If your going to train in with a storm chasing outfit do some homework and find a good one. Have heard horror stories from both mexicans, adjusters, and salesman about some of the storm chasers out there.
Look on BBB, Angies List, do google searches, and finaly make sure they are licensed.
After a big hail storm there's a good chance an outfit will call you trying to team up that is as long as your a good standing licensed company. This may be another option for you to get into storming. From what I understand they bring in salesman/estimators, crews, and the staff to go pound on doors to secure jobs. They typicaly give you a kick back in most cases it's a flat rate or a percentage of the job.
I had roofed for 10 years before learning about insurance work. In the past did insurance jobs but just gave them my bid which always meant the home owner was putting cash in their pocket. Only once did I bid higher than the insurance company, and they paid it! Back in 06 subbed from a large local storm repair company and learned enough to do it on my own after one Summer.
Another option is to hire a well trained highly skilled salesman. Most know the ins and outs of the insurance world in regards to hail and wind damage. Most however work for well oiled storm chasing machines and make $100-200K a year. Have had a few offer to sell for me but at the time was booked solid with 2-3 crews and didn't want to take on more liability. Looking back should have done it and just hire more good crews. The trick after a hail or big wind storm is to get as many jobs as possible (that you can do in one roofing season) because a year or two later they will all be done.
