Homeowners find it necessary to replace or buy a new roof over their homes. Thus, corrugated metal roofing would be a good choice. Corrugated metal roofing is popular among building owners these days as it is one of the most popular kinds of metal roofing. It can be used in different kinds of applications.

This article will share the advantages of this type of metal roofing and the types of metal roofings that are available.

What is Corrugated Metal Roofing?

Corrugated metal roofing is distinguished by its wavy pattern. It is formed by metal sheets that are shaped into a corrugated design. Residential and commercial buildings use it because of its unique appearance.

The corrugated design contributes to the visual appeal, strength, and rigidity of the roof. The waves allow the sheets to cover longer distances compared to flat metal sheets. The process of preventing water accumulation is that corrugations drain by channeling rainwater runoff to decrease the risk of mold growth on the roof surface.

The combination of durability and affordability can be seen in corrugated panels.

The depth of corrugations influences the strength of the panel. Thus, a deeper corrugation improves strength.

There are different sizes of corrugated metal panels and these include ¾”, ½”, and ¼” sizes. The value shows the depth of the corrugations.

Kinds of Metal

The metal type, commonly known as the substrate, dictates the roof’s longevity. Most building owners choose aluminum or steel for being cost-effective. Copper and zinc are also other premium materials. There are different factors that influence the longevity of metal roofing. These include the quality of installation, maintenance, and environmental conditions. Steel and aluminum have an average of 30 to 50 years as their lifespan while it takes 80 years for copper and zinc to deteriorate.

The following shows the characteristics of each metal.

Galvanized steel

Galvanized or zinc-coated steel is among the best choices because it is cheaper compared to other metals and is durable.

Galvanized steel can be classified based on the thickness of its protective zinc coating which is indicated with a “coating weight” by manufacturers. An example would be that heavy-coated G100 steel will be more rust-resistant than lighter-coated G90 steel. This shows that a G100 galvanized steel would be more expensive than G90 steel.

It gets quicker for exposed steel to rust. It is smart to invest in heavier galvanized coatings to extend the lifespan of the roof. Galvalume and stainless steel are more expensive but take longer to rust than galvanized steel.

Aluminum

Aluminum is another cost-effective choice. The best advantage is that it does not rust like steel which is suitable in humid, coastal climates. Aluminum corrugated panel is perfect for such climate conditions. Another advantage is that aluminum is lighter than steel which makes it better to use over an existing roofing material. Lightweight aluminum allows installers to install more easily and puts less stress on the structure.

Zinc

Zinc is perfect for homeowners who never want to buy a replacement roof. A zinc roof can extend up to 80 years. Its natural patina protects the metal from rust. However, it is much more expensive to buy zinc compared to galvanized steel or aluminum.

Copper

The most expensive is copper. It can last up to a hundred years and can withstand the best in the roofing industry. Copper also becomes blue-green after a number of years of exposure to the elements.

Benefits of Corrugated Metal Roofing

Corrugated metal roofing obtained a good reputation as an attractive and reliable roofing solution. This has captivated homeowners and builders alike. Here are the key benefits that make this roofing stand out among its peers.

Durability and Longevity

Corrugated metal roofing has a design that allows it to withstand harsh weather conditions. This prevents the wear and tear of the roof. It also provides a longer lifespan compared to conventional materials like asphalt shingles and concrete tiles. With regular maintenance, corrugated metal can stay up to 70 years which can give owners peace of mind.

Low Maintenance

Corrugated metal roofing has a smooth, non-porous surface that easily sheds debris, dirt, and leaves to minimize manual cleaning. The resistance of metal to the growth of mold and mildew further reduces maintenance compared to organic materials like shingles which easily trap moisture and deteriorate.

Although it is not essential to conduct regular maintenance, occasional cleaning with a mild detergent solution and gentle rinse can remove dust or grime that accumulated. This ensures optimal appearance and performance for years.

Lightweight and Easy to Install

Corrugated metal lessens the stress on the underlying structure of the building. This increases the lifespan of the roof as a lighter material simplifies the installation process. The decrease in weight also lessens the load on the framework of the building. This is significant in areas where there is seismic activity or specific structural limitations.

Conclusion

Corrugated metal roofing has numerous advantages. One type is aluminum corrugated panel which also stands out among its peers. It is durable, has a longer lifespan, and requires low maintenance.
