If you are thinking about installing a metal roof on your property, it is important to know what makes this type of roof a good choice. There are several factors you should consider, including cost, service life, and maintenance.

Service life

Galvanized roofing is known for durability. It can last up to fifty years with proper installation and maintenance. The materials used in this type of roofing have some drawbacks, however. Using blacktop shingles, for instance, can reduce its lifespan by a large margin.

There are many types of substrates and panels to choose from. The most important thing to remember is that every roof panel goes through a fair amount of wear and tear from the elements. Taking the time to properly inspect the roof on a regular basis can help prevent premature corrosion from occurring.

Choosing the right steel sheet thickness is also essential to ensuring the success of your construction project. In addition, a brisk yearly inspection of your galvanised metal roof will help to keep it in top shape.

As for the longevity of your roofing system, the amount of time a properly installed galvanized roofing system will last is dependent on several factors. This includes the quality of the steel, as well as local weather conditions. If you have a high or extremely cold climate, your roof will rust at a much faster rate than if you were to live in a warm, humid environment. Also, the best way to protect your galvanised metal roof is to avoid allowing debris to collect on it. For example, trimming your trees and shrubbery will reduce the chances of branches contacting the roof.

A properly installed galvanized roofing system will last between thirty and fifty years, and it isn’t uncommon to find some of these systems lasting closer to one hundred. However, it is best to get the pros involved if you’re in the market for a new roof.

Corrosion resistance

Galvanized roofing is a type of roofing system that has good corrosion resistance. This type of roof is highly durable and is resistant to rust, corrosive agents, saltwater, and ultraviolet rays. However, it is not without its disadvantages.

Galvanized metal is a steel alloy that is coated with a protective zinc coating. This layer of protection is applied through a hot-dip galvanizing process.

In addition, galvanized materials are usually cheaper than Galvalume, so you can save money. The downside is that the metal is not self-healing. If it is scratched, the rust will eat away at the metal, which will not function properly.

Galvanized products are not typically covered by warranties. Nevertheless, the material has a life span of up to 50 years or more. As long as you apply the right installation techniques, you should have no problems.

Depending on where you live, you may be at risk for accelerated corrosion. Coastal environments, especially those near the ocean, increase the chance of corrosion. Several materials are more susceptible than others, including aluminum, copper, magnesium, and lead.

You can use Galvalume in high-precipitation areas, but you should avoid using the coating in coastal locations. For example, Galvalume will not be able to stand up to marshes or large bays. Also, accelerated corrosion will shorten the lifespan of Galvalume Plus products.

In some cases, some specifiers choose to reduce the thickness of the metallic coating. Though not advisable, this practice is an option for some.

Aluminum is a more corrosion-resistant material than steel. However, it does not have the strength of steel. Copper flashings are easy to solder, and they are corrosion-resistant.

Choosing the appropriate type of metal for your roof is important. Most metal roofing products are made from a zinc-aluminum alloy. Alternatively, you can choose a Galvalume or another coated metal.


The cost of galvanized roofing can vary a lot. A basic metal roof can range from a few dollars per square foot to a couple hundred dollars. This is a huge price tag, especially if you want to install a heavier, more expensive metal. Fortunately, there are a few things to keep in mind before you spend a fortune on the latest roofing technology.

The most expensive material you can use for your roof is copper, which can cost between $35,700 and $68K for a full installation. However, this is also one of the sturdiest types, meaning it should last for years to come.

Galvalume is another goodie. It’s a metal coated with zinc and aluminum to prevent corrosion. Depending on your budget, this may be the material for your next roof replacement. You might even be able to find a supplier that offers a multi-year warranty on their product.

Lastly, you might want to consider some of the more expensive options, such as stainless steel or aluminum. Both of these materials are durable, but you might want to think twice before you commit to one of these. Regardless of your roofing needs, be sure to ask your contractor about the costs of installing and maintaining your new material.

Of course, there’s also the cost of replacing the chimneys and vent stacks from your older home. Luckily, most roofing companies offer free quotes based on your specific needs. If you’re looking for a roof that will last for decades, a metal shingle is a wise choice. Metal shingles are a relatively inexpensive way to go, but they will require some maintenance to ensure they’re functioning properly.

When it comes to the cost of installing a new roof, the most important thing to remember is to take the time to compare prices from multiple contractors. In the end, the cost of the roofing material will be a small fraction of the overall cost of the project.

Self-healing characteristic

Galvanized steel is an excellent roofing material. It is corrosion resistant and durable. With a few repairs, a galvanized metal roof can last for up to 50 years.

Aside from its durability, galvanized steel is also energy efficient. However, there is a downside to this material. If exposed to animal urine, it will degrade quickly. This is not a structural problem, but it is aesthetically unpleasant.

In order to prevent this from happening, you should consider installing Galvalume. Galvalume is a combination of zinc and aluminum. The mixture provides the strength and corrosion resistance of aluminum with the toughness of zinc. These characteristics make it ideal for hot and humid regions, as well as hurricane-prone areas.

A study conducted by the Metal Construction Association has found that Galvalume roofs can last as long as 40 to 50 years without any extreme signs of corrosion. Some manufacturers even provide a warranty of up to 20 years.

Self-healing composites are materials that are designed to auto-repair damage. They repair cracks and other defects and return mechanical properties to the structures.

The self-healing concept has been applied to various fields, including metal matrix composites, cementitious composites, and resistant fabrics. It can improve the life of materials, as well as the cost of manufacturing them.

There are three basic methods of self-healing. Those methods can be classified into intrinsic and extrinsic. Intrinsic healing refers to the use of reversible crosslinking bonds. Extrinsic healing, on the other hand, involves the use of a variety of materials.

Both types of self-healing methods can be applied to a variety of applications. Repair procedures are typically performed under extreme conditions. Although the concept is still in development, the use of these materials is expected to expand over time.


Having a metal roof is a sign of quality and longevity. However, it does require some maintenance to maintain its top-notch look. A few small changes here and there can keep your roof looking as good as the day you bought it. Here are a few simple tips to get your metal roof on the right track.

The first rule of thumb is to always inspect the roof for signs of damage. Even minor scratches are easily remedied with a decent quality paint pen. This will prevent small nicks from turning into major dents in no time at all. If you are lucky enough to live in a climate that experiences a bit of hail storm activity, make sure you are paying attention to the finer points of storm-proofing.

For the most part, the best way to care for your roof is to avoid climbing on it. Instead, consider hiring a professional to perform routine maintenance and replacements. Not only is this a smart move, but it can save you a bundle in the long run.

A properly maintained metal roof is a worthwhile investment. Metal is a durable and eco-friendly material, and it can protect your home for years to come. However, it does require regular maintenance to ensure the longevity of its many components. By following a few simple guidelines, you can ensure your roof stays in tip-top shape for decades to come. Among the tips to remember are: Always use a soft bristle brush when washing the roof. Be sure to avoid scouring pads and wire brushes.

It is also important to perform a proper maintenance check before the big freeze. While you are at it, pay special attention to the gutters and downspouts. Make sure they are in working order, and replace the clogged ones as needed.
