We’re on day 3 trying to figure out how to put this roof in to place. Even my father, the roofer, couldn’t manage to solve the problem. The pieces will slide on on one side, but not fit accurately on the other side. You consistently get one section in on both sides and a slight movement of the panel and it pops out. For 900, we shouldn’t be trying to find a different method to make this work. I’m beyond frustrated.
