How to use roof ties to protect against uplift with Bob Vila

In this how-to video, Randy Shackelford of Simpson Strong-Tie joins Bob on site at the storm-ready house in Punta Gorda, Florida. Shackelford looks at an assortment of ties for new and retrofit applications with masonry, trusses, girders, and joists. He starts with the embedded truss anchors that were wet set four inches deep in the poured concrete walls. As the trusses are positioned, a truss anchor wraps around and is nailed to each truss, tying it directly into the reinforced walls of the house. When Bob questions retrofit applications, Shackelford shows him a specially developed truss anchor that is screwed into existing masonry before being wrapped around and nailed to the trusses. He also shows Bob basic truss anchors that are designed to combat up to 1,500 pounds of wind uplift and heavy girder connectors that can carry as much as 5,000 pounds in wind loads.
