Sketchup Roof Tutorial Here, I demonstrate how I make and complete a typical roof in Sketchup. This particular roof has both a gable (2 gables) and a hip. Also, you learn how I make sofits and incorperate chimneys. I was going to create a dormer but I ran out of time. I didn't watch the clock and I had plans... BUT, I actually get to show you everything I intended to show you. Enjoy and I hope this helps.
