A metal roof is typically a roofing structure made of metal tiles or pieces characterized by their high flexibility, durability and strength. This is part of the building envelope usually attached to the house. Steel, zinc and copper alloys are common. Some roofs are also made from aluminum while others are made out of copper alloys. Metal roofing materials come in a variety of metals such as aluminum, copper, galvanized steel, galvanized aluminum, fiberglass, tin, steel, zinc, wood, melamine and many more.
The use of a metal roof has increased tremendously over the years due to its durability and low maintenance. Metal is corrosion resistant and dust proof which makes it ideal for indoor use. It can also withstand extreme weather conditions. However, some roofing surfaces are more susceptible to damage due to algae, moss, mold and mildew. These factors are usually taken into consideration when selecting the appropriate metal for the specific area.
It is quite common for metal roofs to be made of galvanized steel. This is because galvanized steel is very durable and it does not rust. If the zinc coating is not properly applied on galvanized steel, it can easily corrode. Roofs that are made out of galvanized steel, though durable, are vulnerable to weather and erosion. There are pros and cons associated with both the advantages and disadvantages.
When comparing the pros and cons, it should be noted that metal roofs offer better protection from weather, termites and erosion. They are also rustproof and thus, they provide homeowners better protection against the occurrence of corrosion. Furthermore, they do not require frequent painting or maintenance, and thus, they are cost effective. On the other hand, they require more effort to install. Moreover, they are expensive and this may deter some homeowners from purchasing them.
Another metal roofing material that is widely used in residences today is copper. Compared to galvanized steel, copper is a cheaper alternative. This is because copper has a longer lifetime. Furthermore, it is easy to maintain and is stronger than steel.
The main disadvantage of using aluminum roofing materials is that it easily rusted or corrodes over time. It may become brittle and easily breaks. Furthermore, aluminum is quite flammable and this is why it should be used in areas that have a volatile atmosphere. If this is not provided, homeowners should invest in fireproofing the metal roof. This will prevent the fire from spreading or catching fire due to an electrical malfunction.
As the demand for metal roofing materials is increasing, more homeowners are opting to install them. Some homeowners are even going as far as to rent the equipment required in installing these roofs. However, there are also those homeowners who would rather do the installation themselves. They prefer doing the installation themselves because they find the task too hard and complex to hire someone else to do. With this in mind, it is important to know the difference between aluminum and asphalt roofing materials.
Asphalt shingles are cheaper than steel shingles, which is why they are the most popular types of metal roofing material right now. However, steel is also becoming popular because of its durability. With proper maintenance, steel can last for decades.
Other common types of residential roofing are aluminum and steel. The choice usually depends on the homeowner’s preference. Each type of material has pros and cons. One of the most obvious is the cost, which each type of material costs more to install compared to asphalt shingles.
With residential roofing, the materials used should be resistant to the elements like heat, moisture, corrosion, termites, and sunlight. Asphalt shingles are resistant to moisture because of its vapor barrier. However, asphalt shingles are vulnerable to heat and are damaged by fire. The appearance and lifespan of the metal roof is affected by the color. Colors like black, gray, white, blue, and others are not advisable for accent purposes like copper. Copper needs to be chemically treated for appearance.
When it comes to metal roof systems, there are several tips that homeowners should consider. One is choosing the right size. Another is considering the material. And the last is to consider your budget and other needs so you can make a well-informed decision.
