What do you consider best practice when venting a metal roof while also building a conditioned attic space? Master Builder Matt Risinger walks you through the process to ensure you can still have the best of both.

Here you can see how they installed 1x4 lath on the roof deck to form a venting space, so the air flows from the vent and out through the top of the ridge.Risinger explains the layers of insulation to make sure they are still building a high-performance, energy-efficient home.
