Ventilation baffles over lean-to?
My father is building a detached garage, and we are planning to put insulation in the ceiling within the next couple weeks. I know that we will need ventilation baffles on one side where the roof meets the walls. But on the other side, the roof has a lower slope and forms a lean-to. When I talked with the builder today, he said that we don’t need to install ventilation baffles on that side, as there is adequate space between where the top of the insulation will be and the rafters. Can I trust his judgment?
