Anyone have any recommendations on standing seam metal roofs? Recommended brands? Thickness? I am going to replace the 39 year old roof on my cabin. It has had a few leaks here and there that I have patched over the years but roof is steep and I am not getting any younger. I'd rather not deal with patching anymore. I'd like to buy something that will last a minimum of 30-40 years that has the greatest resistance to moisture penetration. It can also have a couple feet of snow on it during the winter. This Series 300 looked interesting... I will be hiring a contractor for this. That will be the next challenge after identifying replacement materials. I'm going for the long haul so not looking for cheapest material either. Thanks!
