A metal roof is an excellent choice for any home. Metal roofs have a long life expectancy — some over 50 years. Their durability and low maintenance make them a popular choice for homeowners for decades. Metal roofs today are more popular because of cool roof coatings, which make them energy efficient.
The most important decision that you will have to make if you decide that a metal roof is the right choice for you is which type of metal roof you want. Here are the pros and cons for four common types of metal roofing:
Aluminum is without a doubt the most popular type of metal roof available today. Aluminum is lightweight and durable. It can also resist corrosion, making it the ideal choice for almost any home. Pre-painted aluminum roofing materials are common today. The manufacturer offers a wide range of options, and the metal arrives at your roofer ready to be installed.
Aluminum is an easy material to make. Most roofing aluminum is made from post-consumer recycled products so it is also a good choice for a metal roof. Aluminum can be made in almost any profile or shape you like, including aluminum shakes and shingles or traditional standing-seam metal roofing.
Aluminum metal roofs are expensive. Aluminum roofs are more expensive than traditional asphalt roofs, even though they’re not as costly as zinc or copper. The upfront cost of an aluminum roof is often more expensive than the total roof cost due to its longer lifespan.
A copper metal roof is a great choice if you want a bold and beautiful look. This kind of metal roof is a classic. Copper is known for its beauty and attractive blue-green patina that it develops when exposed to the elements. Copper roofs are extremely durable, but there are some drawbacks.
Copper roofs are expensive. Copper roofing can be expensive so homeowners often choose to have a small amount of copper roofing applied on their porches or as an accent roofing like a dormer. Copper can streak and stain other materials, so be careful where copper roofing is to be installed.
Zinc is another durable metal roof. Zinc, like copper, will develop a patina over time. This makes it more durable and less likely to rust. Zinc is very easy to make with less energy than other materials due to its low melting point. Energy efficiency is important if you are looking for green roofing options. Zinc can also be recycled 100%. Zinc doesn’t have to be coated as aluminum so it won’t affect the original material. You could even recycle your old roofing materials if you had to re-roof. However, this would be a lengthy process.
It’s easy to see that zinc is a popular metal roof type. However, there are some drawbacks. Zinc is expensive to install, just like copper. A specialized roof crew is required and the material itself can be very expensive. Zinc is also a soft metal so it won’t withstand hail as well as other options.
Steel roofing is a long-standing commercial roof option. However, it’s now becoming more popular for homeowners. Steel is an alloy. This means that it contains iron and other elements. Steel, which is also used in heavy-duty construction aspects, is extremely durable. This is also the most affordable metal roofing material. Steel is made from recycled materials and is an excellent choice for many. Steel rusts. This is the biggest problem. Steel roofing materials can be manufactured in three ways to combat this problem:
Galvanized Steel Roof – This is the most popular type of steel roofing. It uses a zinc layer to protect the steel underneath from corroding.
Galvalume Metal Roofing – Instead of using zinc coatings, galvalume steel uses an aluminum/zinc combination to protect the roofing’s inner steel layer. Aluminum offers greater corrosion protection and gives the product a uniform appearance.
Weathering Steel Roof – One layer of steel makes weathering steel the least used type of steel roofing material. The outer layer protects the inner layer from rust and is intended to rust. This type of metal roof is intended to rust and is usually used to add character to a home.
There are many types of metal roofs, including aluminum, copper, zinc and steel. The look you want, your budget, and the environment you live in will all play a role in choosing the right metal roofing for you. We’re happy to assist you once you have made your decision.
