Rental Property on Fire

[Jeffrey Hanlon]

I just got a call 5 minutes ago from my tenant telling me that my rental property is on fire. The fire started in the property adjacent to it from a roofer doing work. Now my property is currently on fire. I'm stuck an hour away and am besides myself. My quick question is....I'm assuming the property owner next to mine is responsible??? I'm assuming I need to close the roof up once its done and then work on the insurance companies?? Anyone else ever been in this situation? Thanks!
