Don't forget to designate a meeting place to use if you are separated. That means tightly covering all windows and doors to prevent the wind from entering. If you can keep the wind outside, you and your possessions will be safe inside. Garage doors are frequently so large that, during a hurricane, they can wobble and actually pull out of the track or collapse. Ideally, they should be equipped with steel bracing.
Many manufacturers sell wind rated doors, and retrofit kits are available at building supply stores.
Roofs are especially vulnerable during hurricanes, but there are ways to reduce your exposure before a storm strikes. Professionally installed hurricane straps are important because they bind your roof to the walls of your house, forming a single, strong unit. You should also have truss bracing running the length of the roof. Tile and gabled roofs need special attention too. Regularly inspect the cross braces, fasteners and clips holding framing and screening in place.
