Cathedral roof venting deep dive and demo

Last year, we demonstrated the Wingnut Roof Vent Testing on a small demonstration rig. Although the two-by-four easel rig revealed quite a bit about cathedral roof venting, it brought up the question of how it compares to real roofs. This session will show you how the demo rig has been improved. You will witness a theatrical fogger demo that will reveal what happens on real roofs for vented cathedral roof assemblies. You will understand how roof slope, depth of vent chute, orientation, and type of ridge vent all affect if and how much air is actually venting.
