We are seeing many more houses with metal roofs while shopping for a new home. This is in northern Alabama area. I’ve owned 4 houses in the past and all had traditional shingle roofs. I know nothing about metal roofs but they look good and would seem to be a great long term value since I would assume they never need replacing. Does anyone have a metal roof and do they require maintenance like a shingle roof? Are they more energy efficient? I’m guessing if there is a hard rain or hail it would be loud.
