Pros and Cons of a Metal Roof Vs. Asphalt Shingles

Choosing the material for your new roof can be a daunting task. Should you choose a metal roof? Asphalt shingles? Slate? Clay? The options seem endless. We’re here to give you the pros and cons of the two most common types: a metal roof and asphalt shingles. 

Pros and Cons of a Metal Roof

Before committing to a metal roof, there are a few things to keep in mind. While a metal roof may look like the superior option, there are some drawbacks as well. But let’s start with the pros.

Pros of a Metal Roof

1. Long lifespan - One of the biggest pros to choosing a metal roof is the longevity of the product. A metal roof will last 40-70 years, while an asphalt roof will only last around 15-25 years. The life expectancy difference between these two products is huge, with the metal roof being the clear winner.
2. Extremely durable - A metal roof is able to withstand most weather conditions. Metal roofs have proved to be durable with winds up to 140 mph. That’s the equivalent of an F2 tornado or category 4 hurricane! Metal roofs can also withstand large hail, although it may affect the roof cosmetically. And with the right components and installation, a metal roof can even meet the Class A fire rating. In general, metal roofs are able to withstand weather conditions that would destroy asphalt shingles.
3. Environmentally friendly - Since a metal roof is only replaced every 40-70 years, the amount of waste is minimal. And since a metal roof is 100% recyclable, there’s essentially no part of the roof that ends up in the landfill. This makes a metal roof an extremely environmentally friendly option for homeowners.
4. Energy efficient - Metal roofs are reflective, which helps tremendously with the energy efficiency of your home. A metal roof reflects heat away from your home, keeping the inside cooler and energy costs lower.
5. Style flexibility - Metal roofs provide plenty of style and color options to choose from. Some metal roofs are able to incorporate traditional styles (shake or slate) into a metal roof, giving you the style you want with the durability you need.

Cons of a Metal Roof

1. High upfront cost - A metal roof will certainly pay for itself over time, but there’s no way to avoid the high upfront cost. High end metal roofs can be more expensive than asphalt shingles, but it typically ends up being only a couple thousand dollars more. Establishing a budget will be incredibly important before committing to a metal roof.
2. Noisy - A metal roof will make noise when anything hits it, especially when it rains. You can counter this problem by adding insulation, but that will be an added expense in your project.
3. Prone to dents - Anything falling on your metal roof can potentially cause dents. This could include large tree branches, hail, debri during storms, etc. Choosing a higher grade metal will help combat this problem, although dents are still possible.
4. Rust - If any amount of water sits on your roof, rust can occur. You’ll want to regularly check your roof after storms to make sure the water is properly flowing off of it.
5. Difficult to repair - Metal roofs are installed in giant panels. If one part becomes damaged, the entire panel will likely need to be replaced. This could make repair more difficult or costly.

Pros and Cons of Asphalt Shingles

Asphalt shingles can be a great choice for your home. They may not have the longevity of a metal roof, but the upfront savings they offer is unbeatable. Here are the pros to choosing asphalt shingles.

Pros of an Asphalt Roof

1. Affordable - There’s no denying that asphalt shingles are considerably cheaper than other roofing options. For homeowners on a tight budget, this could be a giant benefit.
2. Style flexibility - Asphalt shingles are available in a variety of colors and styles. Certainteed offers an abundance of styles to match every type of home.
3. Easy installation & replacement - Asphalt shingles are lightweight and easy to cut. This makes them easier to transport and install on a roof. Since shingles are applied in smaller pieces, it’s much easier to replace a single damaged shingle.
4. Effective - An asphalt shingle does its job- keeps the elements out of your home.

Cons of an Asphalt Roof

1. Small life span - Asphalt shingles are known for needing to be replaced more often. The average lifespan of an asphalt roof is 12-20 years, with metal roofs lasting 40-70 years.
2. Wind damage and cracking - Wind uplift is a big problem with asphalt shingles. They are also prone to cracking, especially in extreme weather fluctuations. You may find yourself replacing shingles more often because of this.
3. Mildew - Your roof is susceptible to mold and mildew, especially if any part of your house is shaded. Rainy, humid conditions promote algae growth, causing moss to form on the roof. Moss keeps your roof damp, which then causes the mold and mildew to grow and spread. Removing any growth that forms on your roof is critical when choosing asphalt shingles.
4. Not environmentally friendly - While a metal roof is completely recyclable, an asphalt roof is not. Once the old asphalt shingles are removed, they are useless and will end up in a landfill. Plus, because of their small lifespan, this will happen more frequently.

The Consensus is…

Both types of roofs have plenty of pros and cons. In the end, it all depends on what your needs and budget allow. If you have the budget for a high-grade metal roof, the high upfront cost is sure to pay for itself over time. 

However, if you’re a homeowner on a smaller budget, you may consider asphalt shingles instead. Either way, both options require you to be proactive to extend the life of your roof. Whether you see moss growth on your asphalt shingles or sitting water on your metal roof, proper care is required to get the most out of your brand new investment.
