Hurricane roof straps, resultantly, are the best way for a roof to resist upward and lateral forces caused by extreme wind conditions.Īlthough the majority of newly built homes in hurricane-prone areas are built with hurricane straps, this is not the case in older homes. This means that the roof structure is less likely to blow off and cause further damage to neighboring properties. So, if the roof is properly secured, it should be able to fully withstand the forces of hurricane winds due to the strong connection which allows the load to be shared by the walls and the foundation. As a result, the entire structure is able to withstand the load of the wind, which puts pressure on the roof in an upward direction. What this means, essentially, is that the forces of the wind are transferred downwards from the roof to the foundation. Because the wall structure is naturally connected to the foundations, this creates a complete load path. Wind, which acts in the opposite direction to forces such as snow loads, can cause the roof to detach from the building structure.ĭue to this, the connection between roof and building structure becomes extremely important, as this connection can take enormous strain during adverse wind conditions such as hurricanes and tornadoes.Ī hurricane roof strap is usually made of galvanized steel or stainless steel, and it essentially attaches the roof structure to the wall structure. During any sort of windstorm, it is the phenomenon of uplift which needs to be considered, and this is where rooves can be extremely vulnerable. The metal hurricane strap itself simply connects each rafter or beam to the wall plate or the wall structure. Whichever name they are called by, and whichever form they are found in, hurricane roof straps are extremely important features in a roof. Hurricane roof straps are also known as hurricane ties, hurricane brackets, hurricane anchors, hurricane clips, and hurricane strips. While not necessarily commonplace in older homes in the US, hurricane straps are often a compulsory feature in newly built homes in hurricane-prone areas such as Florida, Louisiana, coastal South Eastern USA, and certain midwestern areas that are prone to tornado risks. This creates a complete load path between the roof and the foundations, allowing the force of strong winds to be shared throughout the structure instead of being withstood by only the roof. Hurricane roof straps (or clips) are steel connectors which attach the roof of the building to the wall structure. This is where hurricane roof straps come in. The upwards force exerted by strong winds, however, can be far more damaging to the roof of a building, and it can potentially cause enormous damage to neighboring properties as well. One often thinks of the structural integrity of a roof in terms of its ability to withstand the downward forces of snow loads. When it comes to the roof of your home, the inherent strength and ability to withstand adverse weather conditions lies in the weakest link.
