When strong winds blow, manufactured homes need special protection. No matter where you live, you need tie-downs and anchors to keep your manufactured home stable and secure. Before you start the job, you should understand why this wind protection system is necessary, and know the basic requirements for tie-downs and anchors. You also need to become familiar with all the components that make up your anchoring system. It’s a good idea to consult with an experienced professional installer or building inspector if you have any questions or doubts about the installation.
Manufactured homes must have anchors and tie-downs to keep them in place during high winds. Compared to site-built homes, manufactured homes are relatively lightweight. They have flat sides and ends, and they are built on frames rather than foundations. Almost all manufactured homes are elevated, situated on top of some sort of pier or foundation system. Wind can get under the homes and lift them up. In addition, the wind passing over the top of your manufactured home can create an uplift force.
To resist wind forces, you need two different types of tie-downs. In older homes, a vertical or over-the-top tie-down is needed to compensate for the uplift force. A diagonal or frame tie-down is needed to compensate for both lateral and uplift forces. Singlewide manufactured homes need both types of tie-downs. Doublewide homes only need the diagonal ties.
