![]() You will want to avoid cleaning the rust yourself, however, as this may invalidate your warranty, losing you money. In those cases, your roof should still be under warranty. Though metal roofers take careful measures to prevent rusting, sometimes harsh weather can strip away the protective coating and damage the metal. This offers similar rust resistance as galvanized steel, but with the added appeal of a stone appearance. Some roofers, such as Erie Metal Roofs, use stone-coated steel. Galvalume steel, on the other hand, can last as long as the metal in the most humid of climates.Īside from the material itself, most metal roofs are painted, and this provides a protective coat that prevents rust as well. When you see an old, rusty metal roof, it’s usually an older galvanized design. This material is stronger than ordinary galvanized steel – lasting up to three times longer against rust. This coating protects against rusting, while preserving the structural strength of the inner steel layer.Įven more common today is galvalume steel – which is protected by an aluminum and zinc alloy. Steel roofing is great for rust resistance and has an outer coating of zinc – protecting most iron content in the material. ![]() While copper is certainly a choice, galvanized steel is far more common. That said, most roofers don’t use pure iron or unprotected copper for their materials. Two metals are highly vulnerable: copper and iron. First, not all metals rust for rust to occur, metals must combine with oxygen and water to form different oxide chemicals, most commonly iron oxide. It comes down to picking the right metal for the job. That’s why manufacturers engineer metal roofing obsessively to prevent the risk altogether. Keep in mind that roofers are well aware of the rust factor when it comes to metal roofs. This is partially why metal roofs do not rust easily, as they are immune to many other forms of rot. Being naturally waterproof, metal sheds rainwater quickly and does not develop mildew or mold. Metal roofing is resistant to most forms of decay. Why shouldn’t the same be true for a metal roof? As it happens, manufacturers engineer metal roofing specifically to avoid rust, much longer than one might otherwise expect. Even a durable car – particularly in the north, with salt on the roads – will decay. It does not store any personal data.We all know that metal rusts, and we also know that rust can weaken or destroy metal structures over time.
