What is Stone-Coated Metal Roofing and Other Types of Metal Roofs

Metal roofs are one of the top choices of roofing materials in the Philippines. They’re durable, affordable, and low maintenance. However, there are different types of metal roofing with different characteristics and benefits.

It’s important to know the different metal roofing materials so you can choose the ideal metal type for your house or other projects. So, in this blog, we’ll discuss and differentiate the five different types of metal roofs available and give some pointers for choosing the right materials.

What are the Different Types of Metal Roof Panels?

In general, metal roofs are a great choice of roofing material. They’re lightweight, durable, and easier to maintain than other types of roofs. Among these different types of metal roofs, which is the best choice?

Stone-Coated Steel

Stone-coated metal roofing has a steel base that is covered with multiple protective layers, including stone granules. The protective layers make this material weather-, corrosion-, and fire-resistant. Stone-coated metal roof has a life expectancy of up to 50 years, with minimal upkeep.

This type of roof also comes in a variety of designs and finishes so it has great curb appeal. It usually comes in tiles so while it is on the heavy side, it’s still easy to transport and install.

Depending on your supplier of classic stone-coated metal roof tiles, you can choose from a variety of designs and finishes, all of which offer great curb appeal. It is also on the mid-range price point.

• Pros: affordable, durable, strong, minimal upkeep, style options
• Cons: requires experienced contractor for installation

Aluminum

Aluminum roof is one of the lightest materials available. As a result, it’s very easy to install, often not requiring heavy machinery. Despite its light weight, it is durable and corrosion-resistant, making it a great choice for houses or buildings in coastal areas.

Aluminum is also a malleable material so it can easily fit different structures. However, malleability comes with a price. Aluminum is more prone to denting if debris or rock falls on it. Heavier and thicker aluminum roofs are more resistant to denting but they also tend to be pricier.

In general, aluminum roofs are more affordable than copper and zinc roofing. The price of aluminum roof goes higher as the material becomes thicker and more durable.

• Pros: lightweight, durable, malleable, corrosion-resistant, mid-range price
• Cons: easily dents, higher price for stronger materials

Zinc

Another type of metal roof is Zinc. Zinc roofing offers considerable durability, often lasting up to 30 years.

After around three years, zinc roofs develop a patina, which could be blue or gray depending on the environment. The patina helps protect the roof from scratches and corrosion. Furthermore, while the patina gives roofs a nice finish, it leaves a chalky residue.

Zinc requires minimal maintenance since it is corrosion- and fire-resistant. However, a disadvantage of zinc is its hefty price. It can be a smart investment if the budget allows.

• Pros: durable, corrosion- and fire-resistant, minimal upkeep
• Cons: creates a chalky residue, pricey

Copper

Copper is another lightweight and durable material that was most used as roofing material in ancient times until the medieval times. It was used in the Lovamahapaya in Sri Lanka and in the Pantheon in ancient Rome because of its long life, light weight making it easy to install, corrosion resistance, and overall attractiveness.

Nowadays, copper roof is mostly seen only in buildings, mostly historical ones though a few modern buildings do use this material. While copper can last for hundreds of years, and develops a nice patina over time, it does dent easily. It’s also expensive and rare.

• Pros: extremely long lifespan, minimal upkeep, lightweight
• Cons: expensive

Galvanized Steel

Galvanized steel means that the iron sheet has been covered with a protective layer of zinc to prevent corrosion. However, rust may become a problem if even a small part of the zinc coating comes off. Rust may quickly spread through the material, so it’s not the best option for coastal areas.

If you can prevent rust from developing, galvanized steel roofs can last up to 20 years. It’s very malleable as well and comes in different colors. Moreover, this type of roof is the most affordable of all metal roofs.

• Pros: affordable, malleable, color options
• Cons: not completely rust-resistant, shorter lifespan than other metal roofs
