![]() ![]() The old saying, “a chain is only as strong as its weakest link,” applies to hurricane straps.įor the load transfer to be successful, a hurricane tie must provide a secure connection from the top of the roof to the wall joists.Ī tie that does not engage the top chord of a truss, for example, could allow wind to pull apart the uppermost section of the roof. This means that if a strong upwind impacts the roof, the tie will transfer the force from the framing of the uppermost parts of the roof through the walls to the foundation, creating a much stronger structure that will resist upwind forces that could lift the roof off.Ī hurricane tie consists of a piece of heavy gauge galvanized or stainless steel that connects to the joists and top plates, to the rafters, or, in the case of a truss-style roof, to the top chords. The tie works by creating a structural load connection that transfers forces made to the top of the building all the way to its foundation. You’ll also find them in the midwest in homes that face the risk of tornadoes. Hurricane ties are standard in states that experience annual hurricane threats, such as Florida, Louisiana, and coastal communities in the southeastern U.S. This prevents high winds, such as those experienced during a hurricane, from lifting off the roof off the structure.
