The contractor bought the materials. I deal with them directly. See my last post. Our issues are rotted wood fascia, fly rafters, and Cornice brackets that they just want to cover in metal without any rotted wood repair first. We put the brakes on that part of the repair because they weren't interested in repairing before covering. The exposed rafters on the garage need replaced and must be done before the roof is installed. They are attached to the underside of the roof decking. I asked a few times about the metal covering procedure and the best answer is that it comes off a coil and is hand bent under the exposed rafters. It didn't sound like a quality job to me. He needed to get his framers and metal workers out here to look at what needs done and make a plan. Show me how it is done and will look before I spend thousands to do it.
