Galvalume Vs. Painted Metal Roof

 Building your home has many factors to consider, especially when it comes to roofing. Each roofing material has its unique features that you have to study. Which is better, a Galvalume coated roofing or a painted metal roof? Read our post to determine which roofing choices suit your taste and budget.

What Is Galvalume Roof? 

Galvalume roof is coated with 55 percent zinc and aluminum alloy with the remaining percentage of silicon. The combination of these chemical elements provides ample protection from oxidation. It works similarly with the galvanized roof.

The coating on the metal sheet can extend the life of your roof for up to 60 years with minimum repair and maintenance every year. Non-coated metal roofing does not last longer compared to the Galvalume roof.

The corrosion-resistant characteristics of Galvalume make it an ideal roofing choice if you want to save your dollars.

What Is A Painted Metal Roof?

A painted metal roof is a type of metal sheet with paint coatings. This type of roof is corrosion-resistant and can withstand the elements and sun. The paint coating adds a layer of protection and longevity to your roofing.

Painted metal roofs are sturdy and insulate your home from UV rays, although it is less effective than Galvalume. Since a painted metal roof is prone to fading, you must repaint it every ten years to extend its life.

Comparing The Galvalume Vs. Painted Metal Roof

Galvalume roofs and painted metal roofs are both metal roofs. A painted metal roof is coated with paint, while Galvalume has an alloy of zinc, aluminum, and silicone coatings.

The surface of Galvalume has a rough texture, making it easy to absorb heat because it is less reflective, which can help save your monthly electricity consumption.

Galvalume is less expensive because it requires less maintenance than a painted metal roof. If you live in a coastal area, choose a painted metal roof because it can withstand corrosion from saltwater.

Maintenance of your building materials is vital to save your home from wear and tear. Galvalume requires less maintenance and repair than painted metal roofing.

The paint may fade from direct sunlight, while Galvalume treatment gives the roof longevity that could last for over 60 years.

Drawbacks Of Galvalume

A painted metal roof works better for this structure.
