I'm currently building a new 2400 sqft house. I'm going to do a stucco roof. However I'm going to fiberglass the roof first, turtle shell the house. I'm going to put down 4" thick 2lbs styrofoam over fiberglass adhering it with polyurethane glue. The testing I've done I've used Quikrete foam coat mix. I will do a base coat, then a colored design pattern. Lastly I will use a acrylic masonry sealer. The purpose is to make a roof that is isulated externally and it should never leak.
