We haven't had any major issues really. Just slow going on the install. The factory rep was here for 2 days. Super nice giu and he was on the design team for the product when it was conceived. Oh, the crew does something out of order and they have to un-do and do over. I just hope it is all watertight when they are all done. A bead of sealer left out of a certain place could cause a major problem down the road. Like with any roofing, you need to think how the water is going to run and drain when it rains.
