How to get insurance work

I started my company about a year ago and am doing well with repair work, that has been my main source of income so far. I would like to get in with some insurance companies to start getting repairs from them, I have no idea how to do this. Could someone point me in the right direction?

Where are you located?
How long have you been in business?
What kind of roofing do you do?
What are the city / county / state regs for your area?
