Why Galvalume® Makes a Great Metal Roof

Metal roofing contractors have a wide variety of metal roofing products to choose from when deciding which lines to carry and install. Industry experts with the Metal Roofing Alliance agree that it’s crucial that contractors choose those products carefully, particularly when installing metal on homes.  In order to grow the residential metal roofing market, the product has to perform well over time – what we call “Investment Grade Roofing.”

No homeowner wants to have a poor quality metal roof protecting their biggest investment.  Unfortunately, the marketplace is full of sub-par metal roofing.So how can you be sure that you’re installing the right product in the residential market?  It all starts with the substrates and coatings on the base steel.  There are a wide variety of metal roofing products available with a variety of coatings.  The two primary choices for coatings are galvanized and Galvalume®.  Learn more about galvanized coatings in our previous post here.  Read on for details about  Galvalume®.

Introduced over 40 years ago, Galvalume® is a metallic coating that has extraordinary outdoor corrosion resistance, making it ideal for use in metal roofing.  The coated panels can be readily roll-formed into a variety of panels as well as formed and stamped into tile and shingles.

According to Ken Gieseke, Vice President of Marketing at MRA member McElroy Metal, “The process of galvanizing steel entails applying a coating or molten zinc to raw steel and has literally been practiced for centuries.  Galvalume® substrates utilize a molten alloy of zinc plus aluminum.  The combination of zinc and aluminum create a steel substrate with greater resistance to corrosion and a longer service life.”

Over four decades of testing has shown that Galvalume® delivers superior corrosion resistance.  According to Gieseke, time has proven that Galvalume® steel roofs last longer, require less maintenance, and offer exceptional value.  In fact, the product performs so well that steel mills warranty it against rupture, perforation, or failure due to corrosion.

“Galvalume® sheet is an ideal material for roofing because of its extraordinary outdoor corrosion resistance,” states Dick Bus, President of the MRA and President of ATAS International.  “The MRA has been educating homeowners on the importance of finding contractors that know how to install ‘Investment Grade’ roofing products on their home.  Our website offers a wealth of information about proper installation, quality products and how to find trained contractors who know how to install metal roofing systems.”
