Not that this is a good thing by any means, but hurricanes sure can put a lot of people to work. Like Bamamav mentioned about the shingles, when Charlie hit down here you couldn't find a roofer, carpenter, electrician, etc that wasn't booked out a year in some cases.
I was in the boating business and we made a ton of money selling replacement canvas, rails, windshields, and every other part that was damaged on all the boats down here. The insurance companies weren't even questioning those repairs because they had millions of dollars going out for homes and businesses that were destroyed so the boat claims were relatively small potatoes.
Every week I had trailer trucks showing up with stuff like complete interiors, windshields, etc and it got so that we didn't have room to keep it until we got around to doing the labor on the boats. It's a hell of a way to make money, but it is just one of those things that happens.
