Pros and Cons of a Metal Roof

Metal roofs are a common choice, both in new construction and when an aging roof needs to be replaced. Metal roofing products can be made from a variety of metals, including galvanized steel, copper, aluminum, or tin, and they can use several different installation systems. There are a great many advantages to a metal roof, but there are also a few disadvantages to consider. Learn about the pros and cons of metal roofs and if this type is right for your home.

What Are the Pros of Metal Roofs?

Metal roofs continue to grow in popularity, Here are the many advantages of a metal roof:

Longevity

The life expectancy is 50 to 75 years or even more, as opposed to the 15 to 25 years of life for an asphalt shingle roof.

Energy efficiency

The surface reflects heat, lowering cooling costs in hot climates. The material also decreases the need for running air conditioning and cooling systems. Metal roofs can save up to 40 percent on energy costs.

Durability

They are less susceptible to leaking than shingles when installed correctly. They resist wind damage better than other roofing choices. Metal roofs are fireproof, making them good choices in areas where wildfire is a risk.

Environmentally friendly

Metal roofs are recyclable when they reach the end of their useful life. There is about a minimum of 25 percent recycled content in metal roofs. With an asphalt roof, there is an increase in building-related waste due to shingle tear-off and damage.

Safety

The misconception that metal roofs attract lightning is probably because metal itself is known as a good conductor of electricity, and people, therefore, assume that a metal roof must attract lightning. In reality, when lightning strikes, it is seeking a path to the ground and almost always will strike whatever object is highest in the area that also has a direct path to the ground. Your metal roof is not grounded, and thus, lighting has no reason to strike it.

What Are the Disadvantages of Metal Roofs?

Fear of lightning strikes may be an imaginary problem, but there are a few genuine disadvantages to metal roofs.

Cost

Metal roofs are considerably more expensive than most other options. When compared to an asphalt shingle roof, for example, a metal roof is at least twice as expensive. Remember, though, that the average metal roof lasts much longer than an asphalt shingle roof. The cost of a metal roof is determined by the location, size, and type of house. As of 2024, the average cost of a metal roof is about $12,000.

Noise

Metal roofs can be loud during rainstorms or hail. It's a simple fact that any object falling on a metal roof will be louder than objects falling on an asphalt shingle or wood shake roof. Modern installation processes can insulate somewhat against this noise, though, and over time, owners of metal roofs seldom view this as a serious disadvantage.

Performance

Metal roofs can fade in time or may be susceptible to staining. While it is highly unlikely and very difficult to dent a metal roof, it is a possibility, however, that can be easily fixed.

Installation

If not installed correctly, metal roofs can fail at the seams. It's essential to have a metal roof installed by a qualified, experienced contractor. Metal roofs are not accepted by some HOAs mainly because they are not aesthetically pleasing.

Safety

Metal roofs are indeed slippery when wet or when covered with snow. It is never a good idea to climb on a metal roof when it is moist or covered with snow. They are so slippery that snow "avalanching" off the roof is a definite hazard in areas that experience heavy snowfalls in winter.

In ski areas notorious for heavy snowfalls, metal roofs are often equipped with snow guards—metal or plastic clips or even horizontal bars mounted to sturdy brackets. Homeowners can employ the same technology to prevent avalanches from the roofs of their homes.

Are Metal Roofs Worth It?

When deciding whether or not to get a metal roof, you should consider the cost, longevity, and maintenance. Metal roofs are long-lasting, environmentally friendly, and more durable than your standard asphalt roof. However, they are slippery, can be difficult to install properly, and may be noisy during a thunderstorm or windy weather. One of the "disadvantages" of a metal roof turns out to be an advantage when viewed from the big picture. Although initially much more expensive than an asphalt shingle roof (for example), a metal roof lasts much, much longer, and in the final measure is usually the better investment.
