A deep dive into cathedral roof design and insulation strategy. The team compares solid-sawn rafters vs. scissor trusses, smart vapor retarders vs. poly, and discusses optimal roof pitches. You’ll learn when to vent from the topside, from below, or go unvented entirely—and why those choices matter. In the last 10 minutes, the crew unpacks one of building science’s trickiest topics: 6-sided containment of air-permeable insulation—and how it impacts attic R-values and energy performance. ...

The advice starts with "don't ever do this" and then dives into the details for doing it right: slope, overhangs, pedestal systems, step-down from house to deck, and truck liners. Wait, what? Jake describes a long-past project involving a spray-on truck bed liner protective coating (and there actually ARE spray-on residential roof systems for decks—who knew?).
