As others have noted, it is the humidity that is the killer. In most bad hurricanes, your home is going to leak some amount of water if you are in this region and take a direct hit. Doesn't matter how fancy your roof is. Something is going to leak. Absent some external miracles, your HVAC system is the fastest way to dry out your house after it gets absolutely wrecked in one of these storms. The only way, even. To be clear, my setup is for the aftermath. I am not expecting to ride through a hurricane with my portable genset sitting in the back yard chugging along.
