Urgent Question About Building in Hurricane We are looking at a Cat 4 or 5 possible direct hit. My office building is tilt wall construction warehouse. Each building is like 20 units with each unit about 4000 SQ feet. The roof is the normal metal roof and I think a 3-4 foot wall around the roof. AC units are on roof. Inside are two levels on one side and full 30ft ceilings to the roof on the other. There's two sliding metal doors, the mfg says can withstand 150-200mph winds. Any thoughts on the integrity of this building if we get a cat 4 or 5?
