Metal Roof vs. Asphalt Shingle Roof: The Complete Guide

What’s the Difference Between an Asphalt Shingle and Metal Roof?

Asphalt shingle roofing is a dominant material for residences. However, metal roofing is surging in popularity as more aesthetic options become available. Now, there are metal shingles and panels that imitate materials like slate, tile, wood shake and even asphalt.

It’s important to navigate the pros and cons of each material before you decide which to use because this is a significant and long-term investment. Below we compare the two side-by-side in categories such as cost, durability and return on investment.

Metal Roofing Types

Metal is light, energy efficient and durable. It comes in a variety of formats and designs, including shingles, standing seam, wooden shake and tile. This makes it a versatile and appealing product.

Asphalt Roofs

Asphalt shingles are the most popular roofing material. They are available in a variety of colors and textures, are low-cost and provide a traditional aesthetic.

Fiberglass core or matting, an asphalt coating and a ceramic or stone granule surface give this material its durability. The granules protect the shingles from climate conditions and UV rays.

Standard three-tab are the most common type of shingle, but laminated and architectural asphalt shingles are gaining popularity as they become more widely available.

Architectural Shingles

Architectural shingles, also known as “laminate” or “dimensional” shingles, are made up of the same elements as their traditional counterparts, but are heavier, thicker and more expensive.

They will last longer than three-tab products and have longer warranties. You’ll find them in a variety of colors and textures, some of which simulate wood and slate, and many homeowners are attracted to the “dimensional” effect of the mixed sizes of these shingles.

Pros & Cons of Metal vs Asphalt Shingle Roofs

When it comes to these two materials, there are categories in which one or the other is clearly the best choice. But, there are also categories in which the choice comes down to preference.

The following guide addresses the advantages and disadvantages of metal roofing in general (rather than particular sub-types) versus three-tab asphalt shingles. This chart outlines the best options for major considerations and uses.

DIY Installation

Regardless of material, installing a roof is dangerous work that requires specific skills, tools and safety equipment. We do not suggest that any homeowner pursue this project on their own.

Metal
Pros

  • Many are light and easy to work with
  • Can often install without removing the old roofing.

Cons

  • Often calls for underlayment and plywood framing, which requires specific skills.
  • Some types are much heavier to work with.
  • It can cut the skin if handled improperly or without gloves.

Asphalt
Pros

  • Relatively easy to work with and install.

Cons

  • Could void product warranties.
  • May need to remove the old roofing, which adds time.

Easiest to DIY: Asphalt

Length of Life

You can get the longest life out of your roofing materials if you have them installed professionally and properly, you adhere to best roofing maintenance practices and you use the best materials for your climate and environment.

  • Metal: about 40-70 years.
  • Asphalt: around 15 to 20 years. Heavier or laminated products can last 25 to 30 years.
Longest Life Expectancy: Metal

Energy Efficiency

Metal
Pros

  • Extremely energy efficient.
  • Especially effective in reducing energy consumption in summer.
  • Typically made from recycled materials.
  • Continuously recyclable.

Cons

  • If installed incorrectly, efficiency will not be as high.

Asphalt
Pros

  • Absorbs heat and warms the home in the winter.

Cons

  • Heat absorption is a disadvantage in the summer time.
  • Products typically end up in landfills, are not recyclable and contain chemicals that are toxic.

Greenest Material: Metal

Durability & Weight

Metal
Pros

  • Extremely durable, lightweight and water resistant – some of the greatest benefits of metal roofing.
  • It’s durability contributes to long life expectancy and resistance to the elements.

Cons

  • Susceptible to denting from hail or fallen branches.

Asphalt
Pros

  • Their heavy weight (compared to some metals like aluminum) makes them less prone to uplift.

Cons

  • Less durable than metal, and can be heavier.
  • 100 square feet could weigh 200 to 500 pounds

Most Durable: Metal

Fire, Water & Hail Resistance

Metal
Pros

  • Resistant to weather, fire and climate conditions.
  • Does not rot.
  • Can be fortified against rust with a coating.
  • Seals out water and prevents water damage.

Cons

  • Prone to dents in hail storms, especially thinner varieties.

Asphalt
Pros

  • Many have high ratings for fire safety.
  • There are impact-resistant product options at a higher rate.

Cons

  • Standard varieties are vulnerable to weather and climate.
  • Can grow moss and algae.
  • Could incur damage from hail and UV rays.

Greatest Resistance: Metal

Painting or Sealing

Metal
Pros

  • Painting and coating are simple processes that keep the roof in good condition and protect it from the elements.
  • When unpainted or uncoated, it is vulnerable to rust and corrosion.
  • Professionally coating a metal roof costs $1-$2 per square foot.

Cons

  • A full paint job or repainting is a significant endeavor, and painting a metal roof costs between $1,100 and $3,700.
  • You will need to make this investment every few years, which adds to the cost of your investment over time.

Asphalt
Pros

  • These products benefit from sealing because it protects them from weather, leaks and sun exposure.
  • Pros can apply a sealant upon installation and use it to fix leaks in the future.

Cons

  • If your shingles need resealing, it is safest and most efficient to hire a professional.
  • Also, using a sealant to repair a leak is not a long-term fix and it may be more efficient to replace individual shingles.

Ideal for Painting/Sealing: Metal

ROI & Resale Value

In general, installing a new roof can add resale value and has consistently high returns on investment. According to Remodeling magazine’s 2018 Cost vs. Value Report, a midrange roofing replacement has a 68.4 percent ROI.

Metal
Pros

  • This material is energy efficient, long-lasting and weather resistant, all of which are draws for buyers.
  • It can raise resale value and have a high return on investment.

Cons

  • Resale value and ROI may not be as high if the style and color do not fit buyers’ tastes or the aesthetic of the area.

Asphalt
Pros

  • Architectural shingles will have a greater return than traditional ones.

Cons

  • Because this style is standard, it doesn’t have a larger impact on resale value or ROI beyond the benefit of a new roof.

FAQs

Is Metal More Expensive Than Asphalt to Install on a Roof?

In most cases, metal roofing and installation is more expensive than asphalt. However, there are expensive architectural shingles that cost more than lower-cost metals like aluminum.

Can You Add Metal Roofing over Shingles?

You can usually install metal roofing over shingles because most types are lightweight, thin and pliable. However, it is best to consult with a professional as to your situation. You want to be sure that the roof and shingles are in suitable shape for the project.

Check with your local building department or county because they may require that you remove the shingles or have a thorough inspection before installing a new roof. For example, many building departments set a two-layer limit on residential roofing.

Is It Difficult to Replace Asphalt with Metal?

Replacing shingles with metal roofing is not necessarily difficult, but it will require labor and time. The removal itself could cost anywhere from $3 to $5 per square foot. However, you do have the option of leaving the shingles in place and installing the roofing over them if the roof is in good shape.
