I made a square oven with a flat top out of fire brick. On the top back of the oven I constructed a square chimney. I built four fires, small ones the first two times and everything went well. On the forth time, I wrapped the oven with insulation to get more heat to stay in. This is when my roof collapsed. Would someone give me advice on how to rebuild my top? Should I use metal to support my roof? Where should I place my chimney or do I need one? Thanks
