Think of It Like a Chain

A chain is only as strong as its weakest link. Your house works the same way during a hurricane. Every connection from roof to foundation must hold. If the roof-to-wall strap fails, the roof lifts off. If the wall-to-foundation connection fails, the whole wall goes.

Straps Transfer the Load

When wind pushes up on your roof, that force needs somewhere to go. Hold down straps grab the roof truss and connect it to the wall stud below. Then another strap connects that stud to the floor or foundation. The force flows down the chain into the ground.

Every Truss, Every Stud

In Broward County, you cannot skip connections. Every single roof truss needs a hurricane tie. Every wall end needs a hold down to the floor below. Engineers calculate the exact forces and specify straps with enough capacity plus a safety margin.

Frequently Asked Questions

What is a hold down strap and what does it do?

A hold down strap is a metal connector that ties building components together to resist wind uplift. These galvanized steel straps connect roof trusses to wall top plates, and wall studs to floor framing below. They create a continuous chain that holds everything together when hurricane winds try to lift the roof off.

How much uplift can hurricane straps resist?

Common hurricane straps like the Simpson H2.5A can resist about 500 pounds of uplift force. Heavy-duty straps like the H10 can handle over 1,500 pounds. In Broward County with 180 mph design winds, engineers calculate the required capacity and specify straps that exceed the demand with proper safety factors.

Do I need straps at every stud and truss?

In Broward County high-wind zones, yes - every roof truss needs a hurricane tie to the wall below, and walls need connections to the floor or foundation. This creates the continuous load path from roof to foundation. Missing even one connection creates a weak point where failure can start.

What is a continuous load path?

A continuous load path is an unbroken chain of connections from roof to foundation. Wind uplift on the roof must transfer through straps to walls, then to floors, then to foundation, and finally into the ground. Every link in this chain must be strong enough. If any connection is missing or weak, that is where failure begins.
