Having worked several natural disasters, I can tell you the best manner of advertising in the 'Ike' market is word of mouth. Of course, you have to have a project prior to getting referrals. Landing the first project can be done by use of jobsigns, door hangers, truck signs, small area mailers, and eating breakfast at the local greasy spoon every morning, chatting with the patrons, handing out cards, and always wear a nice company polo. I have found that people have actually stopped us filling up our trucks to get business cards, and I try to set appointments at that time.
Some other tips. Make certain you have a very professional appearance, professional literature, business cards, informative website, and a respectful crew. As we work a lot of disasters be it hail or wind, we only work in Texas, so I am not certain as to whether we qualify as 'stormers'. One thing I can tell you is that people are on the defensive for any out of town or out of state rip-off contractors. The media has driven this home as well. If you are a professional company, do what you say you will do, put out a quality product, then you will do fine and make very good monies if you can stay on the insurance side of the game and not get into too much competitive bidding. Storm chasing companies are just like all other contractors....there are very good teams and usually a smaller percentage of very bad ones. The extra help is usually necessary in these situations b/c locals cannot generally handle the volume in such a short time.
The expenses in CAT work are very high. Be prepared to pay upwards of $100.00 per night for a motel 6 (if you can find one). Your men will expect a per diem amount daily anywhere from $25.00 to $40.00 per day for meals. The GC/Remodeler/Roofing Co. will generally cover all hotels, gas, per diems, etc. for all employees, so make sure you have adequate cash flows or it could be a disappointing trip back.
Good luck and I wish you the best.
