How do hurricane clips work?
Hurricane clips are an effective way of securing potentially hazardous parts of your home in stormy weather. These clips work by further strengthening the bond between the roof and walls of your home. Roof-to-wall connectors (clips) add a tested, proven, and surprisingly large degree of resistance to wind gusts and steady storm force winds.
What are hurricane clips for roof trusses?

Winds apply pressure to the walls of buildings. Winds passing over the roofs of the same buildings try to lift the roofs. Most of the time, the methods used to attach the roof rafters or trusses to the walls are strong enough to resist these uplift forces.
What happens if a fire breaks into a fire rated wall?
If the fire breaks into the fire-rated assembly, the combustible wood and other materials inside the assembly will char and burn; weaken the connections provided by the nails, the gusset plates, and the hurricane ties; and cause the rapid failure of the fire-rated floor-ceiling or wall assembly, causing structural collapse.
Do hurricane clips affect fire resistance?
Their use is required by building codes in areas subject to earthquakes, even if storms with high winds are rare. Please note that hurricane clips or seismic ties do not affect the fire resistance of a wood-frame building.
How effective are hurricane clips at protecting your house?
Between 50% to 70% of hurricane induced losses are due to roof failures. Hurricane clips are mandated for new construction, additions, and remodels. They are urged by hurricane insurers for existing homes built before 1994 in Hawaii (1994 is the date that the code was fully enforced). The simple explanation is that roof to wall connectors (clips) add a tested, proven, and surprisingly large degree of resistance to wind gusts and steady storm force winds. In other words, it is proven, especially for Hawaii's single wall houses which have little resistance to the push of side force winds that once your roof frame (the lid on the box) starts lifting the walls then are free to flex, bend, and collapse. This starts with only a couple of inches of side force dislocation because that is usually enough to cause the windows to break or blow out. Once the winds have access to the inside of the house then it finishes off the lifting of the roof.
What are hurricane clips?
Hurricane clips are steel connectors that have been designed, tested, and mandated by all building codes for new construction to connect your roof structure to your wall structure. When the tropical storm or hurricane winds hit your walls they are forced upwards to the over hang of your roof. Hurricane clips have passed rigid international lab testing and they are shown to quadruple (4x) the hold downforce at the junction of the roof and wall. In equivalent terms, just the basic hurricane clip installation is like parking 8 to 12 full size SUV's around the periphery of your roof as a hold down.
What is Hurricane Protection?
Hurricane protection is structural strengthening of your residence to better resist the steady force and strong gusts that occur for hours during a tropical storm or hurricane. Hawaii is different than every other coastal state because Hawaii has mountains and valleys and is susceptible to hurricanes from the East, West and South. Due to the warming of waters on the north side of the Hawaiian islands in 2014 Hawaii was also susceptical from the north as two storms skirted the islands from the north side.
Where are hurricane clips installed?
On new construction they are installed at the roof to wall junction at the top of your inside walls behind the drywall. On existing construction, called retrofitting, they area installed on the outside at the top of your walls where the roof rafters exist the attic. They are unobtrusive looking, usually only 3 inches tall and 1 inch wide.
Are hurricane clips noticeable?
Surprisingly they are barely noticeable. That is because, first people barely look at the top of the wall on the outside. They barely notice existing electric wires, water lines, electric meters, etc. Secondly, they are painted to blend in. HPS has installed over 2.5 million hurricane connectors (ties and clips) in over 21 years of service Hawaii. They are so unnoticeable, we have even had inquiries about hurricane protection when it's already there.
How do hurricane clips hold up to Hawaii's climate?
HPS then coats each item with a 2x metal primer . Once the item is installed we then thoroughly apply a 100 percent acrylic latex paint coating to match the color of the surrounding walls and eves. HPS makes available up to a 25 year limited warranty which only requires that homeowners or town house project maintenance repaints the walls, including clips, at a minimum of every 10 years. If near a sea coast, sprays the connectors to wash off air borne salt build up every 2 years.
Who says hurricane retrofits are worthwhile?
The property insurance industry thinks so. They know that the building codes throughout the coastal states and Hawaii are engineering based. In addition, states like Florida, Louisiana, and Hawaii invested hundreds of thousands of dollars into studies which proved the value and efficacy of retrofit hurricane protection.

Why do we need roof clips?
These clips and ties are typically installed on a home’s exterior to provide the most secure connection between the foundation, walls, and roof, ensuring the greatest possible resistance to upwind and lateral forces that could cause catastrophic damage to a building. They ensure that the roof system will not blow off during a hurricane.
How to hurricane proof a house?
When it comes to hurricane proofing a property, nothing should be left to chance. With hurricane season upon us, it’s important to ensure that all the safety components used are durable and weather resistant. Using a variety of fasteners to secure a roof and timber frames / structures is important if you want to avoid expensive property damage. A selection of durable stainless steel hurricane clips, ties, straps and joists are required for effective hurricane preparation. The role that these components play in hurricane proofing is as follows: 1 Hurricane connector straps – twist straps are typically used to create a tension connection between two wooden members. Their main function is to resist any sort of uplift caused by wind and also reduce any interference that can occur at the transition points. These are typically available galvanized or in stainless steel. 2 Hurricane joist hangers – these are used to create a stable connection between your roof trusses and rafters and top of your wall. They are designed to offer strong wind resistance and ensure that the task of hurricane clips and ties is made a bit easier in keeping the roof attached to the structure. 3 Hurricane clips and ties – ties and clips are used to create a sturdy and strengthening connection between the roof truss and building wall. Clips and ties are available in a variety of sizes and will provide impressive wind and seismic resistance.

When you've installed all the clips, it's important to go back and do a final check?
When you’ve gotten to the end and you’ve installed all the clips, it’s important to go back and do a final check. Doing this allows you to make sure you didn’t miss any nails, check that the clips are connected in the right places, and ensure everything is secure.
How much load can a hurricane tie hold?
If your building’s roof trusses have an uplift of 600 lb. at each end, don’t select a hurricane tie with a published capacity of less than 600 lb. It’s also important to consider combined loading if you plan to use the tie to resist both uplift and lateral loads. When the connector is resisting lateral loads, its capacity to resist uplift is reduced. I won’t go into too much detail on this topic since it was covered in a recent blog post, but in lieu of the traditional unity equation shown in Figure 1, certain Simpson Strong-Tie connectors (hurricane ties included) are permitted to use the alternative approach outlined in Figure 2.

Check with your insurance provider for additional information and requirements.
Can you use multiple hurricane ties?
What if the tabulated loads in the catalog for a single connector just aren’t enough? Use multiple connectors! An important note on using multiple connectors, though: Using four hurricane ties doesn’t always mean you’ll get 4x the load. Check out the recently updated F-C-HWRCAG16 High Wind-Resistant Construction Application Guide for allowable loads using multiple connectors and for guidance on the proper placement of connectors so as to avoid potential overlap or fastener interference.
