From steel to wood to clay, there are many roofing materials to choose from and it can be overwhelming to narrow down your search. Even with a variety of options available, two materials remain the most popular: metal and asphalt. Despite sharing some similarities, the two are quite difficult, so how do you decide which is better between metal and asphalt?
The expert roofers at Top Home Roofers have created this comprehensive guide to compare and contrast a metal roof vs asphalt through the lens of longevity, costs, pros and cons, maintenance, sustainability, installation, and more.
Difference in Materials
The main differences between these two roofing materials are metal roofs are easier to maintain, longer lasting, and more eco-friendly, whereas asphalt roofs are cheaper, quieter, and easier to install.
Continue reading to find out some more key differences between a metal vs asphalt roof.
How Long Do Metal Vs Asphalt Roofing Lasts
Metal roofs are extremely durable and can withstand severe weather conditions such as heavy snow, torrential rain, intense heat, freezing cold, and stormy winds. The average lifespan of a metal roof is 40 to 70 years and most come with 30 to 50-year warranties. As long as they are properly installed and maintained regularly, it’s likely a metal roof is the only roof you’ll ever need in your lifetime!
Asphalt shingles on the other hand have an expected lifespan of 15 to 30 years. They are most vulnerable to humidity and moisture and pooling water from heavy rain or long-lasting ice can lead to cracks and mold growth. Since asphalt roofing is more fragile, it’s important to observe the existence of deterioration, storm damage, roof leaks, missing shingles, or other issues taking place on your roof so you know when it’s time to replace it.
Cost of Metal Roof Vs Asphalt
When comparing metal vs asphalt roof costs, asphalt is the more affordable option. Asphalt shingles cost anywhere between $4 to $8 per square foot, which means the average price to replace a 1,000 square foot roof with asphalt materials is $6,000.
Conversely, metal roofing costs between $4.50 and $16 per square foot. Though metal roofing costs more upfront, you will save in the long run because of its longevity and the little maintenance required for upkeeping. You can also save up to 25% in energy costs if solar reflective coating is used when installing, optimizing ventilation.
Maintenance Difference
The two main factors that impact the frequency and expense of roof maintenance for both materials is climate and how well the roof was installed. In general, metal roofs require less maintenance than asphalt shingles since they’re less vulnerable to moisture. Asphalt shingles are more commonly the cause of problems because of how light they are and vulnerable to cracking when exposed to extreme temperature fluctuations.
Regardless of metal or shingle roofing material, our roofing experts recommend inspecting your roof at least once per year to check for any debris or damage that could cause a leak. Regular maintenance includes inspecting for damage, cleaning off the metal panels, keeping snow and ice off the roof, removing debris from valleys and gutters, trimming branches near your home, repairing scratches and rust spots, and checking for corrosion.
Sustainability
Asphalt is far less eco-friendly than metal. Millions of asphalt materials get sent to landfills every year since they cannot be recycled. Asphalt is a petroleum-based product, which means they increase fossil fuel dependency.
Fortunately, metal roofing materials are 100% recyclable, as they can be repurposed into new materials after being removed from your roof. They are a much better choice for the environment and a sustainable roofing option. Plus, their reflective nature helps prevent heat transmission, adding to their energy efficiency.
Installation Between Metal Roofing Vs Asphalt
Asphalt shingles are easier and quicker to install over metal materials. Asphalt roofing installation takes about one to two days whereas metal roofing materials can take a few days to a couple of weeks to complete.
With regards to both materials, adverse weather conditions, complex roof designs, steep slopes, and the size of your roof may extend the installation timeline.
Pros and Cons of Metal Roofing
Metal roofing is available in many different styles, the three most common being: standing seam panels, metal shingles, and exposed fastener panels. A standing seam metal roof features panels at the seam that are locked together, allowing them to easily expand and contract as the temperature changes. Metal shingles mimic the look of traditional roofing materials while exposed fastener panels are attached to the roof with nails or screws or nails.
You can select from several types of metal, including steel, aluminum, zinc, and copper. Costs will increase based on the weight and durability of the metal you choose; however higher quality metal typically leads to a better return on investment.

Pros and Cons of Asphalt Roofing
Similarly to the variety in metal, there are three different types of asphalt shingle roofing options. Basic three-tab asphalt shingles are designed thin, flat, and with a brick-like pattern. Dimensional or architectural asphalt shingles have a thicker and more textured appearance. Designer or luxury asphalt shingles are also thicker, but with a texture that mimics premium roofing materials like wood shakes or slate tiles.
Dimensional asphalt shingles are the most popular of the three options, as homeowners are drawn to its curb appeal and midrange cost.

To Conclude
The choice between metal vs. asphalt roofing comes down to cost, durability, maintenance, installation, and sustainability. Metal roofs offer impressive longevity and durability but come with a higher initial cost.
Asphalt shingles are more budget-friendly yet offer less weather resistance and require more frequent repairs. Roof replacement is a major investment, so we advise you to take time to explore all your options.
FAQs
What is better: a metal or shingle roof?
If you want a more durable, energy-efficient roofing material, then metal is better for you. However, if you’re on a tighter budget, then a roof made of asphalt shingles might suit you greater financially.
Are metal roofs louder than asphalt roofs?
Though metal roofs are louder than asphalt roofs, the difference is insignificant. Metal roofs subdued noise is helped by being installed over a layer of insulation and plywood sheathing. They are only around eight decibels louder than an asphalt roof and the attic space also assists with supressing sound.
