Roof Strength: Are You Connected In The Right Ways?
Damage from high winds, whether from hurricanes, thunderstorms, tornadoes or tropical storms, can occur anywhere in the country. The connection between your roof structure and the walls is one of the most important connections in your house to reduce damage from high winds. It’s also the first link in the continuous load path that is important in achieving the strongest, safest house possible. Creating a continuous load path means tying the roof to the walls and the walls to the foundation.
Why is this important? If the connections between the roof and walls are weak, these wind forces may cause the roof and walls to give way. Once the roof blows off, the entire structure can collapse within seconds. See how vulnerable a house can be without the right connections in this video of testing at the IBHS Research Center.
Placement of Connectors
The illustration above shows where metal connectors are recommended to create a continuous load path. Several construction hardware manufacturers provide a variety of connectors, like the ones shown below, that will accommodate most conditions.
