Regardless of your roof type, hurricane straps are designed to help hold the roof to the walls. Ask your builder to install hurricane straps of galvanized metal. Don't wait until after your house is constructed; although some people attempt hurricane-strap installation as a do-it-yourself project, the straps are difficult to fit, and improperly placed, they can turn into sharp projectiles in a strong wind.
In high winds, double garage doors can pull out of their tracks or collapse from wind pressure. If garage doors fail, high winds can enter your home and blow out doors, windows, walls, and even the roof. Make sure your garage doors are reinforced at their weakest points; in most cases, this step involves installing horizontal bracing on each panel. If you’re building a new garage or installing a new door, use heavier-than-standard hinges and stronger center supports than standard.
