Are rusty nails normal or can they be a sign of damage to your roof?
Professional roofers should be using a special kind of nail that has been galvanized. Galvanizing is a process that makes stainless steel resistant to rust by coating it in a layer of zinc, which doesn’t rust. Galvanization is very important when it comes to roofing nails, and if you have nails that are showing signs of rust you could be in for some bad news.
Rusty nails on your roof or in your attic are most likely a sign that water is getting in one way or another. If you see rusty nails, pay close attention to the surrounding areas, this small issue could eventually lead to bigger issues.
