Metal roofing offers a number of advantages when compared to more traditional roofing materials like asphalt or wooden shingles. However, there are different types of metal roofing that are available for your property. Understanding what the differences in advantages and considerations are for three of the most common types of metal roofing materials can help you pick the one that is best suited for your building's roofing needs. 

Galvanized Steel

Galvanized steel refers to steel that is coated with a layer of zinc to protect it against corrosion. This means that galvanized steel roofs are able to enjoy the extreme durability and rugged strength of steel with the added benefit of not having to worry about holes rusting through your metal panels over time because of moisture exposure. However, galvanized steel can be quite heavy, which means that your property's roof needs to have the necessary structural supports in place to hold it up, which can be expensive to install if you don't already have them. Further, galvanized steel will not be immune to rust forever: as water removes the zinc over the years, the likelihood of spots of corrosion taking hold increases. 

Aluminum 

Aluminum is a great choice for property owners who are looking for an affordable way to enjoy the benefits and durability of metal roofing. Aluminum is completely immune from rust and corrosion damage, which can help extend its lifespan and reduce the amount of maintenance and repairs that your roof will require. Furthermore, aluminum is a lighter-weight material than other common metals used for roofing installations, which can help speed up the installation process and keep associated labor costs low. It should be noted that aluminum is fairly malleable for a metal, which means that it can become visibly dented over time with exposure to rainfall and falling debris. 

Copper

Copper is another common roofing material for both commercial and residential buildings. Copper roofs have a natural bronze shine that will eventually turn into a greenish hue with time and weather exposure, which creates an unmistakable aesthetic on the exterior of your building and is widely considered a status symbol. Copper, like aluminum, is completely immune to rust and corrosion, though is less malleable and will be able to withstand physical pressure without becoming dented or damaged as easily as aluminum. However, the image of copper as a status symbol necessarily comes with a price tag to match, which means that copper roofs may not be the best choice for properties that have a relatively restrictive roofing budget.
