I am a licensed builder. A metal roof is good in some situations but bad in others. Also if the pitch is low, metal roofs are not good, I feel six
twelve is the minimum pitch for them so the water does not pool
My big problem with them is that snow falling off of them is heavy and dangerous if you are walking under it. I have seen lots of damage to cars and
people from that falling snow. It also can damage a lower roof. If you are in a high wind area, those sheets can get ripped right off and cut
someone's head off. I prefer shingles myself, a good quality shingle will last thirty years or more depending on the conditions in your area. I am
getting mine redone, I do not do much with construction anymore because of my epilepsy, and I am putting Certainteed Landmarks on, they seem to have a
decent lifespan. There are different types of them, getting the right one for your condition in the area is relevant. My last shingles lasted twenty
nine years, I am replacing them before the leaks. In another thirty years I will have been buried for a while, let someone else worry about them.
I would only put metal on a barn or shed where you do not have to go in from under the eve at all. You cannot park on the side of the garage if the
snow is coming down, can't store stuff under the eve either, it will mess stuff up when it comes crashing down, even break the shovels handles.
Metal roofs also sweat on the underside of the metal certain times of the year and can cause problems if there is not a good barrier underneath
sometimes. If I was going to put a metal roof on, I would use the standing rib type with the blind nailing and every rib is sealed.
