YOUR ROOF Hurricane straps help hold the roof to the walls. In the attic, inspect forstraps of galvanized metal. Go in the attic and see how well the roof sheathing, often plywood, is attached. If most of the large nails or staples coming through the sheathing have missed the trusses, your roof sheathing is improperly installed. This was a big problem during Hurricane Andrew.
Most double doors have a fixed door.
Check to see how the fixed door is secured at the top and bottom. The bolts that secure most doors are not strong enough. You can't peel back your roof or remove the walls to see how your house was built. The safest option is to hire someone to inspect it for you. Winds of more than 100 mph will pull turbines off, leaving a hole for rain and wind to enter your attic.
