Roofs
The more pitched a roof is, the more susceptible it is to damage. Installing truss bracings can make them much stronger. They can be as simple as 2X4s that run the length of the roof, the center and near the base. 2X4s can also be attached in an "X" fashion from where the roof meets the outside wall, to the fourth roof truss.

Hurricane straps are galvanized metal strips to hold your roof on top of the walls. Check to see if your roof has them, and if not, get them. This may require a professional.

Exterior Doors
Extra strong bolts and latches for all doors and garage doors are available at building supply stores. Horizontal 2X4 bracings across each panel of a garage door or a retro-fitting kit from the manufacturer will greatly strengthen the door. Heavier hinges and stronger supports are also a good idea, especially on double wide garage doors.

Windows
Storm shutters provide the best protection for windows. A less expensive alternative is do-it-yourself plywood protection. If covering windows with plywood:

• Make sure wood is at least 5/8 inch think, exterior grade
• Drill four small holes in the center of the panel to allow for pressure relief.
• Overlap the plywood by about 4 inches around the window.
• Use lag bolts, anchors and large washers.
• Bolts should penetrate wall by at least 1 3/4 inches (use drill and wood or masonry anchors)
• Bolts should be secured 2 1/2 inches from the outside edge of the plywood, at 12- inch intervals
• Make each plywood panel so it will be easy next time to match it to each window.
• If a window is bigger than a 4' X 8' sheet of plywood, use 2 X 4 bracing across the middle and bottom of two or more sheets.

Special tape or film can also strengthen window glass, but is not nearly as protective as plywood or shutters.
