You already know that taping windows provides no protection whatsoever from flying debris and just cracking windows actually increases your risk of a catastrophic roof failure.Now let’s tackle the idea that only selected openings should be covered during a hurricane or severe weather.
Protect only the windows and doors facing the ocean.
Wind can come from any direction or angle and may change direction quickly. Tropical storms and hurricanes are large circular systems. As the eye of the storm passes your house, the winds may change direction up to 180 degrees, depending on your proximity to the eye. Protecting windows, entry doors, and garage doors with tested and approved shutters or impact-resistant windows is the best way to prevent damage from flying debris or wind pressure. If no system is in place, use 5/8” plywood as an emergency board-up measure, but be sure to use appropriate attachment methods or the plywood could become windborne debris and increase damage potential.
