Painted Metal Roofs vs Unpainted

Painted Metal Roofs vs Unpainted

Why does a metal roof from Buy Metal Roofing Direct last so long?

There’s a couple of things you need to know to get a proper answer to that question. We like using Galvalume substrate for mill finish, and if we paint that Galvalume, we use top quality Sherwin-Williams Industrial Paint specifically designed for the riggers of a roof application.

AZ55 Galvalume, mill finish, acrylic coated is what we use to manufacture at Buy Metal Roofing Direct. AZ55 is the Galvalume thickness required to carry a 25-year warranty. As stated by some of the world’s leading steel companies Glavalume has, “at least twice the corrosion resistance over galvanized coatings of the same thickness and excellent corrosion resistance at cut edges."

Mill finish Galvalume can provide at least 35 years of performance before requiring major maintenance, while the full-service life can be 40 – 60 years.

Now let’s coat it with some industrial strength Sherwin-Williams Energy Star paint systems and see what we get. By the way Energy Star deserves its own discussion. So we’ll cover that in anther blog. Warranties for fade and chalk are 30 years, and that tells us you’ll still have nice color on your roof far into the future. Our paint system allows for 7 units of fade and that’s over a 30 year period. Hope I can add 30 years and still look that good! And that will save you money on power bills for many years in the future.

At Buy Metal Roofing Direct, we love Sherwin-Williams proven long lasting paint systems that last 40 – 60 years, or lifetime.

If your budget will allow it, painted metal roofing panels from Buy Metal Roofing Direct will give you greater energy efficiency, and energy dollar savings, over time as compared to mill finish gavalume panels.
