Your mention of hurricanes, and parents who might be safely assumed to be retired, makes me think Florida. With that big bag of assumptions (throw out what follows if those are wrong), I'll remind folks that anything built in the last ten years is going to be very much regulated on how it's built. It'll be made of reinforced concrete block and the roof will be firmly tied to the rest of the house. The builder has no say in this. I'm not saying that given the choice the builder would choose the cheaper route, but a Florida house that laughs at a hurricane is due to government regulation more than the builder's choice of materials.

That, and Florida hasn't really had a decent hurricane in the last ten years.
