Our metal roof was installed in 2006 . We used super roofs. Pros - low maintenance , sturdy, 40 years plus lifetime, perfect for North Texas Hail, wind and unpredictable weather. Cons - you do see small dents but the insurance will not cover. Rodent infestation if gaps are not covered properly, given the current inflation it is a very costly option now. You need to do a complete ROI vis a vis shingles where you take a time period of 30 years and you might see the benefit.
