Metal Roof Materials

"Metal roof" is a generic term that refers to many different types of roofs. Common metals used in roofing include: 

• Steel
• Aluminum
• Copper
• Zinc 

All of these materials are durable roofing options. There are distinct attributes and drawbacks of each to consider though. 

Steel 

There are two main types of steel roofs. Stainless steel is highly durable, resistant to corrosion, and aesthetically stunning. However, it can be much more expensive than almost any other option on this list. 

The second type is steel roofing made of steel but coated with zinc--"galvanized" steel--tin, or an aluminum-zinc allow. These coatings enhance the metal's corrosion resistance while keeping the price down. This version of steel is one of the most popular roofing material options. 

Aluminum

Aluminum is perhaps the second most common metal roofing type. It is extremely lightweight and is naturally corrosion-resistant. This makes it a popular choice for buildings located on the coast or otherwise near salt water. 

Copper

Copper roofing has a distinct appearance, developing a beautiful patina over time, which gives it a distinct look but also helps keep it from rusting. It will last for 80 to 100 years or more. Copper can be more expensive than other roofing types, and--while strong--it is susceptible to denting. 

Zinc

Zinc roofing is also very attractive and will last a lifetime. It is on the expensive side. Also, once it patinas and turns a blue-gray color, it can develop a chalky residue in areas where water runs from the roof. 

What Makes Metal Roofing Last So Long?

Several characteristics make metal roofs last for decades. These include:

Material strength

Weather resistance

Corrosion resistance

Low Maintenance

Installation features

All of the metals mentioned in the section above are exceedingly strong. They can resist falling limbs, strong winds, hail, and other threats. Metal roofs are not flammable, which gives the building an added layer of fire protection. 

High-quality metal roofs will not rust or corrode. Unlike organic materials, such as wood, metal is not susceptible to rot or decay. 

Insects and rodents cannot damage it, and mold cannot live on it. This also makes it easy to clean (versus other roofing materials), making for simple metal roof maintenance. 

Beyond the metal material itself, there are some metal roof features that also contribute to its longevity. Metal roofs have secure fasteners, that--unlike various types of shingles--make them resistant to wind. They are almost impossible to dislodge. 

Metal Roofing Benefit 

There are many other distinct advantages of metal roofs to consider. These include:

Durability and longevity

Energy efficiency

Low maintenance

Limited environmental impact

Aesthetic appeal

Increased property values

As mentioned, metal roofs are very strong. With proper installation and maintenance, they are one of the best long-lasting roofing solutions. 

Metal roofs are very energy efficient. They reflect solar heat, helping keep the building cooler in the summer. This can save homeowners a great deal on energy costs. 

Metal roofs require very little maintenance. They should be cleaned occasionally, and minor repairs are typically easy to address. 

Another major advantage of metal roofs is that they are environmentally friendly. Since they last so long, they offset the need for more frequent replacement materials common with other types of roofs. Metal is also highly recyclable, which contributes to sustainability. 

Metal roofs are great looking. They come in a variety of styles and finishes, so you can tailor the look to your home. Finally, all of these attributes can significantly increase the value of your home, making a metal roof a solid investment. 

Are There Any Downsides to Metal Roofs? 

There are a few minor drawbacks to metal roofs, although the pros far outweigh the cons. The main one is that they cost more. However, if you take their longevity into account, they can have a much lower per-year cost than almost any other roofing material. 

As mentioned, some materials, like aluminum and copper, are susceptible to denting. This usually requires a fairly violent impact. Also, replacing or repairing dented surfaces is pretty straightforward and inexpensive. 

Metal roofs can be noisier during rain or hailstorms. However, proper insulation and underlayment can significantly reduce the noise they produce. (Many people find the light sound of rain on the roof to be soothing.) 

Some metal roofs can develop slight ripples or waves, known as "oil canning." This is a result of temperature fluctuations and the expansion or contraction of the metal. This is a minor cosmetic issue that does not impact the strength or performance of the roof. 

Finally, metal roof installation can be more difficult and take longer than traditional roofs. It does require specialized skills and expertise, which makes it crucial to hire qualified, experienced roofing contractors.
