Rafter straps1/9/2024 ![]() Hurricane ties are used to connect the wood and metal members of the walls to the rafters, ridges, beams, and purlins in the roof. This system gives the roof greater resistance against the upward wind force that could lift it off or the lateral force that could damage it in a hurricane. ![]() The load distribution goes from the roof to the top then bottom of the wall, and finally ends in the foundation. A hurricane tie works by connecting the joists to these support beams to create a continuous load path. The roof joist is a wooden structural framework installed perpendicular to the building beams to transfer weight from the roofing to the floor. They are essential in tropical regions particularly prone to natural disasters. Ties can be lifesaving additions to reinforced buildings and all other surrounding buildings. They provide high resistance to the immense upward and lateral air pressures of a storm. Hurricane ties have been tested and proven to secure roofs even in adverse conditions. That’s how much of an edge hurricane straps can offer in a hurricane. The removed tops can be propelled at speeds so high that they hit buildings in their path and damage property.Īccording to a roofing study reported by Treasure Coast Newspapers, an adequately reinforced and maintained roof can last 50-70% longer in a storm than an unprotected roof. In worse cases, strong uplift winds could even remove the roofs entirely and blow them in the downward direction of the wind. This is why the worst hurricane damage usually results in roof failure. These wind speeds are so high that a roof without extra reinforcement cannot withstand the air pressure. Hurricane winds can have speeds as high as 74 to 190 mph (119 to 306 kph). When a roof gets blown off during a storm, the effect is disastrous because the rest of the building is left without protection from the destructive high winds and heavy rains.ĭue to this, the chance that a building will get through a hurricane with minimal damage and hold up well after the storm largely depends on its roof’s strength. As with doors and windows, roofs are very vulnerable to wind damage. In a natural disaster, the roof is the structure’s first line of defense. Hurricane ties are crucial because they create additional protection for the frame of a building. In wooden roofs, they also prevent degradation and decay of the timber that could lead to structural failure of the building. The weight transfer in a building is only as strong as its weakest link, so hurricane ties provide stability at the joints in roof purlin plates, rafters, wall plates, and floor plates. The ties are used with nails, bolts, or screws to improve the structural integrity of roof work. Ties help ensure that the roof’s weight is evenly distributed so that in extreme wind, it remains firm without lifting off. Hurricane ties are most commonly added in the construction phase of the roof. They are used to strengthen various roof types’ frames and firmly connect the roof to the rest of the building. Hurricane ties are special connectors used in building houses. ![]() They make buildings more resistant to the effects of high winds, especially in areas prone to natural disasters. Roof and rafter hurricane ties, also called hurricane straps or strips, are galvanized or low-carbon steel connectors used to strengthen wood and metal-framed roofs.
