A wind mitigation is an inspection that is done to verify how the roof is attached to the home. This inspection can decrease the premium on an insurance policy, depending on the credits your roof qualifies for. If the roof is 2002 or newer, there would be an automatic Florida Building Code credit, as well as some possible additional credits, depending on the nail size, nail spacing, and clips or wraps used, etc.
A certified inspector would fill out the required 4-page state form, as well as take photos in the attic documenting the credits. This form would be emailed to the agency, and the appropriate credits would be applied to revise the premium. The inspection report would also be submitted to the insurance company as proof of each credit. Roofs older than 2002 can still qualify for some of the credits as well, just not the 2002 FBC credit mentioned above.
