Wind mitigation is the implementation of certain building techniques in order to limit damage caused by intense wind.
A Few Facts About Windstorms and Wind Insurance
In 2006, Citizens Insurance, one of the largest property insurers in Florida, requested a 45% rate increase for wind insurance. Other insurers took similar actions.
In Florida, the portion of a homeowner's premium covering wind damage can be up to 70% of the total, depending on location.
Wind mitigation benefits homeowners, private insurers, and all levels of government.
Incentives for Wind Mitigation
In some states, homeowners can benefit from reduced insurance premiums. The Gulf Coast states, which are most prone to windstorm damage from hurricanes, have each considered mandating incentives to mitigate damage due to wind. Mississippi and Texas currently do not have such legislation, although Florida has been successful. Following Hurricane Andrew, Florida passed a law requiring insurance companies to offer their customers discounts and credits for existing building features and home improvements that reduce damage and loss from wind. In order to qualify for this discount, homes must undergo a certified home wind inspection. However, many Floridians do not know of this law.
Those with windstorm insurance can avoid a costly deductible. Deductibles for homes in hurricane-prone areas can exceed $20,000, meaning that mild to moderate wind damage might not be covered by insurance at all. If proper wind mitigation techniques have been used, these expenses can be avoided altogether.
Wind mitigation helps protect the home from damage. Even if a home is insured, it is always costly when a house is damaged, both for the homeowner and the insurer. Repairs can take months, especially during material shortages that follow massive destruction to entire communities, as was the case after Hurricane Katrina struck Louisiana.
Lenders in Florida require homeowners to carry windstorm insurance in order to be approved for a mortgage. Insurers may not provide windstorm insurance to homes that are vulnerable to wind damage.
Checklist for Wind Mitigation Techniques:
The following features can protect a garage door from wind damage:
opening protection: Glass doors and windows should be replaced with impact-resistant glass. They should be structurally attached to the building in order to prevent the entire window from popping out of its frame. Sliding glass doors are especially vulnerable to flying debris due to their large expanse. Once an opening is created during a windstorm, the pressure within the house can rise high enough to cause the roof to fail in areas of low pressure. The picture to the right demonstrates how these areas of low pressure can form.
roof covering: There are many kinds of roof covering materials, and some resist wind damage better than others. The most common roof covering materials in Florida are composition shingles and tiles. A key factor in roof covering performance is the method of attachment of the roof covering material to the roof deck. Nails, not staples, should be used to fasten these materi
