Most homes are built to hold the roof up, not down. To correct for the upward and lateral lifting forces of hurricane winds, builders install hurricane straps, clips and anchor belts, which can help keep a home's roof intact.
In a correct setup, galvanized straps securely attached to the walls and foundation keep the roof tied into the entire house.
- Cost: Inexpensive hurricane straps sell for as little as 50 cents apiece, usually by the box or in coils. A typical home could require hundreds of straps.
- Effect on home insurance: Can be significant depending on state and carrier.
- Pros: When installed properly on a new home, hurricane straps drastically reduce the threat of roof failure in high winds. They are easy to install on new homes.
- Cons: Retrofitting straps on an existing home can be difficult, time-consuming and expensive.
