Build Science 301 – Ep. 10 | Over Vent Cut Roof & Unvented “Monopoly” Truss Roof

From The Build Show.

What if your roof vented above the roof deck sheathing—and made your control layers easier to connect? Steve and Matt dig into two advanced approaches that simplify continuity: the Over Vent Cut Roof and the Monopoly Truss Roof. From strategic overhangs to airtight taping details, these assemblies make high performance more achievable. Bonus insights on SIPs, reno vs. new builds, and a reminder that building science isn’t optional—you’re doing it whether you know it or not!
