Asphalt roofs don’t last as long as metal roof shingles. They look traditional and are simple to fix if needed. 

Installing a metal roof over an existing asphalt roof can be feasible, but it’s important to consider potential drawbacks. Issues like additional weight and proper insulation must be addressed to ensure structural integrity and energy efficiency.

Here’s an in-depth guide on Why New Metal Roof Installation is Better Than Roofing Over an Asphalt Roof.

What Is Metal Roofing?


Metal roofing is a roofing system made from metal pieces or tiles. It’s known for its durability, longevity, and ability to withstand extreme weather conditions. Metal roofs can be made from a variety of materials, including steel, aluminum, copper, or zinc alloys, and they often come in different styles, like panels and metal roofing shingles.

Pros And Cons Of Metal Roofing

Below are some pros and cons of metal roofing, which you should consider while installing. 


  • Durability: Metal roofs are extremely durable and can withstand harsh weather conditions like heavy rain, snow, and high winds.
  • Longevity: A significant advantage of metal roofing is its long lifespan, often lasting 40-70 years.
  • Energy Efficiency: Metal roofs reflect solar radiant heat, reducing cooling costs by 10-25%.
  • Low Maintenance: Unlike other roofing materials, metal roofs require minimal maintenance, saving time and money in the long run.
  • Eco-Friendly: Metal roofs are often made from recycled materials and are 100% recyclable at the end of their life.


  • Cost: The initial metal roof cost can be higher than that of other roofing materials, making it a significant investment.
  • Noise: During rain or hail, a metal roof can be noisier than other types, though proper metal roof insulation can mitigate this issue.
  • Expansion and Contraction: Metal roofing materials can expand and contract with temperature changes, which requires additional considerations during metal roof installation.
  • Inconsistency in Color Match: Over time, finding an exact match for metal roof colors can be challenging, especially for repairs.
  • Denting: Some types of metal roofing can dent from hail damage or heavy falling objects. 

What Is Asphalt Roofing?

What Is Asphalt Roofing

Asphalt roofing is a popular type of roofing material, particularly in residential buildings. It’s primarily made from asphalt shingles, which are composed of a fiberglass or organic base, coated with asphalt, and then with granules to add color and texture.

Pros And Cons Of Asphalt Roofing

Here are some pros and cons of asphalt shingles for homeowners when installing a roofing system. 


  • Affordability: One of the biggest advantages of asphalt roofing is its cost-effectiveness. It’s usually much cheaper than other roofing materials.
  • Ease of Installation: Asphalt shingles are relatively easy and quick to install, which can reduce labor costs.
  • Versatility: Asphalt shingles come in a variety of colors and styles, making them suitable for a wide range of architectural designs.
  • Accessibility: Asphalt shingles are widely available and can be easily sourced from most home improvement stores or roofing suppliers.
  • Repairability: Repairing an asphalt roof is generally straightforward. Damaged shingles can be replaced individually without the need to address the entire roof.


  • Shorter Lifespan: Asphalt roofs typically have a shorter lifespan than other roofing materials, often lasting between 15 to 30 years.
  • Vulnerability to Weather: Asphalt shingles can be prone to damage from extreme weather conditions, like high winds, heavy rain, or hail.
  • Environmental Concerns: Asphalt shingles are not the most environmentally friendly option as they are petroleum-based and not easily recyclable.
  • Temperature Sensitivity: In high temperatures, asphalt shingles can become soft and more susceptible to damage. In cold climates, they can crack and lose their flexibility.
  • Algae and Moss Growth: Asphalt roofs may become saturated with algae and moss, affecting their appearance and possibly their longevity.
