The biggest downside though is that it is prone to rust. To answer this problem, steel manufacturers decided to make galvanized corrugated metal roofing. This happens when the metal undergoes a chemical process to prevent it from corroding. The key ingredient in this process is zinc which results in the fabrication of a coat over the original metal.
After the metal is coated, you get to have zinc on top, the metal in the middle and zinc again in the bottom. It is like making a sandwich and instead of eating it, this is what you buy and put on your roof so water does not drip in the house when it rains.
You will notice that it is not that noisy outside when you use it for your home. Surprisingly, it only produces the same amount of noise as asphalt, clay or wood.
