What is the function of a tornado resistant roof?
A tornado-resistant roof’s primary function in a continuous load path is as a horizontal diaphragm that moves the loads imposed by heavy winds to the supporting walls below. The roof sheathing is the first structural element in the load path between the roof system and the foundation. The sheathing works with the roof framing to transfer lateral loads to the home’s shear walls.
What is roof framing?
Roof framing is the next building element of the load path. Sizing of the rafters of a roof’s frame must resist the weight of the roof system. The roof framing must also move the lateral loads to the shear walls below. It is essential in tornado-resistant roof design that the roof sheathing and framing are built and sized for the potential wind forces of the specific region.
What happens when a tornado hits a building?
Building failures during tornado events often start with damage to the roof. First, the wind blows the shingles from the roof sheathing. Then, the roof sheathing rips from the roof framing. Finally, the roof framing pulls from the supporting walls.
