What Is a Hurricane Tie?
A hurricane tie is a small metal bracket. It connects the wooden rafters or roof trusses of your house to the top of the exterior walls. Builders use them to provide extra strength. They keep your roof attached to your house during high winds. You might hear them called hurricane clips or seismic ties.
The word hurricane comes from the Mayan storm god. The word tie comes from the Old English word for a cord or rope. Builders began using these metal connectors widely in the 1990s after major storms caused widespread roof failures. Before that, builders just drove long nails through the wood. Today, these metal ties are a standard part of modern home construction.
Why These Metal Clips Matter to You
High winds push against your house and create a lifting force. This force wants to pull your roof right off the walls. Hurricane ties fight against this uplift. They hold the roof down securely. This protects your family and your property during severe weather.
They also matter for your wallet. Many insurance companies offer discounts if your home has proper roof tie-downs. You can learn more about protecting your investment in our guide to Home Insurance. If you live in a coastal area or a place prone to tornadoes, local building codes require these ties. Even in calm areas, they add important structural strength to your house.
Where You Will Find Them in Your Home
You will not see these clips in your living room or kitchen. They are hidden behind your drywall. The best place to spot them is in an unfinished attic. Look at the edges of the attic where the slanted roof framing meets the flat top of the exterior wall.
You will see shiny, galvanized steel brackets hugging the wood. They usually have a twisted or U-shape design. Each bracket has several small nails driven into the wood. If you are doing work on your Roofing, a contractor might inspect these connections from the outside when the roof deck is exposed. You might also see them in an unfinished garage or a shed.
What to Watch Out For
Hurricane ties are very tough, but they can fail if they are installed wrong or damaged. Take a flashlight into your attic and look at a few of them. Keep an eye out for these common issues:
- Heavy rust: A little surface rust is normal in a humid attic. Thick, flaky rust is a problem because it weakens the metal.
- Missing nails: Every little round hole in the metal bracket needs a nail in it. Sometimes builders skip holes to save time, which cuts the strength of the tie in half.
- Loose gaps: The bracket must sit flat against both pieces of wood. If you see a big gap, the tie cannot hold the roof tight.
Costs to Add Them to an Older Home
If your house was built before the 1990s, you might not have these brackets. You can add them to an existing home. This process is called retrofitting. It is a messy job because the contractor has to crawl to the tightest edges of your attic.
The metal clips themselves are very cheap. They cost about 1 to 3 dollars each at the hardware store. The main cost is labor. You can expect to pay a professional between 800 and 2000 dollars to retrofit an average home. Keep in mind that ranges vary based on your location and how hard it is to reach your roof edges.
If your roof is already being replaced, the cost drops a lot. The roofers can add the clips easily from the outside. Read our guide on Foundation & Structure to understand how all the framing parts of your home work together.
