Different Types of Metal for Your Roof

If you thought all metal roofs are made of the same type of metal, you’re sorely mistaken! In fact, roofs can be made from several different kinds of metal, each of which has its own advantages and disadvantages. Continue reading to learn more about the different types of metal, and which are the best for metal roofing in Alaska.


Its resistance to rust and corrosion as well as its durability make aluminum an excellent choice for both homes and businesses. Additionally, aluminum can be painted in any color you can imagine. Anyone who cares about recycling will also be happy to know that aluminum roofs can be made of up to 95 percent recycled aluminum—it’s great for your home and Mother Nature alike!

Though it is resistant to rust and corrosion, aluminum is more susceptible to hail damage than other types of roofs. Aluminum is also a bit more expensive than other types of metal, but its longevity makes it worth it in the long run.

Galvalume steel

A galvalume steel roof is a steel roof that’s coated with an alloy of aluminum and zinc. This alloy amplifies both the positive and negative qualities of aluminum. For example, galvalume steel roofs are incredibly corrosion resistant, but on the other hand, they’re also more susceptible to scratches and cracks than some other types of metal roofs in Alaska. Unfortunately, when moisture gets inside those cracks, the metal can start to rust and become stained. We recommend using galvalume steel for a simpler profile roof that doesn’t have very many bends or seams, as this is where staining is more likely to occur.

Galvanized steel

Where galvalume steel is coated with aluminum, galvanized steel is coated with zinc. Galvanized steel is the most popular option for metal roofing in Alaska. It’s less expensive than other metals, it’s strong as can be and the zinc coating holds paint really well. The only downside of this type of roof is that if it’s not installed correctly, it could start to rust prematurely. So, be sure that you hire a trusted professional to install your new roof!


If you’re looking to have the best looking roof on the block, copper ought to be your go-to roofing material. Unfortunately, copper is also incredibly expensive, so you’ll probably never see a roof that’s entirely made of copper. Instead, many people use copper for the trim to elevate the look of their roof. Copper can also be used for flashing to protect parts of your roof from water damage. We don’t advise using copper for trim or flashing if you have a metal roof, though. Two metals that are in contact with one another 24/7, 365 days a year tend to rust or corrode much faster than they would otherwise.
