In Florida, a wind mitigation inspection is performed by a licensed general contractor, building contractor, architect, engineer, building inspector or home inspector. The information gathered is presented on a standard wind mitigation form, OIR-B1-1802, commonly referred to as the 1802 form.
Miami-Dade County was the first in Florida to certify hurricane-resistant standards for structures which the Florida Building Code subsequently enacted across all requirements for hurricane-resistant buildings. Many other states reference the requirements set in the Florida Building codes, or have developed their own requirements for hurricanes ...
Wind on the roof surfaces can cause negative pressures that create a lifting force sufficient to lift the roof off the building. Once this occurs, the building is weakened considerably, and the rest will likely fail as well. To minimize this vulnerability, the upper structure ought to be anchored through the walls to the foundation.
Since 2008, any new homes built in a high risk zone are saddled with a wide array of state-set construction requirements that specify the shape and composition of a building's roof to the siding ...
The difference can be illustrated by the fact that an insulated attic floor is the primary thermal control layer between the inside of the house and the exterior while the entire roof (from the surface of the roofing material to the interior paint finish on the ceiling) is part of the building envelope.

The IBC's requirements are adaptable to all levels of required wind speed. [ 5 ] The term impact resistant is defined as shutters, windows, and doors that have been proven to resist the impact from large windborne debris (defined by the test standards as a 9-pound 2x4 lumber missile striking end on at 34 mph).
Although the negative pressure caused by high velocity wind flowing over a building roof can cause the roof to fail with the building envelope intact, [30] broken windows allow the air pressure to rise inside a building, creating an even greater pressure difference, and increasing the likelihood of roof failure. This pressure increase results ...
