Sorry to hear about your families loss, but happy to hear they escaped unharmed!
I want to second what Shaun said. As both the victim of a house fire, and a former volunteer fire fighter (10 years), make sure to properly secure any salvageable property. People will not think twice to pick clean what little a fire victim has left. The common attitude is, "who cares, they have insurance." But having gone through this myself, and having lost almost everything, it is nice to have a few remnants of a life before a fire.
I hope your parents can rebuild quickly.
