This one was personal. The homeowner is my best friend's mom, and her goal was straightforward: pass this house down to her son and make sure he never has to buy a roof. We installed a mechanically seamed standing seam system in Black Frost. No exposed fasteners. Panels seamed shut with a machine, not screwed down with rubber washers that fail and start leaking a decade in. This is a 50 to 70 year system with a lifetime non-prorated transferable warranty, which means it goes to him when the house does. Most people re-roof three or four times over the life of a home. She did it once and took it off the list permanently. That is what a 4Ever roof is for.
