bolded textHad to replace my shingled roof after Hurricane Ian. I decided to pay the difference and go with a metal (aluminum) roof. I told the roofing contractor I wanted a roof with a mill finish. He guided me to his suppliers website where I picked the standing seam, and I assumed all of the choices I was seeing were aluminum. I saw 26 GA. GALVALUME, .032" ALUMINUM above the selection I made. Six days into the installation I found out my roof is steel, not aluminum. It's Galvalume, which I had no idea what that was. Before, I get too excited about having a steel roof in SW Florida (and my house is on a brackish canal). Is this Galvalume as good as aluminum? Will it withstand the salt air? Is Galvalume cheaper than aluminum (I have not paid the final payment yet?

You will get a variety of answers to those questions. Also, some manufacturers in Florida are offering very strong warranties on Galvalume even in coastal applications, so I would ask about warranty. .032" aluminum is not commonly offered in unpainted or clear coated. That is something they really should have pointed out in their explanation, in my opinion. What it sounds like you have is clear-coated Galvalume. Again, you will get a variety of answers to your questions. My recommendation for installations on salt or brackish water is painted aluminum. Most manufacturers offer a silver color in painted aluminum. Aluminum is typically quite a bit higher priced than Galvalume. My guess is you were priced for Galvalume not aluminum -- again, just my guess.
