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!
