We've had the home fireworks for many years in addition to the neighborhood legal ones. Several years ago one landed on our roof and our house caught on fire (back in '79 we had a shake shingle roof). Luckily, my father and brother were home so they were able to grab the hose and start watering it down until the fire department showed up. Just the roof was burned and the whole interior of our house had to be repainted, and other stuff due to the fire and water damage, but it was relatively small, thank goodness. About 5 years after that a nearby palm tree caught fire (on the cross street so not too close to our house).
