If you open windows during a hurricane than the rain blowing sideways (wets your carpet) and also gets under your ceiling and helps lift off your roof. Think aerodynamics. The wind blowing OVER your roof is putting pressure DOWN on it much in the same way wind flowing over race cars help push them down on the track.

No. Please don't add ignorance to this thread. Professor Bernoulli reminds us that air in motion has less pressure than stationary air. Any framing carpenter can tell you about the straps they use to hold the roof DOWN when the wind blows hard.

(When you have a house on stilts that lets air pass under it like the space under a car, you can take up the analogy again.)

Thank you, Normal. Yours was the 3rd confirming response. I will change my ways--your 'aerodynamics' explanation makes it very clear: wind IN/roof OFF!
