This is a small detached garage in Defiance County. I replaced a piece of steel that had blown off with new ProRib (40 yr. warranty), tightly attached to the structure of the roof. I also affixed flashing along the front dormer to prevent water penetration. The flashing has been sealed with 100% silicone caulk up along the siding, as well as AST Expanding Sealant Tape (soaked in tar) down along the bottom edge. This roof is now sealed from moisture and critters!
